Unit Installation
A. Receiving Shipment
Examine the exterior of the shipping crate for signs of abuse. Partially remove the crate and examine the
cabinet for any possible concealed damages. If no damages are evident replace the crate. If the unit is
damaged note on the delivery slip or bill of lading and signed to that effect. A claim must be filed immediately
against the carrier indicating the extent and estimated cost of damage occurred.
B. Locating Your New Unit
The following conditions should be considered when selecting a location for your unit:
1. Floor and Countertop load - The area on which the unit will rest must be free of vibration and strong enough
to support the weight of the unit plus the maximum product load.
2. Clearance - There must be sufficient clearance on all sides of the unit to allow for efficient airflow.
3. Ventilation - The air cooled self contained unit requires a sufficient amount of cool clean air. Avoid placing
the unit near heat generating equipment such as ovens, ranges, heaters, fryers, steam kettles, etc. and
out of direct sunlight. Avoid locating the make table in an unheated room or where the room temperature
may drop below 13°C or above 32°C.
C. Electrical Supply
A properly wired and grounded outlet is required to assure proper operation. Please consult the data plate on
the compressor for correct electrical requirements. Supply voltage and amperage requirements are located on
the model and serial number tag.
Unit Operation
This unit operates with an electronic control which is factory set for optimal performance and then locked so no
adjustments are necessary. The numerical led display indicates the air temperature in the cabinet. If the
control senses an abnormality it will begin to display an error message which in some cases will alternate with
the temperature display. the error message “HA” (High Alarm) denotes that the temperature in the refrigerator
has been too high for too long. This condition could be casued by an open door, dirty coils, or a refrigeration
system problem. As soon as the temperature is back within the limits this alarm will end. The following table
lists the possible error codes and the suggested actions:
