Auto-Fill Shut Off (S)
The Auto-Fill Shut Off (S) is used for refilling the grease
tank/reservoir in an automatic lubrication system.
NOTE:
For systems without a fill valve, see
Refilling
Systems without a Fill Valve
instructions beginning on
page 13. For systems with a fill valve, see
Refilling
Systems with a Fill Valve
beginning on page 14.
As grease is added to the reservoir, it pushes the dia-
phragm up to the top of the reservoir. The diaphragm
then pushes the valve pin and closes the inlet fluid path.
When the fluid refilling path closes, the refilling line (D)
pressurizes and brings the refilling pump (P) to a pres-
surized stall condition.
NOTE:
The operator must monitor system while filling
tank to reduce the risk of accidental fluid overflow.
Refilling the Reservoir
Refilling Systems without a Fill Valve
1. Connect refilling line (D) from remote filling station
pump (P) to the Auto-fill Shutoff inlet (F
. 2, page
7).
2. Turn on remote filling station pump (P) and fill reser-
voir (K) until the indicator pin on the Auto-Fill Valve
(S) pushes up as shown in F
. 10. Pressure in the
refill pump (P) builds and the pump stalls.
3. Turn off air supply to refill pump (P).
4. Relieve pressure between the remote filling station
pump (P) and the Auto-Fill Shut Off (S):
a. Open ball valve (bv) (F
. 11). Pressure will be
released and excess fluid will drain out of the
drain tube (dt) and into the lubrication collection
container (N).
