CTP Series
Installation, Operation & Maintenance Manual
Install lifting chain or cable of adequate size
and load rating of the unit. Allow for proper
length to permit proper lowering and raising
of the pump. Properly position power cables
and lifting devise over the load and keep
them from entering the pump suction.
Prior To Installation:
Before lowering the pump into position check
the direction of rotation. The impeller will rotate
clockwise as viewed from the top. Therefore the
pump will try to move in the counter clockwise
direction as the impeller rotates (known as start
reaction). "Bump the Motor" by closing the
pump circuit breaker and push the pump start
button and look for the direction of movement
specified above. For three phase motors, if the
starting jerk is in the clockwise direction, open
the circuit breaker to isolate power and
interchange two of the three phase leads inside
the control panel.
Make sure to use lifting equipment that has
adequate capacity for the pump that will be
handled. Before installing pump, check to be
certain the profile seal is properly positioned in
the guide claw flange. Position pump so the
guide ears on the discharge flange engage the
rails. Slowly lower the pump along the guide
rails, once the pump reaches its bottom location
it will automatically connect to the base.
Bolts
PUMP MODEL Anchors SIZE TORQUE
2-2 ½ ” CTP-SERIES 4 M12mm 37 ft/ #
AUTOCOUPLING
3” CTP-SERIES 4 M12mm 74 ft/#
AUTOCOUPLING
Notes:
1. Flange bolts must be tightened in cross
pattern to avoid damage to the raise face
flanges.
2. Standard Anchors are Plated Steel
3. Autocoupling systems include qty 4 M12
anchors for the upper bracket. Torque to 38
ft#.
4. Anchor bolt holes should be drilled to the
actual diameter of the anchor (M12 anchor
requires 12mm diameter hole).

START-UP
Prior To Applying Power
Prior to applying power to the pump; double
check all wiring and verify that the power
(Voltage, Phase) that will be supplied to the unit
matches the nameplate specified values.
Measure resistance of cable and pump motor
resistance of ground circuit between control
panel and outside of pump. Perform MEG ohm
check of motor insulation. Record all data on
start-up checklist which is included with this
manual.
Wet Well Applications
If the above checks prove satisfactory the pump
is ready for operation. Lower the pump into
position. (Refer to Mechanical installation
section of this manual.)
Open discharge valve, and verify that all check
valves operate freely. It is very common for
discharge check valves to be jammed shut (or
open) after sitting for a period of time. Once all
valves are open and free, start the pump and
allow it to stabilize for several minutes prior to
recording any test data.
Listen for any unusual noise and be on the
lookout for unusual vibration. This is generally
detectable on guide rails for Auto Coupling
installations and on discharge piping for ring
stand installations. Also for Auto Coupling
installations, look for any blow by from the
discharge connection.
Perform all remaining electrical, operational, and
performance tests specified on the start-up
report at the back of this manual. Record and
provide details on the checklist to validate
warranty.
Note: Do not install more then one (1)
check valve into any pump discharge
piping system or problems will occur.
