Time Clock Adjustments:

Setting the correct time of day: Simply rotate the minute hand clockwise until the correct time of day on the outer

dial is aligned with the triangle marker on the inner dial. In referring to the illustration, the correct time of day shown

is 8:00 a.m.

Number of defrosts per day: The time switch is factory set to provide four defrosts per day. If more defrosts are

required, move additional white tabs at the desired time. No more than two consecutive tabs should be set

at any one time. Each white tab constitutes 15 minutes of defrost time. If the four defrost periods provided are

more than necessary, push white tabs back toward the center of the dial.

Fail-Safe feature: The fail-safe of the timer is factory set at 30 minutes. The function of this device is to terminate

the defrost cycle and revert back to the cooling cycle if a system malfunction occurs during defrost. No adjustment

of this device should ever be necessary. Lengthening the fail-safe time will not lengthen the defrost cycle.

Note: The defrost times are factory set at 10:00 a.m., 4:00 p.m., 10:00 p.m., and 4:00 a.m. This setting will provide

adequate defrosting for a normal installation.

Refrigeration Controller

Some Capsule Pak™ Refrigeration Systems are equipped with

conventional temperature thermostats that sense the "cut-in" and

"cut-out" temperatures of the return air to the evaporator coil.

These thermostats are adjustable and require a turn of the dial to

change the interior storage temperature. Note: The control can

be reached through the interior louver for adjustment, with a

6” long shaft flat blade screwdriver. Make adjustments in small

increments until the desired temperature is reached.

Indoor Capsule Pak™ Refrigeration Systems may be equipped

with either a conventional temperature thermostat or an electronic

programmable temperature control. See separate instructions on the

operation of the electronic temperature control.

All outdoor Capsule Pak™ Refrigeration Systems and some indoor

systems employ a "pump-down cycle" which permits the compressor to pump most of the refrigerant from the

evaporator into its receiver after each "on" cycle. In this application, the refrigeration controller regulates the

operation of a solenoid valve in the liquid line. A low-pressure control is installed in the low side of the system that

shuts down the compressor due to low pressure, which results when the solenoid valve closes the liquid line. The

temperature thermostat is adjustable and requires a turn of the dial to change the interior storage temperature.
