Service And Warranty - Friedrich VERT-I-PAK VHA09K Installation & Operation Manual

Service & Warranty
Servicing / Chassis Quick Change Outs
The chassis is designed for quick disconnect and change
out. For minor electrical service, the control box cover lifts
straight up after the screws and disconnect pull-out are
removed. For major electrical,refrigeration, and fan service
the chassis should be removed from the 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
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 Vert-I-Pak unit
and allows lint and dirt to accumulate on the indoor coil.
Lint and dirt on the indoor 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 sizes are
20" x 14" x 1" or 20" x 18" x 1" (VHA24)
NOTE: DO NOT OPERATE YOUR SYSTEM
WITHOUT A FILTER IN PLACE OR BLOCK THE FRONT OF
THE UNIT RETURN AIR OPENING.
Performing Routine
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.
To Remove the Chassis from the Closet:
1. Switch the unit off at the thermostat.
2. Disconnect the power coming into the unit from
the main breaker panel or the closet mounted
disconnect.
3. Disconnect the electrical connection.
4. Disconnect the duct work.
5. Slide the chassis out of the wall plenum.
6. Slide and slightly lift the chassis out of the utility
closet.
