Accessory lifting kit is only to be used with Small Packaged units which have a composite base pan with molded rigging holds. INSPECTION Prior to initial use, and at monthly intervals, all rigging brackets and straps should be visually inspected for any damage, evidence of wear, structural deformation, or cracks.
2. Place each of the four (4) metal lifting brackets into the rigging holds in the composite pan. 3. Tighten the ratchet strap unit tight. Lifting brackets should be secure in the rigging holds. 4. Attach the clevis or hook of sufficient strength to hole in the lifting bracket (See Fig.

Lifting point should be directly over the center of gravity for the unit. Step 6—Connect Condensate Drain NOTE: When installing condensate drain connection be sure to comply with local codes and restrictions. Models 50GS and 50GX dispose of condensate water through a 3/4 in.
CONFIGURING UNITS FOR DOWNFLOW (VERTICAL) DIS- CHARGE Before performing service or maintenance operations on the system, turn off main power to unit and install lockout tag or electrical shock could result. 1. Open all electrical disconnects and install lockout tag before starting any service work.
5. It is recommended that the unit base insulation around the perimeter of the vertical return-air opening be secured to the unit base with aluminum tape. Applicable local codes may require aluminum tape to prevent exposed fiberglass. 6. Cover both horizontal duct openings with the duct covers from the accessory duct cover kit.
Failure to follow these precautions could result in damage to the unit being installed: 1. Make all electrical connections in accordance with NEC ANSI/NFPA (latest edition) and local electrical codes governing such wiring. In Canada, all electrical connec- tions must be in accordance with CSA standard C22.

When evaluating the refrigerant charge, an indicated adjust- ment to the specified factory charge must always be very minimal. If a substantial adjustment is indicated, an abnormal condition exists somewhere in the cooling system, such as insufficient airflow across either coil or both coils.
inspected at least once each year by a qualified service person. To troubleshoot heating or cooling of units, refer to tables at the back of the book. The following are 50GS Cooling Charging Charts: The following are 50GX Cooling Charging Charts: NOTE TO EQUIPMENT OWNER: Consult your local dealer about the availability of a maintenance contract.
The ability to properly perform maintenance on this equip- ment requires certain expertise, mechanical skills, tools, and equipment. If you do not possess these, do not attempt to perform any maintenance on this equipment other than those procedures recommended in the User’s Manual.
Errors made when reconnecting wires may cause improper and dangerous operation. Label all wires prior to disconnec- tion when servicing. The minimum maintenance requirements for this equipment are as follows: 1. Inspect air filter(s) each month. Clean or replace when necessary.
AIR FILTER Never operate the unit without a suitable air filter in the return-air duct system. Always replace the filter with the same dimensional size and type as originally installed.
c. On all units remove blower assembly from unit. Remove screws securing blower to blower partition and slide assembly out. Be careful not to tear insulation in blower compartment. d. Ensure proper reassembly by marking blower wheel and motor in relation to blower housing before disassembly.
CONDENSER COIL, EVAPORATOR COIL, AND CONDEN- SATE DRAIN PAN Inspect the condenser coil, evaporator coil, and condensate drain pan at least once each year. The coils are easily cleaned when dry; therefore, inspect and clean the coils either before or after each cooling season.
System under pressure. Relieve pressure and recover all refrigerant before system repair or final unit disposal to avoid personal injury or death. Use all service ports and open all flow-control devices, including solenoid valves.
