System Shutdown
ThermoJet Oil Purifiers are equipped with a timing relay which delays cessation of oil flow for 2 minutes after
the power selector switch has been transferred from the ON to the OFF position. The purpose of this delay is
to allow sufficient time for the oil heater to “cool down.” During this cooling interval the oil heater is inoperable
and the oil temperature will decrease. At the end of the 2 minute delay the motor will stop running and the
pump will cease to operated, and the oil pressure will falls to zero.
To shut down the system,1) turn the selector switch form the ON to the OFF position, 2) allow the system to
operate until the motor turns off, 3) turn the main disconnect switch from the ON to the OFF position.
