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.

Recognize safety information. This is the safety-alert symbol

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

manuals, be alert to the potential for personal injury.

Understand these signal words; DANGER, WARNING, CAU-

TION, and NOTE. These words are used with the safety-alert

symbol. DANGER identifies the most serious hazards which will

result in severe personal injury or death. WARNING signifies

hazards which could result in personal injury or death. CAUTION

is used to identify unsafe practices which would result in minor

personal injury or product and property damage. NOTE is used to

highlight suggestions which will result in enhanced installation,

reliability, or operation.

Before installing, modifying, or servicing system, main elec-

trical disconnect switch must be in the OFF position. There

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.

Puron® (R-410A) systems operate at higher pressures than

standard R-22 systems. Be certain that service equipment is

rated for Puron®. Some R-22 service equipment may not be

acceptable. Check with your distributor.

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 to

capacity of unit.

3. Run refrigerant tubes as directly as possible by avoiding

unnecessary turns and bends.

4. When passing refrigerant tubes through the wall, seal opening

with RTV or other pliable silicon-based caulk. (See Fig. 2.)

5. Avoid direct tubing contact with water pipes, duct work, floor

joists, wall studs, floors, and walls.

6. 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.)

7. Ensure that tubing insulation is pliable and completely sur-

rounds vapor tube.

8. When necessary, use hanger straps which are 1 in. wide and

conform to shape of tubing insulation. (See Fig. 2.)

9. Isolate hanger straps from insulation by using metal sleeves

bent to conform to shape of insulation.

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.

IMPORTANT: Only install the factory-supplied Puron® (R-

410A) air conditioner liquid line filter drier. Obtain replacement

filter driers from your local distributor.
