

2.1 About Your New Spray Gun

The Apollo 7500 AtomiZer HVLP spray gun is a multi-use, multi-purpose HVLP spray gun. The 7500 AtomiZer will operate

on most professional HVLP turbine systems or as a TrueHVLP™ spray gun on any air compressor (3hp – 20 gal [75 liter]

tank or larger). The 7500 AtomiZer is designed to operate as a production spray gun from a fluid feed system, a bottom

mounted cup gun or as a top mounted cup gun.

2.2 The 7500 AtomiZer® & Turbine Systems

The 7500AtomiZer is a standard turbine spray gun – non-bleed type. When the turbine is turned on, NO air will flow through

the spray gun. When the trigger is partially pulled, air will flow through the air cap. When the trigger is fully pulled, paint will

flow through the nozzle (tip) to meet the air flow, atomize and project to your work surface. It is most important that your

turbine system be equipped with a proper internal air relief valve to

handle the back pressure when the trigger is released and the turbine

is running.

All Apollo models manufactured after 2007 which includes; 725, 825, 835,

835VR, 1025, 1035, 1040VR, 1050, 1050VR, Power-3, Power-4, Power-5,

Precision-5 and Precision-6 are equipped with an internal air relief valve. All

otherApollo models manufactured prior to 2007 and not previously listed will

require an external relief valve that must be attached to the air outlet on the

turbine before using the 7500 Atomizer spray gun. Failure to install part

number A7538A when using the 7500 AtomiZer spray gun with older turbine

systems can cause premature failure of the turbine motor due to excessive

back pressure and will void your warranty.



If you are using the Apollo 7500 AtomiZer spray gun with a turbine system other than one manufactured by APOLLO, it is

advised to inquire with the turbine manufacturer to determine if your unit is configured to accept a non-bleed spray gun. If

you are not sure, or if you cannot get accurate information it is strongly advised that you install Apollo part number A7538

prior to using the 7500AtomiZer spray gun.

2.3 O.S. – Overspray Control/TexturingFeature (Optional)

The O.S. control will permit the safe reduction of air flow and air pressure fromthe turbine, when necessary. The O.S. control

should be used if an extremely thin coating or low viscosity product is being sprayed and you desire to reduce atomizing

pressure to achieve maximum efficiency and the least amount of overspray for your turbine unit. The O.S. control can also

be used to create a textured or splatter effect with selected coatings.

NOTE: O.S. Control is not needed when using an 835VR, 1050VR or Precision 5 variable speed

turbine system.



2.4 The 7500 AtomiZer®As A Bleeder Type Spray Gun

With the appropriate optional adapter, the 7500 AtomiZer can be operated as a bleeder type spray gun. Note there is a

blanking cap (#12B page 33) above the material adjusting screw (#19, page 33), this is where the upper port air hose coupler

(#12C, page 33) fits. Make sure you also blank the bottom of the handle with part (#28, page 33). This arrangement will

bypass the non-bleeder valve assembly and allow you to operate your 7500T spray gun as a “bleeder” style gun.

Sometimes it’s not convenient to have the hose connected to the bottom of the handle. This option also allows you to hold

the hose in a different position, by connecting your air hose to the top of the spray head and running the hose over your

shoulder. This is especially nice when spraying, hoods on cars, tables, or inside bathtubs.

3. Setup

3.1 Installing Air Relief Mechanism (Turbine Systems Only)

As previously noted,Apollo Models 725, 825, 835, 835VR, 1025, 1035, 1040VR,

1050, 1050VR, Power Series and Precision Series have an air relief mechanism

internally installed and DO NOT require an external air relief mechanism. All

other Apollo Models require theinstallation ofApollo Part #A7538A to the turbine

air outlet prior to operating The AtomiZer 7500 spray gun.

The air relief mechanism Part #A7538A must also be installed on ANY MAKE

turbine system that does not have an air relief mechanism installed. If using with

a system other than Apollo, please check with the manufacturer to determine if

a non-bleed spray gun can be safely operated on your system. If not, install Part

#A7538A before operating the 7500AtomiZer spray gun.



