VERT-I-PAK SINGLE PACKAGED VERTICAL AIR CONDITIONERS
9,000 / 12,000 / 18,000 / 24 K BTUs/h
All units are factory assembled, piped, wired and fully charged with R-22. Units are ETL listed and carry an ETL
label. Units are approved for 0” clearance. All units are factory run-tested to check operation.
REFRIGERATION SYSTEM –
The current Vert-I-Pak 9, 12, & 18 use a dual shaft, permanent split capacitor,
The refrigeration system consists of a hermetically sealed rotary compressor that is
externally mounted on vibration isolators; condenser and evaporator coils constructed of copper tubes and aluminum
plate fins; and capillaries as expansion devices. The coils are of draw-through design to facilitate cleaning. Unit has
a fan slinger ring to increase efficiency and condensate disposal and have a primary condensate removal system
consisting of ¾” FPT drain connections built into the unit for easy removal. A secondary condensate removal system is
also available for back up and shall overflow through the wall plenum and to the outside of the building.
INDOOR BLOWER / OUTDOOR FAN –
CONTROLS – Are electronic and factory equipped with terminal strip for connection to a standard 24-volt single-stage
heat/cool thermostat. A 24 volt transformer is included. The unit is to be hard-wired. It has a quick-disconnect to
disable power for control box service.
GENERAL CONSTRUCTION – The unit is constructed of 18 gauge G90 zinc-coated steel. It is insulated for
thermal efficiency. The wall plenum (required factory accessory) is constructed of 20 gauge G90 zinc-coated steel;
pre-treated with zinc-phosphate and sealed with a chromate rinse, then powder coated for maximum coverage and
protection. The architectural louver (required factory accessory) is fabricated from extruded anodized aluminum
with louvers in the horizontal plane.
The unit includes two vibration isolators mounted under the chassis and a non-rigid plenum-to-chassis connection to
isolate vibrations to the building.
The unit has a plastic fan, fan shroud and drain pan for corrosion protection and to help prevent rust on the side of
the building below the outdoor louver.
The unit is shipped with return air filter brackets and a 14" x 20" filter affixed directly on to the unit chassis. Other
optional factory accessories are available for mounting the return air filter in the mechanical closet door or an access
panel.
Optional return air grilles shall be available as factory accessories for installation in the wall or door of the mechanical
closet.
The 9,12 and 18 K BTUs units are 23 1/8” wide x 23 1/8” deep x 32 1/4” high. The 24 K BTUs unit is 23 1/8“ wide by 23
1/8” deep x 47 1/4“ high. Units draw in ambient air through upper portion of an outside architectural louver measuring
25 9/16” wide x 31 1/16” high and shall exhaust heated air out through the lower portion of the louver. The unit is to be
inserted to the architectural louver by means of a two part, weather-resistant wall plenum. The unit is capable of left,
right or straight-in installations into mechanical closet without field modifications.
dual speed motor to drive indoor blower and outdoor fan. The Vert-I-Pak 24 uses an individual, single shaft, permanent
split capacitor, dual speed motor for the indoor blower and a separate single speed motor drives the outdoor fan.
Different size (HP) motors and/or different diameter blower wheels are used in different models to obtain the required
airflow.
