•Before starting work, make sure that the air compressor is shut off.
1)
Connect an air valve, air filter, regulator and if necessary lubricator (hereinafter called the
"peripheral equipment") to hose which connected to compressor.
Refer (NOTE) for detail information.
2) Install these peripheral items supported by brackets, etc., near the pump.
3) Connect the hose from the peripheral equipment to the air valve of the pump's supply port.

•Use a flexible hose to absorb pump vibration, and ground the hose.
•Make sure that there will be no external force on any connection part of the pump.
Be especially careful not to have the pump support part of the weight of the hose and the piping.
•The piping and the peripheral equipment may become clogged with sludge.
Clean the inside of the piping for 10 to 20 seconds before connecting it to the pump.
•Be sure to sufficiently ground the piping and peripheral equipment.

Note:
•So that sufficient air can be supplied to meet the needs of the pump, the diameter of the piping should be the
same as the diameter of the supply port of the pump. Also choose peripheral equipment with sufficient airflow
to meet the requirement of air consumption of the pump. Also must be considered usage and stability of air
pressure. Also must be installed it nearest position of pump unit.
•If you use a solenoid valve as the air valve, be sure it is a three-way valve.
When the valve is closed, the internal compressed air of the pump will be released, and this will switch
the spool to its normal position.
•Use of a coupler for the connection part of each hose will make operation and maintenance easier.
•In case of intermitted operation, lubrication is not required during operation. However when pump is
operating by dry air and in case of continuous operation and/or transferring high temperature liquid
(exceeded 70˚C ), lubrication must be required.
Must be used turbine oil none addition class 1 turbine oil (equivalent ISO VG 32 grade) for lubricants.
Adjust lubricator to supply minimum amount of oil to pump unit.
Note: DP-F series are not required lubrication even using dry air.
