CONDITION
See Installation Section for instructions on properly aligning case (alongside other
Case Not Lining
Up cases) and adjusting levelers.
Water Is On The Caution! Water on flooring can cause much damage! Until cause is determined (and
Floor repaired), follow these procedures:


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 Condensate 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° Fahrenheit. For Type 2, maximum conditions
are to be 60% humidity / 80° Fahrenheit. See serial label (at case rear near main
power switch) for NSF® Type of your case.
Check Condensate pan float for proper operation (Heat Rod Condensate System
only).
Check that overflow condensate pan is properly plugged in or connected.
Caution! Condensate pan may be malfunctioning (Electrical Heat Rod Evaporator
system). If so, water will overflow pan and seep onto flooring causing damage! Until
Condensate pan is functioning (or is replaced), follow these procedures:


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:



Caution! Wicking material (if any on your particular hot gas loop system) may be dirty
or worn and need replacement (Hot Gas Condensate system only).


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.
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.
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, Condensate pan should function properly and
water will no longer overflow onto flooring.
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.
