AHT Cooling Systems GmbH
1 General specifications
Before installing and using this cabinet for the first time, the
locally applicable regulations stipulated by trade law are to
be observed.
ATTENTION: In all effective refrigeration, condensation
water is precipitated or the moisture held in the air is
frozen onto the refrigerated surfaces. This build-up of
ice is automatically defrosted by the (-) AD cabinets in
regular cycles.
AHT cabinets are free from PCB, PCT, asbestos,
formaldehyde, cadmium and substances that interfere with
wetness.
The defrost water which accumulates is led via a
drainage channel out of the inside of the cabinet into
the machine space and evaporated.
The refrigerant R404A (44% R125, 4% R134a, 52% R143a)
is covered by the Kyoto Protocol and has a global warming
potential (GWP) of 3784.
The build-up of ice caused by any leaks in the
defrosting drainage channel does not affect the
function of the cabinet.
Airborne sound emissions of the units < 70 dB(A)
In the event of loud noises and/or strong vibrations in the
unit, contact a service technician.
The weights of the units are given in the datasheets. They
can be obtained from AHT.
The function of the cabinets is not affected by bulges
which may occur in operation.
The built-in bars are required for the cabinet to function
and must not be removed. The bars are required to
distance the food from the wall of the evaporator during
the defrosting process.
The design of the individual cabinet types may vary.

The specifications on the “rating plate" are to be observed
for installation and maintenance. This plate can be found
on the back of the cabinet.
4 Unpacking and handling
The serial number, cabinet type and refrigerant can be
found either on the rating plate or on the sticker affixed
inside on the plastic frame at the back.
ATTENTION: To protect the cooling unit from damage,
the cabinet must only be transported and stored in the
operating position. Non-observance results in the loss
of the warranty.
3 Application
AHT units are designed for storing pre-packaged, frozen
foods which have already been frozen to the appropriate
temperature and pre-packaged frozen ice cream or frozen
ice cream stored in suitable containers. The cabinets are
not suitable for freezing fresh products.
Before the cabinet is unpacked and while it is being
unpacked, inspect visually to determine if there is any
transport damage. Please look for loose parts, dents,
scratches, visible fluid losses, etc.
Report any damage to AHT immediately. For the rest the
AHT terms of business apply.
ATTENTION: A use of the cabinet other than this or one
which goes beyond this is considered as not as
intended.
Before disposing of the packaging material, please check it
for any parts of the cabinet which have come loose.
The storage of any type of bottles is considered to be improper use for freezers. There is a danger of injury from
breakage. The Àawless condition of the refrigeration unit
and its proper use must be monitored regularly by the instructed operating staff. To that effect, the units must be
checked to make sure that products that have been stored
there by third parties (improperly) are removed.

Set the cabinet up in a well-ventilated place and so
that it is level.
Refrigerating devices discharge the heat they have
taken from the storage space into the ambient air.
Therefore the air circulation around the cabinets
should not be hindered.
Observe minimum distance when assembling in
blocks. (See diagram.)
The areas in between must not be covered

