Installation
Automatic Pressure Relief Valves
(continued)
Two drainage bottle kits (38) are included with wall
models (unassembled) and stand mount models
(assembled) to catch the drainage if the automatic
pressure relief valves (18) open.
For the wall mount models, assemble the kit as shown
in Fig. 5, page 11, and mount it securely to a wall or
bracket. Use the tie wrap, supplied, to hold the hoses
out of the way if necessary.
WARNING
INJECTION HAZARD
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 spurt of
pressurized fluid.
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. 76.
For 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. 6.
2. Connect the hardener supply hose (DD) to the
3/4 npt swivel inlet (37A) for the hardener displace-
ment pump. See Fig. 6.
For 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. 7.
2. Connect the hardener supply hose (DD) to the 3/4
npt swivel inlet (37) for the center (hardener)
displacement pump. See Fig. 7.
Additional System Components
Install and connect the feed pumps, solvent pump,
heaters, etc. Refer to the Typical Installations page 7
and Accessories on pages 40 and 41 for parts informa-
tion.
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 on page 41.
