General description
The YLCC water chillers and YLCC-H heat pumps are supplied factory-assembled and with all refrigerant piping and
interconnecting wiring ready for installation at the job site.
After assembly, the water chillers go through a water test.
Possible leaks are also checked once the refrigerant is
charged.
The units are made of galvanized steel with anticorrosive nuts
and bolts. The panels can be removed for access to internal
components. The outer galvanized steel parts are painted
with oven-dried enamel (RAL 9002).
Throughout the manufacturing process, all our products follow a quality control process in accordance with the ISO 9001
standard, which is also demanded from the acquired components. The PED pressure equipment directive is also applied.
The water chillers or air-water type heat pumps are designed
to be installed in air conditioning systems or industrial processes that require cold (or hot) water or water with glycol.
Designed for indoor installation.

General information
This accessory controls condensing pressure in the winter
cycle by varying air flow through the outdoor coils. This flow
variation keeps condensing pressure constant when outdoor
temperatures are low.
Operation
By means of the pressure detected through the analogical
pressure switches installed in the cooling circuit, and carrying out the appropriate calculations as programmed, this control generates an analogical signal that opens the dampers
to maintain the condensing pressure previously programmed
as the set point.
Anti-vibratory supports
Whenever a maximum reduction of vibration and noise generated by the unit is required, a set of steel spring anti-vibratory
supports can be used. These should be installed between the
supporting frame of the unit and the base or floor where same
is to be located. This base should be solid and sized in accordance with the weight to be supported. 12MA bolts are
use to secure the supports to the base of the frame. This antivibratory support accessory for YLCC-42/62 includes 4
springs, whereas for YLCC-82/102/122/152 it includes 6. These
spring supports should be distributed and secured by means
of the corresponding holes drilled in the chiller base, the location of which is detailed in General Dimensions.
Remote control (accessory)
For access and control by means of the buttons and LEDs
available. Allows selecting the cool, heat and OFF functions,
and the red LED indicates any failure.
Can be installed at a maximum distance of 50 m. The remote
terminal should be connected to the unit with a 7 x 0,35 mm2

the solution, an even lower freezing point can be achieved
and this protects the circuit when the unit is off and ambient
temperature is low (below 0° C). This table indicates freezing
point in accordance with glycol concentration. This concentration appears in % per weight.

Factors with water and glycol
Glycol can be used for antifreeze protection, or as brine for
operation at low temperatures. We recommend the use of
water and glycol when the discharge water temperature is
below +6° C. The “Solution with glycol/freezing point” table
gives the freezing point of water with glycol, and the “Recommended glycol concentration” table shows the glycol concentration needed, depending upon application.
Glycol contains anticorrosive and antifoam components that
favour circuit protection.

Installation instructions
General information
The YLCC water chillers and heat pumps are factory-charged
and tested packaged units.
Attention: Do not touch hot surfaces.
Inspection
Upon reception, inspect the goods and notify the carrier and
the insurance company, in writing, of any possible damage
during transportation.
Environmental protection
Attention: The unit is equipped with remote control and can start automatically. Two minutes prior to having access to the interior, disconnect the
power supply so as to avoid any contact with the fan turbine in motion.
Packing
Packing is made of recyclable material. Its elimination should
be carried out in accordance with local regulations on selective collection of residual material.
Elimination of the unit
Upon disassembly of the unit after a long service life, the
components should be recuperated ecologically. The cooling
circuit is full of refrigerant, which should be recuperated and
returned to the gas manufacturer for recycling.
Oil will remain in the hermetic compressor and, therefore,
must be returned with its circuit sealed.
The air conditioning unit will be deposited in an area determined by the local authorities, for its selective recuperation.
Attention: Lifting point.
Warning signs
The following signs indicate the existence of potentially dangerous conditions for users or servicing personnel.
Whenever found on the unit itself, take the meaning of each
one into account.
This symbol indicates an electrical danger
or risk.
Transportation
The units should always be transported in vertical position
so as to avoid oil leaking out of the compressor. If, for any
reason, this position need be changed sporadically, they will
remain in that position a strictly necessary period of time only.
To move the units to their final location, the four rectangular
openings in the bed frame can be used with a forklift truck, or
the four cylindrical holes at the ends of the bed frame for
elevation.

