6.10 Draining the Condensate
The condensates tube should not be directly
connected to a drain. It must terminate into open air
through a U-bend which has been added and contains
water.
- Do not use an elbow on the flexible hose
Figure 14: Detailing the correct connection of
condensate draining
6.11 Electrical Connections
The power supply should comply with the regulations in
the country of installation, as well as the IEE Wiring Reg-
ulations.
A means of disconnection which ensures an electrical
isolation in Category III conditions should be installed
in fixed cabling in compliance with the installation rules.
Protect the appliance with :
- A 13A fused spur or isolator must be installed adjacent
to the appliance for mains supply connection.
-A 16A RCBO type C circuit breaker must be fitted at
the local consumer unit on the same supply.
If the power supply cable is damaged it must be
replaced by a suitably qualified technician or electrician.
6.11.1 Accessing Electrical Connections
To access electrical connections:
- Isolate the electrical connections.
- Remove the cover from the top of the appliance by
taking out the screws which fix the lid onto the lower
base of the heater.
- Remove the black protective cover from the electronic
board.
Only a voltage-free, external connection may be
used, or the electronics board may be destroyed.
6.11.2 Electricity Provider Contact
To stop the electrical back-up immersion running during
peak time, connect the voltage-free contact from your
electricity meter to terminal n°1, please refer to Figure
15.
- Contact open
- Contact closed = electrical back-up authorised
If you choose load shedding level 1, the electrical
back-up is prevented from running. If you choose load
shedding level 0, both the electrical back-up and the
heat pump will be prevented from running (see Section
7.11.6).
To prevent electrical backup operating during peak
hours, if a volt free output is not available from the
meter, a timer switch should be used if:
- Switch off = backup not allowed
- Switch on = backup allowed
Only a zero-voltage, external control such as a timer
switch should be used (if not, the electronic board could
be destroyed).
- Pass a 0.75mm 2-wire cable with crimped ends
through a cable gland at the back of the appliance
and bring the end of the cable round to the electronic
board. The other end of the cable should be
connected to the timer switch.
- Insert the 2-wire cable through a grommet on the
electronics board.
- Connect the 2-wire cable to "Entrée 1" indicated on
the electronic board, having removed the existing red
bridge beforehand.
