INSTALLATION RECOMMENDATIONS
NOTE: In some cases noise in the living area has been traced to
gas pulsations from improper installation of equipment.
1. Locate unit away from windows, patios, decks, etc. where
unit operation sound may disturb customer.
2. Ensure that vapor and liquid tube diameters are
appropriate for unit capacity.
3. Run refrigerant tubes as directly as possible by avoiding
unnecessary turns and bends.
4. Leave some slack between structure and unit to absorb
vibration.

When passing refrigerant tubes through the wall, seal
opening with RTV or other pliable silicon-based caulk.
(See Fig. 1.)
Avoid direct tubing contact with water pipes, duct work,
floor joists, wall studs, floors, and walls.
Do not suspend refrigerant tubing from joists and studs with
a rigid wire or strap which comes in direct contact with
tubing. (See Fig. 1.)
Ensure that tubing insulation is pliable and completely
surrounds vapor tube.
When necessary, use hanger straps which are 1 in. (25.4
mm) wide and conform to shape of tubing insulation. (See
Fig. 1.)
Isolate hanger straps from insulation by using metal
sleeves bent to conform to shape of insulation.
