SAFETY CONSIDERATIONS

Installing and servicing air-conditioning equipment ean be

hazardous due to system pressure and electrical compo

nents. Only trained and qualified service personnel should

install or service air-conditioning equipment.

Untrained personnel can perform basic maintenance func

tions such as cleaning coils and filters and replacing filters.

All other operations should be performed by trained service

personnel.

When working on air conditioning equipment, observe pre

cautions in the literature and on tags and labels attached to

unit. Follow all safety codes. Wear safety glasses and work

gloves. Use quenching cloth for brazing operations. Have

fire extinguisher available. Before installation, read these in

structions thoroughly. Consult local building codes and Na

tional Electrical Code (NEC) for special installation

requirements.

A WARNING

Electrical shock can cause personal injuiy or death. Be

fore installing or servicing system, be sure to turn off

main power to system. There may be more than one dis

connect switch. Turn olf indoor fan coil power as

applicable.

GENERAL

The Carrier 40QNH012 heat pump high wall fan coil unit

(Fig, 1) comes with supplemental electric heat (40QNE009

heat pmnp fan coil unit does not have electric heat). If your

application requires heating, heat pump units must be used

both outdoors and indoors. See Table 1 for recommended

system combinations.

The matched cooling and heat pump systems consist of an

outdoor section (condensing unit or heat pump) and an in

door section (fan coil). The outdoor section (38AN or 38BK)

is installed alongside the building structure. It can also be

installed on a flat roof, deck, or on an apartment building

balcony. The indoor section (40QNB009,012 or 40QNE009,

40QNH012) is mounted high on an interior wall that is con

venient for piping connection to the outdoor section. Two

sizes are available: 9,000 and 12,000 Btuh cooling capaci

ties. See Fig. 1 for system components. Table 1 for system

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obiigations.

Condensate piping can be directed through the inside wall to an approved drain or directed straight outside, NOTE: The piping hole for condensate line must be made at a downward slope to ensure proper drainage. See Mount Mounting Bracket on Wall section below for details. Step 3 — Mount Mounting Bracket on Wall *A clearance of 31^" is the absolute minimum, A clearance of 10” is recommended.

RIGHT SIDE PIPING CONNECTIONS 1. Carefully remove the tubing and the condensate drain tube from the shipping brackets. 2. Be careful not to bend or kink the tubing. Gently rotate the tubing 180 degrees. 3. Using a hand tube bender, carefully bend the tube ends until they coincide with the raceway opening. 4. Carefully position the indoor section onto the wall bracket. Be sure the tubing and drain tube are routed through the piping hole in the wall. 5.
PAGE 11
2. Connect piping to the indoor section: a. Shape tube with a tube bender so that the tube ends coincide with flare connections. b. Carefully remove the flare nut fitting from the indoor section tubing. c. Thoroughly clean all tubing connection points to pre vent foreign matter from entering the refrigerant circuit. d. Thread the 2 fittings by hand, making sure the threads fit smoothly and the flare seats evenly against the union. e. Tighten the 2 fittings securely.

communication, all of the following must be true for the con troller to work properly; 1. The power must be on to the fan coil unit. 2. The batteries in the controller must be good. 3. The controller must be within range of and pointed di rectly at the fan coil unit. 4. The fan coil unit’s 3-position switch must be set in the remote position. The remote controller includes a wall-mounted bracket. To install the bracket, attach bracket to the wall as shown in Fig.

will stop 30 seconds after the compressor stops. After 3 minutes, the indoor fan runs at ultra-low speed for 30 seconds. The normal dehumidification operation is re peated for the newly sensed room temperature. 3. When the room temperature is equal to or greater than 4® F below the selected temperature, the system operates as follows: The compressor and outdoor fan operate for 3 minutes. The indoor fan will operate at ultra-low speed and will stop 30 seconds after the compressor stops.

When shutting down the system for an extended period of time, it is advisable to remove the batteries. Consult distributor if any other equipment is turned on or shows signs of disrupted operation if you use the wireless remote controller, or if the system is turned on or shows signs of disrupted operation when the remote controller of any other equipment is used.

To Clean Indoor Unit Front Panel — if the front panel of the unit beeomes dirty or smudged, wipe the out side of the front panel with a soft dry eloth. If necessary, use a mild liquid detergent and wipe off carefully with a dry cloth. To Clean Outdoor Coil (Outdoor Unit) A WARNING Some metal parts and sharp fins of outdoor unit coil can cause personal injury during cleaning. Clean coil carefully.
PAGE 20
— After 5 minutes of operation, if the temperature indicated by the outdoor coil thermistor is not 4° F less than at the time the call for heating started, then a compressor failure is indicated. SERVICE If the System is in Heat Pump Heating Mode (38BK only) A WARNING When servicing unit, turn off all electric power to unit to avoid shock hazard or injury from rotating parts.
