SAFETY CONSIDERATIONS

Installing and servicing air-conditioning equipment can 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-

structiens thoroughly. Consult local building codes and Na-

tional Electrical Code (NEC) for special installation

requirements.

Electrical shock cancause personal injury 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 off indoor fan coil power as

applicable.

GENERAL

The Carrier 40QNHOI 2 heat pump high wall fan coil unh

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

heat pump 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

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

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. m 8 "....._ Step 3 -- Mount Mounting Bracket on Wall l. Decide how refrigerant will be piped.

Check that the indoor section is mounted level to ensure proper condensate drainage and to avoid possible water damage. Be sure the drain tube is sloped toward the outside and is not kinked or bent. Ensure that any drain extension is made outside the wall. NOTE: Use either point "A" or point "B." Fig.

2. Connect piping to the indoor section: IMPORTANT: Be sure the drain hose has no slack which might form a trap. Do not insert a trap in the drain line, the drain is internally trapped. 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 seetinn tubing. c.

START-UP communication, all of the following must be true for the controller to work properly: Complete the following checks and the Start-Up Checklist on pages CL-1 and CL-2 before system start-up. 1. Check condensate drainage system. Refer to Fig. 4 and 10. Add water to check the drainage flow. If water does not flow steadily, check the pipe slope or see if there are any restrictions. 2. Make sure all wiring connections are correct and tight. 1. The power must be on to the fan coil unit. 2.

Air Circulation Mode (Fan Operation Only) -- When Air Circulation mode is selected, the indoor fan will operate continuously in the selected speed (high, medium, low, or auto.). If the Auto. mode is selected, the indoor fan will operate at low speed. The compressor and outdoor fan are off. The reversing valve (QNE/H only) will remain in the last operating mode.
