MUST be given to the condenser
coil. The condenser coil must be cleaned at a minimum
of every six months. This can be done with a vacuum
cleaner using a brush attachment, or a stiff brush or whisk
broom. For more information on cleaning, please refer

II. f-TOOL REQUIREMENTS:
For most jobs a standard set of hand tools, a VOM and
AC current tester, along with a temperature tester or ther-
mometer are adequate tools. However, in some cases
the following additional tools may be required as well:

II. g-REFRIGERATION SYSTEM-THEORY OF
OPERATION:
OPERATION:
The refrigeration system is the mechanism whereby heat is
transferred from the cabinet to the outside air. It works under
the principle that the heat moves from hot to cold as it tries to
establish equilibrium.
transferred from the cabinet to the outside air. It works under
the principle that the heat moves from hot to cold as it tries to
establish equilibrium.
The microprocessor control signals a need for heat to be removed
from the cabinet. The compressor begins by compressing the re-
frigerant gas as it is discharged. The high pressure refrigerant
now circulates through the condenser, removing heat from the
refrigerant and condensing it into a liquid. From there the refrig-
erant flows to the filter drier which removes all traces of moisture
and particles from the system.

refrigerant and condensing it into a liquid. From there the refrig-

After the filter drier, the refrigerant passes through a “metering
device”. Traulsen uses a thermostatic expansion valve to regulate
the flow of refrigerant into the evaporator coils.

In the evaporator coil, heat is transferred from the cabinet to the
refrigerant, which changed from a cold liquid to a warm low pres-
sure gas. When the desired cabinet air temperature has been
reached, the microprocessor control shuts off the compressor.

II. h-AIR FLOW REQUIREMENTS:
To assure optimum performance, the condensing unit of your

MUST have an adequate supply of air for cool-
ing purposes. Therefore, the operating location must allow a
minimum of 12” clearance in front of the louvers to allow for
unrestricted air flow to the condensing unit.
