450-D Hydronic Heating System Owner’s Manual
The Aqua-Hot’s Domestic Water Heating System must be
completely drained of domestic water any time the heater
is stored where freezing temperatures may be experi-
enced.
Winterizing the Domestic Water Heating System:
Please follow these instructions when winterizing the
Aqua-Hot’s Domestic Water Heating System; reference
Figure 10:
1. Completely drain the fresh water storage tank.
2. Disconnect the domestic water demand pump’s suc-
tion line from the fresh water storage tank.
3. Attach an adequate piece of hose onto the suction
side of the domestic water demand pump.
4.
Place the opposite end of the hose into an adequate
supply of FDA-approved “GRAS” RV Antifreeze.
5. Open and close all interior and exterior water fau-
cets, one at a time, until only pure RV Antifreeze is
present. Perform this procedure for both the hot and
cold faucets.
6. Remove the hose and reconnect the domestic water
demand pump’s suction line to the fresh water stor-
age tank.
De-Winterizing the Domestic Water Heating System:
For de-winterization, completely fill the fresh water stor-
age tank. Open and close all interior and exterior water
faucets, one at a time, until only clear water is present/
visible. Reference Figure 10.
If disinfecting the potable water system after de-
winterizing, be sure to follow RVIA’s “
Instructions for
Disinfection of Potable Water Systems on Recreation
Vehicles
.” These instructions can be obtained by con-
tacting the Recreational Vehicle Industry Association at

INTERIZATION
Figur
e 10
Not winterizing the Aqua-Hot when freezing tempera-
tures are present will result in serious damage to the
Aqua-Hot’s Domestic Water Heating System. Also,
be sure to use an FDA approved, “GRAS” rated anti-
freeze for winterization.
NOTE: The Aqua-Hot can continue to be used for interior
zone heating once the domestic water heating system
has been drained and winterized.
Remove the hose from the Fresh Water Storage Tank and attach an adequate piece of hose onto the suction
side of the demand pump. Place this hose into a container of RV Antifreeze and allow this to pump through
the Domestic Water System until the faucets run pure antifreeze.
