• 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.
