TROUBLESHOOTING
Water On Floor
Caution!
Water on flooring can cause much damage! Until cause is determined
(and repaired), follow 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 case has
completely drained.
Note:
See
Drain, Hose and Bracket Placement Illustrations
sheet in this manual for
views of different evaporator systems used in display cases.
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 NSF® Type 1 environments,
maximum conditions are to be 55% humidity / 75° Fahrenheit. For Type 2, maximum
conditions are to be 55% humidity / 80° Fahrenheit. See serial label (at case rear
near main power switch) for Type of your case.
Check evaporator pan float for proper operation (Heat Rod Evaporator System only).
Check that evaporator pan is properly plugged in or connected.
Caution!
Overflow evaporator pan may be malfunctioning (electrical heat rod
evaporator system). If so, water will overflow pan and seep onto flooring causing
damage! Until evaporator pan is functioning (or is replaced), follow 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 case has
completely drained.
Caution!
Disruption of power can cause water to overflow pan and seep onto
flooring causing damage! Check that power to case is constant. Until power is
restored, follow these procedures:
Use wet-dry vacuum (or mop & bucket) to remove standing water.
Use ‘catch pans’ for water to drainage. 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.
Caution!
Wicking material (if any on your particular hot gas loop system) may
be dirty or worn and need replacement (Hot Gas Evaporator system only).
Slide refrigeration system out from under unit.
After refrigeration system has been carefully slid out from under unit, replace
wicking material with new. If wicking material is not available, contact Structural
Concepts®. See toll-free number at last page of this operating manual.
