Connecting Power Pak To Trunk Housing - Perlick 4410QC-2 Installation And Operation Instruction Manual

4400QC SERIES POWER PAKS - AIR COOLED
- INSTALLATION
ALL MODELS
• Determine the ideal placement of the Power Pak.
Locate the connection point to the truck housing
and place the Power Pak as close to this point as
possible. NOTE: If the Power Pak is to be located
on top of the walk-in cooler, it is imperative
that proper ventilation is provided to prevent
system failure due to overheating. Inadequate
ventilation will void warranty.
• Place the Power Pak and Ensure that it is level to
provide proper overflow protection. REMINDER:
Allow a minimum of six inches of clearance
on the louvered ends of the cabinet for proper
airflow. Allow accessibility room on the top of
the cabinet for serviceability.
• Remove the top panels (2).
• Ensure Power Switches for Condensing Unit and
Pump(s) are in the OFF position. Make the electrical
connections per their illustrations. NOTE: Electrical
circuit should be a dedicated circuit for use only
with the Power Pak. The circuit should be sized in
accordance with the electrical requirements of each
unit as well as in compliance with all National and
Local Codes.
• Plumb overflow port to a suitable reservoir/drain.
CONNECTING POWER PAK TO
TRUNK HOUSING
4400QC Series Power Paks require rigid fittings with
a minimum pressure rating of 150 psig. Use Coolant
Connector Kit C23015 to connect Power Pak to
Trunk Housing.
■ Inspect pump outlet port for debris. Insert barbed
fitting into pump outlet port.
■ Inspect Glycol Return Manifold inlet for debris.
Insert barbed fitting into return manifold inlet port.
■ Cut supplied coolant tubing, to required length to
reach from Power Pak to Trunk Housing connection
point.
■ Cut tubular insulation sleeve, in half and install over
previously cut coolant tubing.
■ Take oetiker clamps, and install over coolant
tubing ends.
■ Push coolant lines, one each over pump outlet
Perlick is committed to continuous improvement. Therefore, we reserve the right to change specifications without prior notice
barbed fitting and return manifold barbed fitting.
■ Position oetikers over barbed fitting and clamp
securely.
■ Slide tubular insulation sleeves tightly against
connection points. Use insulation tape as
necessary to ensure an air tight seal to prevent
excessive heat gain or condensation problems.
■ Drill a 3 1/2 " diameter hole in walk-in cooler to
accommodate coolant lines.
■ Install insulating donuts over hole (both inside
and outside of cooler walls).
■ Slide large insulation sleeve, over remaining coolant
tubing exposed to warm air conditions including
inside walk-in cooler from Power Pak to Trunk
Housing connection point. Seal and tape all seams
to prevent excessive heat gain or condensation
problems.
■ Slide coolant lines through 3 1/2 " donut hole
previously cut in walk-in cooler wall.
■ Position Trunk Housing coolant lines and Coolant
Connector kit lines in horizontal position, to alleviate
condensation runoff into Trunk Housing.
■ Cut Trunk Housing coolant lines with tubing cutter
to ensure clean burr free ends.
■ Take oetiker clamps and install over coolant
connector kit tubing ends.
■ Slide coolant connector kit tubing over the
trunk housing coolant lines and secure using
above oetikers.
■ Complete the insulation process by ensuring that
all coolant lines are well insulated including all
seams to prevent excessive condensation and
heat gain.
■ Seal donut hole to ensure an air tight seal to prevent
walk-in cooler problems as well as condensation.
