IMPORTANT NOTES
EXTREME OPERATIONS CONDITIONS
• Do not allow the customer to t the air conditioning unit.
Installation of the unit must be carried out by either the
local distributor or a specialist tter. The tter is respon-
sible for any problems caused by a faulty installation.
• The installation instructions must be followed closely.
A faulty installation can lead to water leaks, electrical
discharges or res.
• Do not use any coolant other than R22. The mixture
of gases in the cooling cycle can lead to damage or
impaired performance.
• Check that the mounting and fastening devices are
sufcient to withstand the weight of the unit. If they are
not, the unit may fall and cause an accident.
• Ensure that all fastening devices and accessories are
used. Use of any items not shown can lead to water
leaks, electrical discharges or res.
• Carry out electrical connections in accordance with
local regulations and the instructions laid down in the
installation manual. Ensure that the proper cables have
been used. If they have not, this may cause electrical
discharges or res.
• While connecting the outdoor unit, keep the cabling
conduit rigid. Faulty cable tting can cause overhea-
ting, electrical discharges or re at these connections.
• The system must always be earthed. If it is not, this
may lead to electrical discharges.
• Do not t units in places which may be affected by
leaks of inammable gas. If the gas is in circulation
around the units, this may cause explosions.
• Place the drainage hose in a suitable position. An
improperly tted hose will force the water back to the
room, thus damaging the furniture.
• This air conditioning system is for home use only. Do
not use it for any unspecied applications: warehouses,
foodstuff depots, animals, plants, precision machinery,
works of art etc. These items may be damaged as a
result.
• Use the voltage shown. If this is not used, it may cause
a re or other problems.

2.1 INITIAL CHECK
• Install indoor unit allowing for enough clearance around
the unit so there is room for handling and maintenance
operations as shown below:
• Avoid any obstacles that could impair air take-up or
discharge ow.
• Do not install the indoor nit in a machinery workshop or
in a kitchen where oil or smoke mist could ow into the
indoor unit. Oil would be deposited in the heat exchan-
ger resulting in a reduced unit performance. Also, inter-
nal plastic parts could be deformed or they could even
break as a result.
• Note the following items when the indoor unit is to be
installed in a hospital or premises where electromag-
netic waves from medical equipment may be present.
A) Do not install the indoor unit where electromagnetic
waves directly impinge on the electric box, the remote
control switch or the remote control cable.
B) Install the unit as far as possible from the electromag-
netic wave source. A 3 metre clearance should be
arranged.
C) Install a noise lter when the power supply produces
disturbing noises.
D) Select nal location and direction of the indoor unit
paying special attention to tubes, cables and mainte-
nance.
E) When selecting the indoor unit location, the air ducting
network should be borne in mind in order to facilitate
distribution.
• Do not install the indoor unit in an acid or alkaline envi-
ronment to preserve heat exchangers from any corro-
sion process.
2- INDOOR UNIT INSTALLATION
2.2 FIXING THE UNIT
- Use the appropriate fasteners for each structure type
paying special attention to any possible transmission
of vibrations and noise. Noise or vibration proof items
should be provided if it is considered to be necessary.
2.3 INDOOR UNIT INSTALLATION
• Insert and screw down a nut on each supporting rod.
• Lift the indoor unit and insert the rods in the holes pro-
vided on the mounting brackets.
• Place a washer and nut on each of the rods.
• Level out the machine and x it tightening so that nuts
are pressed against each other.
• It is advisable to place a lock nut against the lower nut
on the suspension rods.
2.4 DRAIN PIPE INSTALLATION
• Special care should be taken when laying drain tubing,
otherwise if any problem occurs the condensed water
of the evaporator could spill.
• Do not place the drain pipe in an upwards position
otherwise drain water would go back to the unit and
spill when the unit would stop.
• Do not connect the drain pipe to the sanitary drains,
waste water drains or any other drain facility if a trap is
not installed.
• When a common drain pipe is connected to other indoor
units, connection positions of each unit should be at a
higher level than the common pipe. The common pipe
length should be appropriate for the size and number
of existing units.
2.5 SUSPENSION OF THE INDOOR UNIT

tor without fail when the pipes are connected.
4. HEAT INSULATION ON THE PIPE JOINTS
- Put coupler heat insulator on the joints.
AIR PURGE
- Close the high pressure side valve fully.
- Check if the piping connections are secure.
- Check that the stems of both 3- way valves are closed
fully.
- Connect the gauge manifold service hose to the char-
ging port of the 3- way valve (side with the projection of
pushing in the valve core).
- Open the low pressure side valve of the gauge mani-
fold fully.
- Operate the vacuum pump and start pump down.
- Pump down the system for at least 15 minutes, then
check if the compound pressure gauge reads - 100kPa
(- 76 cm Hg, -1bar)
- At the end of pump down, close the low pressure side
gauge of the gauge manifold fully and stop the vacuum
pump.
- Slowly loosen the valve stem of the 3- way valve. When
the compound pressure gauge reading reaches 1- 2
kg/ cm2, retighten the valve stem and disconnect the
service hose from the 3- way valve charging port.
(If the stem of the 3- way valve is opened fully before
the service hose is disconnected, it may be difcult to
disconnect the service hose.)
