LABORATORY REFRIGERATOR-
FREEZER
Installation, Operation and
Maintenance Instructions
INSPECTION
When the equipment is received, all items should be carefully 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 units immediately. If any damage is found, it should be reported to the
carrier at once, and a claim should be filed with the carrier. This equipment has been inspected and
tested at the manufacturing facility and has been crated in accordance with transportation rules and
guidelines. Manufacturer is not responsible for freight loss or damage.
Before connecting the refrigerator to the power supply, let it stand for approximately two hours to
reduce the possibility of malfunctions in the cooling system due to transport handling
INSTALLATION
GENERAL
After the unit crate and crate base have been removed, ensure that the cabinet is level. All four
corners of the unit must rest firmly on a solid floor. The cabinet is equipped with adjustable front
rollers to level the unit. Remove the toe grill as shown below and use a flat bladed screwdriver or
3/8” socket wrench to adjust the front rollers (see the illustration below). Raise the front of the
cabinet enough so that the doors will close freely when opened halfway. The cabinet should slope
¼” to ½” from front to back. Then level the cabinet from side to side.
Note: It is extremely important that the refrigerator be level in order to function properly. If the
refrigerator is not properly leveled during installation, the door may be misaligned and not close or
seal properly causing cooling, frost or moisture problems.

Choose a location near a grounded electrical outlet. Do not install the refrigerator-freezer where the
temperature will drop below 55°F (13°C) or rise above 110°F (43°C). The compressor will not be
able to maintain proper temperatures inside the refrigerator-freezer.
Allow adequate space around the unit for good air circulation. A minimum of 3/8 inch (10 mm)
space on the sides and top and 1 inch (25 mm) space at the back of the refrigerator-freezer is
required for adequate air circulation.
Do not block the toe grille on the lower front of the refrigerator-freezer. Sufficient air circulation is
essential for proper operation of the unit.
Note: The exterior walls of the refrigerator may become quite warm as the compressor works to
transfer heat from the interior. Temperatures as much as 30°F (-1°C) warmer than room
temperature can be expected. It is particular in hotter climates to allow adequate space for air
circulation around the refrigerator.
ELECTRICAL
Check the proposed outlet to be used to insure that the voltage, phase, and current carrying
capacity of the circuit from the electrical panel correspond to the requirements of the cabinet.
NEVER use an extension cord or adapter plug to wire any unit. Refer to the serial tag for all
pertinent electrical information.
The refrigerator-freezer must be plugged into its own 115 volt, 60 Hz, single phase outlet. The
power cord of the refrigerator is equipped with a three-prong grounding plug for protection against
shock hazards. It must be plugged into a properly grounded three-prong receptacle. The
receptacles must be installed in accordance with local codes and ordinances.
If voltage varies by more than 10%, refrigerator performance may be affected. Operating the
refrigerator with insufficient power can damage the compressor.
To prevent the refrigerator from being accidentally turned off, do not plug the unit into an outlet
controlled by a wall switch or pull cord.
Do not pinch, knot or bend the cord in any manner.
Observe all Warning Labels. Disconnect power supply to eliminate injury from electrical
shock or moving parts when servicing equipment.
OPERATION
Cool Down Period
For safe storage of product, allow a minimum of 12 hours for the refrigerator to cool down
completely. The refrigerator will run continuously for the first several hours.
Temperature Control
The temperature control is located inside the refrigerator. When first energizing the refrigeratorfreezer, move the refrigerator and freezer controls to ▼ which is the recommended initial setting.
Adjust the controls after 24 hours if required. Adjust the temperatures gradually. Move the control in
small increments and allow the temperature to stabilize between setting changes.
For colder temperatures, adjust the control knob towards Colder.
For warmer temperatures , adjust the control knob towards Cold.
Turning the refrigerator control will change temperatures in both the refrigerator and the freezer. If
the temperature control is turned to a colder setting, the freezer control may require adjustment to a
warmer setting. Turning the freezer temperature control will change only the freezer temperature.
To maintain required temperatures, a fan circulates air in the refrigerator and freezer compartments.
Do not block cold air vents with product.

TRIM REMOVAL (Full Length Trim Models Only)
In some models, the refrigerator door has a full length trim piece which continues from the bottom of
the handle to the bottom of the door. The top of the trim attaches to the handle bracket (see Figure
1) or fits around the base of the handle (see Figure 2). An adhesive trim lock is positioned
approximately half way down the trim piece. The bottom of the trim is secured by either an adhesive
trim lock or a trim lock with two prongs inserted into a hole on the face of the door.
REMOVE TRIM:
1. Remove the trim by gently pulling the trim lock areas out and away from the door.
2. When the trim is free from the door, slide the trim straight down and away from the base of
the handle. Note: For models with a short handle trim, remove by sliding the trim straight
down and off the handle bracket.

MAINTENANCE
PERIODIC CLEANING
Disconnect the power supply before cleaning the refrigerator.
Beginning with the initial installation, the interior surfaces of the cabinet should be periodically
wiped down with a solution of warm water and baking soda (two tablespoons in one quart of warm
water). This solution will remove any odors from spillage that has occurred. The exterior of the
cabinet should also be cleaned frequently with warm water and a mild liquid detergent. Caution: Do
not use an abrasive or alkaline solution. Do not wash any removable parts in a dishwasher.
Defrosting
CAUTION: Refrigerator-Freezer must be unplugged to avoid electrical hazard from power
source when defrosting the unit.
On upright models with a defrost drain (Figure 1), remove the drain plug on the interior floor of the
freezer by pulling straight out. To access the external drain tube on models with the base panel,
remove the two screws from the base panel. Locate the drain tube near the left center under the
freezer. Place a shallow pan under the drain tube. Defrost water will run out. Check the pan
occasionally to ensure that the drain water does not overflow. A ½ inch garden hose adapter cab be
used to drain the freezer directly into a floor drain. If the model used is not equipped with an
adapter, one can be purchased at most hardware stores. Replace the drain plug when defrosting
and cleaning are complete. If the drain is left unplugged, warm air may enter the freezer.
