Advantages of pressurized flow through water heaters “Genie H20”
Instant water heaters Genie H2O 3500, 4000, 4500, 5000, 5500 series are pressure heaters
of power adequately 3.5, 4.0, 4.5, 5.0 and 5.5 kW prepared for 230V power supply.
They are designed for supplying hot water for such receivers as wash basins, sinks,
showers (using original manufacturer’s sprayer set). Heating element structure is designed
for permanent work under water pressure up to 0.65 MPa. Any kind of pressure tap battery
therefore can be fitted to the heater. Connection to the water supply system can be executed
using flexible rubber hoses with rubber gaskets. Small dimensions and easy assembly of
the heaters make possible to perform quick assembly and to hide the appliance under sink
or wash basin.
Traditional mechanical power switching on mechanism has been eliminated in order to
miniaturize and improve reliability of the heater.
1. Application
Pressurized flow through water heater Genie H20 is designed for instant delivery of warm
water to the GreaseShield. In order for economical use of the heater, it should be installed
as close as possible to the GreaseShield.
This appliance is designed to be used in a moist environment. However splashing with water
is prohibited. Maximum delivered water temperature should not exceed 30ºC.
One should remember that heater output depends on:
its electric power;
water stream flowing through the appliance. The bigger flow, the lower water temperature
on exit (table 1);
voltage drop in electrical system. For instance: voltage drop by 10% results in lowering
heating output by 19% (table 2). Voltage drop below 185V causes blockage by electronic

Heater must not be installed in rooms where temperature drops below 0ºC.
Heater should not be installed in aggressive or subject of explosion environment.
Heater can only be used when is in perfect technical condition.
In case of heater’s defect immediately cut off water and power supply.
All service and maintenance works can be completed only with power switched off

Only original spare parts can be used for repair
Casing should never be disassembled while power is on
Avoid electronic system to be splashed with water
In case of heater’s defect or improper work switch off power and shut off water supply
using stopping – suppressing valve.
Water tap drain tube sprinkler (strainer) should be cleaned regularly.
Power supply system should be periodically checked up (voltage drops), particularly
electrical connections.
Water flow should be suppressed in such way to avoid excessive temperature (take
care of children).
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a
person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
3. Wiring system
The heater can only be used previously connected to earthing system.
Wiring system should be equipped with differential switch.
Minimum wire cross section and fuse value should be selected according to table 3.
Before heater’s installation check state of wiring system and particularly terminal.
After heater’s connection to wiring system measure voltage drop under load

4. Assembly
CAUTION!
The device can only work in position showed on drawing No 1.
Heater installation in position other than proper one or without water
filter can damage heating element and cause the guarantee to be null
and void.
Do not screw connecting hoses with high power in order to avoid threads
damage.
Do not overtighten hose connections.
Do not seal stub pipe thread with PTFE tape or Teflon
TM
sealing tape.
Protect electronic system against water splashing.
1. Apply pattern on place the heater will be installed. Mark places for drilling holes for
anchoring pegs and cable. Cable can be connected to the heater in two ways as
presented on drawings 3 and 4.
2. Screw heater on.
3. Connect heater in a way showed on fig. 6. Remember to fit water filter as showed on
fig. 5. Use flexible hoses designed for pressurized system with rubber gaskets. Do not
exchange heater outlet (red colour) with intake (blue colour).
4. Open water valve and check all connections tightness. In case electronic system is
splashed with water, remove it by blowing with compressed air.
5. Open full water flow through the heater in order to deaerate heating element.
6. Connect heater to the power installation.
7. Change sprinkler (strainer) mounted on drain pipe for the one delivered by heater
manufacturer.
8. Adjust heater according to chapter 6.
9. Remember to clean strainer periodically.

6. Heater On Demand Installation
1. Switch OFF the Water Supply .
2. Electrically connect the HOD unit but DO NOT switch ON
3. Connect the supplied HOD INLET (BLUE) to the COLD water supply using a suitable
1/2” x ¾” flexible pipe approved to local standards.
4. Connect the OUTPUT(RED) of the HOD Unit to the Water Solenoid INPUT of the GS
( GreaseShield Low Level Unit ) using a suitable 1/2” x ¾” flexible pipe approved to local
standards..
5. Switch ON the water supply to the HOD and then Switch ON the GS-LL.
6. Allow the water to flow through the HOD for 30 seconds to prime the system
5. Operating Principal
In addition to the NORMAL inlet, The GS-LL incorporates a Low level tank to which the
outlet from a 20 grid floor level oven is connected. The low level tank includes a bypass
outlet to the normal drain as a backup overflow system should the GS-LL malfunction.
The tank also includes a final baffle so that should bypass occur grease will not be pas-
sed to drain.
The GS-LL also includes a normal level inlet which facilitates a 10 grid oven to be con-
nected as normal to the main tank within the GS.
Thus a 20 grid and a 10 grid oven can be accommodated in the one GS –XX-GS-LL unit.
Installation Steps:
The unit comes complete with a
“Heater On Demand”
HOD water heater unit which is
plumbed into the COLD water supply and preheats the intake water to condition the Low
level tank within the GS-LL prior to the days cooking.
It also provides a top up periodically to the tank to ensure correct operation of the GS.
The heater on demand system MUST have through flow rate of approximately 2 litres /
minute.
This flow rate is achieved by a flow controller which is placed on the OUTLET (RED) side
of the HOD module (already attached).
Please follow HOD manufacturer’s instructions and recommendations when electrically
connecting the HOD to the Electrical supply.
Only Electrically Qualified Personnel in accordance with local rules should electrically
connect the HOD.
The Heater on Demand Unit (HOD) must be secured to a suitable surface near the GS
unit clear of any other pipes from other kitchen equipment.

7. Adjustment
Caution!
When used in conjunction with the flow regulator on the HOD output (
red
) no
external flow regulation is necessary.
Water temperature at the HOD outlet should be in the range of 40 to 50 degrees
centigrade (but may vary in some situations).
7. Switch on the HOD unit at the main socket.
8. Undo the access cover on the GS and press and hold button “B” for 10 seconds. This
will open the water solenoid for 5 minutes and allow water to enter the LL tank. This in
course will then be pumped up to the main tank .Repeat as necessary to fill the Main
Tank of the GS.
9. Check the water temperature entering the main tank. It should be warm to the touch.
10. When water flows over the outlet weir of the main tank outlet the unit is charged and
ready for use.
11. Replace the end Cover.

8. Water filter cleaning
1. Turn off water inflow by shutting off valve and disconnect from power line.
2. Disconnect hose from heater intake.
3. Take out filter (using small screw driver – see fig. 8).
4. Remove dirt from filter.
Caution! Do not screw
up hoses nuts too
tightly in order to
avoid heater’s pipes
thread damage.
