Do not bunch hoses together. Leave at least a 25 mm gap between them so the heat dissipates adequately. Do not cover hoses. If the hoses need to be covered, make sure there are vents to allow the heat to dissipate. Do not install hoses with clamps that place pressure on the diameter.
3.5. ELECTRICAL WIRING: The electrical wiring depends on the model. See electric diagrams. Make sure the power source is duly protected and you are using the right cable for the machine’s electrical power needs. Secure the power cord to the machine bench in order to prevent an accident. Connect the pump permissions to the safety line on the main machine.
