Be sure to observe the cautions specified here as they include important items related to safety.
The indications and meanings are as follows.
After reading this manual, be sure to keep it together with the owner's manual in an accessible place.
Could lead to death, serious injury, etc.
Could lead to serious injury in particular environments when operated incorrectly.
WARNING
CAUTION
connection by the supply authority before connecting to the system.
Do not install it yourself (customer).
Perform the installation securely referring to the
installation manual.
Install the unit securely in a place which can bear the
weight of the unit.
Attach the electrical part cover to the indoor unit and
the service panel to the outdoor unit securely.
Be sure to use the part provided or specified parts for
the installation work.
Check that the refrigerant gas do not leak after
installation is completed.
Use the specified wires to connect the indoor and the
outdoor units securely and attach the wires firmly to
the terminal board connecting sections so the stress
of the wires is not applied to the sections.
Incomplete installation could cause injury due to fire, electric shock,
the unit falling or a leakage of water Consult the dealer from whom
you purchased the unit or authorised installer.
Incomplete installation could cause a personal injury due to
fire, electric shock, the unit falling or a leakage of water.
When installed in an insufficient strong place, the unit could f all
causing injured.
Incomplete connecting and fixing could cause fire.
The use of defective parts could cause an injury or leakage of
water due to a fire, electric shock, the unit falling, etc.
If the electrical part cover if the indoor unit and/or the service
panel if the outdoor unit are not attached securely, it could result
in a fire or electric shock due to dust, water, etc.
WARNING
Perform electrical work according to the installation
manual and be sure to use an exclusive circuit.
If the capacity of the power circuit is insufficient or there is
incomplete electrical work, it could result in a fire or an electric
shock.
4

3.2. Levelling of Airconditioner
After placing the unit on Channel/concrete structure
maintain the levelling of unit towards rear side with
10mm slope so as to ensure free flow drainage.
Water seepage problem may happen due to improper
levelling of unit.
3.4. Condensate Drain pipe
3.3. Shelter Cutout sealing
Angle flanges (4 nos) to be fixed with shelter wall after
installation. These flanges are to be fixed with shelter
wall after installation so as to prevent any leakage in
shelter. after fixing the flanges; apply silicon sealant
on edges of flanges to make complete leak free
cut-out. These are not the part of unit accessories.
1. Air conditioner is provided with one flexible drain
pipe, which shall be connected to metal Drain pipe
of unit & should be routed through gap between
shelter wall and condensing unit (see fig. C).
2. Do Not leave drain pipe open, your airconditioner
may suck condensate water and cause splitting of
water inside the shelter.

The air which contains moisture remaining in the refrigeration cycle may cause
malfunction of compressor.
1. Confirm the both liquid valves& gas valves are set to closed position.
2. After connecting the piping, check the joints for gas leakage with gas leal
detector.
3. Remove the service port nut, and connect the gauge manifold and vacuum
pump to the service port by charge hose.
4. Vacuum the indoor unit & connecting pipes until the pressure in them lowers
to below 76 cmHg.
5. Remove the valve stem nuts. and fully open the stems of service valves with
hexagon wrench. & Tight the flare nuts of indoor & outdoor unit.
6. Purge the gas qty-80grams in each circuit to remove moist air contents.
7. Disconnect the charge hose and fit the nut to the service port.
(Tightening torque:1.8kg.m)
3.5. Air purging of inter connection & Indoor unit
The Airconditioner is equipped with fine air filter (2 nos.). The Air filter are at
front of unit shall be checked and cleaned every month or more often
if necessary.
