SAFETY CONSIDERATIONS GENERAL Installing, starting up, and servicing air--conditioning equipment can be hazardous due to system pressures, electrical 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.

Ideal installation locations include: Indoor Unit S A location where there are no obstacles near inlet and outlet area. S A location which can bear the weight of indoor unit. S Do not install indoor units near a direct source of heat such as direct sunlight or a heating appliance. S A location which provides appropriate clearances as outlined in Fig. 3 (pg. 5). Outdoor Unit S A location which is convenient to installation and not exposed to strong wind.

1. Use a rigid base to support unit in a level position. NOTE: For applications requiring cooling with outdoor temperatures below 55_F (13_C), a low ambient control field--installed accessory is available. Consult the Installation Instruction for the low ambient kit for further information. If the installation location may be exposed to strong wind , use a wind baffle. Check with your Bryant representative to obtain drawings for wind baffles. Strong wind Fig. 10 --- High Wind Installation 2.

INSTALL ALL POWER AND INTERCONNECTING WIRING TO OUTDOOR UNITS 538M*C / 619M*C -- 538M*Q / 619M*Q 1. Mount outdoor power disconnect. 2. Run power wiring from main box to disconnect per NEC and local codes. 3. Remove field wiring cover from unit by loosening screws. 4. Remove caps on conduit panel. 5. Connect conduit to conduit panel. (See Fig.12 ) 6. Properly connect both power supply and control lines to terminal block per the connection diagram for the appropriate unit capacity and voltage. (See Fig.

CONNECTION DIAGRAMS CONNECTING CABLE CONTROL 538M*C / 619M*C -- 538M*Q / 619M*Q CONTROL CONNECTING CABLE CONNECTING CABLE Notes: 1. Do not use thermostat wire for any connection between indoor and outdoor units. 2. All connections between indoor and outdoor units must be as shown. The connections are sensitive to polarity. 3. On the 18k and 24k units, the “S” terminal “CONTROL” output is pulse DC with a potential AC voltage shock hazard. Fig.

538M*C / 619M*C -- 538M*Q / 619M*Q INSTALL ALL POWER, INTERCONNECTING WIRING, AND PIPING TO INDOOR UNIT. 1. Run interconnecting piping and wiring from outdoor unit to indoor unit. 2. Run interconnecting cable through hole in wall (outside to inside). 3. Lift indoor unit into position and route piping and drain through hole in wall (inside to outside). Fit interconnecting wiring into back side of indoor unit. 4.

UNIT DAMAGE HAZARD Failure to follow this caution may result in equipment damage or improper operation. Deep Vacuum Method The deep vacuum method requires a vacuum pump capable of pulling a vacuum of 500 microns and a vacuum gage capable of accurately measuring this vacuum depth. The deep vacuum method is the most positive way of assuring a system is free of air and liquid water. (See Fig. 18) 5000 4500 4000 3500 3000 2500 2000 1500 1000 500 Never use the system compressor as a vacuum pump.

START--UP Test Operation Perform test operation after completing gas leak and electrical safety check. (See Fig.. 20) SYSTEM CHECKS 1. Conceal the tubing where possible. 2. Make sure that the drain tube slopes downward along its entire length. 3. Ensure all tubing and connections are properly insulated. 4. Fasten tubes to the outside wall, when possible. 5. Seal the hole through which the cables and tubing pass. 538M*C / 619M*C -- 538M*Q / 619M*Q INDOOR UNIT AUTO/COOL Manual Button Fig.

TROUBLESHOOTING For ease of service, the systems are equipped with diagnostic code display LEDs on both the indoor and outdoor units. The outdoor diagnostic display is an LED on the outdoor unit board and is limited to very few errors. However, it is useful in identifying special error codes like a failure of the outdoor coil sensor on heat pumps. The indoor diagnostic display is a combination of flashing LEDs on the display panel or the front of the unit.
