Installation; General Information; Grounding; Air Exhaust Ventilation - Graco HUSKY 715 Instructions-Parts List Manual

General Information

1. The TYPICAL INSTALLATIONS shown on pages
4–6 are only guides for selecting and installing sys-
tem components for all models except Model
223–747. Contact your Graco distributor or Graco
Technical Assistance (see back page) for assistance
in planning a system to suit your needs.
NOTE: For Model 223–747 only
308–035 for the Typical Installation and Installa-
tion instructions.
2. See pages 28 and 29 for ACCESSORIES available
from Graco. Always use Genuine Graco Parts and
Accessories.
3. Use a compatible thread sealant on all male threads.
Tighten all connections firmly to avoid air or fluid
leaks.
CAUTION
Do not overtighten the fittings to the pump, to avoid
pump damage.
4. Reference numbers in parentheses refer to the parts
drawings and lists on pages 19–27.

Grounding

WARNING
This pump must be grounded. The steps for
grounding may differ from the way you ground other
pumps. Read and carefully follow the text of FIRE
OR EXPLOSION HAZARD on page 3 before oper-
ating the pump.

Air Exhaust Ventilation

WARNING
Be sure to read and follow the warnings and precau-
tions regarding USING HAZARDOUS FLUIDS,
and FIRE OR EXPLOSION HAZARD on page 3,
before operating this pump.
Be sure the system is properly ventilated for your
type of installation. You must vent the exhaust to a
safe place, away from people, animals or food han-
dling areas when pumping flammable or hazardous
fluids.
The minimum size for the air exhaust hose is 3/8 in.
(9.5 mm) ID x 15 ft (4.57 m). If a longer hose is re-
quired, use a larger diameter hose. A void sharp
bends or kinks in the hose.
If the diaphragm ruptures, the fluid being pumped
will be exhausted with the air. Place a container at
the end of the air exhaust line to catch fluid in case
the diaphragm ruptures. See Fig 4 on page 5.

INSTALLATION

Mountings

1. The direction of the ports in the inlet and outlet mani-
, refer to manual
2. Be sure the mounting can support the weight of the
3. To mount the pump on a 55 gallon bung drum, use
4. For all other mountings, be sure the pump is secured
When Pumping High Density or Abrasive
Fluids
High density fluids prevent the lightweight
Buna–N check valve balls from seating properly , which
reduces pump performance significantly. Conversion Kit
224–217 includes stainless steel balls for such applica-
tions (see page 30). Refer to page 13 to change the balls.
For improved ball resistance to highly abrasive fluids
such as those containing frit or porcelain glaze, order Ce-
ramic Ball Kit 224–644 (see page 30).
CAUTION
The pump exhaust air may contain contaminants.
Ventilate to a remote area if the contaminants could
affect your fluid supply. See AIR EXHAUST VENTI-
LATION, to the left, and Fig 4 on page 5.

needs. A dual manifold is also available (refer to the

pump, hoses, and accessories, as well as the stress
caused during operation.
Bung Kit 221–094 (see page 28). Screw the bung
adapter, part no. 183–553, into the drum bung hole.
Screw the suction tube, part no. 183–549, into the
pump inlet manifold. Lower the pump and suction
tube through the bung adapter and into the drum.
Slide the feet on one side of the pump securely under
the drum rim. Refer to Fig 3.
with screws and nuts.
WARNING
To reduce the risk of serious injury, splashing in the
eyes or on the skin, and toxic fluid spills, NEVER
move or lift a pump under pressure. If dropped, the
fluid section may rupture. Always follow the Pres-
sure Relief Procedure Warning on page 3 before
moving or lifting the pump.
