PRECAUTIONS
CAUTION
To prevent electrical shock and/or equipment dam- age, disconnect electric power to system, at main fuse or circuit breaker box, until installation is complete.
WARNING
Do not use on circuits exceeding specified voltages. Higher voltages will damage control and could cause shock or fire hazard.
INSTALLATION
If the boiler manufacturer recommends a control location, follow such recommendations. If none is offered, the following informa- tion gives suggested locations.
When used for high limit service, the control should be in- stalled in the riser close to the boiler, or in a boiler tapping that is near the top or hottest section of the boiler. If the boiler is also used to heat domestic hot water, make sure that the high limit control is not located in the section of the boiler that contains the heat exchanger or piping for domestic hot water.
When used for low limit or operator service, the control should be located near that section of the boiler that contains the heat exchanger or piping for domestic hot water.
To remove the well from the control, loosen the set screw in the large nut, then slide the well off to expose the bulb. Screw the well into the proper tapping. Slide the bulb back into the well, making sure that the bulb enters the well as far as it will go and tighten the set screw.
CAUTION
Do not dent or bend the bulb as this will prevent it from fitting into the well properly.
