INSTALLATION INSTRUCTIONS FOR MODEL KPS OIL LEVEL SWITCH
WITH ADAPTERS (INCLUDING HIGH PRESSURE MODELS)
Note: For fire safe oil level controllers (KPS-FS) see additional instructions in this work sheet covering installation of fire safe
valves.
PNEUMATIC SWITCH INSTALLATION:
• Connect the supply line of air pressure to the ¼” pipe thread located at the top of the air valve (D)
Note: Acceptable air pressure range is 10 psi to 100 psi. Air pressure greater than 100 psi will prevent the switch from operating.
• The exhaust vent is located at the base of the air valve (E) and is 1/8” pipe thread.
Note: If an exhaust line is used to carry gas away from the pneumatic switch, this line must be short, undamaged and trap free.
COMMON PROBLEMS AND SOLUTIONS
• Leaking switch may be caused by dirt. Wash the assembly in solvent to remove any foreign material.
• The switch is not tripping. Check for excessive restriction from a long exhaust line, a damaged line or a line with moisture
traps, or excessive pressure from the supply line.
• The switch is not properly tripping. Check the pressure coming into the switch. The switch may need adjustment. See below:
PNEUMATIC SWITCH ADJUSTMENT: The switch is factory set at 60 psi with a trip point of 5/8” to ¾” oil drop.
• Remove the controller from the housing.
• Connect the supply pressure to the pneumatic valve (D).
• With the switch float arm against the magnet, adjust screw (C) until there is no leakage from the pneumatic valve.
• To adjust for a higher or lower level release lock nut (A) and backing screw (B) out.
• For a lower level, turn screw (B) in and readjust screw (C).
Note: Screw (C) must be adjusted until there is no leakage from the valve with the float assembly resting against the magnet.

OIL LEVEL CONTROLLERS WITH –9 (Universal adapter), -10(Slotted universal adapter), -12 (Pole mounted adapter) AND –
FS OPTIONS
• Set the controller so that the centerline of the sight window corresponds to the desired oil level in the crankcase.
• Mount the controller close to the crankcase and connect the hose from the ¾” outlet located on the controller to the crankcase.
NOTE: The outlet port on the oil level controller must be located below the oil level in the crankcase.
• An equalizing line must be used between the controller and crankcase in order to equalize the pressure. The tubing must be a
minimum of 1/2” I.D. and must be kept under 2 feet. DO NOT loop this line. It must be trap free and self draining, with a
downward pitch flow by gravity.

Drill holes in the lubricator housing as shown, and mount
the controller with the inlet located on the top side using the
seal washers and mounting bolts provided.
• Place the seal washers between the controller and the
lubricator housing.
OIL LEVEL CONTROLLER WITH
• Remove the triangular blind flange located on the compressor and mount the controller assembly in its place.
• NOTE: It is important to install a drain line between the drain outlet of the compressor and the controller.

• Remove the cast aluminum inspection door from the engine. Remove the clamp bar from the old door.
• For –17, -18, -37, -38 install the o-ring into the groove of the Kenco door and replace the clamp bar on the back side of the door
using the 5/8” bolts, washers, and o-rings supplied by Kenco.
• For –27, install the o-ring into the groove of the Kenco door and replace the clamp bar on the back side of the door using the
7/16” bolts and the stat-o-seals supplied by Kenco.
• Install the equalizing line between the controller cover plate and the door (Tubing and connectors supplied by Kenco).
• Place the controller assembly into the inspection port of the engine and tighten the center bolt(s) down.
• Install oil inlet line into the controller oil valve or the meter inlet port.
• NOTE: For the –18 model, refer to the additional instructions supplied with the 1618 Kenco Low Flow meter.

• Remove the visual oil gauge assembly from the engine and replace it with the oil level controller and adapter assembly supplied
with a gasket and mounting bolts when applicable.
• If an equalizing exists for the engine sight glass and detach the equalizing line from the sight glass while still attached to the
engine.
• Install the oil controller and then reattach the equalizing line to the vent located at the top of the adapter.
Note: It is important to insure that there are no loops in this line for it must be trap free and self draining.

IV. INSTALLATION INSTRUCTIONS FOR FIRE SAFE VALVES: See Figure 5
MODEL 50-FS AND 75-FS (PATENT NO. 3,877,476)
NOTE: All lines between thermal valves, supply tanks and the controller must be made of steel. DO NOT use rubber hose. The
lines should be 3/4” I.D.
• The eutectic fuse element should always be in a downward position to help the element melt when heat is applied to the valve.
• The 50-FS valve has 1/2” FNPT threads and should be installed in the oil supply line as close to the controller as possible.
Meters, filters and pressure regulators should be installed between the controller and the 50-FS.
• The 75-FS valve has 3/4” FNPT threads and should be located as close to the crankcase as possible and the oil outlet line should
be a minimum ¾” I.D. to insure adequate oil flow to the crankcase.
NOTE: The 75-FS valve is not required when using –FS adapters other than –9 and –12.
FIGURE 5: FIRE SAFE VALVE INSTALLATION
V. START-UP PROCEDURES
• After the engine has been running for 1 hour, visually check the oil level in the sight glass. The oil level should be in the center
of the sight glass.
• With the engine running, check the crankcase oil level. It should be the same as the oil level in the oil controller. If not, check
the installation of the equalizing line (if applicable) see instruction for the equalizing line at –9.
• Check all piping connections for leaks and repair as needed.
VI .SIX MONTH SUGGESTED MAINTENANCE PLAN
Switch Service
• Test switches to insure that the switches are operating correctly.
• Shut the engine off.
• Disconnect the equalizing line (if applicable).
• Place a blunt rod through the vent hole on the cover plate and depress the oil float.
• Observe the engine panel to determine if air is released from the air valve.
• If the switch is functioning properly, replace the equalizing line or vent plug.
• If the switch does not function, it must be replaced (refer to a replacement parts list).
