The P1 Engine heater is designed to create cooling system temperature prior to starting the engine. Starting High Performance engines in cold temperatures & operating at high RPM to achieve normal operating temperatures creates excessive wear, noise & smoke pollution. Costly engine damage can also occur. Pre-heating an engine prior to starting minimises these problems and makes pre-race preparation much easier.
The P1 kart engine heater will take approximately 7 minutes to heat a water cooled kart engine to 50*C using a stable 240V power source. The P1 Engine heater has a fast, sensitive internal automatic temperature control that shuts the heater off once it reaches the desired temperature. The engine heater will automatically turn back on once the engine heater senses a temperature drop of approximately 10*C.
Installing the P1 Kart Engine Heater
- The engine heater is designed to be installed in the lower cooling hose that goes from the radiator to the water pump inlet.
- Disconnect the lower cooling hose from the water pump inlet.
- Cut 145mm off the end of the hose. Do not discard this 145mm off cut!
- Cut 65mm off the 145mm piece. This 65mm is now the outlet hose.
- Discard the remaining 80mm piece.
- Install the outlet hose to the heater outlet securing with a hose clamp. The heater outlet is clearly marked on the heater with an arrow.
- Install the heater with the outlet hose attached to the water pump inlet, secure using a hose clamp.
- Connect the water hose from the radiator to the inlet side of the engine heater and secure with hose clamp.
- Check the radiator hose length to ensure the hose is not kinked. Secure as required.
- Secure the water hose to the seat mount post with a cable tie. Ensure that the heater is not resting on the chassis rail.
- Secure the power cable in a convenient position to the seat mount post with a cable tie.
- Fill the radiator with coolant ensuring that all air is purged from the system.
**Any leaks in the cooling system will cause engine heater failure!**
- Leave the radiator cap off.
- Plug in to 240volt power source & turn on.
- Check the heater is circulating the coolant and install radiator cap.
- Once temperature is reached, disconnect from the 240 volt power source.
***CAUTION ***Ensure that the heater is protected from external water. i.e. racing in wet conditions, washing etc . The heater MUST be “bagged” to prevent external water entering the electric heater components. Failure to do this can result in heater failure.
