Installation
5. Connect an air supply hose to the 1/4 npt air line
coupler (13). Air supply hoses (103) are supplied in
Kit 217381. See Fig 3, page 6.
6. Connect a fluid supply hose from the 3/4 npt(f) fluid
outlet of the ISO feed pump to the inlet fitting of the
ISO proportioning pump, using adapters as needed.
Then connect a fluid supply hose between the RES
feed pump and RES proportioning pump.
Grounding
Remove the ground screw (Z) and insert through eye of
ring terminal at the end of ground wire (Y). Fasten ground
screw back onto pump and tighten securely. See Fig 2.
Connect the other end of the wire to a true earth ground.
Order Part No. 222011 Ground Wire and Clamp.
Feed Pump Kit Installation
The following instructions assume you are using this kit
with a Graco Foam–Cat Sprayer.
1. Install the feed pumps as described in Steps 1–4, on
page 4.
2. Mount the Air Dryer (105) in any suitable location.
Refer to manual 307548 for the mounting hole
diagram. See Fig 3.
3. Unscrew the air dryer ring (F) to remove the bowl.
See Fig 3. Remove the filter and fill the bowl with the
desiccant, provided. Reassemble.
4. Install the drum fittings (H) in the 3/4 in. vent port of
the proper drum.
CAUTION
Be sure all hose connections in your polyurethane
foam spray system are clearly labeled ISO or RES
and make connections only with identically labeled
components to avoid material crossing.
Crossing polyurethane materials will cause the
material to harden in the equipment and may
permanently damage it.
WARNING
Static electricity is created by the high velocity flow of
fluid through the pump and hoses. If every part of the
spray system, and all objects in the spray area are not
properly grounded, the static electricity may cause
sparking. Sparks can ignite fumes from solvents and the
fluid being sprayed, dust particles, and other flammable
substances, causing a fire, explosion and serious bodily
injury and property damage.
To reduce the risk of static sparking, use only conductive
air and fluid hoses and be sure your entire system is
properly grounded. Ground the feed pumps as
explained below.
CAUTION
One end of each fluid hose and each drum nipple (G)
of the drum fittings (H) is labeled ISO or RES. Make
only ISO to ISO and RES to RES connections to avoid
material crossing.
