5.6 Electrical Connection
NOTE: Only a suitably qualified and competent electrician should
electrically connect this unit.
1. The acceptable voltage variation is ±10% during operation.
Do not carry out an insulation test on this unit. The insulation test should only be carried out on the
cabling in the system.
5.7 Cable size
NOTE: Please calculate the correct cable size for this installation, failure to do this could lead to a FIRE
RISK or a waste of materials and associated costs.
1. After designing circuits it is necessary to check compliance with the requirements of part 4 BS 7671
and the limitations are achieved.
2. The electrical connection conduits must be fixed and supported in accordance with local regulations.
3. Use the cable clamps at the rear of the unit and route the wires under the electric panel at the level of
the terminal strips. Use the cable support supplied for incoming cable below power connection point.
4. The electrical installation must comply with the standards and regulations applicable where the unit is
being installed.
5. Baxi recommend the use of rodent proof cable or conduit for all externally routed wiring.
Example: The Baxi Ambiflo
™
heat pump is 20m from the consumer unit, the cable is mounted enclosed
in a thermal wall, the calculations point to a 10 mm
2
cable to support the air sourced heat pump. If this is
mounted on a wall etc# the calculations will allow an 8 mm
2
cable.
5.8 Power Supply
1. The power supply must come from an isolation and electric protection device (not supplied) in
accordance with existing regulations.
