Do Not Install the Vented Panels of the
self-contained model against a wall or
other storage fi xture.
Located in the lower front and rear of the self-contained
models are vented panels. These panels allow air circulation
to the condensing unit. Blocking or restricting air circulation
through these panels can cause poor performance and
damage the refrigeration system.
Exterior Loading
These models have not been structurally designed to support
excessive external loading.
Do not walk on their tops;
This could cause serious personal injury and damage to
the fi xture.
Leveling
A LEVEL CASE IS NECESSARY TO INSURE PROPER
OPERATION AND WATER DRAINAGE.
Note: To avoid removing concrete fl ooring, begin
lineup leveling from the highest point of the store
fl oor.
Store Conditions
• Case is designed to operate at temperatures at either
75°F at at 55% relative humidity or 80°F at 55% relative
humidity. Case must be kept in that environment to
ensure case performance and product safety.
• Do not position the case near an HVAC vent.
• Do not position the case near an entrance door. Out-
side ambient conditions may have an adverse aff ect on
the refrigeration performance, a minimum of 15’ clear-
ance is required from doors.
• Do not position the case tight against a ceiling or soffi t.
A minimum clearance 10” above the unit is required for
proper compressor discharge air fl ow.
• Do not block case front panel vent (supplies critical
intake air fl ow to the compressor)
BEFORE SERVICING
ALWAYS DISCONNECT ELECTRICAL
POWER AT THE MAIN DISCONNECT
WHEN SERVICING OR REPLACING ANY
ELECTRICAL COMPONENT.
This includes (but not limited to) Fans, Heater
Thermostats, and Lights .
Uncrating the Stand
Place the fixture as close to its permanent position as
possible. Remove the top of the crate. Detach the walls from
each other and remove from the skid. Unbolt the case from
the skid. The fi xture can now be lifted off the crate skid.
Lift
only at base of stand!
It is the contractor’s responsibility to install
case(s) according to local construction and
health codes.

Condensate Pan Setup and Maintaintence
Setup:
There are two condensate evaporator pans on this unit. The drain pipes from the case feed into the “Primary Condensate
Pan”. This condensate pan will turn on when the fl oat switch level is triggered. If the volume of water is above the capac-
ity of this pan, excess water will fl ow into the “Secondary Condensate Pan”. Both the Primary and Secondary condensate
pans are placed into a metal receiver. The metal receiver is there to collect excess water that may overspill in case of (a)
failure of the condensate pans or (b) store conditions being above design specifi cation causing more condensate water to
be formed than expected.
Maintaintence:
Care must be taken to ensure that the condensate pans operate properly at the store. These units are designed to oper-
ate at either 75°F ambient and 55% RH or 80°F ambient and 55% RH. If stores are operating above this condition, case
performance will be severely affected. If such a condition is noted, the metal receiver under the condensate pans must be
checked periodically to see if excess water is being collected. If water has accumulated, water must be siphoned out of
the receiver. Care must be taken while performing this step. Unit power should be shut off for electrical safety. Once water
has been removed and metal receiver is dried out, unit power can be turned back on.
