Grounding

WARNING

FIRE AND EXPLOSION HAZARD

Before operating the pump, ground the
system as explained below. Also read
the section FIRE OR EXPLOSION HAZ-
ARD on page 4.

1. Pump: use a ground wire and clamp as shown in
Fig. 1. Loosen the grounding lug locknut (W) and
washer (X). Insert one end of a 12 ga (1.5 mm@)
minimum ground wire (Y) into the slot in lug (Z)
and tighten the locknut securely. Connect the other

Installation

Typical Installation

Mount the Evenflo Control (1) to the pump, using the
screws supplied with it to attach the mounting plate to
the pump base. Remove the screw and lockwasher
from the bottom of the control. Position the control
over the small hole of the mounting plate and reinstall
the lockwasher and screw.

Remove the cover of the supply drum. Place the
Sturdi-Clamp (3) over the edge of the drum and tighten
the tee handle (M) screw securely. Loosen the U­clamp. Lower the pump through the U-clamp until the
pump intake is about 1 in. off the bottom of the drum.
Tighten the clamp wing nuts (N). See Detail A below.

NOTE: Use thread sealer on all male threads except at
swivel connections. Swivels must remain free to move.

Connect the air and fluid hoses to the Evenflo Control
and the gun as shown in Fig. 2 and Fig. 4. Tape the
hoses every 18 in. (457 mm) for easier handling.

For automatic air motor lubrication, install an air line
lubricator between the pump air inlet and hose (E).
Otherwise, just connect the 18 in. (457 mm) hose (E)
from the Evenflo Control to the swivel air inlet of the
pump. For manual air motor lubrication, see MAINTE-

NANCE, page 9.

On the main air supply line, install an air line filter (B)
to remove harmful dirt and contaminants from your
compressed air supply. Also install a bleed-type master
air valve (A).

WARNING

A bleed-type master air valve (A) is required in your
system to reduce the risk of serious bodily injury,
including fluid injection, splashing in the eyes, and
injury from moving parts, if you are adjusting or
repairing the pump. Order Part No. 107142

This valve relieves air trapped between the valve
and the pump after the air supply is shut off.
Trapped air may cause the pump to cycle unex­pectedly. Locate the valve within easy access of
the pump.

Connect the air hose (12*†) from the 1/2 npt(f) Evenflo
swivel air inlet to the main air supply line. Then con­nect the hose’s ground wire (C) to a true earth ground.

Operation

Pressure Relief Procedure

With the Evenflo control, its bypass valve, and the
pump Relax-A-Valve properly set, fluid pressure is
relieved from the pump and hose each time you re­lease the gun trigger. Always engage the gun trigger
safety when you stop spraying. To relieve air pressure,
close the Evenflo regulators and open the bleed-type
master air valve.

WARNING

INJECTION HAZARD

If you suspect that the Evenflo system is
not properly set, or that pressure is not
fully relieved, the system pressure must

be manually relieved to prevent the system from
starting or spraying accidentally. Fluid under high
pressure can be injected through the skin and
cause serious injury. To reduce the risk of an injury
from injection, splashing fluid, or moving parts, fol­low the Pressure Relief Procedure whenever you:

D are instructed to relieve the pressure,
D stop spraying,
D check or service any of the system equipment,
D or install or clean the spray tips.

Relax-A-Valve Automatic Position

To set the pump Relax-A-Valve (G) in the automatic
position, loosen the locknut (H), turn the T-handle (J)
clockwise as far as possible, and then back-off the
handle four turns and tighten the nut. See Fig. 3.

NOTE: Every time you resume spraying, ensure that
the Relax-A-Valve is in the automatic position.

1. Close the air regulators.

2. Open the bleed-type master air valve.

3. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.

4. Lock the gun trigger safety.

5. Carefully loosen a fluid hose fitting and relieve
pressure gradually.

If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the

tip guard retaining nut or hose end coupling and relieve
pressure gradually, then loosen completely. Now clear
the tip or hose.

Mixing by Circulation (Fig. 4)

1. Close the Evenflo bypass valve (K) by turning the
valve handle clockwise.

2. Turn both air regulator handles counterclockwise
to the free position.

3. Disconnect the gun air atomizing hose (13*) from
the left air regulator.

4. Open the Relax-A-Valve handle (J) fully counter­clockwise.

5. Open the bleed-type master air valve (A).

6. Turn the left regulator handle clockwise until air
bleeds slightly through the open union (F).

7. Turn the right regulator handle clockwise to start
the pump. Increase the air pressure until the pump
circulates fluid through the Relax-A-Valve return
(drain back) tube at the desired rate.

