Water Pipe Insulation; Wiring On Field - Immergas MAGIS M4-30 Use And Installation

NOTE
It might not be possible to remove all the air in the system while filling. The remaining air will be removed by means
of the automatic air purge valves during the initial hours of operation of the system. It could be necessary to top up
water afterwards.
• The water pressure varies depending on the water temperature (the higher the temperature the higher the pressure).
Nonetheless, water pressure must always remain below 0.3 bar to prevent air from entering the circuit.
• The unit might discharge too much water through the safety valve.
• The quality of the water must comply with directives EN 98/83 EC.
• Details on the water quality conditions are found in directives EN 98/83 EC.

9.6 WATER PIPE INSULATION.

The entire water circuit, including all of water pipes, must be insulated to prevent condensate from forming in cooling mode
and the reduction of heating and cooling capacity, as well as to prevent the outside water pipes from freezing during winter.
The insulation material must have a fire resistance of at least B1 and must comply with all standards in force. The sealing
materials must be at least 13 mm thick with thermal conductivity 0.039 W/mK to prevent outside water pipes from freezing.
If the outdoor temperature is above 30° C and 80% RH respectively, the thickness of the sealing materials shall be at least
20 mm to prevent any condensate build-up on the gasket surface.

9.7 WIRING ON FIELD.

WARNING
A main switch or another disconnection device, with separation of contacts in all poles, must be incorporated in the
fixed wiring in compliance with local laws and standards. Switch of power before performing any connection. Only use
copper cables. Never clamp the cables in bundles and make sure they do not come into contact with pipes and sharp
corners. Make sure no external pressure is applied to the connections of the terminals. All the cables and components
on the field must be installed by an authorised electrician and must comply with local laws and standards.
On-field wiring must be carried out according to the wiring diagram supplied with the unit and in compliance with
the following instructions.
Make sure to use a dedicated power supply. Never use a power supply shared by another device.
Check that there is an earthing connection. Do not earth the unit to a service pipe, to a surge protective device or to
earthing of the telephone line. Incomplete earthing can cause electric shocks.
Make sure to install a ground fault circuit interrupter (30 mA). Otherwise electrical shocks could occur.
Make sure to install the required fuses or circuit breakers.
9.7.1 Precautions for wiring jobs.
• Secure the cables so that they do not come into contact with the pipes (especially on the high-pressure side).
• Secure the wiring with cable clamps to prevent them from coming into contact with the pipes, especially on the high-
pressure side.
• Make sure no external pressure is applied to the connectors of the terminals.
• When the ground fault circuit interrupter is installed, make sure that it is compatible with the inverter (resistant to high-
frequency electric disturbances) to avoid needless opening of the round fault circuit interrupter.
NOTE
The earth leakage circuit breaker must be a high-speed switch of 30 mA (<0.1 s).
• This unit is fitted with an inverter. The installation of a shunt capacitor not only reduces the improvement effect of the
power factor, but can all also cause anomalous heating of the capacitor due to high-frequency waves. Never install a shunt
capacitor as it could cause accidents.
