ailure to replace and tighten the caps may result in refrigerant leakage. In
a
ddition, do not damage the insides of the valve caps as they act as a seal to
p
revent refrigerant leakage.

Use sealant to seal the ends of the thermal insulation around the pipe connection
s
ections to prevent water from entering the thermal insulation
