Installation of Outdoor Unit
The outdoor unit of is installed outside to exchange heat with ambient air. Therefore, it
is important to secure proper space around the outdoor unit and care for specific external conditions.
This chapter presents a guide to install the outdoor unit, make a route to connect with the indoor, and
what to do when installed around seaside.
• If a sunroof is built over the unit to prevent direct sunlight or rain exposure, make sure that heat ra-
diation from the heat exchanger is not restricted.
• Ensure that the spaces indicated by arrows around front, back and side of the unit.
• Do not place animals and plants in the path of the warm air.
• Take the weight of the outdoor unit into account and select a place where noise and vibration are
minimum.
• Select a place so that the warm air and noise from the outdoor unit do not disturb neighbors.

For controlling the heating according to the external temperature, it is necessary to install the exter-
nal temperature sensor.
The sensor must be set up in a shady spot.
The sensor must not be set up above a window or door. It must be located away from heat
sources.
For measuring external temperature, the sensor type PT 1000 is used.

Seasonal wind and cautions in winter
• Sufficient measures are required in a snow area or severe cold area in winter so that product can be operated well.
• Get ready for seasonal wind or snow in winter even in other areas.
• Install a suction and discharge duct not to let in snow or rain.
• Install the outdoor unit not to come in contact with snow directly. If snow piles up and freezes on the air suction hole,
the system may malfunction. If it is installed at snowy area, attach the hood to the system.
• Install the outdoor unit at the higher installation console by 500 mm than the average snowfall (annual average snowfall)
if it is installed at the area with much snowfall.
•
Where snow accumulated on the upper part of the Outdoor Unit by more than 100 mm, always remove snow for operation.
1. The height of H frame must be more than 2 times the snowfall and its width shall not exceed the width of the
product. (If width of the frame is wider than that of the product, snow may accumulate)
2. Don't install the suction hole and discharge hole of the Outdoor Unit facing the seasonal wind.
Installation at Seaside
1. Air conditioners should not be installed in areas where corrosive gases, such as acid or alkaline gas, are produced.
2. Do not install the product where it could be exposed to sea wind (salty wind) directly. It can result corrosion
on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunc-
tion or inefficient performance.
3. If outdoor unit is installed close to the seaside, it should avoid direct exposure to the sea wind. Otherwise it
needs additional anticorrosion treatment on the heat exchanger.
Periodic ( more than once/year ) cleaning of the dust or salt particles stuck on the heat exchanger by using water
Selecting the location(Outdoor Unit)
1) If the outdoor unit is to be installed close to the seaside, direct exposure to the sea wind should be avoided.
Install the outdoor unit on the opposite side of the sea wind direction.
2) In case, to install the outdoor unit on the seaside, set up a windbreak not to be exposed to the sea wind.
3) Select a well-drained place.
• It should be strong enough like concrete to prevent
the sea wind from the sea.
• The height and width should be more than 150% of
the outdoor unit.
• It should be keep more than 700 mm of space
between outdoor unit and the windbreak for easy
air flow.

Installation of Indoor Unit
• It is obligatory to consider the minimal clearance from obstacles for ensuring unobstructed access
for maintenance and service.
• The location of the device has to be accessible with manual transport devices to ensure undis-
turbed delivery of replacement parts and equipment for maintenance and servicing. The operator
is charged costs connected with hiring special equipment for installing the device, servicing and
maintenance separately, these costs are not subject of the warranty.
• When you install the device into the building, make sure that you build in a water drain which will
serve as a water drain in case of spillage.
Minimal clearance from the device
The device must not be installed under pipelines because there is a possibility of condensate form-
ing. Ingress of water condensate can cause disturbances in the operation.
The installation location of the indoor unit must be dry and in the temperature range between +10
C and 40 °C.

Front panel removal
Front panel removal
The connection between the indoor and outdoor unit is performed via refrigerant pipes and communi-
cation line.
The pipeline and electrical cables have to be protected with heat and waterproof insulation in a
protective pipe. This prevents the pipe connections soaking in cases of high groundwater or rain-
water and with it intensive draining of heat into its surroundings.
Gas and liquid connection
The pipe connection between the external and internal device can be made by laying the pipes in
two ways:
• A inside two separate ribbed protective pipes,
• B in one joint ribbed protective pipe.
Connection with the outdoor unit
First unscrew 2 screws of panel (A). Open the panel (A) towards yourself and pull up-
ward. After this repeat the procedure for each
panel.(B,C)

Preparation of the refrigerant pipe
Prepare the pipe in steps. Unsuitably made joints are one of the main reasons for leakage, the joints
must thus be made thoroughly and in accordance with the listed steps.
STEP 1: Cutting the pipe
• Use a pipe cutter which does not produce chips to cut the pipe.
• Determine the distance between the outdoor and indoor unit.
• Cut the pipes longer in order to ensure connecting the internal and external device normally.
STEP 2: Removal of chips
• Remove all chips from the part where the pipe was cut.
• Hold the pipe downward during cleaning so that the chips do not fall into the pipe.
