Koldwave AIRMASTER 2AK1011 Bedienungsanleitung
GENERAL DESCRIPTION
The Koldwave Airmaster is a portable air-cooled zone
cooler which directs cool air to specific areas or
objects through four, adjustable, four-way grilles. Many
small computer and telephone rooms, tanning bed
rooms, laboratories, factories, and numerous areas
can be cooled by its indicated cooling capacity.The
Koldwave Airmaster can also be used for back-up
cooling or as an emergency stand-by unit.
The cord-connected Koldwave Airmaster is provided
with heavy-duty casters.The swivel casters provide
handling ease for convenient relocation.This unit is
completely self-contained with the entire refrigeration
system, electrical components, condenser and
evaporator housed in an attractively-designed, painted
metal cabinet.

KOLDWAVE 2AK (AIRMASTER)
CABINET
The Koldwave Airmaster cabinet is constructed of 20
gauge, cold rolled steel with painted steel finish for
corrosion protection. It is lined with thermal and sound
absorbent insulation material in the discharge area
and vibration dampening on all panels.
SAFETY ENGINEERED
In addition to the rotary compressor’s overload
protection, Koldwave Airmaster incorporated, within
the refrigeration system a manual reset high pressure
switch for maximum safety of the compressor. The cut-
out pressure setting is 375 ±10 psig. In the event that
the high pressure switch setting is exceeded, the
compressor and condenser fan operation will cease.
The compressor and condenser fan can be restarted
by depressing the “reset” button located on the back
panel of the unit.The high pressure switch capillary
line screws onto an access valve on the refrigeration
discharge line to make it possible to remove or replace
a defective control without disturbing the refrigeration
system.The unit also employs an automatic reset
freeze control, located on top of condenser coil, to turn
the entire unit off at low ambients and defrost the
evaporator coil for approximately five minutes.
NOTE:Wait two minutes before restarting unit after
tripping by one of the safety features.

4. Service Cord
RELIABLE CONTROLS
The self-contained unit maintains the desired amount
of cooling, which can be selected by adjusting the
thermostat to warmer or cooler.The thermostat
sensing bulb is in the return air stream behind the
louvered return air grille and return air filter.The range
of the thermostat is from 65-100°with a differential of
±3°F.
The three-position, mode selector rocker switch,
located in the front panel, has three functions:
1. To provide fan only operation when depressed to
the right.
2. To turn the unit off when set in the center position.
3. To activate the cooling mode when depressed to
the left.
The blue colored light above the thermostat indicates
the thermostat is calling for cooling mode operation.
Compressor may or may not be on, depending on the
thermostat setting. The red, “tank full” warning light
indicates condensate tank is full and needs to be
emptied.The two-position, fan-speed rocker switch,
located below the mode selector switch, provides high
fan speed when depressed to the right and low speed
when depressed to the left.

DISCHARGE AIR GRILLES
The Koldwave Airmaster is equipped with (4) 5" x 5",
four-way adjustable, plastic grilles, located in the upper
front panel, enabling a variety of air flow possibilities.
Pull out each black grille (approximately 3/4") and
rotate to the desired position. Release the grille and
allow it to return to the set position within the cabinet.
By this means, air flow can be positioned in any four
directions.
CONDENSATE RESERVOIRTANK
The Koldwave Airmaster incorporates a 5.0 gallon
capacity, polyethylene, condensate drain tank, located
in the lower, front section of the unit. A high water cut-
out switch is used to stop the entire unit’s operation
automatically when the tank is full of water. An
adjustment screw is provided to set the desired
condensate level where the unit cuts out.Turn screw
clockwise to lower water level and thus decrease the
tank’s weight for emptying.To prevent spillage, the
tank is equipped with a cap, which is chained to the
top of the tank, and a vent for easy drainage.
CAUTION:Turn unit off before emptying tank when
tank light is illuminated.
SERVICE CORD
The six foot service cord employed in Model
2AK1411M will not fit in the standard household
receptacle. Required is a 20A-125 volt NEMA 5-20
receptacle.Model 2AK1011 uses a standard 15 amp
plug.

AIR FILTERS
The Koldwave Airmaster employs two, 1/2" thick,
washable aluminum mesh air filters, located behind
the louvered front (evaporator) panel and beneath the
back (condenser) panel.The evaporator filter can be
easily removed and cleaned; just pull the filter end cap
at the bottom of filter and slide out.The condenser
filter is removed by lifting the tab at bottom of filter,
then pulling toward you and down.
GENERAL AIRFLOW PATTERNS
Condenser air is drawn in through the lower rear
section of the unit and passes through the condenser
coil and extracts heat.The hot air is blown out the
upper exhaust air opening. Evaporator air is taken
through the lower, front, louvered panel and is cooled
by the evaporator coil. It’s then blown in through four,
adjustable, four-way grilles, enabling a variety of
airflow possibilities. Both condenser and evaporative
air inlets are provided with filters.
ELECTRICAL
Electrical control is concentrated in an enclosed area
behind the control panel. Electrical interconnection is
achieved via a multi-position terminal strip located in a
junction box fastened to the bulkhead wall.

CEILING PANEL/DUCT KIT ASSEMBLY
(OPTIONAL)
A 10" diameter, flexible duct kit assembly extends up
to 10 feet, to vent condenser air or to draw condenser
return air from the ceiling when condenser return air
plenum is used. It comes with 2' x 2' lay-in ceiling
panel/collar assembly, for venting into the plenum area
above the false ceiling, plus a duct collar to attach duct
to unit. Installation of the flexible duct can be achieved
in the following manner:
1. Slip one end of the duct over the lay-in ceiling
panel/collar assembly and other end over the unit
duct collar.
2. Clamp duct to lay-in ceiling panel/collar assembly
and unit duct collar (see “Duct Design” for details.
3. Place the 2' x 2' lay-in ceiling panel in the false
ceiling directly above the unit.
4. Screw duct collar to unit with four screws provided.

DUCT DESIGN
Condenser Duct
Should a longer 10" diameter duct be needed on the
condenser discharge, 10 foot flexible ducts may be
coupled together up to a maximum equivalent length
of 60 feet (allow 6 feet for every 90°bend).

Duct Clamps
Two 10" diameter wire duct clamps are used to secure
the condenser air exhaust duct to the lay-in ceiling
panel/collar assembly and the Koldwave Airmaster
exhaust duct collar.
DISCHARGE AIR SNOZZLE®KIT ASSEMBLY
(OPTIONAL) SA040-D-028
A 20 gauge painted steel air discharge snozzle®
mounting plate assembly can be furnished as an
optional item. Its purpose is to accommodate various
spot cooling applications, where air can be aimed and
concentrated on the object to be cooled.The plate is
designed with two 4" diameter, 16" compressed and
22" long extended flexible air duct snozzles®.The use
of the snozzles®will derate the capacity by
approximately 13%.The snozzle®plate is mounted
over the evaporator air discharge opening by 1/4 turn
Pawl Latch fasteners for each removal. It is secured in
place by tightening the four fasteners provided with the
plate assembly. It can be removed easily by turning
the fastener on quarter turn counter-clockwise.
