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.

–11 AND –11-FS OPTION (for Mechanical Lubricators): See Figure 3

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.
