10.1 Using a pressure feed system
To increase spray time between material refills, your HVLP spray
gun can be connected to a larger material pressure pot and air
compressor.
Converting the gun to pressure feed
Before using a pressure feed system, the spray gun must be
converted to a pressure fed gun.
1. Loosen the retaining nut (Fig. 29, item 1) using a wrench and
remove the one liter cup assembly (2).
2. Pull the air tube (3) off of the air tube fitting on the spray gun.

3. Place the pressure cap (4) over the nipple on the gun head.
Connecting to a 2-liter remote pressure pot
1. Convert the gun to pressure feed (see steps above).
2. Connect hoses:
a. Make sure turbine is turned OFF and unplugged.
b. Attach remote pressure pot to the turbine via the hose
configuration shown in figure 30.
c. Tighten the air hose connections by hand.
d. Tighten the fluid hose connections with an adjustable
wrench.

10.2 Converting to Top Feed
The cup is designed for a maximum working
pressure of 6 PSI (0.41 bar). Pressures higher than
6 psi can result in cup leakage, damage to the
equipment, and/or potential injury to the user.
The top feed HVLP spray gun is designed for use in special
applications such as spraying in confined areas. The position of
the cup gives the top feed gun the ability to spray downward and
overhead.
When spraying with the top feed gun, remember the following tips
for the best results. Keep the cup pressurized at all times when
spraying. Attempting to gravity feed the material will slow or stop the
flow of material at the nozzle.
i
It is recommended that the gun hook be removed
whenever using the top feed cup assembly.
To set up the spray gun for top feed delivery:
1. Loosen the retaining nut using a wrench and remove the one
liter cup assembly.
2. Pull the air tube (Fig. 31, item 1) off of the air tube fitting (2) on
the spray gun.
3. Separate the gun head from the gun rear (see instructions on
page 17). Reassemble gun head upside-down so fluid inlet
fitting on gun head points upward to accept the top feed cup
assembly.
4. Remove the gun hook and thread the retaining nut of the
top-feed cup assembly onto the fluid inlet (3) of the gun head.
Rotate the stand away from the cup and set the gun assembly
on a level surface.
5. Using an adjustable wrench, secure the retaining nut, making
sure the gun/cup assembly stays in a level position. The cup
should end up in a vertical position when supported by the
stand.
6. Connect the air tube to the air tube fitting on the spray gun.

Attention
The gun, when converted to top-feed, will not stand
on its own. Make sure to use the stand when filling.
Do not lay the gun on its side when it is filled with
material. Do not hang the gun by its hook when
filled with material.
