Service & Warranty
Servicing / Chassis Quick Changeouts
The chasis 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.
WARNING
Electrical Shock Hazard
Pull out electrical disconnect on front of
the chassis and turn off all power to unit
before servicing.
Failure to do so can result in property
damage, personal injury and/or death.

Routine Maintenance

Performing Routine Maintenance
With the proper maintenance and care, your system will
operate ecomomically and dependably. Maintenance can be
accomplished easily by referring to the following directions.
However, before performing any maintenance, see above
stated WARNING.
CAUTION
Cut/Sever Hazard
Some edges may be sharp, use gloves
or other hand protection when handling
unit.
Failure to do so can result in minor to
moderate personal injury.
Replace Air Filter
A dirty air filter reduces the efficiency 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.
The air filter should be replaced as it becomes dirty.
To replace the filter (chassis mounted return air filter):
1. Slide the filter clear of the filter rails.
2. Remove the filter.
3. Install new disposable filter.
NOTE:
DO NOT OPERATE YOUR SYSTEM WITHOUT A
FILTER IN PLACE OR BLOCK THE FRONT OF THE UNIT
RETURN AIR OPENING.
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 power coming into the unit from the main
breaker panel or the closet mounted disconnect.
D. Disconnect the electrical connection.
E. Disconnect the duct work.
F. Slide the chassis out of the wall plenum.
G. Lift the chassis out of the utility closet.
Inspect and Clean Indoor-air Coil
Eventually, minor amounts of lint and dirt may pass through
the filter and collect on the indoor-air. These minor
accumulations can be carefully vacuumed away with a
brush attachment on a vacuum claner. Care must be taken
to avoid bending the aluminum finns on the coil. Bent fins
should be straightened using a special fin tool avalable from
most HVAC supply depots.
In spect Outdoor-Ai r (OA) 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 efficiency of your unit and
could damage it.
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 flow 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 warranty service work must be done by an authorized
servicer. See Product Warranty, and consult your dealer or
contractor for details.
