AEC TDH-6 Series Operation And Installation Manual page 23

The reservoir tank must be vented to prevent pressurization.
A pressurized reservoir could rupture, allowing hot fluid
to escape and become a potential fire and slip hazard.
If you are routing the drain line to an open drain, make sure that
the line is directed away from personnel to avoid scalding.
Carefully select connecting lines and connectors between the TDH-6 unit
and the process to best meet the needs and requirements of your application.
Make sure lines and connectors have a service rating of
at least 100 psig (689.5 kPa/6.9 bars), and a temperature rating
at least equal to the maximum operating temperature of your 6017 unit.

CAUTION
Note: Heat transfer fluids expand when heated. Expansion rates
vary, depending on fluid types and temperatures. For more
information on expansion rates, refer to specification
information for the heat transfer fluid you select.
Generally, most heat transfer fluids expand at the rate of
2.5% for every increase of 50°F from temperatures above
60°F (16°C).
