Please be sure not to be bended any of suction inlet hose and outlet hose. This can
causes loosing vacuum power or damage of suction motor. Also use exhaust air hose with
40mm diameter hose.
Exhaust air temperature increases significantly and discharge drastically too hot for most
plastic piping. Therefore, metal piping or heat-resistant pipe is recommended for at least
the first five (5) to eight(8) feet (1.5 ~ 2.5 meters) from the air exhaust valve on the
discharge side. In addition, this piping MUST be guarded and marked
“DANGER–HOT–
DO NOT TOUCH.”
