How to calibrate your hot water using water valve
DANGER: Hotter water increases the potential for hot water SCALD
1. Make sure all electrical wires and water pipes are properly installed. Check
the power requirement for each model. Before start up, check that all
connections are secure and fittings are tight. Confirm that all air has been
purged from the system.
2. Turn power on and verify the unit set temp is 105-110 degrees. Open tub
faucet. The water begins to heat and the current temperature is shown in the
display. Dial the Gate Valve on the Hot Side Only to calibrate your hot water
vs the flow rate. Ideally, you will gain a higher flow rate by lowering the set
temp as water moves through the water heaters quartz elements faster. If
hotter water is required, simply raise the set temp and/or slow the water flow
rate to meet your temperature needs.
3. Calibrate using Gate Valve (water valve) at hot outlet and choose a
desirable temperature by pressing the up or down buttons and adjusting the
gate valve until you have a comfortable water temperature and flow rate.
Never use the cold inlet valve to adjust flow. This will restrict water from
flowing in and cause damage to the heating elements.
4. Turn off water and unit is set.
