Nor-Lake General Purpose Lab Freezer - Manual

LABORATORY 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 freezer 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, use a carpenter’s level to level the freezer
from front-to-back. Adjust the plastic leveling feet in front ½ bubble higher to ensure that the door
closes easily when left halfway open.
Note: It is extremely important that the freezer be level in order to function properly. If the freezer is
not properly leveled during installation, the door may be misaligned and not close or seal properly
causing cooling, frost or moisture problems. See the illustration below.

Choose a location near a grounded electrical outlet. For the most efficient operation, the freezer
should be located where the temperatures will
not exceed 110°F (43°C). Temperatures of
32°F (0°C) and below will not affect freezer
operation. Additional compressor heaters are
not recommended.
Allow adequate space around the unit for good
air circulation. A minimum of 3 inches (75 mm)
space on all sides of the freezer is required for
adequate air circulation.
Note: The exterior walls of the freezer 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 particularly
important in hotter climates to allow adequate
space for air circulation around the freezer.
