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, and so forth
where unit operation sounds may disturb customer.
2. Ensure that vapor- and liquid-tube diameters are appropriate to
capacity of unit.
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.
5. When passing refrigerant tubes through the wall, seal opening
with RTV or other pliable silicon based caulk. (See Fig. 2.)
6. Avoid direct tubing contact with water pipes, duct work, floor
joists, wall studs, floors, and walls.
7. Do not suspend refrigerant tubing from joists and studs with a
rigid wire or strap that comes in direct contact with tubing.
(See Fig. 2.)
8. Ensure that tubing insulation is pliable and completely sur-
rounds vapor tube.
9. When necessary, use hanger straps which are 1 in. wide and
conform to shape of tubing insulation. (See Fig. 2.)
10. Isolate hanger straps from insulation by using metal sleeves
bent to conform to shape of insulation.
When outdoor unit is connected to factory-approved indoor unit,
outdoor unit contains system refrigerant charge for operation with
indoor unit of the same size when connected by 15 ft of
field-supplied or factory-accessory tubing. For proper unit opera-
tion, check refrigerant charge using charging information located
on control box cover.
IMPORTANT: Maximum liquid line size is 3/8-in. O.D. for all
residential applications including long line.
IMPORTANT: Always install a liquid line filter drier on any
system using existing field service line sets and or existing indoor
coil or fan coil units. Always use a filter direr on burnout unit
replacements.
