General Information
The Koldwave 5AK Series Air Conditioners
are portable, air-cooled air conditioners/zone
coolers suitable for indoor/outdoor use. The
Koldwave air-conditioner cools an entire
area by discharging air through its supply
grille. This self-contained unit is also
designed to direct cool air to specific areas
or objects through (optional) flexible
snozzles®. This provides precision cooling
for heat-sensitive equipment, production
processes and personnel.
Each unit is completely self-contained with
the entire refrigeration system, electrical
components, condenser and evaporator
housed in one cabinet. The Koldwave unit
is provided with heavy-duty casters. Two
swivel-locking casters prevent sliding; two
stationary casters provide handling ease for
relocation.

Installation Instructions
Electrical Requirements
Check the power supply to make certain it is
within 10% of the voltage listed on the data
plate located on the back of the unit.
Operating the unit on improper voltage
will void the product warranty.
Refer to the Rating Plate for voltage and
current information.
Each unit should have a dedicated circuit
breaker.

5AK65 240/1/60 Field wired240/3/60
460/3/60
Extension cords used with the Koldwave
units should match the plug configuration of
the service cord provided on the unit. The
extension cord must be equipped with an
equipment grounding conductor, a
grounding type attachment plug, and a
grounding type attachment connector. The
cord must also have a rating suitable for the
voltage and ampacity.
The Koldwave 5AK65 is a field wired unit
which requires a field supplied electrical
service disconnect. Check the unit
nameplate for the correct voltage, phase and
maximum fuse size for the electrical service
for the unit. A high voltage terminal block is
provided in the unit’s control box for the
electrical connection. Route the electrical
power leads through the electrical knockouts
provided on either side of the control box.
Install the required electrical service wiring
in accordance with all applicable codes.
IMPORTANT: Following the installation
and preventative maintenance instructions
can extend the length of service you
receive from your Koldwave unit.
