Installation – Typical Installation
The typical installations shown in Fig. 1 is only a guide
for selecting and installing a hose reel system. The
components and accessories 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
particular needs.
NOTE: The air and fluid accessories required for your
pump must be properly sized to that pump. Refer to
your specific pump manual for selecting pump
accessories.
Three accessories are required in your system: a
ground wire (G), a bleed-type master air valve (E)
and a fluid drain valve (H). These accessories help
reduce the risk of serious injury, including electric
shock and splashing in the 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 code.
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 pres-
sure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient.
WARNING
Air Line Accessories
Install the following accessories in the order shown in
Fig. 1, using adapters as necessary:
DBleed-type Master Air Valve (E): locate down-
stream from the air regulator and for easy access
from the pump.
DAir Regulator (D): controls pump speed and outlet
pressure by adjusting the air pressure to the pump.
Locate the regulator close to the pump but up-
stream from the bleed-type master air valve.
DAir Line Filter (C): removes harmful dirt and
moisture from the compressed air supply.
Fluid Line Accessories
Install the following accessories in the order shown in
Fig. 1, using adapters as necessary:
DFluid Drain Valve (H): install the drain valve point-
ing down but so the handle points up when the
valve is opened.
DFluid Shutoff Valve (J): shuts off fluid to the hose
reel.
DDispensing Valve (N): dispenses the fluid or air.

Installation – Mounting Options
All Mountings
NOTE: Always use large flat washers with the bolts
you use to mount the hose reel pedestal to any
surface.
CAUTION
Be sure the mounting surface is strong enough to
support the reels, the weight of the lubricants, and
the stress caused by hard pulls on the service
hoses. See page 23 for the dry weights of the
hose reel assemblies.
NOTE: All accessories mentioned here are shown on
pages 20 and 21.
1. Select the reel bank mounting location.
a. For high ceilings, suspend a suitable support
structure for the reels, so the hoses will be
long enough to reach your service area.
b. A reel bank mounted in a one-lift service bay
should be at least 6 ft (1.9 m) from the center
line of the lift See Fig. 2.
c. In a two-lift bay, mount the bank equal dis-
tance between the lifts. A bank of all motor oil
reels should be mounted about 5 ft (1.5 m)
from the center of the lift, toward the front of
the lift rails. See Fig. 2.
2. If you are installing permanent supply lines, drill
1.5-in. (38 mm) diameter holes through the ceiling
on the inlet side of the reels.
WARNING
To reduce the risk of injury, when you are mounting
a hose reel overhead, always use a lift truck.
Position the hose reel so the pedestal is facing up.
Using the lift truck, raise the reel as close to the
mounting location as possible. Bolt the hose reel to
its mounting, and be sure it is secure before lower-
ing the lift truck.

hole (60_). This will assure retraction when the
hose is at maximum extension. See Fig. 5.
3. Slide the hose reel onto the base plate (304) and
install the hold-down plate (302) and capscrew
(301). Tighten the screw firmly. See Fig. 3.
4. Connect the supply line to the inlet hose of the
reel. Purchase the hose inlet kit separately. See
Accessories on page 20.
5. Adjust the spring tension of the reel. Hose reels
shipped with hoses come from the factory with the
tension preset for a typical installation. To adjust
for more or less tension, see Increasing Spring
Tension on page 11. If you have purchased a
bare hose reel, see Installing a Hose on a Bare
Reel on page 10.

Installation – Installing a Hose
Installing a Hose on a Bare Reel
1. Locate the length and size of your hose in the
chart below. Note how many times you must turn
the reel to properly adjust the spring tension.
Hose Length No. of Reel Turns
50 ft (15.2 m) 13
60 ft (18.3 m) 15
2. Place a piece of tape on the side of the reel flange
to use as a visual reference to help you count the
number of reel turns.
WARNING
Always wear heavy gloves when you adjust the
spring tension to protect your hands from being cut
on the hose reel.
3. Wearing heavy gloves, firmly grab the outside
edge of the reel flange with both hands. See
Fig. 10. Wind the reel the proper number of turns,
rotating it in the direction shown in Fig. 10, and
stop only at latching locations. Stop the reel where
there is access to the hose swivel (34) (see Fig. 9)
and where the reel is securely latched.
4. Before you install the hose, attach a C-clamp (G)
to the reel flange to help prevent the reel from
unintentionally becoming unlatched and spinning
freely. See Fig. 10.
WARNING
Never allow the reel to spin freely. Doing so causes
the hose to spin out of control, which could cause
serious injury if you are hit by the hose.
5. Uncoil and extend the hose. Assemble the hose
stop (47) to the outlet end of the hose (48) and
tighten. See Fig. 11 on page 11.
6. Attach the hose (48) to the hose reel swivel (34),
and carefully remove the C-clamp. See Fig. 9.
7. Pull the hose hard enough to release the latch,
and slowly allow the hose to retract.
8. Position the hose stop (47) so the hose extends
far enough for all operators to reach the dispens-
ing valve. See Fig. 11 on page 11.
NOTE: The reel base (303) has two holes (H). Run the
inlet hose through either hole, depending on the
orientation of the hose reel. See Fig. 11 on page 11.
