Bay Thermostat

A thermostat in the storage compartment turns
040486c
on the exchanger in the storage bay to prevent
freezing. The thermostat turns on at 45º F +/- 10º.
Ensure the Aqua-Hot is ON when heating the bay.
NOTE:
Turn the Aqua-Hot ON when heating
the bay.
Care & Maintenance
Heat Exchanger:
Exchangers can be affected by pet hair and
debris causing performance to suffer. The Aqua-
Hot exchangers require a minimum semi-annual
cleaning of the heating fi ns, blower fans and
register box. Clean the surrounding area outside
of the exchanger. A vacuum cleaner works well
040486a for this purpose.

Cleaning the register:
Gain access to registers located under sofas,
behind cabinets, or under false fl oors, depending
upon the fl oor plan. Access is limited. Be cautious
not to puncture coolant lines or register core.
Gently remove retaining screws. Set fans to the
side. Vacuum debris or hair from inside of register.
Use care not to bend or disfi gure fi ns on register
core. Vacuum fans then wipe clean with a soft
cloth or paper towel. Reinstall fans and registers.
Clean wood or metal vents in front of heat register
with a soft cloth or vacuum attachment.
Antifreeze:
The antifreeze, a special boiler type propylene
glycol base, has low silicate content with
corrosion inhibitors and heat transfer compounds.
This type of antifreeze provides freeze protection
and excellent heat transfer for operating
effi ciency. The antifreeze is mixed to a 50/50 ratio
with de-ionized water (water purifi ed by reverse
osmosis). DO NOT mix antifreeze types as this
can cause scaling and possible component failure.
The antifreeze can be purchased directly from
Vehicle Systems Inc.
CAUTION:
Use only a non-toxic propylene glycol
based antifreeze recommended for
boiler applications. This antifreeze
must be affirmed GRAS (Generally
Recognized as Safe by the EPA).
Contact Vehicle Systems Inc. at 1-800-
685-4298 to purchase the antifreeze.
