Make sure the freezer and any other high BTU appliances on your line are turned on
when checking the gas pressure. The appliance and its individual shut-off valve must be
disconnected from the gas supply piping system during any pressure testing of that
system at pressures in excess of ½” psig.
If detailed instructions on the installation and connection of the gas supply are required,
contact your dealer or distributor.
Levelling
Ensure the freezer is leveled by using a 2ft level; the operation of this unit uses an
absorption system which requires the appliance to be level in order to operate
effectively.
General Operating Instructions
Importance of Leveling a Freezer
The freezer must be adjusted to a vertical position in both directions. In an absorption
refrigeration system, ammonia is liquefied in the finned condenser coil at the top rear of
the freezer. The liquid ammonia then flows into the evaporator (inside the freezer) and is
exposed to circulating flow of hydrogen gas, which causes the ammonia to evaporate,
creating a cold condition in the freezer.
When starting this freezer, the cooling cycle may require up to 8 to 12 hours of running
time to begin cooling before the cooling unit is fully operational, you can then begin
slowly loading the compartment.
The tubing in the evaporator section is specifically sloped to provide a continuous
movement of liquid ammonia, flowing downward by gravity through this section. If the
freezer is operated when not level, liquid ammonia will accumulate in sections of the
