SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service, maintenance,

or use can cause explosion, fire, electrical shock, or other

conditions which may cause death, personal injury, or property

damage. Consult a qualified installer, service agency, or your

distributor or branch for information or assistance. The qualified

installer or agency must use factory-authorized kits or accessories

when modifying this product. Refer to the individual instructions

packaged with the kits or accessories when installing.

Follow all safety codes. Wear safety glasses, protective clothing,

and work gloves. Use quenching cloth for brazing operations.

Have fire extinguisher available. Read these instructions thor-

oughly and follow all warnings or cautions included in literature

and attached to the unit. Consult local building codes and National

Electrical Code (NEC) for special requirements.

When you see this symbol on the unit and in instructions or

manuals, be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING, and CAU-

TION. These words are used with the safety-alert symbol. DAN-

may be more than 1 disconnect switch. Lock out and tag

switch with a suitable warning label. Electrical shock can

cause personal injury or death.

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 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 which 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 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.

IMPORTANT: Always install a liquid-line filter drier. Refer to

Product Data Digest for appropriate part number. Obtain filter

drier from your distributor or branch.
