AHE-100-02S Hydronic Heating System Service Manual—Rev. B
APPENDIX F: WINTERIZATION PROCCESS
Not winterizing the Aqua-Hot when freezing temperatures
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 antifreeze 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.
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 experienced.
Winterizing the Domestic Water Heating System:
Please follow these instructions when winterizing the Aqua-
Hot’s Domestic Water Heating System; reference Figure F1:
1. Completely drain the fresh water storage tank.
2.
Disconnect the domestic water demand pump’s suction
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, and turn on the
demand water pump.
5.
Open and close all interior and exterior water faucets, one at
a time, until only pure RV Antifreeze is present. Perform
this procedure for both the hot and cold faucets.
6.
Turn off Demand Water pump and remove the hose and re-
connect the domestic water demand pump’s suction line to
the fresh water storage tank.
De-Winterizing the Domestic Water Heating System:
For de-winterization, completely fill the fresh water storage tank.
Turn on demand water pump and open and close all interior and
exterior water faucets, one at a time, until only clear water is
present/visible. Reference Figure F1.
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 contacting the Recreational Vehicle Industry
Association at
(703) 620-6003
