Attention: Keep the steam engine clean.  
Attention: To avoid damage to the equipment, do not connect power directly to the components. 
IMPORTANT: Each unit is provided with a pressure-release device (safety valve) to address overpressure due to inadvertent blockage of the 
output steam head or piping.  
ELECTRICAL REQUIREMENTS: 
Electricity supply circuitry: 
1.  Test the voltage of the electric supply and make sure that the steam engine is supplied with suitable electric power. 
2.  Insulated copper wire should be used with a heat-resistant temperature of 190ºF and a specified voltage of 500V. Refer to national 
or local electricity code for the specifications. Refer to the ammeter for the ampere. 
3.  Make sure the steam engine and power supply are appropriate for each other. 
4.  Install an independent GFCI circuit breaker between the power supply and the steam engine. 
Important: All the connections must be in accordance with national and local electricity code and be installed by professional electricians. 
Note: All units are 220-240 Volts. The terminal may read N, L, G. The N is not a neutral. It is the second leg of the 220V of the power source.
