Installation and Operating Instructions
4.5 Water Chemistry Requirements
NOTICE
Product damage!
•
Chemical imbalance of the water supply may affect efficiency and cause
severe damage to the appliance and associated equipment. Water quality
must be professionally analyzed to determine whether it is necessary to
treat the water. Various solutions are available to adjust water quality.
Adverse water quality will affect the reliability of the system. In addition,
operating temperatures above 135°F (57 °C) will accelerate the build-up
of lime scale and possibly shorten appliance service life. Failure of an
appliance due to lime scale build-up, low pH, or other chemical imbalance
IS NOT covered by the warranty.
The water must be potable, free of corrosive chemicals, sand, dirt, and other
contaminants. It is up to the installer to ensure the water does not contain corrosive
chemicals or elements that can damage the water heater. Potable water is defined
as drinkable water supplied from utility or well water in compliance with EPA
secondary maximum contaminant levels (40 CFR Part 143.3). If the water contains
contaminants higher than outlined by the EPA, water treatment is required.
If you suspect that your water is contaminated in any way, discontinue use of the
appliance and contact an authorized technician or licensed professional.
Following water chemistry limits must be observed for the water supply:
pH
Hardness
Chlorine Concentration
Total Dissolved Solids
Conductivity μS/cm

WARNING
Personal injury, property damage!
•
This water heater must be installed in accordance with all national, state
and local codes and ordinances. If additional information are desired, the
latest edition of the National Electric Code "NFPA 70" are recommended.
This code can be obtained from the National Fire Protection Association at
Battery March Park, Quincy, MA 02269. For Canadian installations, refer
to the Canadian Electric Code (CSA22.1). A copy can be purchased from
the Canadian Standards Association at 5050 Spectrum Way, Mississauga,
ONT L4W 5N6.
Before proceeding with the installation, close the main water supply
valve, open a water faucet to relieve the water pressure, and then close
the faucet.
This water heater is not intended for space heating applications.
