Care And Maintenance - Utilitech 50AC-110 Install Manual

operAtioN iNStructioNS
1. Running the impeller dry for as short as 30 seconds can ruin the impeller. Keep suction line as
short as possible.
Note: An easy way to prime the pump (wet impeller), if using a garden hose to fill the discharge
hose, is to elevate the discharge hose slightly to retain water and start the pump. Another method
would be to disconnect the discharge hose from the pump, making a U-bend of the discharge hose,
fill the hose, and then reconnect (without losing the water) to the pump. In both cases the water
behind the impeller will seal the pump and it will prime almost immediately.
2. Be sure hose attachments or piping connections are tight. Any leakage in suction side will prevent
pump from priming.

cAre AND MAiNteNANce

• Always drain pump when not in use.
• If pump is not going to be used for a month or longer, flush with fresh water and remove body
cover; take impeller out, clean inside body and apply a generous coating of petroleum jelly to both
inside body and impeller before replacing impeller in body.
• The pump should be checked often for proper operation. If anything has changed since the
unit was new, the unit should be removed and repaired or replaced. Only qualified electricians
or servicemen should attempt to repair this unit. Improper repair and/or assembly can cause an
electrical shock hazard.
