conditions are to be at 55% maximum humidity and
maximum temperatures of 75 °F (24 °C).
For Type 2 Conditions: Ambient conditions are to be
at 60% maximum humidity and maximum
temperatures of 80 °F (27 °C).
This equipment MUST be installed in compliance with
all applicable NEC, federal, state and local
electrical and plumbing codes.
If unsure if unit is for Type 1 or Type 2 environments,
see identifier tag. Location varies depending upon
model.

OVERVIEW / CONDITIONS / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING - PAGE 2 of 2
PRECAUTIONS
This sheet contains important precautions to prevent
damage to unit or merchandise.
Please read carefully!
See previous page for specifics on OVERVIEW,
CONDITION TYPE, COMPLIANCE and WARNINGS.
CAUTION! LAMP REPLACEMENT GUIDELINES
Fluorescent lamps have been treated to resist breakage and
CAUTION
must be replaced with similarly treated lamps.
If LED lamps are used, they must reflect specific size, shape and overall
design. Any replacements must meet factory specifications.
CAUTION! GFCI BREAKER USE REQUIREMENT
If N.E.C. (National Electric Code) or your local code
requires GFCI (Ground Fault Circuit Interrupter) protection,
you MUST use a GFCI breaker in lieu of a GFCI receptacle.
WIRING DIAGRAM
Each case has its own wiring diagram folded and in its
own packet.
Wiring diagram placement may vary; it may be placed
near ballast box, field wiring box, raceway cover, or
other related location.
CAUTION
CAUTION! POWER CORD AND PLUG MAINTENANCE
Risk of electric shock. If cord or plug becomes damaged,
replace only with cord and plug of same type.
CAUTION! ADVERSE CONDITIONS / SPACING ISSUES
Performance issues caused by adverse conditions are NOT warranted.
End panels must be tightly joined or kept at least 6-inches away from
any structure to prevent condensation.
Unit must be kept at least 15-feet from exterior doors, overhead HVAC
vents or any air curtain disruption to maintain proper temperatures.
Unit must not be exposed to direct sunlight or any heat source
(ovens, fryers, etc.).
Tile floors, low ceilings or small rooms increase noise level. Whisper
Cool compressor blankets or remote units resolve noise level issues.
For Self-Contained Units: Keep at least 4” front air intake / 4” rear air
discharge clearance.
CAUTION! CHECK HOT GAS EVAPORATOR PAN POSITION AND PLUG
Water on flooring can cause extensive damage!
Hot gas evap. pan MUST BE positioned directly under condensate drain.
Overflow evap. pan plug MUST BE securely plugged into receptacle.
Before powering up unit, check the following:
