Starting Up; Checking; Failure; Winter Storage - Zodiac PSA Heat line Plus 20 kW Notice D'installation Et D'utilisation

• 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 ground,
Note: after a long stop, check if the circulation pump is not blocked, in this case, before switching on, undo the
screw in the front of the circulator (warning!
screwdriver.

6.2 Starting up

• start the filtration pump,
• Check the pool water circulation in the exchanger,
• Check the filling and degassing of the heating circuit,
• switch on the 30 mA différentiel circuit breaker, at the head of the line,
• set the required temperature on the display to be on demand ("reg" light flashing) see§ 5.2,
• press key ,
With a demand for heating and the filtering in operation, the "reg" led flashes for 15 seconds, then stays
on. The internal regulator contact (terminals 19-20) is then closed => heating in progress (the circulator
must be in operation).
N.B.: energy is transferred to the secondary circuit to give calories to the pool.
Observation:
- when the appliance heats the water ("reg" led lit up), if the filter stops or if the water flow rate is less than 5
m³/h, the appliance stops heating ("reg" led flashing). The flow controller "CD" is open,
- when the pool reaches the desired temperature, the appliance stops heating ("reg" led off).

6.3 Checking

Make sure that the heat exchanger stops when:
• decreasing the required temperature on the control thermostat,
• filtration is switched off,
• when pressing key
Important! Before any intervention, make sure the unit is switched off.

6.4 Failure

• if the regulation probe is out of service or disconnected, with a flashing "E0" displayed, appliance
switched off and disabled, reconnect or change the probe.
• If the regulator display does not work, check that:
1) the mains supply is live,
2) the regulator protection fuse is not blown (see paragraph 5.3)
• if the pool water temperature rises beyond the setpoint temperature, check that:
1) the regulator is working properly,
2) no other circulator is pushing on the primary circuit. If this is so, plan for a solenoid valve at the
outgoing direction of the primary heating circuit controlled by terminals 19-20.

6.5 Winter storage

• switch off the appliance by pressing key
• switch off the power supply (by disengaging of the 30 mA differential circuit breaker at the head of
the exchanger line),
• drain the pool circuit by removing both connection union fittings in order to avoid the risk of frost.
• drain the primary circuit by removing the drain plug if frost can be expected.
The guarantee will be cancelled in event of frost of the appliance due to an improper

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.
