Installation–Accessories and Restrictions
NOTE: The air and fluid accessories for your pump
must be properly sized to that pump. Refer to your
specific pump manual for selecting pump accessories.
WARNING
FIRE, INJECTION, and ELECTRIC
SHOCK HAZARD
Four accessories are required in your
system: ground wire, bleed-type master
air valve, thermal relief valve, and dump
valve. These accessories help reduce
the risk of serious injury, including fire,
electric shock, and fluid injection or
splashing in the eyes or on the skin.
These accessories are shown in Fig. 1.
The ground wire (G) must be connected to the
pump grounding lug and to a true earth ground
according to your local code.
The bleed-type master air valve (E) relieves air
trapped between itself and the pump after the air is
shut off. Trapped air can cause the pump to cycle
unexpectedly. Install the valve close to the pump.
The dump valve (J) relieves fluid pressure in the
displacement pump, hose, and gun. Triggering the
gun to relieve pressure may not be sufficient.
The thermal relief valve (H) relieves pressure in the
fluid line caused by heat expansion.
Air Line Accessories
Install the following air line accessories in the order
shown in Fig. 1, using adapters as necessary:
D Bleed-type master air valve (E)
Install downstream from the air regulator and close
enough to the pump for easy access.
D Air regulator (D)
Controls pump speed and outlet pressure by adjust-
ing the air pressure to the pump. Locate the regu-
lator close to the pump but upstream from the
bleed-type master air valve.
D Air filter (C)
Removes harmful dirt and moisture from the com-
pressed air supply.

Fluid Line Accessories
Install the following fluid line accessories in the order
shown in Fig. 1, using adapters as necessary:
D Thermal relief valve (H)
Install so that the outlet points down.
D Dump valve (J)
Install so that the outlet points down, and the
handle points up when the valve is open.
D Fluid shutoff valve (K)
Shuts off fluid flow to the hose reel.
D Dispensing valve (N)
Dispenses the fluid.
D Flexible inlet hose (Q)
Fluid inlet must be from a flexible hose, not fluid
piping.
Required Installation Accessories
Be sure you have these accessories before starting
the installation.
D Reel mounting bases and mounting brackets (if not
mounting on a truck)
D Dispensing valves
Mounting Restrictions
D Base-mounted hose rollers are for truck-mounted
hose reels. Accessory roller support arms are
available for overhead mounted hose reels. See
Roller Support Arm for instructions on installing
the roller support arm.
D Hose reel enclosures do not fit on these reels.
WARNING
To reduce the risk of injury when mounting a
hose reel overhead, always use a lift truck.
Position the hose reel so the mounting brackets
are facing up. Using the lift truck, raise the hose
reel as close to the I-beam as possible. Fasten
the hose reel to the I-beam, and be sure it is
secure before lowering the lift truck.