8. After mixing, turn both regulator handles counter­clockwise to the free position, connect the air
atomization hose (13*) to the left regulator, and set
the pump Relax-A-Valve in the automatic position.

Pump Operation (Fig. 4)

NOTE: Fluid can be mixed by circulating it before

spraying. See Mixing by Circulation.

1. Engage the gun trigger safety. Remove the gun air
cap; this prevents fluid from being forced back into
the gun’s air passages.

2. Turn the Evenflo bypass valve (K) fully in to close
it.

4. Set the Relax-A-Valve (G) to automatic.

5. Open the Evenflo ball valve (L) (handle parallel to
body), and the bleed-type master air valve (A).

6. Set the atomizing air pressure to the gun at 40 psi
(2.8 bar) by turning the left regulator handle clock­wise.

7. Direct the gun back into the drum. Release the
trigger safety and trigger the gun. Set the right air
regulator to 30 psi (2.1 bar). The pump will oper­ate, filling the hose and gun.

8. Adjust the right regulator to the lowest pressure
necessary for the desired delivery rate; this varies
according to the fluid being pumped and other
system characteristics.

9. Release the gun trigger, engage the trigger safety,
and install the air cap.

10. Release the trigger safety and trigger the gun.
Adjust the left regulator until the fluid is properly
atomized. To minimize overspray, use the lowest
pressure necessary for good atomization.

11. Adjust the Evenflo bypass valve (K).

a. Be sure the Relax-A-Valve (G) is set in the

automatic position.

b. Be sure regulated air pressure is being sup-

plied to the gun and pump.

c. Open the bypass valve (K) four full turns

counterclockwise from the closed position.

d. Trigger the gun, directing the spray into the

drum. If the pump does not operate, release
the trigger and close the bypass valve 1/4 turn
clockwise.

3. Set both regulators in the free position by turning
the handles fully counterclockwise.

8 306402

e. Trigger the gun again. Repeat step d until the

pump starts when the gun is triggered.

Maintenance

WARNING

To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 7.

1. Remove and clean the strainer in the Evenflo
body, add light oil to the screen cavity and re­assemble every day.

2. If the pump was not flushed and has not been
operated for more than one day, disconnect the
spray gun fluid hose, turn on the pump, and pump
out a small quantity of fluid. This removes any fluid
that has set-up in the hose.

Flush with a fluid that is compatible with the fluid you
are pumping and with the wetted parts in your system.
Check with your fluid manufacturer or supplier for
recommended flushing fluids and flushing frequency.
Always flush the pump before fluid dries on the dis­placement rod.

CAUTION

Never leave water or water-base fluid in the pump
overnight. If you are pumping water-base fluid, flush
with water first, then with a rust inhibitor such as
mineral spirits. Relieve the pressure, but leave the
rust inhibitor in the pump to protect the parts from
corrosion.

3. Whenever you are done spraying for the day,
relieve the pressure. Cover the drum to protect it
from contaminants and air, which may cause the
fluid to harden.

NOTE: Be sure you flush the system thoroughly before
any fluid has a chance to set-up or harden.

Air Motor Lubrication

If your system does not include an automatic lubrica­tor, remove the hose (E) to the pump air inlet. Place 15
drops of light machine oil in the inlet. Reattach the
hose and turn on the air to blow the oil into the motor.
Repeat this process every day.

Flushing

WARNING

FIRE AND EXPLOSION HAZARD
Before flushing, read the section FIRE
OR EXPLOSION HAZARD on page 4.

Be sure the entire system and flushing
pails are properly grounded. Refer to

Grounding on page 5.

WARNING

To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 7.

1. Relieve the pressure.

2. Remove the spray gun and clean it according to
the supplied instructions.

3. Remove the pump from the drum. Wipe excess
fluid off of the pump. Place the pump in a
grounded metal flushing container, with enough
compatible solvent for flushing the entire system.

4. Open the bleed-type master air valve, the pump
Relax-A-Valve, and start the pump. Circulate the
solvent for at least 15 minutes.

5. Close the Relax-A-Valve. DIrect the fluid hose into
the fluid supply drum. Start the pump. When the
solvent appears at the hose end, quickly transfer
the hose to the flushing pail and allow the pump to
circulate solvent through the pump and hose until
clean.

6. Relieve the pressure.
