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 un-
necessary turns and bends.
! !
4. Leave some slack between structure and unit to absorb vi-
bration.
5. When passing refrigerant tubes through the wall, seal open-
ing with RTV or other pliable silicon- -based caulk. (See Fig.
1.)
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 which comes in direct contact with
tubing.(See Fig. 1.)
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. 1.)
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
AHRI rated indoor unit when connected by 15 ft. (4.57 m) of
field- -supplied or factory accessory tubing. For proper unit
operation, check refrigerant charge using charging information
located on control box cover and/or in the Check Charge section of
this instruction.
IMPORTANT: Maximum liquid- -line size is 3/8- -in. OD for all
residential applications including long line applications.
IMPORTANT: Always install the factory- -supplied liquid- -line
