Draining and Cleaning Procedures
Draining and cleaning procedures must be practiced if the ThermoJet is being used to remove
water contaminant in different type of oil and from different reservoirs. The following procedures
are listed in order of criticality. Depending upon any variety of individual situations, they may be
either followed to conclusion, modified as desired, or discontinued at any point.
1. Shut off the reservoir drain valve; energize the motor so that the major portion of oil in the
system can be pumped out within a few minutes. Piping must have an atmospheric vent in
order for air to enter the piping system. If the suction and the discharge hoses were attached
to the portable unit, care must be taken to ensure that oil in these lines are pumped out.
2. Remove the drain cap from the separation vessel and drain the oil into a suitable container.
3. To drain the oil from the filter housing, remove the air vent screw located on the top of the
filter housing to prevent siphoning of oil out of the heater tube. Then open the drain valve at
the bottom of the filter housing and allow the oil to drain into a suitable container.
4. To drain the heater vessel, open the drain valve and drain the oil into a suitable container.
5. Remove the oil filter element and install a new one.
6. Remove the screen from the Y-strainer and clean it.
7. If preparing the unit for use on a significantly different type of oil, perform one or all of the
following procedures:
•
Connect the ThermoJet to a small supply of the next oil to be purified (minimum 20
gallons), and circulate the fresh oil to flush out the existing oil for a minimum of 15
minutes, or up to 60 minutes if the ThermoJet is especially dirty.
•
Connect the system to a supply of compatible solvent (or other cleaning agent) and
circulate to flush for a minimum of 15 minutes.
NOTICE:
This procedure allows the pumps to run “dry”, but it will not
damage them since they are lubricated with the residual oil.
However, this procedure should not continue for more than a few
minutes because the pump requires inlet oil to lubricate and cool
the gears of the pump, and the operator should be in attendance to
monitor it while draining the equipment.
NOTICE:
For many situations the above procedures are adequate for
removing most of the oil from the system in order to prepare the
ThermoJet for use on similar or compatible oil..
Do not use flammable cleaning solvents to flush
this system. Failure to do so may result in
serious injury or even death
