9.Fill the pump with water.

10.Reinstall the pump lid and plastic clamp; see SECTION II. START-UP.

11.Reprime the system. C. The Shaft Seal.

1.The Shaft Seal consists primarily of two parts, a rotating member and a ceramic seal.

2.The pump requires little or no service other than reasonable care, however, a Shaft Seal may occasionally become damaged and must be replaced.

CAUTION

The polished and lapped faces of the seal could be damaged if not handled with care.

CAUTION

In mild climate area, when temporary freezing conditions may occur, run your filtering equipment all night to prevent freezing.

SECTION IV. RESTART INSTRUCTIONS.

A.If pump is installed below the water level of the pool, close return and suction lines prior to opening hair and lint pot on pump. Make sure to re-open valves prior to operating.

CAUTION

DO NOT run the pump dry. If the pump is run dry, the mechanical seal will be damaged and the pump will start leaking. If this occurs, the damaged seal must be replaced. ALWAYS maintain proper water level in your pool (half way up skimmer opening). If the water level falls below the skimmer opening, the pump will draw air through the skimmer, losing the prime and causing the pump to run dry, resulting in a damaged seal.

Note

Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump case, impeller and seal.
