Adjustments
Adjusting the Temperature Setting:
The temperature setting slide is on the right-hand side of the TPI. (See Diagram 3)
The TPI comes with a factory set temperature setting of 120
F.
To adjust the temperature setting, slide the lever to the desired setting, using the indicator scale.
TPI has a normal temperature setting range from 100
F to 140
F.
CAUTION: IT IS NOT RECOMMENDED TO SET TEMPERATURE ABOVE 140
F.
(SEE WATER TEMPERATURE REGULATION below)
In order to set the temperature above 140
F, {
NOT RECOMMENDED
},you must remove the SCALD
DANGER label attached to the temperature slide.
Adjusting the Differential Setting:
The differential setting slide is on the left-hand side of the TPI. (See Diagram 3)
The TPI comes with a factory set differential setting of 10
.
This means that the TPI will call for heat when the tank temperature has fallen to 10 degrees below the
Temperature set point.
To adjust the differential setting, slide the lever to the desired setting, using the indicator scale.
WATER TEMPERATURE REGULATION
WARNING: Exposure to 125° F or hotter water can cause scalding injuries. Appropriate caution must
be taken when using hot water. Special supervision must be given to those who cannot act quickly
such as children, invalids or elderly persons.
The input of heat into the tank is controlled by an immersion thermostat. These automatic controls are set at
the factory to maintain a water temperature of 120° F*.
*Although these thermostats are designed to industry standards, they can fail to control temperature properly
without any notice, and therefore should be tested periodically for your protection.
DANGER: IF YOU DISCOVER EXTREME HOT WATER COMING FROM THE FAUCET, IMMEDIATELY
SHUT OFF THE MAIN SWITCH TO THE BOILER AND CALL COMPETENT SERVICE PERSONNEL. ANY
OVERHEATED WATER IS A POTENTIAL HAZARD TO LIFE AND PROPERTY. DO NOT OPERATE UNTIL
THE SOURCE OF THE PROBLEM HAS BEEN DETERMINED AND ELIMINATED.
Water temperature over 125° F can cause severe burns instantly or death
from scalds.
Children, disabled and elderly are at the highest risk of being scalded.
See instruction manual before setting temperature at the water heater.
Feel water before bathing or showering.
