Thermostat adjustment
The thermostat is located in the front of the heater. The
access cover must be removed to adjust to the factory
default setting of 119°F. This temperature is satisfactory
for the average household use. If an adjustment is
necessary, turn off the power to the heater, remove
the black access cover and insulation. The thermostat
protective cover should not be removed. Set the
temperature indicator to the desired temperature, replace
insulation and access cover. Turn on power to heater.
Combination – Thermostat and
high limit control (ECO)
This heater is equipped with a combination thermostat and
high limit safety. If for any reason the water temperature
becomes excessively high, the “high limit control (ECO)”
breaks the circuit to the heating element. Once the switch
opens, it must be reset manually. However, THE CAUSE
OF THE OVER TEMPERATURE CONDITION MUST BE
CORRECTED FIRST. REFER TO THE TROUBLE SHOOTING
SECTION for possible causes. To reset, press the red reset
button as shown. Replace the insulation and black access
cover before turning on power to the heater.
Charging the potable water
system
Solar storage tank
Fill the solar tank with water. Do this by opening the cold
water isolation ball valve to the solar tank. Inspect all
fi ttings for leaks. Purge all air from the potable water
system by turning on several hot and cold faucets and
running water for several minutes. Air is purged when
water runs continuously for 1-2 minutes without air
discharge.
After the water and electrical connections have been
made, the tank has been fi lled with water, and all air has
been purged from the tank, turn on power to heater. The
heater is now operational.
