Preface
Be careful to minimize flow restrictions. Do not close any downstream valve during normal operation without
adding external relief protection. A resulting pressure spike could cause filter damage and/or personal injury. If a
downstream valve must be used, this valve must be locked in the open position during MFS operation.
The MFS is to be used solely for the purpose of providing auxiliary filtration. It is not intended to be used as a
power unit or in conjunction with other components for the purpose of performing work.
▪ Never start up or run a dry pump. This will cause galling, seizing or destructive wear between the rotors,
end plates and casting.
▪ The Mobile Filtration System is designed for the transfer and filtering of hydraulic and lubrication oils only.
It is not to be used for highly volatile fluids such as gasoline or paint thinners. Please contact factory for uses
other than those specified.
▪ The maximum operating temperature for the MFS is 150° F. Higher temperatures could damage the hoses.
▪ Since minimum repair service is generally required on these units, it is recommended that any failed parts
be replaced with new parts. See the replacement parts list in section 5.
▪ Electric motor warnings for the 1 ½ HP model is as follows:
- 1 ½ HP electric motor draws 12.6/6.3 amps at 115/230 volts, 60 Hz at full load. Starting current is
approximately 88/44 amps at 115/230 volts, 60 Hz. A proper circuit breaker should be installed to protect the
motor and meet national and local electric codes. Recommended size for an extension cable is 12-3 conductor
with a maximum length of 25 feet.

Connecting the MFS to the fluid reservoir
NOTE
Black hoses with quick disconnects are supplied with
MFS model 1148220.
(Quick disconnect Wands are sold separately - 1148220)
Clear hoses and wands are supplied with
MFS model 1131722.
1. Connect the supplied inlet hose to the inlet port on the MFS. Then connect the inlet hose to the reservoir quick
disconnect, or connect the wand to the inlet hose and place tube inside reservoir opening.
2. Connect the supplied outlet hose to the outlet port on the MFS. Then connect the outlet hose to the reservoir
quick disconnect, or connect the connector tube to the outlet hose and place tube inside reservoir opening.
3. Check that the power source being utilized complies with the requirements of the filtration cart motor before
actual hook-up.
4. Switch on the Mobile Filtration System’s motor. Visually check that the fluid is actually being pumped through
the MFS and out of the outlet hose.
