Installation of the Indoor Unit
PLEASE NOTE: when removing the
first
copper
end plug pipe (either one, as it does not matter
which is removed first) from the back of the
indoor unit (these are the short pieces of pipe
with crimped and soldered ends, or end caps)
you should hear a rush of air escaping at high
pressure, this is completely normal, the units are
pressurised at the factory to ensure it is leak free
when you receive it. If you do not hear any air
escape as the first of these pipes are undone,
please contact us BEFORE FITTING as your unit
may
be faulty.
Installation Procedure
z
First check the wall and make sure that it is firm and secure. Use four suitable screws with
suitable wall plugs to fasten the installation bracket onto the wall. Keep it level and completely flat
to the wall otherwise it might cause water droplets to form on the plate when the air-conditioner is
running in cooling mode. Make sure the top is well fixed at the highest points, or the bracket may
flex.
z
Decide where you are going to position your pipe-work for exiting through the wall.
z
See ‘selection of the installation position’ in section 1 above for notes on different ways to position
the copper pipes.
z
The water drain pipe attached to the back of the indoor unit may be positioned at either end of the
drip tray. There is a rubber ‘bung’ at the opposite end. Simply remove the ‘bung’ and swap it with
the water drain pipe. Make sure that both a re-fitted securely so the do not leak any water. Use
some PTFE plumbers tape if required to form a tight seal.
z
Drill a 65mm diameter hole where you are going to exit your pipe-work through the wall of the
building.
Alternatively
(if you have visible bricks on your building) remove a quarter of a brick by
‘chain’ drilling a series of small holes joined together vertically down through a brick, then drill the
same round the end of the mortar and knock through the quarter piece of brick. The hole should
slant downward slightly so that your water drain pipe will have a sufficient ‘run-off’ to use gravity to
drain the condensate water from the indoor unit to the outside of the building. (The indoor unit can
produce over 2 litres per hour in the summer). There is a 2 metre ribbed extension pipe which
may be used if necessary to extend the condensate drain pipe, please use a good tape to join the
2 pipes. The extension fits on one way round only.
z
Once you have decided where you will be placing your copper pipes, water drain pipe and
electrical wires, and drilled the suitable holes for each (or combined all together into 1 hole), you
are ready to mount the indoor unit. Depending on your pipe directions you may need to attach
your copper pipes to the pipes on the back of the indoor unit first (refer to the section on attaching
pipes if necessary).
z
‘Hang’ the indoor unit on the 2 ‘lugs’ at the top of the mounting bracket and make sure the unit is in
the middle of the bracket. Push the lower part of the casing against the mounting bracket until the
2 bottom ‘latches’ on the mounting plate click into place
on the rear of the plastic casing.

Checking the water discharge
Only attempt this procedure if you are confident you
will be able to remove/replace the front plastic casing without
damaging the clips at the top of the unit. If you have fitted the
water drain pipe correctly, slightly downwards then it will
most likely be OK anyway!
