Installation, Operation and

Maintenance Instructions

INSPECTION

When the equipment is received, all items should be checked against the bill of lading to
insure all crates and cartons have been received. All units should be inspected for concealed
damage by uncrating the unit immediately. If any damage is found, it should be reported to
the carrier at once, and a claim should be filed with the carrier. The equipment has been
inspected and tested in the Nor-Lake manufacturing facility and has been crated in
accordance with transportation rules and guidelines. The manufacturer is not responsible for
freight loss or damage.

INSTALLATION

CASTERS

After the packaging and shipping base have been removed, locate the casters found inside
the cabinet. Attach the casters to the bottom of the cabinet using the bolts found installed in
the base (four bolts /caster). The casters with the brakes should be installed in the front of
the cabinet. Do not operate the unit without casters or legs installed.

CLEANING

The exterior of the cabinet and doors may have been protected with a plastic covering. Peel
this protective covering before installation. After removing the covering, clean the interior and
exterior surfaces of the unit with soap and water and rinse with clean water. Dry with a soft
cloth. Do not use chlorinated cleaners on the cabinet as they can cause corrosion. Do not
use abrasive cleaners or pads as they can scratch the surfaces.

DOOR ALIGNMENT

If the doors have come out of alignment during transit, they can be adjusted. This is
accomplished by losing the screws on the door hinges, adjust the door so it is aligned
properly and tighten the hinge screws. Note: the door on model ZF071 is field-reversible.
Should you require instructions for reversing the door, please contact Nor-Lake service and
request the instructions (PN 150566).

SHELVES

The shelves and shelf clips are packaged inside the cabinet. Install the shelf clips on the
pilasters inside the unit and set the shelves on the shelf clips. The shelves are adjustable in
½” increments.

LOCATION

The refrigeration system located in the back of the unit requires space for proper operation.
In order to assure proper airflow, allow a minimum of four (4) inches on ZR cabinets and six
(6) inches on ZF cabinets of clear space on the sides and back of the cabinet.

Do not locate the unit next to heat generating equipment or in direct sunlight. Improper
installation will void the warranty.

Confirm that the proposed electrical outlet has the correct voltage, frequency and current
carrying capacity for the requirements of the unit. Refer to the serial plate located on the
inside left wall of the cabinet for electrical information. The unit should be isolated on a
circuit. Do not use an extension cord to get power to the unit. Improper electrical
installations will void the warranty.

OPERATION

The lower storage section of these cabinets employ a forced air cooling system with
automatic defrost. No plumbing is required for condensate water. Cooling in this section
should start once the cabinet is connected to power. There is a temperature control located
on the interior back wall. Turn the temperature control knob clockwise for cooler cabinet
temperatures and counterclockwise for warmer cabinet temperatures. Do not block the
airflow at the back of the cabinet with product as that will affect the cabinet temperature.
There is a cabinet temperature indicator located behind the right hand door. Refrigerator
(ZR) cabinets have an operating temperature of 32 to 41 degrees F and the freezer (ZF)
cabinets have an operating temperature o f -10 to +10 degrees F.

The rail section operates independently of the lower storage section. There is an on/off
switch for the rail on the front right side of the rail (marked Rail Only). Use this switch to turn
off the rail when not in use or to defrost the cold wall rail section. The temperature control for
the rail is located behind the right side panel on the rail. To adjust the temperature of the rail,
remove the rail end panel and locate the rail temperature control. Turn the temperature
control clockwise for cooler rail temperatures and counterclockwise for warmer rail
temperatures. Allow several hours for rail temperature adjustments. Product should be
removed from the rail during extended periods of non use. The rail section is designed to
keep products cool not pull them down so product loaded in the rail should be down to
temperature prior to putting it in the rail section. The rail section will build up ice on the walls
and should be shut off to defrost. Do not operate the rail unless it is filled completely with jars
to minimize ice buildup.

MAINTENANCE

Observe all warning labels. Disconnect the power supply to the units to eliminate
electrical shock and injury from moving parts when serving the unit.

CLEANING

Beginning with the initial installation, the interior surfaces of the cabinet and rail should be
periodically wiped down with a solution of warm water and baking soda. This solution will
remove any odors from spillage that has occurred. The exterior of the cabinet should also be
cleaned frequently with a commercial stainless steel cleaner, glass cleaner or mild soap
solution. Do not use chlorinated cleaners on the surfaces. Do not use abrasive pads or
cleaners as they will scratch the surface.

The door gaskets should be cleaned with a mild soap solution to extend their life.
The shelving can be cleaned in a sink with a mild soap solution and a soft bris tl ed brus h.

CONDENSER COIL

Prior to cleaning the condenser coil, disconnect the unit from power. Periodic cleaning of the
condenser coil will aid the heat transfer of the system and improve its efficiency. Cleaning is
recommended a minimum of every six months. The condenser coil is located behind the
back panel. Remove the back panel and locate the finned condenser coil. Use a soft bristled
brush to remove any collected dirt or debris on the coil. Use a vacuum cleaner or
compressed air to remove the loosened particles. Replace the back panel and reconnect the
power. Failure to clean the condenser coil can lead to performance loss and compressor
failure.

SERVICE

Any correspondence pertaining to these cabinets should be directed to the Service
Department. Be sure to include the cabinet model and serial number with any
correspondence.
