Installation
The typical installation shown in F
. 1 is only a guide
for selecting and installing a hose reel system. The
components shown are the minimum requirements for
all systems. However, it is not an actual system design.
Contact your Graco Distributor for assistance in
designing a system to suit your needs.
NOTE: The air and fluid accessories required for your
pump must be properly sized to the pump. Refer to
your pump manual for selecting pump accessories.
Grounding
Pump:
follow manufacturer’s recommendations.
Hose reels:
connect to a true earth ground when
dispensing petroleum products. This can be done by
bolting the reel to a grounded structure, or by using a
conductive inlet hose to connect to a grounded piping
system.
Fluid hoses:
use only conductive hoses when
dispensing petroleum products.
Dispense valves:
use thread sealant when connecting
the meter to the hose. Do not use PTFE tape on the
pipe joints, as it may cause loss of ground across the
pipe joint.
Waste container while flushing:
use a grounded metal
container. Hold the hose coupling or metal part of the
meter firmly to the side of the waste container while
flushing.
Required Components
Be sure to have the following components before
beginning installation.
• Hose Inlet kits (L)
• Reel mounting bases, mounting brackets, and
mounting channels (P)
• Dispense valves (N)
A ground wire (G), bleed-type master air valve (E),
and fluid drain valve (H) are required in your system
installation. These components help reduce the risk
of serious injury, including fire and explosion,
injection, and splashing in your eyes or on the skin.
• The ground wire must be connected to the pump
grounding lug and to a true earth ground
according to your local codes.
• The bleed-type master air valve relieves air
trapped between this valve and the pump after
the air is shut off. Trapped air can cause the
pump to cycle unexpectedly. Locate the valve
close to the pump.
• The fluid drain valve assists in relieving fluid
pressure in the pump, hose, and dispense valve.
Triggering the valve to relieve pressure may not
be sufficient to relieve pressure when the Fluid
Shutoff Valve (J) is closed.
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.
