GLYCERIN WELL ASSEMBLY
Important: For accurate product temperature
reading, the product-sensing bulb must be
immersed in glycerin solution contained in the
provided well.
One or two glycerin wells, along with a six-ounce
container, or containers, of glycerin are furnished
with each model. The purpose of the glycerin is to
simulate the product stored in the refrigerator or
freezer. The glycerin temperature reflects the
product's temperature during normal operation.
After the unit is put into operation, remove the
stopper at the top of the glycerin well. Check to
make sure that the temperature indicating or alarm
sensing bulb is positioned inside and at the bottom
of the glycerin well. Add the six ounces of glycerin
that has been provided into the glycerin well.
Reinstall the stopper to the top of the glycerin well.
MAINTENANCE
PERIODIC CLEANING
Beginning with the initial installation, the interior surfaces of the cabinet should be periodically
wiped down with a solution of warm water and baking soda. This solution will remove any odors
from spillage that has occurred. The exterior of the cabinet should also be cleaned frequently with a
commercial grade of glass cleaner. Caution: Do not use an abrasive or alkaline solution.
Monthly cleaning of the condenser will aid the heat transfer characteristics of the refrigeration
system and increase its efficiency. Dust, dirt, and lint will tend to accumulate on the fins of the
condensing unit. This obstruction will affect the flow of air through the condenser, thereby lowering
the efficiency of the system. A stiff bristled brush can be used to loosen these particles that are
attached to the fins so that they may be removed with a vacuum cleaner. Do not use a wire brush
for cleaning the condenser. Important: Failure to keep the condenser coil clean and clear of
obstructions could result in temperature loss and damage to the compressor. Do not use a
wire brush to clean the condenser.
All moving parts have been permanently lubricated and will generally require no maintenance.
