Installation
NOTE: Reference numbers and letters in parentheses in
the text refer to the callouts in the figures and in the
parts drawing.
Grounding
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
See F
IG
. 1. Loosen the grounding screw (GS). Insert
one end of a 12 ga. minimum ground wire behind the
grounding screw and tighten the screw securely.
Connect ground clamp to a true earth ground. A ground
wire and clamp, Part 238909, is available from Graco.
Air Requirements
Typical air requirements for continuous use at 400 rpm
and 100 psi (0.7 MPa, 7 bar) inlet pressure:
•
low viscosity air motor -- 12 scfm (0.34 m
3
/min)
•
high viscosity air motor -- 22 scfm (0.62 m
3
/min)
Air Line Accessories
Install the following accessories in the order shown in
F
IG
. 2, using adapters as necessary.
Bleed-type master air valve (A): to isolate the air line
components for servicing.
Air filter (B): removes harmful dirt and moisture from
the compressed air supply. Order part 106148 for
3/8 npt or 106149 for 1/2 npt.
Air regulator and gauge (C): to control air motor and
agitator speed.
Air line lubricator (D): Downstream from the filter,
install an air line lubricator for automatic air motor lubri-
cation. Set the lubricator feed rate at 1 drop of oil per
minute for high speed or continuous duty usage. Do not
overfeed oil or exhaust air may become contaminated.
To manually lubricate the air motor, see Lubricate the
Air Motor, page 6. A 3/8 in. npt air line lubricator, Part
214847, is available from Graco.
