Installation
Automatic Pressure Relief Valves
(continued)
Fig. 6. Two drain bottle kits (B) are included with the
stand mount models to catch the drainage if the auto-
matic pressure relief valves (A) open.
WARNING
INJECTION HAZARD
Be sure to use the drain bottles and drain lines
provided. If system pressure is exceeded, fluid
emitted from the automatic pressure drain valves
may be at pressures over 3000 psi (21 MPa, 207
bar). To reduce the risk of serious injury from fluid
injection or fluid splashing, make sure the drain
bottles are securely fastened to the frame or wall
so that they can handle a sudden discharge of
pressurized fluid. Discharged fluid on floors can
also cause a slipping hazard if not collected.
Connect Fluid Supply Hoses
NOTE: If you mount the pump on a wall, turn the
displacement pump inlet assemblies (CC) to face
forward, rather than backwards as shown in Fig. 7.
Two Displacement Pump Models
1. Connect the resin supply hose (EE) to the 3/4 npt
swivel inlet (37B) for the resin displacement pump.
See Fig. 7.
2. Connect the hardener supply hose (DD) to the
3/4 npt swivel inlet (37A) for the hardener displace-
ment pump. See Fig. 7.
Three Displacement Pump Models
1. Connect the resin supply hose (EE) to the 3/4 npt
swivel inlet (37B) for the resin displacement
pumps. See Fig. 8.
2. Connect the hardener supply hose (DD) to the 3/4
npt swivel inlet (37) for the center (hardener)
displacement pump. See Fig. 8.
Additional System Components
Install and connect the feed pumps, solvent pump,
heaters, etc. Refer to the Typical Installations
(pages 7, 8 and 9) for parts information.
Use a dry air kit or a nitrogen regulator kit to protect
the fluid in the supply containers from moisture that
can crystallize the fluid and cause the ball checks to
malfunction. See Accessories in Configurator Product