A7538



To install Part #A7538AAir Relief Mechanism, first locate and remove theAir Hose Quick Connect.



Second, screw the air relief mechanism onto the turbine air outlet. Third, screw the Air Hose Quick Connect onto the Air

Relief Mechanism. Make sure to install theAir Relief Mechanism with the bleed hole pointing upwards. Failure to do so, will

blow dust and dirt around on the floor while you are spraying.

3.2 Installing And Using The O.S. (Overspray) Control

To install the optional O.S. control follow these steps:

1. Remove the Upper Port Cap (12B, Page 33) and screw O.S. control

in its place.

2. Rotate the O.S. control air flow screw counterclockwise (anti-

clockwise) to its full open position. It is now ready to use.



Keep the O.S. control in the full open position when not in use. Rotate

the O.S. Control air flow screw counterclockwise (anti-clockwise) until it

stops, this is its full open position.

To operate, turn the air flow control screw clockwise at least 2/3 of the way

in. Test spray to see if the reduced flow of air reduces overspray/pressure

to your desire. If not, continue to rotate the air flow control screw until the

desired results are achieved. Be sure that you still have enough pressure

to atomize your coating to provide a good quality finish. If not, increase the

air flow by turning the screw counterclockwise until you feel you have the

most efficient results.

To create a textured or splattered paint effect, turn the air control screw all the way closed (clockwise). Do not thin your

paint, or if you have to, thin it very slightly to permit it to flow. Hold the spray gun further back from the work piece than you

normally would for regular finish spraying, at least 8” or more. You should now have a splatter effect. Adjust paint viscosity

accordingly to produce desired particle size.

In order to properly protect your turbine, you cannot completely shut off the air flow with the OS Control.

If you still feel that you are experiencing overspray, please refer to your instruction manual or to our website FAQ pages for

additional information.

3.3 Cup Assemblies and Turbine Air

A variety of cup assemblies are available for the 7500AtomiZer.



You can install a standard 1 quart (1 liter) cup

assembly to the 7500AtomiZer spray gun. An 8oz. (250cc) mini-cup assembly can be installed on

the 7500 AtomiZer spray gun when smaller quantities

of material are to be sprayed or when a smaller cup

assembly is desired.

A3oz (88cc) super-mini cup assembly can be installed on the 7500 for even smaller quantities of material or for compliance

with local regulations.



A top mounted gravity cup can also be used. Apollo offers a 250cc, 600cc and 1000cc top mounted cup.



250cc Cup 600cc Cup 1000cc Cup



The 7500AtomiZer can also be used as a production spray gun in conjunction with any size pressure pot.Apollo offers a 2

quart (2 liter), a 2.5 gallon (10 liter), and 10 gallon (37 liter) pressure pot (not shown).

3.4 Installing A One Quart Cup Assembly (For Use With Turbine Air)

To install a standard 1 quart (1 liter) cup assembly to the 7500 AtomiZer turbine spray gun follow these simple instructions:



1. Locate the cap (#11, page 33) that blanks the material connector not being used and make

sure that it is installed on the top material connection (#30, page 33).



2. Screw the cups center bolt to the material connector (#29, page 33), finger tight.



3. Locate the brass air feed nipple on the cup top and rotate the cup lid so

that the brass nipple is in the 7 o’clock position and the cup lever is in

the front of the gun.



4. While holding the cup assembly firmly, tighten the cups center bolt with

the wrench (spanner) supplied.

5. Remove the stainless steel screw located on the side of the spray gun and replace it with the air feed connector (#22,

page 33) located in the plastic bag inside your spray gun box.



6. Join the air hose to the spray gun from the cup. Connect one end of the air hose to the air feed connector (#22, page

33), and the other end to the brass nipple in the top of the cup lid. Be sure that the black half of the valve is facing toward

the cup.

3.4.1 Installing A Mini Cup Assembly

An 8oz. (250cc) or 3oz. (88cc) cup assembly can also be installed on the material connector when smaller quantities of

material are to be sprayed or when a smaller cup assembly is desired.
