Only refrigeration-grade copper piping (dehydrated and sealed) should be used. Take extreme care to keep
the refrigerant tubing clean and dry prior to and during installation. If in doubt, blow out the tubing
with dry nitrogen to remove any chips or debris before connection. Always keep tubing sealed until it is
in place and the connections are to be made.
Refrigerant piping should be as short as possible, with a minimum of elbows or bends, to avoid capacity
loss and increased operating costs.
Refrigerant lines must be adequately supported. If metal strapping is used to secure the tubing, do not allow
the strapping to directly contact the tubing. Use a closed cell insulation to separate the strapping from the
tubing.
Do not kink or twist the tubing.
Refrigerant piping should not be installed in a cement slab, as this limits access to the refrigerant should a
leak be suspected.
To ensure good oil return to the compressor, it is important to pitch the horizontal suction line toward
the compressor, approximately 1/2" for every 10' of line.
Line Insulation
Suction line requires insulation in order to prevent condensation from forming on the piping and to
prevent heat gain caused by surrounding air. Generally 3/8" wall thickness of Armflex or equivalent
is satisfactory. In severe application (hot, high humidity areas) greater thickness may be required. Apply
the line insulation by sliding it on the sealed tuing before cutting and making connections.
Liquid line does not necessarily need insulation, however, if they are exposed to high ambient temperatures
(i.e. kitchen, boiler rooms, hot attics & rooftop surface), then, they should be insulated. Make sure to
use the proper size tubing for the liquid line to prevent liquid refrigerant flashing to a vapor within
the liquid line.
Do not allow the vapor line and liquid line to touch together. This would cause an undesirable heat
transfer resulting in capacity loss and increased power consumption.
