3. INSTALLATION OF THE UNIT
The heater shall be be placed in a technical equipment area (ventilated, dry and without stored pool
maintenance substances), close to the filter of the pool. It shall be fixed to the wall by means of 4 screws
(see points of fixing on back sight §2.2).
4. CONNECTIONS
4.1 Hydraulic connections
The electric heater shall be connected in line to the return circuit downstream the filtration process, with
a minimum flow rate of 5m³/h up to 22m³/h. Plan for a by-pass fitting if the filter is above 22 m³/h or to
facilitate the maintenance of the appliance.
1/2 unions (Ø50 female inside and Ø63 male outside) are designed to make a connection with the
filtering circuit with a Ø50 or Ø63 PVC pipe.
Warning:with a Ø63 pool circuit, to connect the device, provide a sleeve (Ø63 inside).
Advised fitting: if possible, the heater connection should be carried out so that it is on load as
compared with the filtration system or the pool.
Direction of circulation: the heater is arranged for water circulation from left to right. If necessary,
reverse the direction of circulation by making the following changes:
- reverse the digital regulation thermostat and safety thermostat sensors. The regulation thermostat
sensor must be at the heater input and the safety sensor at the output.
- turn the 2 elbows + flow switch unit by half a turn:
- Test pressure: 4 bars - Service pressure: 2 bars
The heater shall be installed before any water treatment system.

4.2 Electric connections
• the electrical supply of the heater must come from a protection and switching device (not supplied)
complying with the standards and regulations in force in the country where it is installed (in France,
refer to standard NF C 15100). The RE/U from 3 to 9 kW may be supplied by single-phase
(230V/1N/50Hz) see figure 1, or in three-phase (400V/3N/50Hz), see figure 2. The 21 and 24 kW
RE/U must be supplied with three-phase current (400V/3N/50Hz).
• supply cable section: this section is recommended for cables of a maximum length of 20 metres,
with a calculation base of 5A/mm². It must be checked and adapted if necessary, depending on

5. USE OF THE CONTROL DISPLAY
5.1 Presentation
The digital regulation thermostat is supplied installed on the heater, including its electrical connections,
and is factory preset for a swimming pool heating application.
Principle: a regulation sensor placed at the point where the water enters the swimming pool from the
heater measures the pool temperature (with the filtration system running), and compares this value with
the set temperature. If the temperature of the pool drops or is below the set temperature, the thermostat
switches the heating on (power to the primary heating circuit circulation pump). The "REG" indicator
flashes then stays on.
1. digital display to see both the pool water temperature and the set temperature,
2. “SET”: key to read or change the set temperature
3. : touch sensitive button to increase the set temperature
4. : touch sensitive button to reduce the set temperature (or switch off the “beep” sound indicating a fault)
5. “REG”: regulation indicator: on = digital thermostat in “on demand” mode or flashing = activation of the time
delay before primary heating circuit pump switched on
6. “S1”: switch “on/off” for the 1st heating stage (+indicator)
7. “S2”: switch “on/off” for the 2nd heating stage (+indicator)
8. thermostat fuse housing
9. electrical connectors
5.2 Setting the required temperature
Press the “SET” key to display the set temperature, then keep it pressed and press the key to
increase it or the key to reduce it. Then release the “SET” key in order to return to the pool
temperature display.

• each electric resistance has a manufacturer’s tolerance of ±5% concerning its power restitution,
• appliance protection index: IP 45
6.1 Operating conditions
The temperature of the water circulating in the heater must be between 2°C and 40°C.
Before switching the device on, you need to make sure:
• the hydraulic fittings are correctly tightened,
• there is no leak,
• the appliance is correctly fixed to the wall,
• the connections of the electric cables are correctly tightened,
Incorrectly tightened cables may cause overheating of terminals,
• the appliance is correctly connected to the Earth,
• the water contained in the appliance is not frozen,
In this case, it is interdict to put the heater under operation.
6.2 Starting up
• run manually the filtering pump for an operational test of the heater and at the time of the first rise in
temperature in the pool (once the pool is at the right temperature, put the filtering back on automatic),
• purge the air from circuit and make sure no air remains in the appliance,
• check the flow rate is between 5 and 22 m³/h,
• switch on the mains supply circuit breaker,
if the flow rate is higher than 22m³/h per hour, fit by by-pass,
• switch on the 30 mA différentiel circuit breaker, at the head of the line,
• Adjust the digital thermostat temperature to be “on demand” (“REG” indicator flashing),
• press the key(s) “on/off” (“S1” and/or “S2”),
If the heater has been switched on for over 15 seconds, engaging one or more of the heating stages will
be simultaneous (“REG” indicator on). If not a time delay will be active (“REG” indicator flashing), before
indicator is “on” heating operation (stage 1 and/or 2 engaged).
Warning:
•if the water flow in the heater is less than 5 m³/h the heater will not work (flow controller “CD”
remains open). If the device is “on demand” with regard to heat the “REG” indicator will flash.
When the heater is operating:
•if the flow controller opens then closes, there will be a 15 second time delay before restarting.
•if there is a failure of the mains power supply, when it comes back on again there will be a 15
second time delay before restarting.
Observation: when the pool reaches the desired temperature, the “REG” indicator goes out, and the heater stops
heating.
6.3 Checking
Make sure that the heater stops when:
• decreasing the required temperature on the control thermostat,
• filtration is switched off or a valve is closed,
• when pressing key “S1” and/or “S2”.
Important! Before any intervention, make sure the unit is switched off.

6.4 Failure
In the event of abnormal heating, the heater stops automatically by the positive overheating safety
thermostat (TS) placed at the top of the appliance: re-arm by pressing the central button of this
thermostat.
In case of a visual and sound defect on the regulator (in order to stop the "beep" sound press the
key):
•if “E0” is displayed (flash and beep):
- regulation sensor is not working (cut or short-circuited or disconnected).
- reconnect or replace the sensor.
- the defect display corrects itself automatically.
•if “E2” is displayed (flash and beep):
- the regulator is not working (damaged electronics).
- replace the digital display regulator.
If the regulator display does not work, check that:
•the mains supply is live,
•the regulator protection fuse is not blown
6.5 Winter storage
• presse keys “S1” and “S2” to stop the heating stages,
• switch off the power supply (by disengaging of the 30 mA differential circuit breaker at the head of
the heater line),
• drain the heater by removing the stopper located at the low point of the injected body (see part 7
§2.1) and unscrew the fittings (risk of frost),
The guarantee will be cancelled in event of frost of the appliance due to an improper
winter storage.
6.6 Restart
•refer to the procedures described in paragraphs 6.1, 6.2, 6.3 and 6.7.
6.7 Maintenance
To be done once a year by an approved and qualified person:
•visual check of the condition of the various electrical components,
•retighten cables and supply terminal board shunts and the switch,
•Check the state of titanium electric resistance:
- If it's scaled, make a chemical cleaning while plunging it in a 10% acid solution,
- If it's damaged (bluish or deformation), replace it.
7. PRECAUTIONS
ATTENTION!
Make sure the appliance is disconnected from mains supply before any intervention. Any
intervention shall be qualified and authorised personnel only.
