Safety Instruction: 

The equipment has been designed and manufactured to meet international safety standards but, like any 
mechanical/electrical equipment, care must be taken if you are to obtain the best results. 

•  Service and maintenance of this unit, that is Electrical and Mechanical in nature should be carried out by technically 

trained and competent personnel. They should be familiar with Local Standards and Codes of Practice. 

•  When carrying out unit maintenance, ensure that the equipment is disconnected from the electrical power supply. 
•  Never Place the unit in flammable atmosphere. Do not bypass any Electrical and Product safety devices. 
•  Refrigerant used in this unit is classified under the COSHH regulations as an irritant, with set Occupational 

Exposure Levels (OEL) for consideration if installed in confined or poorly ventilated areas. 

•  Use personal protective equipment's (PPE's) while installation and commissioning the product at site. 
•  Under all Circumstances, any applicable local safety regulations requirement must be fulfilled. 
•  Ensure the proper earthing should be connected to condensing unit before starting the Unit. 
•  The condensing unit must only be used for its designed purposes with approved Refrigerants & lubrication oil, 

proper Electrical supply and within its scope of application. 

•  Do not start the unit until it is charged with refrigerant. Never charge the oxygen in the Unit/System 

•  Ensure that materials and wiring do not touch high temperature areas of the compressor & discharge line. 
• 

Never install a system and leave it unattended when it has no charge, a holding charge, or with the service valves 
closed without electrically locking out the system. 

•  Under running condition, the compressor and the tubing can reach temperatures high enough to induce burns 

and in case of leak of refrigerant avoid eye contact. 

•  During maintenance, if Brazing or De-brazing process is required. Kindly ensure that there should not be any 

refrigerant & oil inside the system pipe or the brazing area. 

•  Company shall not be responsible for any kind of accidents occur at sites due lack of sense of responsibility, 

Mis-handling, Wrong practice of installation and not following the instructions as mentioned above. 

• 
•  Do not pressurize the unit above 300 PSI in ideal conditions with Nitrogen, dry air,& Refrigerant. Always use pressure 

regular valve while connecting to Nitrogen cylinder. 

All units are shipped with a holding charge of dry nitrogen inside at a low but positive pressure. It is very important 
to check that this holding pressure exists at the time you receive each unit from us or our authorized representatives. 
Please inform us or our authorized representative if the holding charge is non-existent. Failure to do 
so could void the claim for other related system faults at a later period. 

Transit damage is essentially an insurance claim and is not covered under manufacturing defect. It is also 
advisable to inspect the rest of the unit for obvious physical damage and inform us or our authorized 
representative in case any is discovered. 

•  During transportation & storage, always keep the unit in vertical/upright position. 
•  Always move the CDU Boxes or pallet using shrink wrap packaging and all the boxes should be tighten 

properly with strapping tape. Because it may cause transit damage. 

• 
•  Always move the units in fully closed container/Vehicle to avoid from rain. 
•  Handle the unit with care. The packaging allows the use of a forklift or pallet jack for handling. Use appropriate 

and safe handling equipment. 

•  It is recommended not to open the packaging before the unit is at final place for installation. 

All the products are not released for use with caustic, poisonous or flammable substances. 

Do not stack single boxes on top of each other without pallet in any case.
