Installation and Operation Instructions Manual
WARNING
Improper installation, adjustment, alteration,
service or maintenance can cause serious
injury or property damage. Refer to this
manual. For assistance or additional
information, consult a qualified installer or
service agency.
CAUTION
The recommended water temperature for
normal residential use is 120°F/49°F. Outlet
water temperatures may exceed the thermostat
setting. Measure water temperature at the tap
nearest to the water heater.
WARNING
Hotter water increases the risk of scald injury.
Before adjusting the water temperature
setting, read this instruction manual.
Temperatures at which injury occurs vary with
the person's age and the length of exposure.
The slower reaction time of children, elderly,
and physically or mentally challenged persons
increases the scalding hazard to them. It is
recommended that lower water temperatures
be used where these exposure hazards exist.
Such households may require a temperature
setting less than 120°F to prevent accidental
contact with hot water.
To lower water temperature use point-of-use
temperature limiting devices.
WARNING
Water heater blankets are not recommended
and will void the warranty.
CAUTION
This water heater is not intended for space
heating applications.

    SECTION II: GENERAL INFORMATION OVERVIEW This manual covers commercial electric water heaters intended for use as a swing tank in single-pass or multi-pass commercial heat pump water heating systems. All models are wired for connection to a three phase delta branch circuit and contain factory supplied internal fusing. Please reference the installation section of this manual for single phase applications.
  • Page 7 SECTION II: GENERAL INFORMATION ANODE RODS The anode rods are used as sacrificial elements within the volume of the storage tank. The purpose of the rods is to protect the inside of the tank against corrosion. Anode rods should be inspected twice in the first year and at least yearly once a time interval for inspection has been developed.
  • Page 8 SECTION II: GENERAL INFORMATION OUTDOOR SENSOR An outdoor sensor kit (Hydrolevel OS-100) is supplied with this water heater. Wire the sensor cable to the “Sensor 3” screw terminals located on the back of the operating control. Route the cable through the 7/8” knockout located at the top of the control panel enclosure (smallest knockout on right-side grouping).
