Page 4: Pressure Relief Procedure
Warnings Pressure Relief Procedure Follow the Pressure Relief Procedure whenever you see this symbol. This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop pumping and before cleaning, checking or servicing the equipment. - Page 5 Setup Setup NOTICE Any pressure applied to the pump inlet has the potential to cause unrestricted flow from the pump outlet even in a pump that is at rest or adjusted for zero stroke. To pre- vent this from happening, install a check valve of a com- parable pressure rating at the pump outlet.

Setup Connecting Lube Lines to Pump: Suction, Alarm Models Only: Installing Pressure Gravity and Pressure Fed Pump Models Switch (see Alarm Pump, page 17) Only The pump’s check valve is monitored by a pressure switch. When fluid pressure reaches the check valve NOTE: The lube line refers to the outlet line supplying cracking pressure lubricant to the lubrication points. - Page 9 Setup 3. For Suction Fed and Gravity Fed models only: Calculating Output Capacity With the lubricator operating, count the drops from The number of drops observed falling in the sight well the drip tube (4) falling into the sight well (2) for one equals the amount of oil discharged by the pump.
