4400 SERIES POWER PAKS STARTUP
Operation/Installation Manual
SYSTEM START-UP
Use only Perlick Approved Coolant Solution, #63299-
1, all other solutions and mixtures will void the Perlick
warranty. The Coolant Solution has been pre-mixed for
optimum performance and wear protection. The Power
Pak resevoir holds approximately 1.75 gallons of solu-
tion. It takes approximately 1 gallon of Coolant Solution
to fill every 60 feet of Perlick Trunk Housing.
• Never operate the circulating pumps without coolant
in the resevoir.
• Fill Power Pak resevoir with Perlick Coolant Solution.
• Turn condensing unit switch and pump switch to the
ON position. Coolant solution level will begin to drop
in resevoir.
• Continue adding Perlick Coolant Solution until no
air bubbles are apparent from the Coolant return
line. NOTE: Never allow for the Coolant level in
the resevoir to drop below the heat exchanger
tube inlet. Allowing the level to drop below the
inlet will allow air into the lines.
• Fill Power Pak reservoir until both the return
line fitting port and the overflow tube port are
submersed under Coolant Solution. Watch return
line fitting port for additional Coolant Solution may
need to be added.
• Thoroughly check all field connection points for
leaks.
• Monitor Power Pak Temperature read-out to ensure
Power Pak is working properly. Dependent on
length of trunk housing run(s) and surrounding
ambient conditions, these factors will determine
how long it takes for the Power Pak to cut-out on
the temperature control.
DIGITAL TEMPERATURE CONTROLLER
The 4400 Series Power Pak comes equipped with
a Factory Programmed Electronic Thermostat with
display. The Thermostat has numerous factory
settings, which should never be adjusted or tampered
with to ensure proper operation of the Power Pak. The
Thermostat has been factory programmed to cut-out at
30°F with a hysteresis/differential of 4°F.
