OPERATION
1. Determine proper location for unit. Unit should be located so that
inlet is gravity-fed. Unit will not draw water up from a lower level.
Position and level basin. Keep basin away from any item that could
puncture basin. Position selected should be convenient to inlet,
discharge and vent piping and electrical supply.
2. Plumb inlet. Using 1½" threaded pipe, plumb discharge to basin
cover fitting. Use a P-trap and a union next to the basin. Use pipe
joint compound and hand tighten only on plastic fittings. Do not
reduce below 1½" piping.
3. Plumb discharge. Using 1½" threaded pipe, plumb discharge to
basin cover fitting. Use a swing check valve no more than 3" from
top of basin cover and union. Be sure check valve is installed in
proper flow direction. If check valve is installed backwards, no water
will flow out of unit. Be sure discharge piping is sealed with pipe joint
compound and that lift height of pump is not exceeded. Hand
tighten only on plastic fitting.
4. Plumb vent. Plumb vent using 2" threaded pipe to fitting in basin
cover. Use pipe joint compound on threads and hand tighten only
on plastic fittings. The basin must be vented in accordance with
state and local codes. The vent is essential for proper switch
operation and must not be omitted or restricted.
THIS UNIT WILL NOT OPERATE WITHOUT PROPER VENTING.
CAUTION: Do not use a mechanical vent with this product. A
mechanical vent will cause improper operation of the automatic switch.
5. Test Unit. Connect power cord to electrical supply as stated under
"Electrical Connections." Secure power cord to piping with ties or
tape. Fill unit with water through inlet.Pump should turn on with 4" to
7" of water in tank, and turn off when 1½" to 3½" of water is left in tank.
