Make sure that the unit location is not in a confined space to ensure
proper air circulation. Special air circulation/ventilation is required
for units operating at temperatures exceeding 500ºF (260ºC).
Vapors can escape from areas such as the reservoir tank during
high temperature operation.
!
CAUTION
Harmful vapors may be generated from thermal fluid
during high temperature operation.
Prolonged or repeated exposure of these hot-generated
vapors may result in eye and respiratory tract irritation.
Avoid contact or inhaling harmful amounts of material.
Consult the Material Safety Data Sheet (MSDS) for
precautions and instructions for the thermal fluid you
are using.
Note: Before storing your TDH-6 temperature control unit, make
sure you remove all residual water with compressed air to
avoid a potential freezing hazard.
Note the following table of ambient temperature ranges permitted
for storage and operation:
Ambient storage range
ºF
-40ºF to 185ºF
-40ºC to 85ºC
You should preheat the process heat transfer fluid first if you want
to start the unit below an ambient temperature of 30ºF (-1ºC).
Make sure that all external piping is properly sized to reduce
external pressure drop as much as possible. Do not install process
or water supply/drain piping smaller than the fittings on the unit. If
the water supply piping is larger than unit fittings, reduce the pipe
size at the unit.
