To prevent the potential risk of static electricity ensure that free falling oil does not exceed 6 inches (150
mm). If the oil return level exceeds 6 inches (150 mm), insert a guide baffle to smooth out flow to the oil
surface in the reservoir.
Even if the Thermo
Jet
is to be installed temporarily, it should be hard-piped for safety reasons. Hoses are
acceptable if they are certified not to collapse under vacuum conditions and are rated for 600 PSIG (42 bar)
at 200
o
F (100
o
C).
Since all wetted parts of the Thermo
Jet
are constructed of type 300 stainless steel, it is recommended
(but not mandatory) that connecting hard pipe work is also stainless steel. In accordance with good piping
practice, the use of joints, bends, and unnecessary long pipe runs should be minimized. Elevated sections
of suction piping in horizontal runs also must be avoided to prevent air pockets from existing.
Connect the suction line to the reservoir low point drain, or to existing purifier connections if the reservoir is
constructed in accordance with API 614.
When a flooded suction is provided to the ThermoJet Oil Purifier, recommended practice is to install a
manual shut-off valve (if one does not already exist) directly onto the reservoir connection routed to the
Thermo
Jet
inlet connection.
If the oil reservoir is located below the Thermo
Jet
oil inlet connection, a manual shut-off valve is not
required or desirable since it creates a line restriction unnecessarily.
The discharge line should be connected above the oil surface and at the opposite end of the reservoir
versus the suction connection to ensure optimum circulation of oil through the Thermo
Jet
. An oil purifier
return connection will exist if the reservoir is constructed in accordance with API 614.
Choose a central convenient location, allowing enough room to connect oil supply and return piping and
electrical services. Ensure that unrestricted operator access is maintained at the front of the unit when the
cabinet door is open for system operation and ease of access to the electrical control enclosure.
The ThermoJet Oil Purifier has maintenance access doors on the front of the cabinet. Ensure that
unrestricted access is provided for system troubleshooting and maintenance.
NOTICE:
Ensure that the supply connection to the ThermoJet Oil Purifier is not
adjacent to or near any oil return connection in the oil reservoir being
services. This could result in oil frothing.
NOTICE:
Do not install any valves or other restrictive devices in the discharge
line which could cause back flow and flooding of the unit..
