Unitary Ducted Split AC & HP

2.4 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.

5). When passing refrigerant tubes through the wall, seal opening with RTV or other pliable

silicon--based caulk.(See Fig. 5.)

6). Avoid direct tubing contact with water pipes, duct work, oor joists, wall studs, oors, 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. 5.)

8). Ensure that tubing insulation is pliable and completely surrounds vapor tube.

9). When necessary, use hanger straps which are 1 in. wide and conform to shape of tubing

insulation. (See Fig. 5.)

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 good for 25 ft.

For proper unit operation, check refrigerant charge using charging information located on
