Service Checklist - Zoeller 63 Installation Instructions Manual

EASY DO'S & DON'T'S FOR INSTALLING A SUMP PUMP
1. DO read thoroughly all installation material provided with the pump.
2. DO inspect pump for any visible damage caused by shipping. Contact
dealer if pump appears to be damaged.
3. DO clean all debris from the sump. Be sure that the pump will have
a hard, flat surface beneath it. DO NOT install on sand, gravel or dirt.
4. DO be sure that the sump is large enough to allow proper clearance
for the level control switch(es) to operate properly.
5. DO Always Disconnect Pump From Power Source Before Handling.
DO always connect to a separately protected and properly grounded
circuit.
DO NOT ever cut, splice, or damage power cord (Only splice in a
watertight junction box).
DO NOT carry or lift pump by its power cord.
DO NOT use an extension cord with a sump pump.
6. DO install a check valve and a union in the discharge line.
DO NOT use a discharge pipe smaller than the pump discharge.
ELECTRICAL PRECAUTIONS- Before servicing a pump, always shut off the main power breaker and then unplug the pump
- making sure you are wearing insulated, protective sole-shoes and not standing in water. Under flooded conditions, contact your local
electric company or a qualified licensed electrician for disconnecting electrical service prior to pump removal.
Submersible pumps contain oils which becomes pressurized and hot under operating conditions. Allow 2-1/2 hours after
disconnecting before attempting service.
CONDITION

D. Pump will not shut off.
E. Pump operates but delivers little
or no water.

a period of use.
If the above checklist does not uncover the problem, consult the factory. Do not attempt to service or otherwise disassemble pump. Service
must be performed by Zoeller Authorized Service Stations. Go to www.zoellerpumps.com/servicestations to find the Authorized Service Station

down. Switch defective, damaged, or out of adjustment.
Incorrect voltage, negative head (discharge open lower than normal) impeller or seal bound mechani-
cally, defective capacitor or relay, motor shorted.
Float tight on rod, check valve stuck or none installed in long distance line, overload open, level switch(s)
defective, sump pit too small.
Debris under float assembly, float or float rod bound by pit sides or other, switch defective, damaged or
