(356mm). 1- Detach wooden base protection before rigging. 4- Duct must be attached to the roof mounting frame and not to the unit.
- Page 6 Make drain connection to the 1" N.P.T. drain coupling provided on unit. A trap must be installed between drain connection and an open vent for proper condensate removal. See figure 3. It is sometimes acceptable to drain condensate onto the roof or grade; however, a tee should be fitted to the trap to direct condensate downward.
- Page 7 Units may be installed at altitudes up to 2000 feet (610 m) When pressure testing gas lines, the gas valve must be above sea level without any modification. At altitudes disconnected and isolated. Gas valves can be damaged if above 2000 feet (610 m), units must be derated to match subjected to more than 0.5 psig (3.48kPa).
- Page 8 Do not apply power or close disconnect switch until installation is complete. Refer to start-up directions. Refer closely to unit wiring diagram. Refer to unit nameplate for minimum circuit ampacity and maximum fuse size. 1- 230/460/575 volt units are factory wired. For 208V supply, disconnect the orange wire (230V) at control power transformer(s).

- Page 15 This unit is factory charged and should require no further adjustment. If the system requires charge, reclaim the charge, evacuate the system, and add required nameplate charge. NOTE - System charging is not recommended below 60°F (15°C). In temperatures below 60°F (15°C) , the charge must be weighed into the system.
- Page 16 See unit wiring diagram to determine which controls are used on each unit. 1- High Pressure Switch (S4, S7, S28, S96) The compressor circuit is protected by a high pressure switch which cuts out at 410 psig + 10 psig (2825 kPa + 70 kPa) and automatically resets at 300 psig + 20 psig (2069kPa + 138kPa).
- Page 17 LGA/LCA210, 240 & 300S Condenser fans 1 and 2 are energized on a Y1 cooling demand. An increased Y2 demand will energize condenser fans 3 and 4. The C1 (A56) controller de-energizes condenser fan 2 and the C2 (A59) controller de-energizes condenser fan 4 when outdoor temperature drops BEFORE LIGHTING smell all around the appliance area below 55°F (13°C).
- Page 18 1- If using an electromechanical thermostat, set to the lowest setting. 2- Before performing any service, turn off all electrical power to the appliance. 3- Open or remove the heat section access panel. 4- Turn the knob on the gas valve clockwise .
- Page 19 The unit should be inspected once a year by a qualified service technician. Units are equipped with six 24 X 24 X 2" filters. Filters should be checked and replaced when necessary with filters of like kind and size. Take note of air flow direction marking on filter frame when reinstalling filters.
- Page 20 c- Remove burner retaining bracket and lift burners from orifices. d-Clean as necessary and replace burners. Refit retaining brackets. Make sure that burner heads line up correctly. Spark gap on ignition electrode must be properly set. Refer to Heating Adjustment section. Replace access panel.
