Safety Alert The Safety Alert symbol identifies important safety messages on the TPT Unit and in the manual. When you see this symbol, be alert to the possibility of personal injury or death. Follow the instructions in the safety message.
Signal Words: Note the use of the signal words DANGER, WARNING, and CAUTION with the safety messages. The appropriate signal work for each message has been selected using the following guidelines.
DANGER – Indicates an imminently hazardous situation that, if not avoided, will result in death or serious injury. This signal work is to be limited to the most extreme situation, typically for machine components that, for functional purposes, cannot be guarded.
2 WARNING – Indicates a potentially hazardous situation that, if not avoided, could result in death or serious injury, and includes hazards that are exposed when guards are removed. It may also be used to alert against unsafe practices.
CAUTION – Indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.
Safety Decals 1. Keep safety decals clean and legible at all times.
2. Replace safety decals that are missing or have become illegible.
3. Replaced parts that displayed a safety decal should also display the decal.
4. Safety decals are available from the factory.
5. The following are the decals placed on the machine:
Safety Decals
3 Machine Overview
LPG Manifold Detail - Liquefied Petroleum Gas (LPG) regulator used to adjust heat output
- Pressure gauge shows fuel pressure to burner; pressure is not to exceed 90 PSI
- Solenoid valve controls fuel flow to burner
- Ball valve used to manually shut off fuel to burner
Handheld Controller Detail - Flipping ignition switch to the “on” position begins burner ignition sequence
- Flipping ignition switch to the “off” position (cover closed) stops flow of fuel to the burners
- Lights indicate that burners are lit
Burner Detail - Spark jumps between spark electrodes
- Flame sense electrode used to monitor flame
- If no flame is detected the solenoid valve is automatically closed
4 Control Box Detail - Master switch shuts off all power to the ignition system. Burners will not light with switch in the “off” position (cover closed)
- Temperature displays reads temperature sensor, located in rear exit nozzle
- Tachometer displays blower RPM
- Ignition controllers are located on the back side of the control panel
Startup Procedure 1. Hitch TPT trailer unit to tractor using supplied clevis hitch.
2. Move the trailer jacks to the horizontal (stored) position. Make sure both jacks are in the stored position.
3. Install power take off (PTO) shaft between tractor and trailer unit. The shaft is marked to ensure correct installation. NOTE: Verify that PTO shaft end labeled “tractor” is installed at the tractor.
4. Before connecting power cord, make sure the ignition switch and master power switch is in the “off” position.
5. Connect trailer power cord to tractor power supply and place the handheld controller where it can be easily accessed from the tractor.
6. Ensure trailer power cord is clear of any moving parts or pinch points.
7. Open all LPG bottles by turning the knob counter-clockwise. 5 8. Open ball valve between the LPG manifold and the burner. The handle will be in line with the valve body in the open position.
9. Flip main power switch, located in the control box, to the “on” position.
10. Make sure the area behind the burners and in front of the exit nozzles is clear.
11. Engage PTO drive on tractor at the lowest throttle position.
12. Flip ignition switch located on the handheld controller to light burners. The lights on the handheld unit indicate the burners are lit. If the burners fail to ignite the controller will shut off the gas to the burner and the light will turn off.
13. Check the pressure gauge on the LPG regulator to verify the pressure is at the factory preset of 70 PSI.
14. Ramp PTO up to working RPM, approximately 500 RPM.
Shutdown Procedure 1. Flip ignition switch on the handheld controller to the off position; this will shut off fuel to the LPG burners.
2. Ramp PTO speed down to lowest setting.
3. Allow PTO to run for at least 2 minutes to allow unit to cool.
4. Turn off main power switch.
5. Close ball valves between the LPG manifolds and burners.
6. WARNING - Some residual fuel will remain in the LPG manifold and the hose running to the burner which would cause the burner to light even if all the bottle valves are closed. This fuel can be removed by closing all the LPG bottle with the burners lit allowing all the residual fuel to be consumed.
6 Preparing unit for transport 1. Ensure both switches are in the off position.
2. Close ball valve between LPG manifold and burner.
3. Close all LPG bottles using top valve.
4. Remove PTO shaft.
5. Secure pendant cord and handheld controller.
6. If pulling unit to transport, trailer power cord must be plugged into vehicle power for the lights to work.
7. Check tire pressure and lug nuts.
Safety Notes - Ignition controllers and wire are high voltage.
- Do not exceed 90 psi on the LPG regulator.
- Beware of hot surfaces and rotating components.
- When storing or servicing unit, make sure both trailer jacks are in the down position to stabilize the trailer.
- Always ensure all LPG bottles are fully closed and master power switch is off before servicing or storing unit.
- WARNING - Some residual fuel will remain in the LPG manifold and the hose running to the burner which would cause the burner to light even if all the bottle valves are closed. This fuel can be removed by closing all the LPG bottle with the burners lit allowing all the residual fuel to be consumed.
Machine Maintenance - On each use, inspect all LPG hoses and plumbing for damage or leaks.
7 - After ten working hours inspect all LPG connections for leaks using a mixture of soap and water. Tighten all hardware on the gearbox, blower housing, and exit nozzles. Grease driveshaft bearing using multipurpose grease.
- After 200 working hours the gearbox oil should be changed; replace with SAE 90 oil.
- Inspect and clean the LPG fuel filter yearly.
