4.UNIT INSPECTION

This product has been inspected at the factory and released to the transportation agency without

known damage. Inspect exterior of carton for evidence of rough handling in shipment. Unpack

carefully. If damage is found, report immediately to the transportation agency.

5.EQUIPMENT PROTECTION FROM ENVIRONMENT

The metal parts of the unit may be subject to rust or corrosion in adverse environmental conditions.

This oxidation could shorten the unit life. Salt spray or mist in seacoast areas, sulphur or chlorine

from lawn watering systems and various chemical contaminants from industries such as paper mills

and petroleum refineries are especially corrosive.

If the unit is to be installed in an area where contaminants are likely to be a problem, special attention

should be given to the equipment location and exposure.

Avoid having lawn sprinkler heads spray directly on the unit cabinet.

In coastal areas, locate the unit on the side of the building away from the waterfront.

Shielding provided by fence or shrubs may give some protection.

Regular maintenance will reduce the buildup of contaminants and help to protect the unit's finish.

! WARNING - Disconnect all electrical power to the unit before servicing. Disconnect power to

both the indoor and outdoor units.

NOTE: There may be more than one electrical disconnect switch. Failure to shut off power can

cause electrical shock resulting in personal injury or death.

Frequent washing of the cabinet, fan blade and coil with fresh water.

Regular cleaning and waxing of the cabinet with good automobile polish.

A good liquid cleaner may be used several times a year to remove matter that will not wash

off with water.

The best protection is frequent cleaning, maintenance and minimal exposure to contaminants.

6.INSTALLATION

6.1.GENERAL

These units are designed for outdoor installations. They can be mounted on a slab or rooftop. It

is important to consult your local code authorities at the time the first installation is made.

Check following points before attempting any installation:

Structural strength of supporting members.

Clearances and provision for servicing.

Power supply and wiring.

Location for minimum noise, where operating sounds will not disturb owner or neighbors.

Location where there is no risk of combustible gas leakage.

Location where external water drainage cannot collect around the unit.

Location where roof runoff water does not pour directly on the unit. Provide gutter or other

shielding at roof level. Don't locate unit in an area where excessive snow drifting may occur

or accumulate.

Provide a level concrete slab. To prevent transmission of noise or vibration, slab should not be connected

to building structure. Some sort of sound-absorbing material should be placed between the condenser

and the slab. A good material to use is rubber and cork pad.

For rooftop application, make sure the building construction can support the weight and that proper

consideration is given to the weather-tight integrity of the roof. The condensing unit contains moving

parts and can vibrate. Therefore, sound is also a consideration in rooftop applications.

! WARNING - Install the unit securely in a place that can bear the weight of the unit. When installed

in an insufficiently strong place, the unit could fall causing injury.

6.2.UNIT CLEARANCES

The minimum clearances for the unit are illustrated in Figure 3. Condenser air enters from three sides.

Air discharges upward from the top of the unit. Refrigerant tube and electrical connections are made

from the service access area. The most common application will find the unit best located about 10"

from back wall with connection side facing the wall. This application minimizes exposed tubing and

wiring, minimizing the space for youngsters to run around the unit with subsequent damage to the

tubing or wiring.

In more confined application spaces, such as corners provide a minimum of 10" clearance on all air

inlet sides. For service access to the compressor and control box, allow 18" minimum clearance. Ensure

top is unobstructed. If units are to be located under an overhang, there should be a minimum of 36"

clearance and provision made to deflect the warm discharge air out from the overhang.

In order to have an unrestricted air flow, owners should be advised to avoid lawn mower discharge

toward the unit depositing debris on the fin coil surface reducing the unit efficiency.

6.3.REFRIGERANT PIPING

The refrigerant piping is very important as it affects the proper operation and efficiency of the air

conditioning system. Note the following guidelines:

Only refrigeration-grade copper piping (dehydrated and sealed) should be used. Take extreme care to keep

the refrigerant tubing clean and dry prior to and during installation. If in doubt, blow out the tubing

with dry nitrogen to remove any chips or debris before connection. Always keep tubing sealed until it is

in place and the connections are to be made.

Refrigerant piping should be as short as possible, with a minimum of elbows or bends, to avoid capacity

loss and increased operating costs.

Refrigerant lines must be adequately supported. If metal strapping is used to secure the tubing, do not allow

the strapping to directly contact the tubing. Use a closed cell insulation to separate the strapping from the

tubing.

Do not kink or twist the tubing.

Refrigerant piping should not be installed in a cement slab, as this limits access to the refrigerant should a

leak be suspected.

To ensure good oil return to the compressor, it is important to pitch the horizontal suction line toward

the compressor, approximately 1/2" for every 10' of line.

Line Insulation

Suction line requires insulation in order to prevent condensation from forming on the piping and to

prevent heat gain caused by surrounding air. Generally 3/8" wall thickness of Armflex or equivalent

is satisfactory. In severe application (hot, high humidity areas) greater thickness may be required.Apply

the line insulation by sliding it on the sealed tuing before cutting and making connections.

Liquid line does not necessarily need insulation, however, if they are exposed to high ambient temperatures

(i.e. kitchen, boiler rooms, hot attics & rooftop surface), then, they should be insulated. Make sure to

use the proper size tubing for the liquid line to prevent liquid refrigerant flashing to a vapor within

the liquid line.

Do not allow the vapor line and liquid line to touch together. This would cause an undesirable heat

transfer resulting in capacity loss and increased power consumption.

Refrigerant Line Sizing

Check the following table (Table 3) for correct suction and liquid line sizes for any combination of

the unit size and the maximum refrigerant line length.

Table 3:Refrigerant Line Sizing

The factory charge is sufficient for 15 feet of standard liquid line. For longer or shorter liquid line

lengths, adjust the charge as follows:

1/4" Line +/- 0.3 oz. Per foot

5/16" Line +/- 0.4 oz. Per foot

3/8" Line +/- 0.6 oz. Per foot

1/2" Line +/- 1.2 oz. Per foot.

Vertical Separation between Indoor and Outdoor Units

Maximum allowable vertical separations between indoor and outdoor units are illustrated in Figure

4-B-1 and Figure 4-B-2. It's 70' when the indoor unit is below the outdoor unit (Figure 4-B-1), and 50'

when the indoor unit is above the outdoor unit (Figure 4-B-2).

To ensure good oil return to the compressor when the indoor unit is below the outdoor unit, suction

line oil trap should be used as illustrated in Figure 4-B-1.

Tubing Connections

! CAUTION - Use extreme caution in removing the caps from the suction and liquid line fittings, as

there is pressure present. A fitting is on the liquid line to remove pressure.

! CAUTION - Heat Pumps are charged with refrigerant. Heat Pump liquid and suction valves are

closed to contain the charge within the unit. Do not force the valve stem against the retaining ring. If

the valve stem is backed out past the retaining ring, system pressure could force the valve stem out

of the valve body and possibly cause personal injury.

! CAUTION - The piston is in the accessory bag. Don't forget to take it out and put into the indoor

liquid pipe orifice.
