● Join or splice the cable ends in a way that causes no additional electrical resistance
in the wires.
● Protect the joint against moisture and oxidation.
2.9 Electrical connections, covers, and cable management
Detaching the front panel (models with an integrated DHW tank)
Unscrew the fastening screws (FS) at the lower edge of the front panel (MFC). Once
the screws have been removed, the panel will hang on the top of the frame by the
flange at its top edge. Lift the panel upward, and pull the panel towards yourself.
Electrical connections
To access the unit’s switchboard, detach the cover on top of the compressor unit
(TC) and the compressor unit front panel (FC). Note that you can make most of the
connections by removing the top cover. Check the electrical connections from the unit’s
electric diagrams.
Switchboard cover and cable entries
Keep the switchboard cover (TC) closed and the screws fastened at all times. Remove
the cover (TC) only when performing electrical installation work.
Keep the cover closed and the screws fastened when filling or bleeding the system’s
circuits (brine circuit, heating circuit, or domestic water circuit). This will prevent leaking
water from entering the compressor unit and spilling over the switchboard. Water can
damage the switchboard.
Thread the cables through the gland plate on the switchboard cover, ensuring that the
glands are properly sealed. Ensure that no leaks or condensate can travel along cables
or through or along insulation onto the switchboard behind the panel.
2.10 Pipe joints
Be careful not to twist or turn the unit’s pipes, especially when making
and disconnecting connections. This could loosen the pipe joints inside
unit.
The pipe joints have 1" inner threads at the ends. Use the supplied flat gaskets to seal
each joint. Equip the pipes with shut-off valves.
Leaks in the brine circuit
Ensure that in case of a brine circuit leak, no water or brine can travel along the pipes
or through or along pipe insulation into the heat pump’s case.
