injury. Installing, starting up, and servicing equipment can be
hazardous due to system pressure, electrical components, and
equipment location.
Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation. There
may be more than one disconnect switch. Tag all
disconnect locations to alert others not to restore power
until work is completed.
When installing the equipment in a small space, provide
adequate measures to avoid refrigerant concentration
exceeding safety limits due to refrigerant leak. In case of
refrigerant leak during installation, ventilate the space
immediately. Failure to follow this procedure may lead to
personal injury.
DO NOT USE TORCH to remove any component. System
contains oil and refrigerant under pressure.
service,
To remove a component, wear protective gloves and
goggles and proceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from
system using both high and low-pressure ports.
c. Traces of vapor should be displaced with nitrogen
and work area should be well ventilated. Refrigerant
in contact with an open flame produces toxic gases.
d. Cut component connection tubing with tubing cutter
and remove component from unit. Use a pan to catch
any oil that may come out of the lines and as a gage
for how much oil to add to the system.
e. Carefully unsweat remaining tubing stubs when
necessary. Oil can ignite when exposed to torch
flame.
