Storage
4.1 Domestic Hot Water System
The Aqua-Hot's domestic hot water system must be completely drained of
domestic water any time the heater is stored where freezing temperatures
may be experienced.
CAUTION: Not winterizing your Aqua-Hot, when freezing temperatures
are present, will result in serious damage to the Aqua-Hot's domestic
hot water system.
NOTE: The Aqua-Hot can still be used for interior zone heating even if the
domestic hot water system has been drained and winterized.
Follow the instructions listed below when winterizing the Aqua-Hot’s
domestic water system:
A. Completely drain the fresh water storage tank.
NOTE: If your coach is equipped with appliances that use fresh water (i.e.
ice makers, water purifiers, etc.) follow the manufacturer's
recommendation for winterization.
B. Disconnect the domestic water demand pump's suction line from the
fresh water storage tank.
C. Attach an adequate piece of hose onto the suction side of the domestic
water demand pump.
D. Place the opposite end of the hose into an adequate supply of FDA
approved RV-Antifreeze; approximately 2 gallons will be required.

E. Open/close all interior and exterior water faucets, one at a time, until only
pure RV-Antifreeze is present. Perform this procedure for both hot and cold
faucets.
F. Remove the hose and reconnect the domestic water demand pump's
suction line to the fresh water storage tank.
G. Disconnect all electrical power supplies to the Aqua-Hot during storage.
NOTE: 1. For de-winterization, fill the fresh water storage tank with fresh
water. Open/close all interior and exterior water faucets, one at a time, until
only clear water is present/visible.
