START-UP

To prevent personal injury, be sure wire fan guards are secured in place over each fan discharge (or that fans are ducted) before starting the unit.

Complete Unit Start-Up Checklist on page CL-1 prior to start-up of this system.

System Evacuation and Dehydration Ð Refer to GTAC II, Module 4, ``Dehydration for Proper Evacuation and Dehydration Techniques.''

Charging Procedure Ð BEFORE CHARGING THE SYSTEM, INSTALL OR REPLACE THE FILTER DRI- ER(S) CONNECTED TO THE LIQUID LINE IN THE INDOOR UNIT TO PREVENT CONTAMINATION WITHIN THE SYSTEM. Refer to GTAC II, Module 5 ``Charging, Recovery, Recycling, and Reclamation'' for proper charging techniques.

Check Operation of Condenser Fan Motor Con- trols and Rotation of Fans Ð Rotation should be clockwise as viewed from belt access panel.

IMPORTANT: Check for proper fan rotation. If rota- tion needs to be reversed, disconnect main power sup- ply and switch any 2 leads at the load side of the dis- connect switch.

Adjust Fan Speed Ð The 09BY units are belt-driven condenser units and allow for a wide range of inlet static and condenser air¯ow requirements. It may be necessary to ad- just the condenser air¯ow to account for these inlet condi- tions. Inadequate air¯ow will result in poor unit performance and possible nuisance tripping of high-pressure switches.

If an air¯ow is not speci®ed, use the nominal air¯ow from Table 2 and adjust the fan speed to compensate for actual job conditions. Use Table 5 to determine proper fan speed. If the unit trips on high pressure due to high condensing tem- perature, then it may be necessary to increase the fan speed and condenser air¯ow.

SERVICE

Cleaning Condenser Coils

Do not use high-pressure water or air. Damage to ®ns may result.

Clean coils with a vacuum cleaner, fresh water, com- pressed air, or a bristle brush (not wire). Back¯ush coil to remove debris. Commercial coil cleaners may also be used to help remove grease and dirt. Steam cleaning is NOT rec- ommended. Units installed in corrosive environments should be cleaned as part of a planned maintenance schedule. In this type of application, all accumulations of dirt should be cleaned off the coil.

Lubrication Ð Fan motors have permanently lubricated bearings.

Condenser Fan Adjustment

To prevent personal injury, be sure wire fan guards are secured in place over each fan discharge (or that fans are ducted) before starting the unit.

TO CHANGE FAN SPEED

1.Shut off unit power supply.

2.Loosen fan belt by loosening fan motor from mounting bracket. Do not loosen fan motor mounting bracket from unit.

3.Loosen movable pulley ¯ange setscrew (Fig. 12).

4.Screw movable ¯ange toward ®xed ¯ange to increase fan speed and away from ®xed ¯ange to decrease speed. In- creasing fan speed increases load on motor. Do not ex- ceed maximum allowable fan speed (Table 2) or motor full load amps indicated on motor nameplate and in Table 4.

5.Set movable ¯ange setscrew at nearest ¯at of pulley hub and tighten setscrew.

6.Check pulley alignment and belt tension adjustment as described below.

7.Check fan operation. Repeat above procedure as required.

PULLEYALIGNMENT Ð Shut off unit power supply. Loosen fan motor pulley setscrews and slide fan pulley along fan shaft. Make angular alignment by loosening motor from mount- ing bracket (see Fig. 12). Check alignment with a straightedge.

BELT TENSION ADJUSTMENT Ð Shut off unit power sup- ply. Loosen fan motor mounting plate bolts. Do not loosen motor mounting bracket from unit. Move fan motor mount- ing plate until proper belt tension is achieved (approxi- mately 1¤2-in. de¯ection with 8-lb tension at midpoint of belt span).
