LABORATORY
REFRIGERATORS AND FREEZERS
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 in the manufacturing facility and has been crated in accordance with transportation rules and
guidelines. Manufacturer is not responsible for freight loss or damage.
INSTALLATION
GENERAL
After the unit crate and crate base have been removed, locate the casters or legs if applicable
found inside the cabinet (casters may be pre-installed). Attach the casters or legs to the unit base
by screwing them into the same threaded fittings that were used to secure the crate base to the
cabinet. Insure that the legs or casters are screwed completely into the base.
For shipping purposes, the condensing unit compressor is secured on some of the Laboratory
Freezer models. Remove the spring clips and loosen the mounting bolts prior to operation.
See the label attached to the condensing unit if applicable.
If for some reason the doors are not squared up on the cabinet, the doors can be adjusted. Opening
the door(s) and loosening the screws that hold both the top and bottom hinges to the cabinet can
accomplish this. After adjusting the door so that it is aligned correctly, tighten the screws to securely
hold the hinges in place.
VAPORIZER INSTALLATION
The Extra Low Temperature Freezers require the installation of the condensate vaporizer, which is
shipped inside the unit compartment. The vaporizer should be mounted to the cabinet bottom.
Reference View 1. In lieu of the vaporizer, these units can be plumbed to a floor drain following
local plumbing codes. For those models equipped with a hot gas vaporizer, field installation is not
required.
