Installation instructions

Hydraulic connection

The pool components must be put into place according
filtering pump > filter > heat
to the following sequence:
pump > water treatment device > water pool return.
If an automatic chlorine distributor or electrolyser is used, it must be installed
in the water pool return pipes after the heat pump with the aim of protecting
it from concentrated chemical products. It is preferable to use rigid PVC
pipes.
All of the pipe nozzles must be attached with PVC glue. When the hydraulic
installation is complete (respect the glue sticking time), start the heat pump
and check the system to see if there are any leaks. Then make sure that the
filter pressure is normal.
Note: Some installations use a "By-pass" system enabling the water to circulate only in the base
circuit of the pool without going through the heat pump. If the water circulation has stopped in the
heat pump for a few days, make sure the condensor is drained.

Electrical connection

WARNING
Your electrical installation must be carried out professionally by a
registered qualified electrician and complying with the standards in force
(p30)
Single-phase Supply: 230V - 50Hz - 1 phase

Three-phase Supply: 400V - 50Hz - 3 phases

Make sure that you switch off the power supply before proceeding with in-
stallation and maintenance of the heat pump and its electrical elements.
All the electrical wires of the heat pump must satisfy the electrical standards
in force especially as regards the earth connection.
The circuit must be installed by an registered qualified electrician.
With any electrical connection, ensure that the supply voltage, the live wire
number and the electrical power of the unit match those of the installation
location.
The electrical supply of the heat pump must be protected by a leak circuit-
breaker with 30mA earth curve D without sharing the supply with any other
device.
Check that the voltage and supply frequency correspond to those indicated
on the heat pump.
