CHARACTERISTICS OF THE DEVICE
2.1.
RECOMMENDED USE
RO-I is an equipment designed for dish/glass wash machine water tr eatment. It is able to modify
or ganoleptic and chemical char acter istics of potable water , r educing saline content.
RO-I is used to supply tr eated water to dishwasher and glasswasher machines.
ATTENTION
The device is not intended to be used by people (including childr en) whose physical,
sensor y or mental disabilities ar e r educed, or lack of exper ience or knowledge, unless
they have been gr anted thr ough the inter mediar y of a per son r esponsible for their safety,
super vision or instr uction concer ning the use of the device. Childr en should be super vised
to ensur e they do not play with the appliance.
ATTENTION
If the dish/w ash machine is not equipped w ith break tank, an external pressure tank
of at least 16 liters must be installed. (not needed !!!!)
All components of the dish/glass w ashmachine in contact w ith w ater must be
compatible w ith osmosis trated w ater.
It is forbidden to use brass; use only plastic parts and stainless steel parts.
The company Hobart is not responsible of any demage or injury to thing s or people if
these instructions are not respected.
ATTENTION
RO - I is not a w ater purifier.
Using RO-I to condition w ater that is not drinkable is ABSOLUTELY PROHIBITED.
2.2.
SCHEMATI C REPRESENTATI ON
SCHEMATIC REPRESENTATION
ATTENTION
The drain capillary must be replaced inside the machine, considering w ater inlet
parameters (see § 3.1.).

DESCRI PTI ON
The RO-I osmosis machine can be installed in thr ee differ ent exter nal housings for socket “GC” ser ies, or
socket “GX” ser ies or for r emote ver tical installation.
Ther e ar e thr ee exter nal hydr aulic connections on the back of the device, r espectively, for the inlet water
¾”G, the outlet water ¾”G to the dish/washmachine and the line used for dr ain off.
On the r ear side of the machine, ther e is also the power cor d, and air vents.
Fr om the connection to the main plumbing networ k, the water ar r ives to the inlet solenoid valve
The water flows then thr ough the quick connection car bon filter . The car bon block filter facilitates the
elimination of the unpleasant chlor ine taste, without compr omising the desir able miner al pr oper ties of
the water . These activated car bon filter s can also absor b potential tr ace or ganic micr o pollutants, var ious
chemicals  or ganic and inor ganic (i.e. chlor ine composites), chlor ine r esidue used to disinfect water ,
halofor ms, pesticides, sur face-active agents.
Befor e the filter , a min pr essur e switch is attached to check inlet pr essur e.
The min pr essur e switch pr events the pump to r un dr y. In chase of low pr essur e, alar m is acustic signalled
and then the machine makes automatic r estar t after one minute.
When consecutives low pr essur e alar m occur es, the r estar t delay automatically incr eases.
Water is then pumped at high pr essur e by the br ass vane pump connected to the liquid cooled motor . The
water ar r ives at high pr essur e to the vessels contain the r ever se osmosis membr anes. The water
per meates the layer flowing into the collection tubes, and then it is dir ected to the main tube of the
membr ane, wr apped in var ious layer s. The per meate yield comes fr om the main tube of the membr ane
and is sent dir ectly to the outlet.
The dr ain capillar y is used to set the dr ain flow and r ecover y r atio.
For automatic star t/stop of the machine, a check valve and a max pr essur e switch ar e installed in the
per meate line.
On the bottom and on the r ight side of the machine, ther e ar e two leakage pr obes (for ver tical and
hor izontal oper ating); if leakage occur s the machine stops automatically and makes acustic alar m.
The signal led infor m machine status: led on means machine functioning, led fast blinking means leackage
alar m, led slow blinking means low pr essur e alar m, one blink two seconds off means stand-by status.
W ARNING
The overall w ater quality depends on a number of variables: the concentration of
saline properties in the w ater, along w ith other retained elements, the temperature,
w ater pressure, and the total solubility of salt. The w ater quality may also vary
according to the kinds of salts or elements found in the local w ater source.
The treatment of w ater coming from a source that is particularly polluted w ith high
concentrations of impurities can cause the blockage of the membranes of the filters
and/or impede the overall w ater flow .
This device CANNOT be used as a substitute for a government approved desalinization
and anti-bacteriological plant.

FUNCTIONING
4.1
FI RST START-UP
W ARNING
The fir st star t-up of the machine must be done by the installer .
The installer checks the cor r ect functioning of the machine.
Inser t the power plug in a gr ounded socket 230V 50Hz; the machine is r eady to oper ate.
It is necessar y to fill the dishwasher once with the new installed RO-I and dr ain the
dishwasher one time completely.
Check any leakage in the hydr aulic cir cuit.
4.2
NORMAL USE
The machine star ts and stops automatically leaded by the inter nal max pr essur e switch when the
dish/washmachine downstr eam r equir es water .
W ARNING
Avoid dehydration of the membranes, as it w ill cause them to malfunction.
4.2.1 Automatic flushing function
In or der to avoid bacter ial gr owth on the sur face of the membr ane, the device will automatically oper ate
the “flushing” mode ever y 6 hour . This pr ocess consists of the substitution of stagnate water with fr esh
water (inside the membr ane). Dur ing this oper ation the solenoid valve will open for 2 minute.
4.3
LOW PRESSURE ALARM
The machine has a low pr essur e switch inside. In chase of low pr essur e, the machine makes thr ee BEEP
and stop the machine. It r estar ts automatically. The delay between automatic r estar ts is incr eased if
consecutive alar ms r epeat.
4.4
LEACKAGE ALARM
The machine has two leackage sensor s inside. In chase of leackage, the machine makes a long BEEP and
stop the machine. To r estar t the machine, disconnect and r econnect the power plug.
W ARNING
If leackage alarm repeats, disconnect the pow er, open the machine and check for
leackages.
Machine opening and leackage inspection can be done by qualified personell only.
4.5

The tasks of the enduser ar e:
- Filter replacement (every 200 hours of w orking)
ATTENTION
Use only original parts Hobart.
W ARNING
The internal electrical system of the RO-I is pow ered by 230 Volts.
Before replace the filter, disconnect the pow er plug.
W ARNING
The enduser MUST NOT disassembly machine draw er from the housing.
DO NOT use cor r osive pr oducts, acids, steel wool or wir e br ushes to clean the device.
DO NOT use low or high pr essur e jets of water when washing the device.
5.1