ATTENTION: Mains voltage and mains frequency
must match the ratings given on the cabinet’s rating
plate.
Work on electrical systems may only be undertaken
by qualified electricians. The relevant local safety
regulations must be observed.
Only thin film advertising stickers can be used. Do not
fix thick, insulating materials on the outer walls.
Avoid draughts and greater heat absorption at the
installation site. Do not place cabinets in front of
heaters and under air outlets.
6.1
Internal lighting
Do not point spotlights into the cabinets. Avoid lighting
with light bulbs as much as possible. Fluorescent lights
give off less heat!
Lighting is already incorporated into the cabinets with AHT
cabinets with an internal light. An additional light socket
must be available for each chest. No more than 8 internal
lights may be connected to one electrical circuit.
Any heat radiation into the storage cabinet leads to
increased operating costs and can influence the
cabinet’s performance.
ATTENTION: If the mains cable or light Àex
becomes damaged it has to be replaced by AHT or
AHT customer service.
This information must be taken as a suggestion. The
electrical supply company regulations and VDE regulations
for the relevant region must be noted and observed.
Electrical work must only be carried out by a qualified
professional.
When using light fixtures these may sometimes be
connected to each other using the sockets that are already
integrated. In this case you will normally only need 1 - 2
additional sockets for the lighting.
With the LAK model no more than 12 light fittings can be
connected to 1 fuse, with the LAL model no more than 18
light fittings and with the LA-A model no more than 8 light
fittings. No other consumer loads may be connected to
these sockets.
x
x
ATTENTION: You must ensure that no AHT cabinets
are connected to the lighting circuit.
x
ATTENTION: Do not expose cabinet to direct sunlight.
The cabinet must not be heated over 70°C (158°F).
6 Connecting to the electrical supply
The cabinet is a plug-in compact cabinet.
The power cable (white) is 175 m. long. With cabinets
with an internal light the lighting cable (black or light
grey, depending on the country) is 120 cm. long. Both
cables are located at the back right of the cabinet and
are marked when they are delivered (mains cable lighting cable).
The connection cable for the lighting is marked with a
sticker and is either black or grey (depending on the
country). It is very sensible to mark the light sockets
clearly to prevent them being confused with the cabinet
connector plug (light grey cable). Otherwise there is the
risk that the cabinets will be switched off when the
supermarket lights are switched off.

Cabinets should only be connected to shockproof sockets
with earth contact and their own mains circuit. No more than
2 cabinets should ever be connected to a circuit.
With cabinets with additional flex for interior lighting only a
maximum of 8 light flexes may be connected to a fuse.
AHT recommends using a cable channel on the floor with
sockets built into it or on top. The cable channel used must
not be any higher than from the floor to the lower edge of the
rear ventilation grid of the cabinet. Any other fixtures or
superstructures (e.g. shelves with longitudinal supports
above) that obstruct the dissipation of heat between the
cabinets must be avoided. Should fittings between the
cabinets be necessary anyway, written approval must be
obtained from AHT for the relevant design.
Power supply details
An FI circuit breaker is provided to install AHT cabinets in
the supermarket when the electrical installation is done.
No more than 2 cabinets must be connected to a safety
device like this. One safety device for each cabinet is

The cabinets must only be loaded up to the stacking lines.
The storage temperature set cannot be guaranteed above
the stacking line.
As prescribed by VDE100-410 in its current version (issue
dated June 2007) the use of a residual current circuit breaker (RCCB) as „additional protection for external areas and
sockets“ (411.3.3) is compulsory (as it already is in Austria
and Switzerland).
ATTENTION: It is possible that defrosting water may
escape from the unit. If this happens, it should be cleared up immediately to avoid the danger of a slippery
Àoor.
A separate safety fuse is appropriate for the lighting for
AHT cabinets.
Load dropping switches or cabinet cut off switches are not
permitted because malfunctions could occur as a result.
Should these safety guidelines not be observed claims
under the guarantee and/or for damages will not be
entertained.
ATTENTION: It is not permitted to operate the
cabinets without a lid or with the lid open.
All cabinets are equipped with glass lids as standard. The lids
are required for the correct operation of the cabinet. They
should only be opened for loading and unloading the food.
7 Using the cabinet for the first time
and function
Before being used for the first time (after installation – see
section 5) the cabinet should have a minimum
temperature of +16°C (60.8°F), otherwise the cabinet must
be adjusted to normal room temperature.
ATTENTION: When the operating voltage is switched
on (plug in mains plug – see section 6) the cooling
unit starts to work straightaway.
8 Operating the (-) AD cabinets
Despite the automatic de-icing, it is recommended for
hygiene reasons that the cabinet is completely
defrosted once or twice a year so that any ice build-up
can be removed and the cabinet interior can be cleaned.

