Drain Pan Installation
Condensate Disposal System
The VPDP1 drain pan features two ¾ female PVC ttings to at-
tach a drain connection to on the left or right side of the drain pan.
Condensate piping can be routed to the left, right or beneath the
unit platform. See drain pan installation manual for more information.
Part 1: The system’s rst stage increases energy efciency
utilizing a factory installed fan that slings the cold
condensate onto the hot outdoor coil.
Part 2: When high outdoor humidity prevents the slinger
from disposing of all the condensate, the excess
condensate overows into the condensate drain pan
and out of the ¾" internal drain connections.
Part 3: If Parts 1 & 2 fail for any reason, excess condensate
overows from a spillway directly into the wall plenum
to the outside of the building. IF THIS OCCURS,
THIS IS A WARNING THAT THE CHASSIS OR
DRAIN NEEDS SERVICING.

Ductwork Preparation
Duct ESP:
To determine your system's indoor external static pressure (ESP,
in inches of water) use a duct calculator (as provided by your duct
supplier). Include all ex duct transitions and discharge grille(s).
If ex duct is used, be sure all the slack is pulled out of the ex
duct. Flex duct ESP can increase considerably when not fully
extended. DO NOT EXCEED a total of .30 ESP, as this is the
MAXIMUM design limit for the VERT-I-PAK A-Series unit.
Chassis Installation
Install the following components
A. Ensure that the wall plenum is installed in accordance
with the VPAWP1-8/1-14 Installation Manual.
B. Place the chassis into the closet with the outdoor side
facing the wall plenum opening.
C. Slide the chassis into the wall plenum until the plenum
divider seal is established. (See Figure 9)
The Vert-I-Pak chassis must be inserted into the wall plenum so that the plenum divider gasket makes contact with the plastic condenser
bafe on the unit. The chassis will t approximately 23/8" into the wall plenum.

Final Installation Checklist
Correct line voltage?
Chassis deck level?
Plenum divider bafe installed?
Wall plenum caulked? Level? Flashing?
HACR type breaker/fuse?
Single circuit only?
Ductwork connected?
Chassis weather seal in place?
Wall thermostat wired correctly?
Chassis inserted into plenum?
Chassis Final Connections
With the chassis in place, you are now ready to begin chassis
connections:
A. Move the thermostat switches to "OFF" and "AUTO." This
will keep the thermostat from cycling the chassis until nal
connections are complete.
B. Connect the ductwork onto the 10" collar. Plastic wireties
(eld supplied) are suggested to secure the ductwork in
place. Use 2 wire ties, one for each inner and outer ex
duct sleeve.
C. Review the Final Installation Checklist on Page 12 before
replacing the power quick disconnect, reconnecting power
to the chassis, plugging in the remote thermostat harness,
or operating the chassis.
Electrical shock and moving parts hazard can cause injury or death. If you have not done so, pull out the disconnect head
found on the front of chassis before continuing installation! Disconnect external power at the breaker.
Chassis Operation
Fresh Air Door
The Fresh Air Door is an "intake" system. The fresh air door is
opened via a slide on the front of the chassis located just above
the indoor coil. Move the slide left to open and right to close the
fresh air door. The system is capable of up to 60 CFM of fresh
air @ ~.3" H20 internal static pressure.
Low Ambient Protection
Each chassis is equipped with low ambient protection in the form
of a thermistor, which will prevent compressor operation at low
suction temperature.
Room Freeze Protection
Units are shipped from the factory with the room freeze protection
disabled. Room Freeze Protection can be switched on at the
owner’s preference by moving Dip Switch 6 to ‘ON’. This feature
will monitor the indoor room conditions and in the event that the
room falls below 40°F the unit will cycle on high fan with the
electric heater. This occurs regardless of mode.
Emergency Heat Override
In the unlikely event of a compressor failure a heat pump unit
may be switched to operate in only the electric heat mode until
repairs can be made. Moving Dip Switch 7 to ‘ON’.
Emergency Heat Operation
In the event of a compressor failure in heat pump mode the com-
pressor may be locked out to provide heat through the resistance
heater. This feature ensures that even in the unlikely event of a
compressor failure the room temperature can be maintained
until the compressor can be serviced. Dip switch 7 controls the
emergency heat setting (see above).

For minor electrical service, the control box cover lifts straight
up after the screws & disconnect head are removed. For major
electrical, refrigeration and fan service the chassis may be
removed from utility closet.
To Remove the Chassis from the Closet:
A. Switch the wall Thermostat off.
B. Pull the Power Disconnect located in the front of the chassis.
C. Disconnect the thermostat wiring harness.
D. Disconnect the electrical connection.
E. Disconnect the ductwork.
F. Slide the chassis out of the wall plenum.
G. Lift the chassis out of the utility closet.
Routine Maintenance
Performing Routine Maintenance
With the proper maintenance and care, your system will
operate economically and dependably. Maintenance can be
accomplished easily by referring to the following directions.
However, before performing any maintenance, consider these
important safety precautions:
WARNING: Electrical Shock Hazard. Before attempting any
service work or routine maintenance, turn off all electrical
connections to the unit. Failure to do so may result in property
damage, personal injury and/or death.
CAUTION: Although great care has been taken to minimize sharp
edges in the construction of your unit, be extremely careful when
handling parts or reaching into the unit.
Replace Air Filter
A dirty air lter reduces the efciency of your Vert-I-Pak and
allows lint and dirt to accumulate on the indoor-air coil. Lint and
dirt on the indoor-air coil can damage your unit and void the
warranty. The air lter should be replaced as it becomes dirty.
To replace the lter (chassis mounted return air lter):
1. Slide the lter clear of the lter rails.
2. Remove the lter.
3. Install new disposable lter.
CAUTION: Do not operate your system without a lter in place,
nor block the front of the unit return air opening.
Inspect and Clean Indoor-air Coil
Eventually, minor amounts of lint and dirt may pass through
the lter and collect on the indoor-air coil. These minor
accumulations can be carefully vacuumed away with a brush
attachment on a vacuum cleaner. Care must be taken to avoid
bending the aluminum ns on the coil. Bent ns should be
straightened using a special n tool available from most HVAC
service technicians.
Inspect Outdoor-air Intake and Exhaust
The unit’s outdoor-air intake and outdoor-air exhaust paths must
remain clear. Check the OA exhaust frequently. Keep it free of
all debris, snow, or ice. The OA intake should also be kept free
of obstructions. Blocking the OA exhaust or OA intake opening
will reduce the efciency of your unit, could damage it, and may
void your warranty.
Inspect and Clean Condensate Drain
The condensate drain must be routed to a suitable drainage
area. Check the unit condensate drain periodically. Keep it free
of anything that may block or impede the ow of condensate
water. If there is any accumulation of foreign matter in the drain
pipe, it should be removed and cleaned. The entire drain line
must be protected from freezing.
Warranty
All service work must be done by a qualied servicer. See Product
Warranty, and consult your dealer or contractor for details
