3. Connect large suction hose to inlet tube fitting of pump. Secure with hose clamp on plastic
sleeve supplied.
4. Connect small return tube to relief valve tube fitting on bottom of catalyst accumulator.
5. Place MEKP Catalyst container on floor below catalyst pump. MEKP must be lower than pump.
6. With upper quick pin removed and packing nut loose, if applicable, operate catalyst pump by
hand using the priming knob only. Catalyst should start to move up suction tube to pump.
NOTE: It may be necessary to wet seal surfaces of the pump to start fluid moving. This can be
accomplished by elevating the catalyst jug above inlet body of the pump and letting a small
amount of catalyst run down the tube to the inlet of pump, then make one or two strokes with
the pump.
7. Return catalyst jug to the floor and continue pumping until catalyst has reached a point in the
suction tube 1 to 2 inches from the inlet of the pump. Stop pumping action and place MEKP
container in jug bracket at side of resin pump.
8. Position suction tubes so they form an arc between jug and pump. The crown of the arc should
be higher than the catalyst jug and inlet of pump.
CAUTION: The suction tubes must be held in this position at all times insuring that the air
bubble in suction tube does not get drawn into catalyst pump. Air in catalyst pump can cause
improper catalyzation.
NOTE: The bubble may be as long as 8 inches and still function properly. With time, bubble will
grow longer as catalyst gases off. The bubble gives a visual indication that catalyst pump is
taking in material. With each up stroke of pump, the bubble will move forward toward pump.
With each down stroke, bubble will return to its original position. Mark the position of the
bubble by placing the black rings at each end of the bubble.
9. With jug and suction tubes in position and catalyst to the inlet of the catalyst pump, tilt catalyst
pump toward resin pump so that the outlet of the pump becomes the highest point in the
system. Operate pump by hand until fluid is emitted from outlet on both strokes of the pump.
NOTE: Be certain that all air is removed from catalyst pump to prevent air lock of pump. Air
lock of pump will result in improper catalyzation.
10. When all air has been purged from pump, connect the catalyst hose to the accumulator.
CAUTION: check all hoses and connections to insure a pressure tight seal.
11. With hose connected to pump and gun, make sure ball valve to power head of resin pump is
closed. Open needles of gun head.
12. Operate catalyst pump by hand until an even, steady flow of material emerges from gun.
NOTE: A suitable container will be required under gun.
13. Close needles of gun and flush solvent through mix chamber to clean out resin and catalyst.
