4. After connecting, all
gas connections must be checked for leaks
. For this, put
a soapy solution on all gas connections, turn on the gas cylinder manual valve and
watch for bubbles.
Never use an open flame to check for leaks.
Note
: The gas supply system must incorporate a pressure regulator to maintain a
supply pressure of not more than 12” water column and no less than 11” water
column. (Max setting)
.
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 6 to 8 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
evaporator tubing. This will slow the circulation of hydrogen and ammonia gas, or in
severe cases, completely block it, resulting in a loss of cooling. Warranty will not cover
recharge/rebuild if caused by not running the freezer level.
This freezer operates LP Gas (Propane), 110V (Electricity) and 12V DC
Gas Operation
“Start Up” Procedure
After initial installation, servicing, or changing gas cylinders etc., the gas pipes may
contain some air which should be allowed to escape by briefly turning on the freezer.
This will ensure that the flame lights immediately.
· The cylinder be disconnected when the appliance is not in use
· The gas must be turned off at the supply cylinder. Storage of an appliance
indoors is permissible only if the cylinder is disconnected and removed
from the appliance. Cylinders must be stored outdoors out
· The cylinder supply system must be arranged for vapor withdrawal
· If in excess of 1 lb (0.45 kg) of liquid fuel capacity, must include a collar
to protect the cylinder valve
·
D
o not store a spare LP gas cylinder under or near this appliance
· Never fill the cylinder beyond 80 percent full
· If the instructions in l(i) and l(ii) are not followed exactly, a fire causing
death or serious injury may occur;
