Selecting the most suitable installation position
Indoor Unit
z
Ensure there is no heating or steam source nearby.
z
No obstacles are in the way of the pipes or wiring.
z
There is good air circulation all round.
z
It is convenient to adopt measures to reduce noises.
z
Don’t install them near the doorway.
z
Make sure you have the distance specified in the picture between
the ceiling, walls, furniture and other obstacles.
z
Install 2 metres high above the floor (for best performance).
z
The system can be fitted at the top of a dwarf wall, but you will lose
some efficiency. The front vents must not be obscured by furniture
etc. If in doubt you should opt for the next size system up when
fitting to a dwarf wall.
z
The picture to the right shows just one possible option for routing of
the pipes/wires from the indoor unit to the outdoor unit. Although,
you can exit the copper pipes at the left hand or right hand ends, or
from the bottom of the indoor unit, as well as at ninety degrees
straight through the wall to the rear of the unit. You will find there
are ‘cut-out sections in the plastic, which can be removed to
accommodate the pipes exiting from different positions.
z
The 2 copper pipes attached to the rear of the indoor unit are
designed to be ‘swivelled’ through 90 or 180 degrees to give these
other positioning options, but care must be taken not to kink or
crush the pipes. You need to hold them at the point where they are
attached to the back of the indoor unit, then gently move them in
small stages of 2cm at a time with a 3 second rest between each. It is also recommended that the
foam insulation be cut carefully with a knife and rolled back at the point of swivel so that you can
see the copper pipes and make certain that you are not compressing them or kinking them during
this pipe alignment process. Once finished, the foam insulation should be put back and re-taped
in place with a good quality waterproof tape.
Outdoor Unit
z
The outdoor unit can be positioned higher or lower than the indoor unit.
z
The unit is designed to be weather-proof; however, ideally the unit should be sited in the shade to
avoid the heat of the midday sun as this can affect cooling performance. You can shade with a
‘porch’ type canopy if you wish. If you put up a canopy to protect it from rain and sun, pay attention
not to cause any obstruction to the dissipation of heat from the condenser.
z
There must be at least 100mm of space to the rear and sides and 600mm to the front of the
outdoor unit. Make sure any excess copper pipe-work that may be ‘coiled’ up behind the
condenser is not obstructing it from drawing air through the rear of the unit.
z
Don’t keep animals or plants near the installation location as the hot air from the outdoor unit will
affect them. Also do not allow any foliage to grow into the unit, check it often to ensure it is free
from all obstructions.
z
In the wintertime, check that the large fan can rotate freely and that it is not blocked with leaves,
snow or ice.
z
Make sure you have the distances specified above between walls and other obstacles.
z
Keep away from heat sources or flammable gases.
z
The installation base and supporting frame should be strong and secure. The machine should be
on a horizontally level surface.
z
You can obtain a wall bracket mounting kit from your reseller, or directly from us.
z
If you are mounting the unit on a flat roof it is recommended that you fix it to 2 external grade
timbers of 100mm x 50mm x 1000mm, like ‘skis’ so that it cannot blow over in high winds. It is
recommended to use countersunk galvanised bolts fitted from underneath so as not to damage
any felt roof. Then secure on top of the outdoor unit’s ‘feet’ with nylock nuts. Check the installation
periodically to ensure it is stable and secure.
