ELECTRICAL PRECAUTIONS
REAR CLOSE-OFF PANEL
To perform electrical and refrigeration work, remove the
rear closure panel by loosening the sheet metal screws.
Replace when work is complete.
Note: Self-contained Models - Do NOT block the
vent openings on the rear closure panel. These allow
intake and exhaust air for the condensing unit. Vents only
appear on self-contained models.
ELECTRICAL
Self-Contained Model Installation - Medium tem-
perature merchandisers need only to be connected to a
120V / 60 Hz electrical supply. Low temperature mer-
chandisers need to be connected to both a 120V / 60 Hz
and 220V / 60 Hz electrical supply.
CLEANING PRECAUTIONS
WHEN CLEANING:
TO PRESERVE THE ATTRACTIVE FINISH:
Do Use Water and a Mild Detergent for
the Exterior Only!
Do Not Use Abrasives or Steel Wool Scouring Pads
(these will mar the finish)
Do Not Use High Pressure Hoses
Do Not Introduce Water Faster than Waste
Outlet can Drain
Never Use a Cleaning or Sanitizing Solution
that has an OIL BASE (these will dissolve the
butyl sealants) or AMMONIA BASE
(this will corrode the copper components
of the case)
DO NOT USE:
• Mineral oil based solutions, as these will dissolve the
butyl sealants used in the construction of the merchan-
disers.
Connections - All wiring must be in compliance with
NEC and local codes. All electrical connections for the
nonrefrigerated model are to be made in the electrical
panel. Electrical connections for refrigerated models are
made in the electrical box on the back of the case
behind the rear close-off panel.
Field Wiring - Field wiring must be sized for compo-
nents amperes stamped on the serial plate. Actual
ampere draw may be less than specified. Always check
the serial plate.
Post Construction Clean-up - After the first two
weeks of a major store remodel or new store operation,
the grill should be removed and the condensing unit and
condenser face cleaned due to the accumulated dirt and
debris generated during construction.
• Abrasive cleansers and scouring pads, as these will mar
the finish.
DO:
• Remove the product and all loose debris to avoid
clogging the waste outlet.
• Thoroughly clean all surfaces with soap and hot water.
Do NOT use steam or high water pressure hoses
to wash the interior. These will destroy the merchan-
disers’ sealing causing leaks and poor performance.
• Rinse with hot water, but do NOT flood. Never intro-
duce water faster than the waste outlet can remove it.
NOTE: Self-contained Models
The evaporator pan must be monitored for
overflow conditions. Provide drainage if necessary.
After cleaning and rinsing, purge the pan of any standing
water.
• Care should be taken to minimize direct contact
between fan motors and cleaning or rinse water.