temperature is below the set point.
Clearances
When installing each unit, clearances should be left for:
1- Air intake and discharge.
2- Water, drain and power supply connections
3- Maintenance servicing.
Note: See minimum clearances indicated on the general dimensions diagrams.
Drainage
The unit has two connections for draining condensed water
accumulated in the coil during operation in the winter cycle,
or for fully emptying the unit. The outer diameter of these
connections is 28 mm. At outdoor temperatures below 0° C,
condensed water can freeze and obstruct the drain. It is advisable to take this into account and, when considered necessary, install a flexible electric heater. This heater can be
connected by means of an ambient thermostat set to 3° C,
for example. This thermostat activates the heater when the
Locating and securing the unit
These units are designed to be placed on the floor indoors.
With air discharge and return ducts, if necessary. Before opening the packing, make sure you have received the appropriate product by checking the specifications described on the
outside of same.
The unit should be placed on a perfectly horizontal plane,
making sure the base can support the weight of the unit.
If vibration-free operation is required, the unit can be placed
on a cork or similar anti-vibratory base, or fastened to the
base with anti-vibratory plates or supports (optional accessory).
If the unit is to be placed on the floor, a concrete base should
be prepared so as to distribute weight evenly.

Hydraulic connections
The hydraulic connections of the water intake and outlet of
the chiller should be carried out respecting the intake and
outlet directions indicated at the front of the unit.
An iron (not galvanised) or copper tubing can be use, with
dimensions no lower than those indicated, and keeping in
mind the pressure drops of the indoor exchanger and of the
installation.
Pump dimensioning should be carried out considering a nominal flow that allows the ∆t of the project within the limits of the
unit: min. 3° C and max. 7° C. The head pressure of the pump
chosen must cover the pressure drops of the installation plus
the pressure drops of the chiller.
It is convenient that the tubing connection be carried out by
means of anti-vibratory couplings.
In all cases, a flow switch must be installed so as to avoid the
possibility of operation without water circulation, as well as a
water filter (both are obligatory for warrantee application).
In the water feedback tubing, an expansion vessel adequate
to the total volume of the water in the installation should also
be installed in the unit.

During the winter season, with outdoor temperatures below
0° C, precautions should be taken to avoid the water from
freezing in the tubing networks and inside the inner chiller
exchanger.
The following solutions are usually applied:
a) Drain the circuit.
b) Fill the circuit with an antifreeze mixture (glycol).
c) Keep the circulator in constant operation.

Application to YLCC/YLCC-H units
To avoid discomfort caused by a water temperature drop in
the defrost cycle, or tripping of the antifreeze thermostat in
small volume installations, it is necessary to use an accumulator tank to increase the thermal inertia of the installation.
Water volumes of the GH kits and their compatibility with the
YLCC/YLCC-H units are as follows:
These flow switches can be used on water or glycol circulating tubing. They are designed for locking; that is to sea, protection against a lack of liquid circulation. The switch is to be
mounted on horizontal tubing, in a section having a straight
run of at least five times the tubing diameter on each side of
the flow switch. Do not install near valves, elbows or openings. Installation should be such that terminals are accessible for easy connection. The switch is marked with the flow
direction. For 1" tubing, mount the switch on a standard 1" x
1" x 1" tee joint. Use a reducer tee on larger size tubing to
keep the flow switch set to same and achieve an adequate
length of the tab in the flow current. Example: use a 2" x 2" x
1" tee for 2" tubing. If a standard tee is used, install a buffer or
sleeve at the top of the opening. Adjust the tab length to the
tubing size. For 1", 2" or 3" tubing, us the tab segments supplied. For example: for 2" tubing remove the 3" tab; for 1 ½”
tubing, cut the tab to the tubing size or use the 1" tab.

Nevertheless, in each case the minimum volume needed for
the installation should be checked.
Circulating pump
For satisfactory operation of the units, it is essential to select
an adequate pump to supply sufficient flow and pressure to
the hydraulic circuit. Use the following table for this purpose.

Flow switch
The hydraulic circuit to which the unit is connected is equipped
with a flow switch that avoids operation of the air conditioner
without sufficient water flow. The installation of this switch is
absolutely indispensable, as well as checking correct setting
and operation during installation commissioning.
L/min. flow values needed for switch operation
No part of the tab should touch the tubing or narrowing points
of same. Screw flow switch on in a position in which the plane
of the tab is in right angle to the flow. The arrow appearing on
the side of the box should point in the flow direction.
Setting
This switch is factory-set approximately at the minimum flow
value (see “Flow values table”). To achieve a higher flow value,
turn the adjusting screw on the scale clockwise.
Flows
This table shows adjustable flows based on real test data,
using 1", 2" and 3" vanes for 1-6" tubing. The differential (difference between ON and OFF) depends upon flow conditions. (Flows for “flow increase” that appear in parenthesis
are predetermined values.)

