mounted type thermostat(s), disconnect all power to the water heater.
To gain access to the surface mounted thermostat(s), remove the outer
access panel and fiberglass insulation. Using a screwdriver rotate the
thermostat dial on each thermostat clockwise to increase the water
temperature. After adjusting the surface mounted thermostats, replace the
fiberglass insulation making sure that the controls are well covered and that
the plastic terminal shield has not been displaced; replace the access panel.
Once the water heater has been filled with water, electrical power may be
restored to the water heater and the water heater is ready for operation. To

DANGER
Hotter water increases the risk of scald injury. Scalding may occur within five
(5) seconds at a temperature setting of 135°F (57°C). To protect against hot
water injury, install an ASSE approved mixing valve in the water system. This
valve will reduce point of discharge water temperatures by mixing cold and hot
water in branch water lines. A licensed plumbing professional or local
plumbing authority should be consulted.
Note: This water heater is equipped with an energy cut out device to prevent
overheating. Should overheating occur, turn off the electrical supply to the
water heater and contact a qualified service technician.
