Section 8: Electrical Connection
Routing of cables within the heat pump

To avoid the electrical cables becoming
damaged by sharp edges they must exit
through the bushing located at the right side of
the heat pump.

The cables must be secured using the clamp
on the control board.
Ducting cables
To access the electrical connections only the front right
hand panel of the heat pump outer casing needs to be
removed as shown in
Error! Reference source not
found. .
Depending upon the installation the heat pump could
have the following cables that it will be necessary to
route from the heat pump into the property.
1. Main power supply cable
2. Heat pump controller
3. Communication cable for 2 way valves, high
limit stat etc, room thermostat.
4. Domestic hot water sensor
5. Domestic hot water immersion heater (booster
heater)
Ducting should be used to ensure that the enclosed
cables are protected from the effects of weather,
mechanical snagging or wear, rodent damage ect. The
ducting should be positioned in such away to ensure
that water will not track along the ducting and into the
heat pump or property.

For typical wiring and hydraulic
schematics see section 16 at the end of
this document.
When connecting the heat pump to
the power supply, the relevant EN
standards must be complied with.
Any further connection requirements
stipulated by local utility companies
must also be observed. It is important
that the hydraulic connections have
been completed prior to switching on
the power supply.
