IMPORTANT
!
Any of the following quick start instructions provided by Newmar should not take the place of the manufacturer’s
complete documentation. Refer to Newgle for more information about heating, ventilation, and air conditioning
components offered for your coach’s model year.
Roof Air Conditioning and Heat Overview
This article provides a brief overview of the roof air conditioning and heat pump, as well as filter maintenance. Keep your
coach comfortable year around!
On some coach models, grills with filters may be located
behind decorative covers on the ceiling.
1. Remove the vent cover grill from the return air duct
or the grill from the air conditioner ceiling assembly.
2. Remove the filter.
3. Wash, rinse, and dry the filter. If the filter does not
come clean, or is damaged, replace it with a new
filter. Do not substitute other types of filters, as this
may restrict air flow and cause other issues. Do not
operate the air conditioners without filters.
4. Reinstall the filter on the cover, and place it back into
the vent.
5. Repeat the process for each return air vent.
For more information about accessing filters underneath
decorative covers, refer to other Newgle articles (How to
Access and Clean Air Conditioner Filters with... louvered
wood covers, friction, mechanical, or magnetic latch
covers).
Filter Maintenance
Air Conditioning and Heat, Roof
Your coach’s air conditioners can be operated using the
Comfort Control thermostat, KIB V-Bus LCD touchscreen,
or the appropriate SilverLeaf screen. For more detailed
information about climate control, refer to the appropriate
product page(s) and associated content in Newgle.
Some roof top air conditioners have the ability to work
as a heat pump when desired to produce heat instead of
cooling. These models are effective at producing heat at
ambient temperatures (above approximately 40 degrees).
If the temperature drops below the threshold, most
controls will revert to the furnace or hydronic heating
system to produce the necessary heat.
Most air conditioning systems have a two minute built-in
time delay, so there may be a slight delay in the operation
of the air conditioner after the thermostat is set.
