Preface
Be careful to minimize ow restrictions. Do not close any downstream valve during normal operation without
adding external relief protection. A resulting pressure spike could cause lter 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 ltration. 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 ltering of hydraulic and lubrication oils only.
It is not to be used for highly volatile uids such as gasoline or paint thinners. Please contact factory for uses
other than those specied.
▪ 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.
1.0 Connecting the MFS to the uid 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 ltration cart motor before
actual hook-up.
4. Switch on the Mobile Filtration System’s motor. Visually check that the uid is actually being pumped through
the MFS and out of the outlet hose.

2.0 Achieving the best ltering e󰀩ciency
1. If not using the quick disconnect model, in order to ensure the proper cleaning of the reservoir uid, position
the ends of both the inlet and the outlet hose or wand as far apart as possible inside the reservoir preferably on
di󰀨erent sides of the existing ba󰀪es.
2. Cycle the hydraulic system thoroughly in order to ush the contaminated uid from the lines and system
components so all the uid in a system will be ltered through the MFS.
3. Operate the MFS until the total volume of the system uid passes through the MFS. Cycle the reservoir uid
through the MFS six to eight times to insure the total system uid is ltered completely.
3.0 Removing elements from the K9 housing
Equipment required: 1 ½” box end or socket wrench, a container to hold dirty elements and uid from the lter
housing, and a small cup of grease.
1. Remove lter housing cap using the 1 ½” wrench and inspect the O-ring(1264144).
2. Remove element(s), compression spring and spring plate. Separate elements (if there are stacked elements)
and retain the element connectors. Discard the elements.
3. Drain K9 lter housing.
3.1 Installing new or cleaned elements
1. Lubricate grommets located at each end of the replacement element(s).
NOTE: DO NOT USE GREASE LUBRICANT IF FIRE RESISTANT FLUIDS ARE UTILIZED IN THE SYSTEM.
2. If required, install connectors between elements. Then install spring plate and compression spring.
3. Install element(s) into the lter housing, making sure elements are positioned correctly on the bushing in the
porting head.
4. Secure lter cap to lter housing using the 1 ½” wrench.
NOTE
Filter elements require changeout when the
Dirt Alarm is registering in the red area.

4.0 Servicing the strainer
Under normal operating conditions, the strainer should be removed from the line, cleaned and re-installed
after every 100 hours of operation. The strainer should be cleaned more often however, if the uid is heavily
contaminated.