symbols provides you with all necessary information.
The temperature is displayed by means of red LEDs in a 7
segment display, in which the value is displayed in 3 figures.
There are 4 buttons available as controls, which are
assigned as follows:
The glass lids are not intended as aids for reaching
the upper shelves or for storing miscellaneous
objects and are not equipped for such loads.
The (-) AD cabinets are set to a temperature of –19°C
(-2°F) in the factory. How to change the temperature value
is described in section 8.
The cabinet has automatic de-icing. The cabinet's de-icing
times are pre-set in the control unit. De-icing is
automatically initiated twice a week during the night. Deicing can also be initiated manually. Manual initiation of deicing is described in section 8.
The cabinets have a real time clock, which ensures that
de-icing starts correctly during the night. The time on the
clock is pre-set in the AHT factory. If the cabinets are not
operated for longer than 6 months, it is possible that the
time on the clock needs to be re-set. (This is discernible if
the cabinets defrost during shop opening hours.) This
means that the frost or ice build-up in the inner container is
defrosted and the ensuing water is fed away via the
discharge channel.
Should you notice that your cabinet is defrosting during
opening hours, please call a service engineer to re-set the
clock on the control unit correctly.
The food does not come to any harm during de-icing. The
temperatures stipulated by the standard are not exceeded.
In order to maintain good food quality, it is recommended
that frozen foods are only put into the freezers in the
period from 8:00 to 20:00

De-icing
In addition to the automatic de-icing, a manual de-icing
cycle can also be initiated.
To do this, the “MAN. DEFROST/SET” button must be
pressed briefly. “- d -” appears in the display for about 2
seconds and then “dFr.” is displayed. De-icing is now
active. It takes around 10 mins. until the ice on the inner
wall of the container starts to melt, beginning at the top.
After the de-icing cycle has run, the cabinet returns to
normal operation. The display then changes from “dFr.” to
the temperature display.
17
AHT Cooling Systems GmbH
After every de-icing cycle the manual initiation of de-icing
is blocked for 24 hours. De-icing cannot be manually
initiated during this time. If the cabinet does not react to
the “MAN. DEFROST/SET” button being pressed, the
cabinet has probably been defrosted during the night on
the time controller. While the button is being pressed “- - -”
is displayed in the 7 segment display.
Operation
Once the voltage has been switched on, the cabinet starts
automatically. During normal operation the cabinet’s
average interior temperature is displayed in °C.
If you press the "Standby / Reset" button for at least 1
second the cabinet will switch to standby mode. The
display shows: "- - -". If you press the "Standby / Reset"
button once more the cabinet will switch on again and the
internal temperature will be displayed. This procedure may
take a few seconds.
Despite the automatic de-icing, it is recommended for
hygiene reasons that the cabinet is completely defrosted
once or twice a year so that any ice build-up can be
removed and the cabinet interior can be cleaned.
Defrost start times with networking via bus
Defrosting is performed according to the factory setting,
beginning at 21:30. The defrosting day is allocated to a
group depending on the bus address and automatically
calculated by the control unit. This prevents all cabinets
de-icing at the same time.
The de-icing cycles are scheduled at 3 day intervals.

An alarm is shown by the display of an error message.
This error code is displayed alternately with the
temperature (flashing display). In addition there is the
option of emitting an acoustic signal from a buzzer (built-in
as an extra).
The temperature display shows a system temperature,
which bears no direct relationship with the product
temperature. The sensor is positioned on the floor of the
cabinet under the floor panel. Depending on the turnover
of goods, displays of as low as -25°C (-13°F) are possible.
Even if colder temperatures are displayed, this does not
mean that the cabinet is set at too cold a temperature, as
the product temperature at the loading limit is clearly
warmer than at floor level.
One short press of the "Stand By / Reset" button.
A single press of the “Stand By / Reset” button cancels the
acoustic alarm (if connected) and the error code is no
