IsoGuard Select Fluid System Setup

Component A (Red) Pump: Fill IsoGuard Select reser-

voir (LR) with IsoGuard Select fluid (provided by Graco).

a. Lift the reservoir (LR) out of the bracket (RB)

and remove the container from the cap.

b. Fill with fresh fluid. Thread the reservoir onto

the cap assembly and place it in the

bracket (RB).

c. Push the supply tube approximately 1/3 of the

way into the reservoir. The supply tube is the

tube with the check valve with an arrow pointing

in the direction of flow towards the IsoGuard

Select fluid cylinder.

d. Push the return tube into the reservoir until it

reaches the bottom. The return tube is the tube

with the check valve with an arrow pointing in

the direction of flow away from the IsoGuard

Select fluid cylinder.

NOTE: The return tube must reach the bottom of the

reservoir to ensure that isocyanate crystals will settle to

the bottom and not be siphoned into the supply tube and

returned to the pump.
