De-Winterizing the Water Heater and Fresh Water System
1. Close all faucets, water outlets, the water heater drain and pressure relief valve.
2. If during the winterizing procedure the anode was removed and replaced with a 3/4" male pipe
thread drain plug, remove the drain plug and replace with anode.
3. Fill fresh water tanks with fresh water approximately so that 115% to 120% of the water heater
capacity remains in the fresh water tanks.
Example: If water heater is 11 gallons = 12 to 13 gallons in fresh water tanks.
CAUTION
SPECIAL PRECAUTIONS MUST BE USED WHEN DRAINING AND FILLING
AN ELECTRIC WATER HEATER. ELECTRICITY MUST BE TURNED OFF
BEFORE DRAINING AND REFILLING WATER HEATER TANKS.
4. Turn on fresh water pump.
5. Open each faucet and water outlet one at a time until winterizing chemical is no longer apparent
at the opening. This allows the fresh water to ush the winterizing chemicals out of the fresh
water system.
6. Fill fresh water tanks to 100% capacity.
NOTICE
Whale Heat recommends that while lling the fresh water storage tanks that a
small amount of common household bleach be added to the fresh water system to
control the possible growth of algae. If an algae condition starts it is very difcult
to control.
Example: 1 oz. of bleach for every 50 gallons of fresh water.
7. Fresh water system is now de-winterized and ready for use.
