INTRODUCTION
The Model 1550+ AutoJet Modular Spray System featuring an HMI Touch Screen Display is a self-contained,
electronic/pneumatic panel that provides control of various aspects of a spray system. These systems come in a variety of
design configurations depending on the requirements of your spray application, therefore, you may or may not have all the
features described in this owner’s manual.
Product Features & Specifications
The Spraying Systems Co. 1550+ AutoJet Modular Spray System is a self-contained unit that can provide you with precise
liquid delivery and spray nozzle control in an affordable easy to use turn-key spray system. The system comes in a variety of
designs and configurations based on the type of spray nozzle used in your application.
The system can be used with water, oils, lubricants, inks, stains, water-based solvents, non-abrasive slurries. The system is
designed to spray most non-flammable or non-volatile materials. Liquids and materials that flow with viscosities below
1000 cP at 68° F (20° C) can be sprayed with the correct spray nozzle and controlled with this unique spray system solution.
System Usage
 The 1550+ AutoJet Modular Spray System is designed to run continuously or intermittently.
 The 1550+ AutoJet Modular Spray System features a high-quality HMI Touchscreen interface.
 System can control spray timing.
 Customer can set spray period, start delay and stop delay times.
 The controller is designed to run both electric and air actuated spray nozzles.
 Can drive Spraying Systems Co. electric spray nozzles (3 amps. max.) with Pulse Width Modulation (PWM).
Specifically, the PulsaJet® spray nozzle line and the AA250AUH Electric spray nozzles can be used.
 PWM (Pulse Width Modulation) is a technique used to control flow rate by rapidly pulsing the
nozzle on and off. PWM uses a duty cycle within the spray time. By definition duty cycle is the
percent of time of the total cycle time the nozzle is spraying. If the nozzle is spraying 50% of the
time, the DC is 50% thus the flow is ½ that if the nozzle being fully open.

Liquid Connectio ns - Pump Less version
The 1550+ Pump Less Version is designed to control the pressure down from a pressurized source. If the system is supplied
with a pressure pot, the customer must supply air to the pressure pot. The liquid out line of the pressure pot must then be
connected to the Liquid In fitting on the 1550.
NOTE: Pump less version systems require the liquid source to be pressurized to a minimum of 10 psi above the maximum
application pressure. The maximum required application or discharge pressure must not exceed 100 psi.
NOTE: The Pump Less version is not designed to pressurize a vessel or pressure pot. Only to control the liquid pressure
from a pressurized source to the spray nozzles.
o Connect suitable 1/2” O.D. tubing from the Liquid Inlet fitting to the liquid source.
 Metric systems use 12 mm O.D. tubing

Liquid Connectio ns – Pressure Pot version
The 1550+ Pressure Pot Version is designed to pressurize a vessel. It is not designed to receive pressurized fluid. It is not
designed to supply liquid directly to the spray nozzles. It only controls the air pressure going to the pressure pot. The
Pressure Pot system controls the flow of liquid using an internal manual liquid pressure regulator. This sets the air pressure
going to the pressure pot. For most materials the reading on the gauge should be close to the pressure at the liquid exit.
Note for high viscous and high-density materials this will deviate.
o Connect suitable 3/8” O.D. tubing from the Tank Air outlet fitting to the pressure pot air inlet.
o Tubing supplied if system is purchased with standard pressure pot.
 Metric systems use 10 mm O.D. tubing

o Connect suitable 3/8” O.D. tubing from the Liquid Out fitting on the pressure pot to the corresponding fitting on the
spray nozzle(s).
o Tubing supplied if system is purchased with standard pressure pot.
 Metric systems use 10 mm O.D. tubing
Mounting Spray Nozzles
Locate and mount the spray nozzles for your spray application. Depending on your application the spray nozzle lines and
connections will vary. It is recommended to run the lines starting from the spray nozzles to the system for easier
adjustment of lengths of the tubing. Note length should be kept to a minimum to reduce pressure drop. Note: If liquid
lines are long (>10ft.or 3m) flowrates and pressures will be affected. This can be worse when viscous fluids are being
pumped.
Notes on Nozzle Location
When locating the system in relation to the nozzles note these typical lengths of connecting items
You may or may not have these items depending on your project and order.
Nozzle hook up kits – Tubing 12 ft. (3.6m)
If your system was ordered with optional nozzle hook up kit the design of the hook up kit allows for 12’ of tubing from the
nozzle to the system for a single nozzle hook up kit. For multiple nozzle hook up kits they are designed to provide 12’
(3.6m) of tubing from each nozzle to the manifold and 12’ (3.6m) of tubing from the manifold to the system.
Electric nozzle cables – 10 ft. (3m) & 16.4 ft. (5 m)
All systems design to use electric nozzles comes with the required cables. IF your system did not come with these cables
please contact your local sales engineer.
 For a single electric nozzle system, the cable length is 10’ (3m) [Cable P/N LEXXSD3M83F030P, for AA10000 series;
P/N LE00M12MMDIN3MU for AA250 series]. For multiple electrical nozzles the system comes with cable from the
nozzle (one per nozzle) to a junction block that is 10’ (3m) [Cable P/N LEXXSD3M83F030P, for AA10000 series; P/N
LE00M12MMDIN3MU for AA250 series] and a cable from the junction block to the system that is 16.4 ft (5m)
{Cable P/N LE00M12M5M].
 If longer length cables are required, we offer an extension cable that is 16.4’ (5m) [Cable P/N LEXXSD4FD4M005P].
o This cable can be used to go between the nozzle cable and the junction block or the junction block cable
and the system.
o This cable can also be used to extend the trigger devise cable lengths stated below.
o Note due to voltage drop we recommend keeping the cable length to a reasonable length (approx. <50ft.).
Never attempt to chain more than four (4) cables together. Electric spray nozzle speed and performance
will suffer.
Trigger device cables – 16.4 ft. (5m)
All systems must be purchased with a trigger device to activate the system during operation. All of our offerings have a
cable length of 16.4’ (5m).
 If longer length cables are required we offer an extension cable that is 16.4’ (5m) [Cable P/N LEXXSD4FD4M005P].
o This cable can be used to go between the trigger cable and the system.
o This cable can also be used to extend the electric nozzle cable lengths stated above.
