Mounting; Grounding - Graco Husky 1050 Operation

Mounting

• The pump exhaust air may contain contaminants.
Ventilate to a remote area. See Air Exhaust
Ventilation on page 11.
• Never move or lift a pump under pressure. If
dropped, the fluid section may rupture. Always
follow the Pressure Relief Procedure on page 16
before moving or lifting the pump.
1. For wall mounting, order Graco Kit 24C637.
2. Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as well
as the stress caused during operation.
3. For all mountings, be sure the pump is bolted
directly to the mounting surface.
4. For ease of operation and service, mount the pump
so air valve, air inlet, fluid inlet and fluid outlet ports
are easily accessible.
5. Rubber Foot Mounting Kit 236452 is available to
reduce noise and vibration during operation.
6. Prolonged exposure to UV radiation will degrade
natural polypropylene components of the pumps. To
prevent potential injury or equipment damage, do
not expose pump or the plastic components to direct
sunlight for prolonged periods.

Grounding

The equipment must be grounded to reduce the risk of
static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
Pump: See F . 1. Loosen the grounding screw (GS).
IG
Insert one end of a 12 ga. minimum ground wire (R)
behind the grounding screw and tighten the screw
securely. Do not exceed 15 in-lb (1.7 N•m). Connect the
clamp end of the ground wire to a true earth ground. A
ground wire and clamp, Part 238909, is available from
Graco.

Polypropylene and PVDF: Only aluminum,
conductive polypropylene, hastelloy, and stainless
steel pumps have a ground screw. Standard
polypropylene and PVDF pumps are not conductive.
Never use a non-conductive polypropylene or PVDF
pump with non-conductive flammable fluids. Follow
your local fire codes. When pumping conductive
flammable fluids, always ground the entire fluid
system as described.

IG
Air and fluid hoses: Use only grounded hoses with a
maximum of 500 ft (150 m) combined hose length to
ensure grounding continuity.
Air compressor: Follow manufacturer's
recommendations.
Fluid supply container: Follow local code.
Solvent pails used when flushing: Follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which interrupts
grounding continuity.
Check your system electrical continuity after the initial
installation, and then set up a regular schedule for
checking continuity to be sure proper grounding is
maintained.
