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, the supply tanks and the controller must be made of steel. DO NOT use rubber hose.
The lines should be ½” 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 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 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.

V. START-UP PROCEDURES
•
Flush the supply system and supply line with solvent to remove all burrs and construction debris.
•
Insure that the oil supply tank is full.
•
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
Oil Valve Service
•
Close the oil supply valve and discount the oil inlet supply line.
•
Place a pan under the controller to catch the oil from the oil supply line.
•
Remove the inlet oil housing and clean the screen.
•
Once the screen is clean, reassemble and open the oil supply valve.
Note: Dispose of oil in a proper container.
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).
