TROUBLESHOOTING (GENERAL)
CONDITION TROUBLESHOOTING
Water Is On The Floor Check that the drain trap is free of debris.
Check that the drain hose is correctly positioned over evaporator pan
(or floor drain, for remote units).
Check store conditions. To prevent condensation in Type 1 environments,
maximum conditions are to be 55% humidity / 75 °F. See serial label
(at case rear near main power switch) for your case type.
Check evaporator pan float for proper operation.
Check that evaporator pan is plugged in.
If so, water will overflow
pan and seep onto flooring causing damage! Until evaporator pan is
functioning (or is replaced), the following procedures are recommended:
Use wet-dry vacuum (or mop & bucket) to remove standing water.
Use ‘catch pans’ for water to drain into. Swap out regularly until case
has completely drained.
Check that power to case is
constant. Until power is restored, following these procedures:
Use wet-dry vacuum (or mop & bucket) to remove standing water.
Use ‘catch pans’ for water to drain into. Swap out regularly until
evaporation of case is complete (or until power is restored).
When power to case is restored, evaporator pan should function
properly and water will no longer overflow onto flooring.
Fan Emits Excessive Noise Check that the case is aligned, level and plumb.
Check evaporator fan for cleanliness.
Unplug fan motor; check motor shaft for excessive bearing wear.
Check that fan motor is securely mounted in brackets.
Verify that fan blade is securely mounted to fan motor.
Check that nothing is preventing blade rotation.
Check that the fan shroud is properly secured.
Fans Are Not Working Check that the MAIN power switch (if present) is on.
Check that fans are plugged in to fan shroud.
Check for foreign material obstructing fan performance.
