12) 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.
13) Condensate Disposal System
The VPDP1 drain pan features two female PVC ttings to
attach 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 page 8 or the drain pan installation manual for more
information.
Part 1: The system’s rst stage increases energy
efciency 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 overows into the condensate drain
pan and out of the " internal drain connections.
Part 3: If Parts 1 & 2 fail for any reason, excess
condensate overows from a spillway directly into
the wall plenum to the outside of the building. IF
THIS OCCURS, THIS IS YOUR WARNING THAT
THE CHASSIS OR DRAIN NEEDS SERVICING.
IV. Service & Warranty
14) Servicing / Chassis Quick Changeouts
The chassis is designed for quick disconnect and change out. 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.
Electrical shock and moving parts hazard can cause injury
or death. Pull out the disconnect head found on the front
of the chassis before servicing.
15) 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 efciency 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 efciency 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.
16) Warranty
All service work must be done by a qualied servicer. See Warranty
on the next page, and consult your dealer or contractor for details
