Care and Cleaning
Turn off the Zoneline and disconnect the power supply before cleaning.
Air Filters
NOTICE: Do not operate the Zoneline without the
filter in place. If a filter becomes torn or damaged, it
should be replaced immediately.
Operating without the filter in place or with a damaged
filter will allow dirt and dust to reach the indoor coil and
reduce the cooling/heating, performance, airflow, and
efficiency of the unit.
The most important thing you can do to maintain the
Zoneline is to change the filter at least every 30 days.
Dirty filters reduce cooling, heating performance and air
flow.
Changing the filter will: Decrease cost of operation,
save energy, prevent clogged heat exchanger coils, and
reduce the risk of premature component failure.
Replacement filters should be purchased from your local
retailer where air conditioner and furnace accessories
are sold. If MERV13 filtration is desired, use RAVRG4*
Drain
Clean the drain system regularly to prevent clogging.
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 impeded the flow of
Indoor/Outdoor Coils
The Indoor/Outdoor coils on the Zoneline should be
cleaned and checked regularly.
NOTE: When cleaning the coils do not use
acid-based coil cleaners, or cleaning agents with
formic or acetic acids. Care must be taken to avoid
bending the aluminum fins on the coils. Do not use
any high pressure spray mechanisms.
Indoor-Air Coil
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 or
professionally cleaned.
Outdoor-Air Coil
The unit's outdoor-air intake and outdoor-air exhaust
paths must remain clear. Check the outdoor-air exhaust
frequently. Keep it free of all debris, snow, or ice. The
Base Pan
In some installations, dirt or other debris may be blown
into the unit from the outside and settle in the base pan
(the bottom of the unit).
49-5000640 Rev. 1
with 2" filter.
Filter size for front of unit is 18" x 20" x 1".
Filter sizes for RAVRG4* is 24" x 20" x (1" or 2") .
Filter sizes for RAVRG2* is 20" x 20".
NOTE: Use only one filter in the installation.
To replace the filter (unit mounted return air filter):
1. Slide the filter up to clear the filter holders.
2. Remove the filter.
3. Install new disposable filter.
To maintain optimum performance, change the filter
at least every 30 days. For other filter installation
options, see page 7.
condensate water. If there is any accumulation of foreign
matter in the drainpipe, it should be removed and cleaned.
The entire drain line must be protected from freezing.
outdoor-air intake
should also be kept
free of obstructions.
Blocking the outdoor-air
exhaust or outdoor-air
intake opening will
reduce the efficiency
of your unit and could
cause premature
compressor failure.
Inspection and cleaning
of the outdoor-air
coils may require the
unit to be removed
from the closet. See servicing section of this manual
for instructions on how to remove the unit. Professional
cleaning is recommended for the inside surface of the
outdoor coil. Use care to cover and protect electrical
controls and components during the cleaning process.
In some areas of the United States, a "gel-like" substance
may be present in the base pan.
Check it periodically and clean, if necessary.
Have the coils cleaned regularly.
