CAUTION To avoid premature wear of the pressure switch, never use more than 25 ft (7.6 m) of 1/4” ID outlet hose. When longer outlet hose is needed, use 3/8” ID hose at a maximum of 100 ft (30 m) long. Never use 1/4” ID and 3/8” ID hose together. Do not use lacquer or lacquer thinner in the suction and outlet hoses supplied with this system. These fluids quickly destroy the hose material. Use the optional chemical–resistant hoses. See ACCESSORIES section of the manual for ordering optional hoses
