4.1 Electrical Information
The electrical connection of the unit must be carried out by a qualified
electrician.
The unit is supplied with a pre-wired power supply. This power supply
unit has a metal bracket incorporating fixing holes, which should be
used to fit the power supply to a suitable surface e.g. a wooden joist.
The fan unit is also supplied with a fused spur. The two core mains
cable from the power supply should be connected to a fixed wiring
installation, via the spur, in accordance with current IEE wiring
regulations.
Disconnection from mains must be incorporated within the fixed wiring
and shall have a maximum contact separation of 3mm in accordance
with latest edition of the wiring regulations.
For good EMC engineering practice, the KWH150-ECO-LC power
supply output cable and any sensor cables should not be placed
within 50mm of other cables or each other.

3.4 Fan Unit Installation
3.4.1 Joist Hung (Standard Mounting)
The standard method of installation is to suspend from a convenient
roof beam via the cord supplied (unit weight = 3.5 kg). The method of
locating the cord to the roof timber is the responsibility of the installer.
The flexible duct (maximum length 2m) is connected to the fan unit
by inserting the duct over the fan outlet and held in place using the
supplied cable tie. This method is repeated when connecting the duct to
the ceiling vent. Ensure all duct joints are airtight.
The flexible ducting should NOT be installed in a compressive
state, as this will negatively impact on the performance of the unit.

3.4.2 AV Mounting (Alternative Mounting)
The AV kit contains all the parts necessary to complete a joist mounted
installation. If AV mounting is required the kit can be purchased direct
from Kair using the following code number: 771393.
Lower the unit with battens (battens not supplied by Kair) attached
onto the joists. Mark and drill the 12mm Ø clearance holes required in
the ends of the battens.
Place anti-vibration mounts above and below each batten fixing point
and, using the 4 large screws and special washers, fix the unit to the
joists.
Do not overtighten the fixings. The distance from the top washer to
the joist when installed must not be less than 50mm.
