Use only refrigerant grade (dehydrated and sealed) copper
tubing to connect the air conditioner with the indoor evapora-
tor. After cutting the tubing, install plugs to keep refrigerant
tubing clean and dry prior to and during installation. Tubing
should always be cut square keeping ends round and free
from burrs. Clean the tubing to prevent contamination. The
liquid line must be insulated if more than 50 ft. of liquid line will
pass through an area that may reach temperatures of 30°F
or higher than outdoor ambient. Never attach a liquid line to
any uninsulated portion of the suction line.
Do NOT let refrigerant lines come in direct contact with plumb-
ing, ductwork, floor joists, wall studs, floors, and walls. When
running refrigerant lines through a foundation or wall, open-
ings should allow for sound and vibration absorbing material
to be placed or installed between tubing and foundation. Any
gap between foundation or wall and refrigerant lines should
be filled with a pliable silicon-based caulk, RTV or a vibration
damping material. Avoid suspending refrigerant tubing from
joists and studs with rigid wire or straps that would come in
contact with the tubing. Use an insulated or suspension type
hanger. Keep both lines separate and always insulate the
suction line.
Insulation is necessary to prevent condensation from forming
and dropping from the suction line. Insulation tube with 3/8”
min. wall thickness is recommended. In severe conditions
(likely to exceed 86°F and a relative humidity of 80%) 1/2”
insulation may be required. Insulation must be installed in a
manner which protects tubing and connections from damage
and contamination.
Please use a HVAC flushing solvent to clean lineset of any
oil or debris from the existing system.
note:
If changing refrigerant, the indoor coil and metering
device must be replaced.
