designed to suit Indian climatic conditions & are tested as per standards IS: 1391 part 2.
The air-conditioner is manufactured under strict quality control system. This service manual helps to know
more about air-conditioners along with its specifications, working etc. However the technician must refer
to installation manual before using this manual because in many cases the problem lies with installation
due to lack of knowledge & skills etc. This manual includes tips for service personnel, safety precautions
and recommended tools &equipment’s apart from technical details of air-conditioners. At the outset it is
better to note that the refrigeration system which is used in the air-conditioner is almost similar to Godrej

The manual is designed for the qualified/trained and well experienced service personnel engaged in
providing efficient service to valued customers. We certainly referred to many books, journals and other
documents to enable us to provide you updated information. An inexperienced and unauthorized person
should not attempt to make any adjustments or repair the air-conditioning unit as this may cause damage.
Also in case of new air-conditioners, it may lead to warranty becoming null & void.
All air-conditioners need careful handling & regular maintenance to extend its life. You as a service
provider have a responsibility to maintain the air-conditioner in good working condition, during its life
time. Therefore, it is essential that before you start any repair or diagnosis on the air-conditioner, please
read this service manual completely. Also the user manual supplied with the air-conditioner can tell you
how to remedy some of the problems that aren’t due to the unit failures and operation of various controls.

Safety Precautions

Godrej & Boyce Mfg. Co. Ltd, HO Service, Mumbai SM 3274 - Page 5 of 23
To minimize the risk of personal injury or property damage it is important that the following safe servicing
practices be observed.
1) Read carefully the instruction booklet supplied with the air-conditioner from time to time. Be sure you
are operating air-conditioner properly.
2) Know the location of customer’s air-conditioner circuit breakers or fuses.
3) Before servicing the air-conditioner, UNPLUG the power cord before performing any repairs or
removing any panel. Note Except for electrical & partly mechanical performance testing, none of repairs
require electrical power.
4) Be careful when handling air-conditioner grille and access panel, parts or any components which may,
have sharp edges. Avoid placing your hand into any area of the air-conditioner which can’t first visually
inspect for sharp edges.
5) Always use the correct tools for a job and make sure tools are in good condition. Worn, faulty and
misused tools can cause accidents.
6) Never interfere with or bypass the operation of any switch, component or feature of the air-conditioner.
7) Use only replacement parts of the same size and capacity as per the list of parts. If you have any
questions contact our branch.
8) When replacing any component, be sure any green ground wires are connected securely in their original
position to avoid danger of shock or short circuit.
9) Before connecting the power supply, make sure no un insulating wires or terminals are touching the
cabinet. Electrical wiring and all grounds must be correctly reconnected and secured away from sharp
edges, components and moving parts. All panel and covers etc. should be reinstalled before the
air-conditioner is plugged in.
10) The line cord must be plugged into a grounded, three plug pin. Never cut or remove the third
(ground) or top pin from the power cord plug.
11) Do not substitute ordinary wire for any internal wiring of air-conditioner. The wire must carry heavy
current and can be subjected to heat. It is very important that all connections are tight and secure.
12) Make an insulation test, after the air-conditioner is repaired, to protect the customer from being
exposed to shock hazards. (Value to be not less than 1M)
13) Always work in an well ventilated space/area during sealed system repairs.
