WHL-004 REV. 5.26.17
NOTICE
If the water heater is exposed to the following, do not operate until all corrective steps have been made by a qualified service
technician:
1. FIRE
2. DAMAGE
3. WATER
DO NOT alter or modify the water heater or water heater controls. This can be dangerous and WILL VOID the warranty.
This water heater is equipped with a three prong plug. It should only be plugged directly into a properly grounded three prong
receptacle. DO NOT remove the ground plug from the plug.
Any claims for damage or shortage in shipment must be filed immediately against the transportation company by the consignee.
This water heater provides a overheat shutdown limit. In the event the water heater water exceeds the set point of the control limit, the
cutoff will trip and the water heater will shut down. Certain local codes require additional temperature limits. In addition, certain types of
systems may operate at temperatures below the minimum set point of the limit provided with the water heater. Contact Westinghouse
for additional overheat controls.
NOTE: When inquiring about service or troubleshooting, reference the model and serial numbers from the water heater rating label.
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN SUBMERGED IN WATER. Immediately call a qualified service technician.
The appliance MUST BE replaced if it has been submerged. Attempting to operate an appliance that has been submerged could create
numerous harmful conditions, such as a potential gas leakage causing a fire and/or explosion, or the release of mold, bacteria, or other
harmful particulates into the air. Operating a previously submerged appliance could result in property damage, severe personal injury,
or death.
NOTE: Appliance damage due to flood or submersion is considered an Act of God, and IS NOT covered under product warranty.
Be sure to disconnect electrical power before opening water heater cabinet or performing service. Label all wires while performing
service to ensure proper re-wiring of the water heater. Wiring errors can cause improper or dangerous operation. Failure to do so could
result in an electrical shock, improper water heater operation, property damage, serious personal injury, or death.
B. IMPROPER COMBUSTION
Do not obstruct the flow of combustion and ventilating air. Adequate air must be provided for safe operation. Failure to keep the
exhaust vent and intake pipe clear of ice, snow, or other debris could result in property damage, serious personal injury, or death.
C. GAS
Should overheating or gas supply fail to shut off, do not turn off or disconnect electrical supply to the circulator. Instead, shut off the gas
supply at a location external to the appliance.
D. WHEN SERVICING THE WATER HEATER
 To avoid electric shock, disconnect electrical supply before performing maintenance.
 To avoid severe burns, allow water heater to cool.
 Do not use petroleum-based cleaning or sealing compounds in a water heater system. Gaskets and seals in the system may
be damaged, possibly resulting in substantial property damage.
 Do not use “homemade cures” or “patent medicines”. Substantial property damage, damage to water heater, and/or serious
personal injury may result.
 Always verify proper operation after servicing the water heater.
E. WATER CHEMISTRY
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
o
F 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 heat exchanger. 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) as shown in the
table below. If the water contains contaminants higher than outlined by the EPA, water treatment is recommended and additional, more
frequent maintenance may be required.
