replaced without difficulty.
10. The maximum distance between the standard
indoor unit and outdoor unit is 4 m. The
maximum possible length of the refrigerant line is
10 m with a maximum height difference of 5 m.
11. Avoid direct sunlight.
Outdoor device
1. Select a location which avoids causing a
nuisance to neighbours from noise and air
emissions from device.
2. Select a location which is sufficiently well
ventilated.
3. Never cover the air inlets and outlets.
4. The location must be sufficiently firm for
installation and the prevention of vibrations.
5. There must be no risk presented by combustible
gas or gas escaping as a result of corrosion.
6. Check that the device is installed in accordance
with regulations.
7. It should be installed at least 20 cm above the
expected snow line. Snow must not be allowed
to get into the outdoor unit.
8. The wall for installation must be strong and
capable of supporting the weight of the unit.
9. The device must not be exposed to strong gusts
of wind.
10. Make sure that the device is well ventilated and
kept free of dust. Avoid direct exposure to rain
and sunlight.
11. Install on a firm base, avoiding excessive noise
or vibrations.
Important:
The following could cause malfunctions.
Check with your service company in order to
prevent possible malfunctions at a later date.
The following locations should be avoided for
installation:
앬 A location where oil (machine oil) is stored.
앬 A location where there is a high salt content.
앬 A location with numerous sulphurous sources,
e.g. spa zones.
앬 A location where radio transmitters or amplifier
aerials, welding equipment or medical equipment
are in use.
앬 A location where the outdoor device is exposed
to direct sunlight. If necessary the device must
be protected with a sun-shade. Such a sun-
shade must not interfere with the air flow,
however.
앬 A location in the vicinity of heat or steam
generators.
앬 A location which is heavily exposed to dust.
앬 A location to which the general public have
access.
앬 A location with any other unusual characteristics.
Important!
앬 The direction in which the air is blown should
correspond with the prevailing direction of the
wind.
앬 Never install in locations exposed to aggressive
air.
앬 Comply with all specified minimum distances
(see Important notes on installation).
앬 The indoor and outdoor devices may only be
installed if they are in a horizontal position
measured using a spirit level. Check this after
you have completed the installation work.
앬 Do not kink or compressed the refrigerant lines.
앬 All the refrigerant lines, including connectors and
valves must be fitted with diffusion-resistant heat
insulation.
앬 Do not remove the protective caps from the
refrigerant lines / connections on the device until
immediately before you connect them.
앬 Open refrigerant lines must be protected from
the ingress of moisture by suitable caps or
adhesive tapes.
B. Installing the indoor device
It is imperative that you comply with the installation
instructions.
1. Before you start installation
앬 Select the location for the indoor device (follow
the previous notes on selecting the location for
installation).
앬 Check that the available mains voltage is the
same as the voltage specified on the rating plate.
앬 Fit appropriate insulation, supplied by the
customer, to the coolant tubes.
2. Fitting the mounting plate (Fig. 15/16)
앬 The mounting plate for the indoor device must be
fitted horizontally to the wall. In doing so, it is
imperative that you comply with all specified
distances. Mark and drill the holes for fastening
the mounting plate, and then firmly fasten with
dowels and screws. In order to prevent vibrations
on the indoor device, make sure that there are
no gaps between the wall and the mounting
plate.
3. Drilling holes through the walls (Fig. 16/17)
앬 Drill the hole through the wall for the lines/hoses
using a 90 mm drill bit, drilling from the inside (A)
to the outside (B) at an angle downwards of