Operating and start-up instructions
YLCC and YLCC-H control system
The YLCC and YLCC-H-42, 62, 82 and 102 (two separate
compressors and two cooling circuits) is a multipurpose controller programmed for use with air-water chiller and heat pump
units.
Standard components
- System and first cooling circuit control base plate. This
is the central nucleus that processes the signals coming
from the probes and protection elements of the entire system. Directly receives the signals from the first circuit and
controls its active elements: compressor 1, fan 1, 4-way
valve 1, water circulating pump, alarm relay and antifreeze
heater 1 (if installed). 24 Vac.
- Second cooling circuit expansion and control board.
This is an expansion of the base plate to be connected by
means of a specific connector. Receives the signals from
the second circuit and controls its active elements: compressor 2, fan 2, 4-way valve 2 and backup heater 2 (if installed).
- Local terminal. For accessing and controlling the system
by means of the display, keys and LEDs. Allows selecting
cool, heat and off functions. Also allows changing operating parameters, as well as monitoring the system. Can be
installed at a distance of 2 m. from the base plate. Is included inside the control panel and is to be connected to
the base plate by means of an 8-lead telephone cable.
- Fan ON/OFF control module. Used on heat pump units
with centrifugal fans equiped with three-phase motors with
on speed control. These modules should be connected to
the base and expansion plates respectively. They act directly upon the fan contactor.
- NTC probes. 5 NTC probes are used to read system temperatures. One is located at the common water intake of
the two evaporating units, another two at each water outlet
of said units, and the remaining two at the coil to control
defrost cycles. (On cooling units, 3 NTC probes are used:
one at water intake and two at water discharge).

Unit addressing
Unit addressing within the network can be selected by means
of the value given to parameter HA and the dip-switch system configuration included in serial board RS485. Effective
addressing is obtained by adding the offset value taken from
the following table to HA.
For example, if the HA value is 12 and dip-switch 1 is set to
ON, the address obtained will be 12 + 128 = 140.

when pressed two at a time, are detailed below.
Activation/deactivation of “COOL” function
The COOL function can be activated and deactivated by
pressing the COOL key for over 5 seconds. It is impossible to

The display always shows, by default, the return water temperature detected by probe B1. This comprises three figures
with automatic viewing of a decimal point between -19.9 and
+19.9° C. Beyond this range, the displayed value will always
comprise two figures. E.g. 21° C. Nevertheless, the regulator
in the internal program always operates based on tenths of a
degree.

The yellow LED indicates unit operation. Under normal conditions, it flashes once per second. In the case of an alarm, it
flashes twice per second. When it goes off, no voltage is reaching the base plate.
The green LED indicates communication with the remote terminal. In the case of a communication failure, this LED remains off (failures are normally due to bad contact between
the telephone connector and one of the female bases on the
main board or the terminal.

unit. In the air cooled condensing unit, heat exchange takes
place between the air and the refrigerant. The air is heated
and removed from the chiller (heat rejection). The refrigerant
is condensed and subcooled. Then the refrigerant (liquid) goes
on to the expansion valve where it is expanded down to the
evaporating pressure is reached, and then goes on to evaporating unit to begin a new cooling cycle.
Heat exchange takes place between the liquid (water or water
and glycol) and the refrigerant in the coaxial heat exchanger.
The water is cooled and the evaporates refrigerant. Then the
Scroll type compressor compresses the refrigerant (gas) until
the condensing pressure is reached, which then goes on to
the air cooled condensing unit. In the air cooled condensing
unit, heat exchange takes place between the air and the refrigerant. The air is heated and removed from the chiller (heat
rejection). The refrigerant is condensed and subcooled. Then
the refrigerant (liquid) goes on to the expansion valve where it
is expanded down to the evaporating pressure, and then goes
on to evaporating unit to begin a new cooling cycle.
Heating cycle YLCC-H
In heating mode this cycle is inverted. The 4-way valve is
activated. The condensing unit becomes the evaporating unit,
and the evaporating unit becomes the condensing unit. The
water is heated in the coaxial heat exchanger.
Cooling cycle YLCC-H
Defrost
When the probe detects a temperature below 0.5° C (factoryset freezing point), this cycle is inverted. The defrost cycle is
activated for a maximum of 4 minutes. If, during this period of
time, the temperature rises to over +6° C, the defrost cycle is
deactivated.
The 4-way valve is not activated. Heat exchange takes place
between the liquid (water or water and glycol) and the refrigerant in the coaxial heat exchanger. The water is cooled and the
refrigerant evaporates. Then the Scroll type compressor compresses the refrigerant (gas) until the condensing pressure is
reached, which then goes on to the air cooled condensing
