Table 11 — Condenser Fan Performance — 09XC24 Units
LEGEND
Bhp — Brake Horsepower
ESP — External Static Pressure
NOTES:
1. Units are available with several motor hp options. Refer to Table 2.
2. Static pressure losses for any options or accessories must be
applied to external static pressure before entering the fan perfor-
mance table.
3. Interpolation is permitted; extrapolation is not.
4. Fan performance is based on unit casing, and dry DX (direct
expansion) coil losses at sea level.
SERVICE
Cleaning Condenser Coils
Do not use high-pressure water or air. Damage to fins may result.
Clean coils with a vacuum cleaner, fresh water, compressed air, or
a bristle brush (not wire). Backflush coil to remove debris. Com -
mercial coil cleaners may also be used to help remove grease and
dirt. Steam cleaning is NOT recommended.
Units installed in corrosive environments should be cleaned as
part of a planned maintenance schedule. In this type of applica -
tion, all accumulations of dirt should be cleaned off the coil.
Take care not to get water in the system ducts or unit insulation.
Lubrication
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 start -
ing the unit.
TO CHANGE FAN SPEED
1. Shut off unit power supply. Lock out power supply and tag
disconnect locations.
2. Loosen fan belt by loosening fan motor from mounting
bracket. Do not loosen fan motor mounting bracket from unit.
3. Loosen movable pulley flange setscrew (Fig. 7).
