Be sure the hoses are in serviceable condition before connecting them to the pump. Remember that the suction hose must be reinforced construction to prevent hose collapse. Check that the sealing washer in the suction hose connector is in good condition (see page 16 ). Check that the hose connectors and clamps are securely installed (see pages 16 and 17 ). Check that the

12/01/16 12:27:48 31YG0610_016 OPERATION PUMP PLACEMENT For best pump performance, place the pump near the water level, and use hoses that are no longer than necessary. That will enable the pump to produce the greatest output with the least self-priming time. As head (pumping height) increases, pump output decreases. The length, type, and size of the suction and discharge hoses can also significantly affect pump output. Discharge head capability is always greater than suction head capability, so

12/01/16 12:27:58 31YG0610_017 OPERATION SUCTION HOSE INSTALLATION Use a commercially available hose and hose connector with the hose clamp provided with the pump (if necessary). Most hoses come with the connectors already installed. The suction hose must be reinforced with a noncollapsible wall or braided wire construction and cannot contain any perforations. The suction hose should be no longer than necessary. Pump performance is best when the pump is near the water level and the hoses are sho

12/01/16 12:28:05 31YG0610_018 OPERATION DISCHARGE HOSE INSTALLATION Use a commercially available hose and hose connector and clamp provided with the pump (if necessary). It is best to use a short, large-diameter hose, because this will reduce fluid friction and improve pump performance. A long or small- diameter hose will increase fluid friction and reduce pump output. Tighten the hose clamp securely to prevent the discharge hose from disconnecting under high pressure.

Reinstall the filler cap and tighten it securely. Priming water capacity: WT20X: 3.70 US gal (14.0 L) WT30X, WT40X: 3.96 US gal (15.0 L) Operating the pump dry will destroy the pump seal. If the pump has been operated dry, stop the engine immediately, and allow the pump to cool before priming. PRIMING WATER FILLER CAP
