• Consult local building codes and National Electrical

Code (NEC, U.S.A.) for special installation requirements.

• Control wiring should be 18 gage.

• Use only type "G" or"C" fuses.

• Use single length power cable without extension.

• Allow sufficient space for airflow clearance on condensing units for wiring, refrigerant piping, and servicing unit.

See Fig.

1 and 2 for minimum required distances between unit and walls or ceilings.

• Indoor and outdoor units should be installed at a minimum of 10 ft apart.

Maximum line length is 130 ft, and vetlical separation is 66 ft.

• Do not install indoor units near a direct source of heat such as direct sunlight, steam or flame.

SAFETY CONSIDERATIONS

Installing, stalling up, and servicing air-conditioning equipment can be hazardous due to system pressures, electric_d components, and equipment location (roofs, elevated structures, etc.).

Only trained, qualified installers and service mechanics should install, start-up, and service this equipment.

Untrained personnel can perform basic maintenance functions such as cleaning coils. All other operations should be performed by trained service personnel.

When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment.

Follow all safety codes.

Wear safety glasses and work gloves.

Keep quenching cloth and fire extinguisher nearby when brazing.

Use care in handling, rigging, and setting bulky equipment.

Do not bury more than 36 in. of refrigerant pipe in the ground.

If any section of pipe is buried, there must be a

6 in. vetlical rise to the valve connections on the outdoor units.

If more than the recommended length is buried, refrigerant may migrate to the cooler buried section during extended periods of system shutdown.

This causes refrigerant slugging and could possibly &image the compressor at start-up.

CARE AND MAINTENANCE

The following may be perforlned by the equipment owner

38BNB,BNE Outdoor Units

40BNB, BNE Indoor Units

To avoid the possibility of electric shock, before performing any cleaning and maintenance operations, always turn off power to the system by pressing the mode button on the remote control until the display shows "OFE" and turn off the sepal'ate disconnect switch located near the unit. If the indoor unit is on a separate switch, be sure to turn this disconnect off as well.

Do not wash filter in water over 120 F (to avoid shrinkage).

Do not expose filter to fire (to avoid fire &image).

Do not expose filter to direct sunlight.

Clean filter more frequently when air is extremely dirty.

Do not attempt to clean or service components in control box.

To Clean the Indoor Unit Front Panel -If the

fi'ont panel of the unit becomes dirty or smudged, wipe the outside of the panel with a soil diy cloth. Use a mild liquid detergent and wipe off cmelhlly with a @ cloth.

To Clean Indoor Coil--To

clean file coil, remove indoor unit front panel and vacuum the coil fins, using care not to bend or dalnage fins.

LUBRICATION -- Tile indoor-fan, automatic air sweep, and the outdoor-fan motol_ _u'e factory lubricated and require no oiling.

Air Filters for 38BNB,BNE Outdoor Units and

40BNB, BNE Indoor Units

Before performing recommended maintenance, be sure unit main power switch is turned off. Failure to do so may result in electric shock or injury from rotating fan blade.

CLEANING COILS--Coil should be washed out with water or blown out with compressed all: Clean coil annually or as required by location and outdoor air conditions.

Inspect coil monthly and clean as required.

Fins are not continuous through coil sections.

Dill and debris may pass through first section, become trapped between the row of fins and restrict outdoor unit airflow. Use a flashlight to determine if dirt or debris has collected between coil sections.

Clean coil as follows:

1. Turn off unit power and install lockout tag.

2.

Using a gmden hose or other suitable equipment, flush coil from the outside to remove dirt. Be sure to flush _dl dirt and debris from di'ain holes in base of unit. Fan motors are waterproof.

12

Operating your system with dirty air filters may &image the indoor unit and, in addition, can cause reduced performance, intermittent system operation, fi_st build up on the indoor coil, and blown fuses. Inspect and clean or replace the air filters monthly.

TO REMOVE AIR FILTERS -- Remove filters by pulling them straight out.

TO CLEAN OR REPLACE FILTERS -Filters can be vacuumed or washed in wtum watec Shake filter to remove any excess watel: and replace by sliding filter behind grille until filter snaps in place. If the filter has begun to break down or is torn, replace it. Replacement filters are available through a loc_d de_del:

SERVICE

The following should be performed by a qualified service technician.

Clean Condensate Drains--Clean all drains and

drain pans at the start of each cooling season. Check the flow by pouring water into the drain.

Clean or Replace Drain Pan

-The drain pan should only be cleaned or replaced by a qualified service technician.

1. Place a plastic sheet on the floor to catch any water that may spill from the drain pan.

2.

Remove the intake grille and distribution assembly.

3.

Remove the condensate water in the drain pan by letting water drain into a 3-gallon bucket.
