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

Insure that the cabinet crate is on a smooth level surface. While supporting the cabinet cut the
banding straps that secure the cabinet to the crate base. Check and confirm that the casters/legs
are screwed completely and tightly into the cabinet base. Be aware that the cabinet is top heavy
and carefully remove the cabinet from the crate base.

If the condensing unit compressor is semi-hermetic, it is secured for shipping on the 1 door and 2
door models. Remove the spring clips and loosen the mounting bolts prior to operation. See
the label attached to the condensing unit. If the condensing unit compressor is hermetically sealed,
no spring clips or mounting bolts are present.

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 Plasma Freezers require the installation of the condensate vaporizer, which is shipped inside
the unit compartment. The vaporizer should be mounted to the cabinet bottom. See View 1. In lieu
of the vaporizer, these units can be plumbed to a floor drain following local plumbing codes.

Note: Disconnect power
prior to installation.

1. Connect the power cord
to the vaporizer and
place it in the vaporizer
bracket.

2. Attach the vaporizer to
the unit using the four
screws as shown. Make
sure the plastic drain
tube is in the vaporizer
pan.

LOCATION

The refrigeration system located at the top of the cabinet requires free air access for proper
operation. Allow a minimum four-inch clearance on the top, rear, and sides of the cabinet. The
cabinet should also be leveled when it is placed in its permanent location.

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 to wire any unit. On permanently connected units, those not
furnished with a plug-in service cord, all inter-wiring between the electrical panel and the unit must
be done in accordance with the National Electric Code and all state and local codes. See serial tag
for electrical data.

2-10VDC temperature retransmit is standard on some models, optional on others. See the
following pages for details and also see the controller programming manual for configuration details.
An optional 4-20mA temperature retransmit is also available.

2

Observe all Warning Labels. Disconnect power supply to eliminate injury from electrical
shock or moving parts when servicing equipment.
