INSTALLATION INSTRUCTIONS FOR MODEL KLCM OIL LEVEL CONTROLLERS WITH ADAPTERS

(INCLUDING HIGH PRESSURE MODELS)

Note: For fire safe oil level controllers (LCM-FS) see additional instructions in this work sheet covering installation of fire safe
valves.

Note: Switch trip point is factory set at a ¾” drop . For adjustment instructions, please consult the factory.

II. INSTALLATION AND MAINTENANCE INSTRUCTIONS FOR OIL INLET VALVE:

• Connect the oil supply line to the oil inlet on the oil level controller. The minimum recommended supply line is ¾” I.D. The
supply line must be clean and it is recommended that it be flushed with solvent before installation.

• Connect the oil supply line to the oil supply tank. If there is no existing valve at the tank or the existing supply outlet, a shut-off
valve should be placed in the line to prevent oil loss when cleaning the inlet screen or filter.

• For high pressure models HP-A, pressure range must be between 5 psi and 34 psi. For high pressure units HP­range must be between 35 psi and 70 psi.

• The oil inlet valve is adjusted to maintain the oil level at the center of the sight glass. Low or high levels are often caused by
two problems:

1. Excessive oil inlet pressure, which will cause the unit to overfill.

2. Improper equalizing lines between the crankcase and the controller will also result in improper levels.

Note: Low pressure models require a minimum of 2’ of head pressure and a maximum of 15’ of oil inlet head pressure.

• 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.

OIL LEVEL CONTROLLERS WITH –9 (Universal adapter),
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.
