INSTALLATION
Remove the top mounted 2” and ¾” bung plug from the clo ed head teel drum. The cu tomer- upplied drum mu t
meet UN1A1/X1.8/300 pecification and be con tructed entirely of 16 gauge teel or tronger.
1. In tall the Dual-Force Vac
pump into the ¾” bung hole in the drum. The lower tainle teel float valve portion
of the pump rotate independently of the top part of the pump. Thi aid in the in tallation of the pump, or
when moving the pump from drum to drum without having to di connect the air upply ho e. U e a 1
1/8
"
open-end wrench to tighten the lower portion of the pump onto the drum. The top part of the pump i now free
to rotate o the ball valve can be po itioned in the mo t convenient location.
2. Attach the compre ed air filter (#701S-24A) to the Dual-Force pump u ing the pipe fitting upplied. (Air flow arrow
mu t point to the Dual-Force pump.)
3. Connect your compre ed air upply ho e (3/8" in ide diameter minimum) to the compre ed air filter (3/8” NPT).
4. In tall the 36" long aluminum evacuation tube into the 2" bung hole. Carefully crew the black polypropylene
fitting at the end of the tube into the hole in the drum.
5. Attach the cam-lever coupling on the 10' long conveying ho e to the black polypropylene fitting on the drum.
Be ure both lever are engaged in the up po ition and that the conveying ho e i ecurely attached to the drum.
6. Fit the 19" wand into the cuffed end of the conveying ho e.
FILLING THE DRUM
1. Rotate the knob on top of the pump counter-clockwi e 1/4 turn until the knob pop up.
2. Open the bra ball valve to operate the unit. Immer e the end of the wand into the liquid to be picked up.
3. The top of the drum will “pop” inward a the vacuum i created and the liquid tart to fill the drum. A the
drum reache maximum capacity, the float valve on the pump will i olate the drum interior from the Dual-Force
Vac and the liquid flow will top. A mall amount of liquid may be expelled out the bottom of the Dual-Force
Vac before the float valve completely clo e . Shut off the bra ball valve to top the compre ed air flow.
EMPTYING THE DRUM
1. Pu h the knob on the top of the pump down and rotate it 1/4 turn clockwi e until it lock in po ition.
2. Be ure the conveying ho e i ecurely attached to the drum fitting.
DO NOT RESTRICT OR IN ANY WAY BLOCK THE FLOW OF LIQUID FROM THE CONVEYING HOSE.
3. Slowly open the bra ball valve.
4. The top of the drum will “pop” outward a the drum i pre urized and liquid tart to flow from the
conveying ho e. The drum i pre urized to a maximum of 8 PSIG and i held at thi pre ure by the pre ure
relief valve.
5. To top operation, clo e the bra ball valve and lowly rotate the knob on top of the Dual-Force Vac to the
“FILL” po ition. Thi will aid in venting re idual pre ure in the drum and top the flow of liquid.
CLEANING THE DUAL-FORCE VAC PUMP ASSEMBLY
1. Remove the Dual-Force Vac from the drum and remove the compre ed air filter.
2. Turn the knob to the “FILL” po ition.
3. With a 9/16" open-end wrench, un crew the bra pipe nipple and ball valve from the ide of the pump. Remove
the 3 houlder crew .
4. Lift the cap a embly off the pump body, and pull the float valve a embly from the bottom of the pump.
5. Un crew the hex barrel from the pump body.
6. Remove the three-lobed centering ring and rubber pacer. Carefully remove the red and/or green him from
the hex barrel.
7. Thoroughly clean the part in olvent and dry with compre ed air.
8. The float valve a embly and the cap a embly hould be in pected. Verify that the float move freely in ide
the tainle teel guide tube and that the O-ring i attached to the float.
9. The guide rod hould move freely in the cap a embly (approximately 39/64" axial travel) and the poppet
hould move freely on the guide rod (approximately 27/32" axial travel).
