Koldwave AIRMASTER 3AK - User Manual

GENERAL DESCRIPTION
The Koldwave Airmaster is a portable, air-cooled air
conditioner/zone cooler suitable for indoor/outdoor use.
The Koldwave Airmaster can cool an entire area by
discharging air through its 16" x 12.5" grille. This self-
contained unit is also designed to direct cool air to
specific areas or objects through (optional) dual 6"
diameter snozzles
®
, or a single 10" diameter flexible
duct. This provides precision cooling for heat-sensitive
equipment, production processes and personnel.
The cord-connected Koldwave Airmaster is provided
with heavy-duty casters. The swivel-locking front
casters prevent sliding and stationary rear casters
provide handling ease for conventional relocation. This
unit is completely self-contained with the entire
refrigeration system, electrical components, condenser
and evaporator housed in one attractively-designed,
two-tone enamel finish metal cabinet.
