Hitachi 222104 important safety instructions Installation

Installation

DWall Bracket: Use the wall bracket (J) for wall mounting the Universal pump. This wall bracket is sized to fit any Graco pump designed to use a 2-in. bung adapter. Order Part No. 203987.

DRunaway Valve: Install a pump runaway valve to shut off the air to the pump when the pump acceler- ates beyond the pre-adjusted setting. A pump that is in a runaway condition can be seriously dam- aged.

CAUTION

Never allow the pump to run dry of the fluid being pumped. A dry pump quickly accelerates to a high speed, possibly damaging itself, and it may get very hot.

DBleed-Type Master Air Valve: Install a bleed-type master air valve (E) to relieve air trapped between it and the motor when the valve is closed. To order a 300 psi (2.1 MPa, 21 bar), 1/4-in. npt(f) bleed-type master air valve, order Part No. 110223.

DSuction Kit: The suction kit (L) is for use with the wall-mounted Universal pump, and it includes a drum tube and hose. To order a suction kit, order Part No. 213099.

DAir Motor Lubricator: The air motor lubricator (D) provides automatic air motor lubrication. To order a 250 psi (1.7 MPa, 17.4 bar) 1/4-in. npt(f) air motor lubricator, order Part No. 110148.

DAir Regulator and Gauge: Use the air regulator and gauge (C) to control air pressure and pump speed. To order a 0 to 200 psi (0 to 1.4 MPa, 0 to 14 bar) regulated pressure range (300 psi [2.1 MPa,

21 bar] maximum), 1/4-in npt(f) air regulator and gauge, order Part No. 110147.

DAir Filter: The air filter (B) removes harmful dirt and moisture from the compressed air supply. To order a 300 psi (2.1 MPa, 21 bar), 1/4-in npt(f) air filter (20-micron element), order Part No. 110146.

DAir and Fluid Shutoff Valves: Install air shutoff valves (A) and fluid shutoff valves (H) as shown to isolate the pump while you are servicing it.

DQuick-Disconnect Coupler and Nipple: The quick- disconnect coupler and nipple (not shown) are used to quickly disconnect the air supply. Attach the coupler (Part No. 208536) to the pump air inlet hose, and install the nipple (Part No. 169970) to the pump air inlet (P).

DThermal Relief Kit: Install the thermal relief kit on the dispensing valve side of the pump to assist in relieving pressure in the pump, hose, and dispens- ing valve due to heat expansion. To order a 600 psi (4.2 MPa, 41 bar) Thermal Relief Kit, order Part No. 237601.
