WARNING
DO NOT RUN THE PUMP BEFORE PRIMING IT; THE SEAL AND IMPELLER COULD BE PERMANENTLY DAMAGED.
A) PRIMING: Remove the priming plug located on the top of the pump casing and fill the casing with water. Replace the priming plug.
B) PRIMING UNDER PRESSURE (Figure 1): To prime under pressure, place a check valve on the discharge line of the pump and a petcock or a ball-type
air bleeder in place of the priming plug, or an air bleed line with a gate valve connected to the discharge line. The liquid can then remain in the
discharge pipe, allowing the pump to draw the air bleeder, thereby facilitating priming.
C) STARTING THE PUMP: Never operate the pump dry as this may damage the seal. If an exceptionally long suction line is used, the pump casing may
become overheated or vapor-locked. Should this occur, replace the water in the casing with cold water and continue priming.
D) DRAINING: Should the pump be subject to freezing temperatures, it will be necessary to drain the pump completely. To drain, remove the drain
plug (10) located at the bottom of the front face of the pump casing and the priming plug (11) and make sure that the drain hole is not choked.
After all the water has been drained, operate the pump for a few seconds to ensure that the impeller (4) is devoid of water. Make sure that the
suction line is also devoid of water.
