Bulb and Capillary Thermostat
Installation, Operation, and Maintenance Instructions
1.0 Handling
1.1 Handle with care to avoid damage to thermostat terminals,
capillary tube, and sensing bulb
1.2 Refer to Application Data link for additional information
related to system design and use instructions
2.0 Safety
2.1 WARNING: Make sure power supply is turned off before
installation or service of thermostat to prevent electrical
shock or damage to equipment.
2.2 WARNING: Circuit should have separate disconnect means
which shall be capable of being locked in the open position
and also in sight from the thermostat and heater system.
2.3 WARNING: Wiring must conform to the National Electric
Code and Local Regulations and should be performed by a
a qualified electrician. Make sure wiring is of a suitable
temperature rating, amperage rating, and the location.
2.4 WARNING: When servicing, handle with caution, heater(s)
that are installed near the thermostat bulb may be hot.
2.5 WARNING: Thermostat switch body should be installed in a
suitable enclosure.
3.0 Installation and Operation
3.1 Caution: Make sure the supply voltage is the is within the
rated voltage of the thermostat.
3.2 Caution: Thermostat switch frame should be properly
grounded to prevent electrical shock hazard
3.3 Make sure the amperage load to be switched by the
thermostat is within the amperage rating of the thermostat
at the applied voltage. Amperage loads exceeding the
thermostat rating must be switched through an additional
contactor or relay
3.4 Make sure that no dripping from condensation on cold water
pipes or other sources can fall on any exposed electrical
wiring connections or components.
3.5 Terminations should be properly tightened and connected
to hook-up wiring. A loose connection will result in over-
heating at the connection and could lead to premature
failure.
4.0 Maintenance
4.1 For most applications, no thermostat maintenance is
required.
4.2 Disconnect line switch prior to any testing or work on the
thermostat.
4.3 Recheck wiring periodically to ensure wiring has not become
damaged, worn, or loose due to vibration or other
application related conditions. Tighten, repair, or replace
as needed.
5.0 Trouble Shooting
5.1 WARNING: Disconnect power supply to thermostat before
performing any trouble shooting procedures.
5.2 Check supply voltage to thermostat to ensure there is
power.
5.3 Check wiring circuit- make sure thermostat is properly
wired.
5.4 Check continuity with a meter- thermostat should open and
close at the set point temperature (allow for tolerance).
