ti27341a
4.On the RTX2000pi and RTX2500pi, open gun prime valve.
Grounding
The equipment must be grounded to reduce the risk of static sparking and electric shock. An electric or static spark can cause fumes to ignite or explode. An improper ground can cause electric shock. Agood ground provides an escape wire for the electric current.
This sprayer includes a ground wire with an appropriate ground contact. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a qualified electrician.
Power Requirements
100-120V units require 100-120 VAC, 50/60 Hz, 12 or 15A, 1 phase. 230V units require 220-240 VAC, 50/60 Hz, 10A
Extension Cords
Use an extension cord with an undamaged ground contact. If an extension cord is necessary, use a 3-wire, 12 AWG (2.5 mm2) minimum.

Preparation
NOTE: Lighter gauge or longer extension cords may reduce sprayer performance.
Auxiliary Air Compressor
Do not use an auxiliary air compressor with this spray system.
Generator Requirements
3500 W (3.5 kW) minimum.
Hose Size and Length
The system comes with a 25 ft (7.6m) hose set consisting of a 3/4 in. ID RTX1400si/1 in. ID RTX2000pi and RTX2500pi material hose and a 3/8 in-ID air hose.
Do not use more than 25 ft (7.6 m) of material hose.
Soft Start/Smart Start™ System (RTX2000pi and RTX2500pi only)
“Smart” vs. “Soft”
•“Smart” refers to the function where the motorstartsandstopswhenthetriggeris pulled and released. This keeps the sprayer at full operating pressure and allows the sprayer to spray immediately when the gun is triggered.
•“Soft” refers to the function where the sprayer slowly starts the pump. This prevents a large “splotch” of material from being discharged from the gun when trigger is pulled after the sprayer has sat idle for a period of time.
Smart Start
The Smart Start System is controlled by compressed air in the tanks and lines. When gun is triggered, air flows through the lines and opens a flow switch. There is also another pressure switch that senses when the compressed air system is at operating pressure. This second pressure switch allows the sprayer to start immediately when the sprayer is turned ON charging the compressed air system to full pressure. This method keeps the compressed air system at operating pressure if there is a small air leak in the system.
Soft Start
The Soft Start System is controlled by motor power and an air cylinder. When pressurized, the air cylinder pushes the rollers into the peristaltic pump pushing material through the pump. When the motor shuts off, a solenoid valve relieves the pressure in the air cylinder causing the rollers to disengage from the peristalticpump. When the motorstarts again there is a time delay while the air cylinders charge and move the rollers into the pump this is the “Soft Start”.

Mixing Material
Mixing Material
NOTE: Correct material mixture is essential. The pump will not operate if the mixture is too thick.
•Mix the material in a separate container before pouring it into hopper.
•Use Material Thickness Gauge to determine if mixture is thin enough to spray.
•The Material Thickness Gauge will only determine if the material is thin enough to pass through the pump. For some applications or for higher speed spraying, your mixture may need to be thinner.
•For best results, do not use partial bags of material.
