INSTALLATION INSTRUCTIONS FOR MODEL KLC

OIL LEVEL CONTROLLERS WITH ADAPTERS (INCLUDING HIGH PRESSURE MODELS)

Note: For fire safe oil level controllers, see additional instructions in this work sheet covering installation of fire safe valves.

I. 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 controller inlet screen or filter.

 For HP-A high pressure models, pressure range must be between 10 psig and 35 psig. For HP-B high pressure models,

pressure range must be between 36 psig and 70 psig.

 The oil inlet valve is set to maintain the oil level at the center of the sight glass when oil inlet pressure is at midrange. 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 oil inlet head pressure and a maximum of 25’ of oil inlet head pressure.

II. INSTALLATION INSTRUCTIONS FOR UNITS WITH ADAPTERS:

OIL LEVEL CONTROLLERS WITH –9 (Universal adapter), -10 (Slotted universal adapter), -12 (Post mounted adapter) AND –
FS OPTIONS
 Attach the controller to the mounting adapter using the Kenco supplied bolts (and washers if applicable). The recommended

torque for the bolts is

 Mount the controller so that the centerline of the sight window corresponds to the running oil level in the crankcase. Connect

the hose from the ¾” outlet of 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 3/8” I.D. and must be kept under 2 feet. DO NOT
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.

 If an equalizing line exists for the engine sight glass, detach the equalizing line from the sight glass and reattach it to the vent

connection located at the top of the controller adapter.
