Inspect the drain pan and condensate drain line when inspecting the coils. Clean the drain pan and condensate drain by removing all foreign matter
from the pan. Flush the pan and drain tube with clear water. Do not splash water on the insulation, motor, wiring, or air filter(s). If the drain tube
is restricted, clear it with a ''plumbers snake'' or similar probe device. Ensure that the auxiliary drain port above the drain tube is also clear.
PROCEDURE 5—OUTDOOR FAN
CAUTION: UNIT OPERATIONAL HAZARD
Failure to follow this caution may result in damage to unit components.
Keep the Outdoor fan free from all obstructions to ensure proper cooling operation. Never place articles on top of the unit.
1. Shut off unit power supply and install lockout tag.
2. Remove outdoor-fan assembly (grille, motor, motor cover, and fan) by removing screws and flipping assembly onto unit top cover.
3. Loosen fan hub setscrews.
4. Adjust fan height as shown in Fig. 12 or 13.
5. Tighten setscrews.
6. Replace outdoor-fan assembly.
PROCEDURE 6—ELECTRICAL CONTROLS AND WIRING
Inspect and check the electrical controls and wiring annually. Be sure to turn off the electrical power to the unit and install lockout tag.
Remove the top panel to locate all the electrical controls and wiring. Check all electrical connections for tightness. Tighten all screw connections.
If any smoky or burned connections are noticed, disassemble the connection, clean all the parts, restrip the wire end and reassemble the connection
properly and securely.
Check to ensure no wires are touching refrigerant tubing or sharp sheet metal edges. Move and secure wires to isolate from tubing and sheet metal
edges.
After inspecting the electrical controls and wiring, replace all the panels. Start the unit, and observe at least one complete cooling cycle to ensure
proper operation. If discrepancies are observed in operating cycle, or if a suspected malfunction has occurred, check each electrical component
with the proper electrical instrumentation. Refer to the unit wiring label when making these checkouts.
NOTE: Refer to the Sequence of Operation section, as an aid in determining proper control operation.
PROCEDURE 7—REFRIGERANT CIRCUIT
Inspect all refrigerant tubing connections and the unit base for oil accumulations annually. Detecting oil generally indicates a refrigerant leak.
