Sanitizing the Fresh Water System
Use the following procedures to sanitize your Fresh Water
System (or Potable Water System) when it is new, becomes
contaminated, or has not been used for a period of time.
Before you begin:
• For the Tankless Water Heater: KEEP BOTH water
heater bypass valve handles in the Normal position.
• For the 6-Gallon Water Heater: TURN BOTH water
heater bypass valve handles to the Bypass position.
• If you have installed an aftermarket water filter,
make sure that it is set to the Bypass position.
To sanitize the fresh water tank & fresh water system:
• PREPARE a Chlorine Solution using one (1) gallon of
water and one-quarter (1/4) cup of household bleach
(5% Sodium Hypochlorite solution).
• PREPARE approximately one (1) gallon of solution for
every fifteen (15) gallons of holding tank capacity.
NOTE: As an option, several commercial solutions are
available, and should be used as directed on the package.
1. POUR the * Chlorine Solution into
the gravity water fill inlet.
2. TURN ON the water pump.
3. OPEN all faucet fixtures, allowing all
of the solution to pass through.
4. ALLOW the solution to stand for three (3) hours, then
◦ DRAIN tank and FLUSH the system with fresh water.
◦ BEFORE use, RUN plenty of water through
the entire system.
To remove excessive chlorine odor or taste
which may remain:
5. PREPARE a Vinegar Solution of one (1) quart vinegar
to five (5) gallons water.
◦ PREPARE approximately one (1) gallon of solution for
every fifteen (15) gallons of holding tank capacity.
6. Pour the * Vinegar Solution into the fresh water
gravity fill inlet
7. REPEAT steps 2-4 above.
