To the Consumer:
Please read these and all component
instructions and keep for future reference.

INSTALLER RESPONSIBILITIES
Please read all instructions thoroughly before
installing or placing the heater into service.
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 temperature for normal
residential use is 120°F. The dial on the
aquastat does not always reflect the outcoming water temperature, which could
occasionally exceed 120°F. The variation in
out-coming temperature could be based on
factors including but not limited to usage
patterns and type of installation. Test your
water 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.

SECTION II: GENERAL INFORMATION
SOLAR STORAGE TANK WITH ELECTRIC BACKUP FUNCTION
The solar storage tank is designed to store water that has been directly heated in a solar panel
or indirectly heated by a solar panel through an external heat exchanger.
During periods of water flow through the storage tank, hot water is drawn from the top of
the tank and cold water is delivered to the bottom of the tank (by a diptube or bottom inlet).
If the hot water demand should exceed the solar heat output, the heating element thermostat
will activate the electrical heating element for backup heat.
WATER TREATMENT/FILTRATION
In areas where poor water conditions are suspected (i.e. lime, iron, and other minerals), it is
essential that the water be tested and appropriate action taken to prevent damage to the
indirect heater and ensure the quality of the water.
Standby Loss
Rating (°F/hr)
TEMPERATURE CONTROL
A solar controller (not provided) shall be used in conjunction with the solar storage tank to
run all solar components in the heating system. The solar controller will be connected to two
thermistors that monitor lower and upper tank temperature. In some cases, only one
thermistor (near the bottom of the tank) will be used. The proper temperature setting for
domestic hot water use is 120°F/49°C.
The solar storage tank is equipped with a backup electrical heating element and adjustable
thermostat. The thermostat is located behind the access cover on the side of the water heater.
If the solar system cannot satisfy the user demand, the electric element will energize and heat
the water until the thermostat is satisfied. An ECO (electrical cut-off) is included as part of
the temperature control and is designed to cut off power to the heating element in the event
the water in the tank reaches 180°F. The ECO is a safety feature on the water heater and
cannot be adjusted. In the event that the ECO opens, the control must be manually reset with
the stored water temperature below 180°F.

SECTION II: GENERAL INFORMATION (cont.)
The thermostat is factory set at 120°F. See Table 6 for thermostat letter and temperature
relationships. If hotter water is required a tempering device or anti-scald device must be
installed at the domestic hot water outlet of the heater or at the point of use. Table 3 details
the approximate relationship of water temperature and time with regard to scald injury. It is
important for the user to understand the necessity of tempering or anti-scald devices when
using hotter water in domestic water heating systems.
CAUTION: Hot water in excess of 120°F can cause scalding!
Bock recommends a tempering valve or anti-scald valve be installed and used according to
the manufacturer’s directions to prevent scalding. Many state and local codes now require
installation of these devices. The tempering valve or anti-scald valve will ensure potable
water temperatures at the desired set point with a higher degree of accuracy.
