Shaft Seal Change Instructions

When servicing electrical equipment, basic safety precautions should always be observed including the following. Failure to follow
instructions may result in injury.
A. Disconnect all electrical power service to pump before beginning shaft seal replacement.
B. Only qualified personnel should attempt rotary seal replacement. Contact your local authorized Hayward Dealer or
