NOTE: For most steps, if no figure drawing is refer-
enced, see Fig. 1 to locate the parts.
I .
Mount the system.
1. Secure the sprayer stand (301) to the floor in a
suitable location. See the mounting hole diagram
in manual 307551.
2. Install a bleed-type master air shutoff valve (1),
Part No. 113218, on the main air supply line to
provide a remote shutoff point for all air-powered
components, and a main line air filter (2), Part No.
106149, to remove harmful dirt and moisture from
the compressed air supply.
3. When operating the proportioning pump at the
higher pressure ranges, replace the Y-strainer
(318) with a higher capacity Y-strainer, Part No.
101078. The replacement filter is Part No. 180199.
NOTE: The air to the spray gun must be very clean
and dry to avoid contaminating the foam.
CAUTION
To avoid mixing the polyurethane foam chemicals
and permanently damaging the hoses, all critical air
and fluid connections are clearly labeled ISO or RES.
Make only ISO to ISO and RES to RES connections.

4. Install the 1:1 ratio feed pumps (3) in 55 gallon
drums of ISO and RES. Order Part No. 226946 for
the pumps, and Part No. 217381 for the Feed
Pump Kit which includes an Air Dryer, two 1:1
Fast–Flo pumps, two feed hoses, three air hoses,
and the related fittings. Manual 307552 contains
installation and operation information.
a. Screw the bung adapter (4) and pump tightly
into the drum cover. Then tighten the nut (5)
firmly to complete the air-tight seal. See Fig. 2.
b. Separate the ISO/RES identification label (6)
along the perforation. Clean the surface of the
air motor with solvent and apply the appropri-
ate label (RES or ISO) to identify the chemical
being pumped.
c. We recommend installing an air regulator near
the feed pump air inlet to control pump speed.
Remove the air valve (7). Install the regulator
and pin fitting using suitable adapters and
thread sealant on the male threads. Order Part
No. 206199 for an air regulator and gauge.
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of a container rupture and
serious injury:
D Never pressurize a drum or container that will
not withstand 5.5 psi (38 kPa, 0.38 bar) working
pressure.
D Never use a damaged drum of ISO or RES with
the Air Dryer.
5. Mount the Air Dryer (9) in a suitable location near
the ISO and RES drums. See Fig. 1. Order Graco
Part No. 217341, if you did not order the Feed
Pump Kit mentioned in Step 4. See the mounting
hole diagram in manual 307548.
a. Fill the bowl of the desiccant dryer. Unscrew
the ring (10) to remove the dryer bowl.
b. Remove the filter from the top of the bowl and
fill the bowl with the desiccant crystals pro-
vided with the kit. Reinstall the filter and bowl.
