Installation - Graco Husky 205 D110 Series Instructions Manual

Tightening Threaded Fasteners Before First
Use
Before using the pump for the first time, check and
retorque all external fasteners. See Torque Sequence,
page 18. After the first day of operation, retorque the
fasteners. Although pump use varies, a general guideline
is to retorque fasteners every two months.
Use a compatible thread sealant on all male threads.
Tighten all connections firmly to avoid air or fluid leaks.
CAUTION
To avoid pump damage, do not overtighten the
fittings to the pump.
Grounding
WARNING
FIRE AND EXPLOSION HAZARD
This pump must be grounded. Before
you operate the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 3.
The acetal pump contains stainless steel fibers which
make the wetted parts conductive. Attaching the
ground wire to one of the grounding locations
grounds the wetted parts.
The polypropylene and PVDF pumps are not
conductive. When you pump conductive flammable
fluids, always ground the entire fluid system by
making sure the fluid has an electrical path to a true
earth ground. See F . 1. Never use a polypropylene
IG
or PVDF pump with non-conductive flammable fluids
as specified by your local fire protection code.
Consult your fluid supplier to determine the
conductivity or resistivity of your fluid.
US Code (NFPA 77 Static Electricity) recommends a
conductivity greater than 50 x 10
(mhos/meter) over your operating temperature range
to reduce the hazard of fire. Consult your fluid
supplier to determine the conductivity or resistivity of
your fluid. The resistivity must be less than 2 x 10
ohm-centimeters.
To reduce the risk of static sparking, ground the pump
and all other equipment used or located in the pumping
area. Check your local electrical code for detailed
grounding instructions for your area and type of
equipment.

Acetal Pump Grounding Instructions
For polypropylene and PVDF pumps, see the warning
above.
Ground all of this equipment.
Pump: Connect a ground wire (A) and clamp, Part No.
222011. See F . 1. The pump grounding locations are
IG
on the manifold between the inlet and outlet ports. Use
the nut (B) and bolt (C) that are provided with the pump,
and install as follows:
1. Place the nut in the nut catcher on the underside of
the manifold.
2. Insert the bolt through the loop end of the ground
wire.
3. Insert the bolt through the hole on the pump manifold
and tighten it into the nut that you positioned in
step 1.
4. Connect the clamp end of the ground wire to a true
earth ground.

•
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 the manufacturer's
recommendations.
•
All solvent pails used when flushing: Follow the local
code. Use only grounded metal pails, which are
conductive. Do not place the pail on a
non-conductive surface, such as paper or cardboard,
which interrupts the grounding continuity.
•
Fluid supply container: Follow the local code.
