ELECTRICAL SHOCK HAZARD
•
Disconnect and lock out power before servicing.
•
Discharge all capacitors for a minimum of two minutes before servicing.
•
Use compressor with grounded system only.
•
Molded electrical plug must be used when required.
•
Refer to original equipment wiring diagrams.
•
Electrical connections must be made by qualified electrical personnel.
•
Failure to follow these warnings could result in serious personal injury.
PRESSURIZED SYSTEM HAZARD
•
System contains refrigerant and oil under pressure.
•
Remove refrigerant from both the high and low compressor side before
removing compressor.
•
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.
•
Use only approved refrigerants and refrigeration oils.
•
Personal safety equipment must be used.
•
Failure to follow these warnings could result in serious personal injury.
FIRE HARD
•
Open flames and smoking are strictly forbidden.
•
Continuously check if the ambient atmosphere is nonexplosive.
•
During service make sure that:
o
The area is well ventilated.
o
The materials and equipment used are suitable for use under
explosive conditions.
o
Only non-sparking tools are used.
o
Anti-static gloves and clothes are used.
o
A build-up of electrostatic charges is avoided.
•
In the case of explosive atmosphere:
o
Immediately stop the compressor and de-energize the power
supply of the compressor and any other electrical component/
equipment such as crankcase heater.
o
No unshielded flame is allowed.
•
Before opening the refrigeration, system or working on it with an unshielded
flame:
o
Continuously check if the ambient atmosphere is non-explosive
and ensure proper ventilation of the room before creating any
naked flame. No naked flame is allowed in an explosive
atmosphere.
•
When atmosphere reaches a dangerous concentration of flammable gas:
o
Avoid any ignition source and ventilate the room further.
•
Closed all valves tightly if any parts of the refrigeration systems are charged
with flammable refrigerants.
