safety practices
and wear
protective
goggles when checking
or service
refrigerant
system.
2. Do not operate
compressor
or provide
any electric
power
to unit unless compressor
ternfinal
cover is in
place and secured.
3. Do not remove
compressor
ternfinal cover until all
electrical
sources
are disconnected.
4.
Relieve
all pressure
from system before touching
or
disturbing
anything
inside compressor
ternfinal
box
if refrigerant
leak is suspected
around
compressor
ternfinals.
5.
6.
Never attempt to repair soldered
connection
while
refrigerant
system
is under pressure.
Do not use torch to remove
any component.
System
contains
oil and refrigerant
under pressure.
To
remove
a component,
wear protective
goggles
and
proceed
as follows:
a. Shut off gas, then electrical
power to unit.
Install
lockout
tag.
b. Relieve
all pressure
from system
using both high
and low-pressure
ports.
c. Cut component
connection
tubing with tubing
cutter and remove
component
from unit.
d. Carefully
unsweat
remaining
tubing stubs when
necessary.
