NOTE:
Turn the thermostat to the
Off position when cleaning
the exchangers.
Cleaning the Exchanger:
Exchangers can be located
under the sofa, behind cabinets or
under false oors in base cabinets.
Access may be limited. Use
caution to not puncture coolant
lines or exchanger core. Gently
remove retaining screws. Set fans
to the side.
Vacuum debris and hair from
inside of register. Use care not
to bend or disgure ns on
exchanger. 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.
Coolant:
The coolant is a special
“boiler type” propylene
glycol base coolant. It has
low silicate content with
corrosion inhibitors and
heat transfer compounds.
This type of antifreeze
provides freeze protection
and excellent heat transfer
for operating efciency.
The coolant is mixed
50/50 with de-ionized
water (water puried by reverse
osmosis). Do not mix with
automotive antifreeze as this
can cause scaling and possible
component failure. The coolant
can be purchased directly from
Vehicle Systems Inc.
CAUTION:
Use only non-toxic
propylene glycol based
coolant recommended for
boiler applications. The
coolant is FDA approved
GRAS (Generally
Recognized as Safe by
the FDA). To obtain the
recommended antifreeze,
contact Vehicle Systems
Inc. at 1-800-685-4298.
Reservoir:
The coolant reservoir is located
in the bay with the Aqua-Hot.
Check the reservoir level monthly.
The proper coolant level should
be at the Full Hot level when the
diesel burner has just shut off.
If necessary, add coolant to
the reservoir only when the
Aqua-Hot has achieved operating
temperature to prevent overow
when the system cools.
Disinfecting:
The tubing inside the Aqua-
Hot is rated for fresh water and
winterizing solutions. The Aqua-
Hot domestic water loop can be
disinfected periodically by ushing
a disinfecting solution through
the Aqua-Hot. The disinfecting
solution must be thoroughly rinsed
otherwise damage to the Aqua-Hot
domestic water loop can occur.
CAUTION:
If not properly and
thoroughly rinsed, bleach
or other concentrated
chlorine bearing chemicals
can cause failure of the
domestic water loop inside
the Aqua-Hot.
CAUTION:
Disconnect all sources of
power before cleaning or
servicing.
Winterize the Aqua-Hot
The Aqua-Hot can remain on
during the winter months. If the
motorhome is to be winterized and
stored over the winter with the
Aqua-Hot turned off, the Aqua-
Hot domestic water loop must be
winterized with FDA approved
RV antifreeze to prevent freeze
damage.
NOTICE
Use only a non-toxic Propylene Glycol
based boiler antifreeze that meets FDA
(GRAS) standards. For more information,
contact Aqua-Hot Heating Systems Inc.
