Service & Warranty
Servicing / Chassis Quick Change Outs
The chassis is designed for quick disconnect
and change out. For minor electrical service,
the Electrical Access Panel is easily removable
once the screws are removed. For major
electrical,refrigeration and fan service the chassis
may be removed from utility closet.
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 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, see above stated WARNING.
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 VRP
unit 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 chassis mounted return air filter:
1. Slide the holders away from the filter.
2. Remove the filter.
3. Install a new disposable filter.
4. The unit filter size is 14" x 20" x 1"
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 controller off.
B. Disconnect the power coming into the unit from
the main breaker panel or the closet mounted
disconnect.
C. Disconnect the electrical connection.
D. Disconnect the duct work.
E. Slide the chassis out of the wall plenum.
F. Slide and slightly 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 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 fins on the coil.
Bent fins should be straightened using a special fin tool
available from most HVAC supply depots.
Inspect Outdoor Air (OA) Intake and Exhaust
The unit's outdoor-air intake and outdoor-air exhaust paths
must remain clear. 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.
