SAFETY
This section highlights safety warnings for this product. Warnings listed in this section
will be referenced throughout this document. Please review and understand the entire
manual before using this product.
Many components are charged with high voltage and/or in movement (fans), even
after the incoming AC power supply has been disconnected or switched OFF. Wait at
least 10 minutes for the total discharge of the power capacitors.
Always connect the frame of the equipment to the ground (PE) at the suitable
connection point.
All electronic boards have components that are sensitive to electrostatic discharges.
Never touch any of the electrical components or connectors without following proper
grounding procedures. If necessary to do so, touch the properly grounded metallic
frame or use a suitable ground strap.
No motor or VFD service should be conducted in the field. All inquiries on service for these
units should be directed to technical support: 1-877-934-3748
Wireless remote control functions on a 9 VDC battery accessed through the rear
battery compartment panel on the hand held remote. For extended battery life, it is
recommended to remove the battery if the cart is not to be used for long periods.
WARNING
EXPLOSION HAZARD
DANGER
Only used with specified products. DO NOT USE WITH LIQUIDS WITH A
FLASH POINT BELOW 100ºF (38ºC) OR USE WHERE FLAMMABLE VAPORS
ARE PRESENT.
The inverter control circuit (ECC3,DSP) and the HMI-CFW08-P are high
voltage circuits and are not grounded.
Always disconnect the supply voltage before touching any electrical
component inside the inverter.

Specifications and Features
Operating Instructions
Pump with the Variable Frequency Drive (VFD) will operate from 0 GPM
to 60 GPM utilizing the speed control on the wired remote or wireless
remote to increase or decrease the motor speed. Please reference WEG
CFW-08 manual.
VFD Operation
The VFD is pre-programmed at the factory to meet specification
compatible with the pump/motor assembly. No change to the program is
possible.
For codes generated on the display of the VFD, or issues that may arise,
please see the included WEG manual detailing operations and safety
requirements associated with the VFD. The standard CFW-08 keypad has a
LED display with 4 digits of 7 segments, 4 status LEDs and 8 keys.
Functions of the LED display: The LED display shows the fault codes and
drive status (refer to Quick Parameter Reference, Fault Messages, page 8 –
16 – WEG manual)
Functions of the “Local” and “Remote” LEDs: pages 67 - 71
Functions of the FWD/REV LEDs - Direction of rotation pages 67 – 71
Basic functions of the keys: pages 67 - 71
Pump Cart Maintenance
Pump cart tires are inflatable, Follow max recommended pressures as listed
on the tires.
Cart handle height is adjustable to three levels by removing the socket heat
cap screws on the vertical riser of the handle tube and adjusting to meet the
pre-drilled holes, then reinserting the screws to tighten.
ASSEMBLY
1.
Replace mechanical seal by sliding spacer (if new spacer is required or old spacer
was removed) onto shaft up to locating shoulder, then lubricate shaft with sanitary
lubricant.
2.
Push on seal gently until it engages with spacer.
3.
Fit rubber cup and seal seat into wearplate.
4.
Insert impeller in pump body.
5.
Fit O-ring in each end of the pump body.
6.
Fit wear-plate to body.
7.
Slide wear-plate and body assembly over shaft.
8.
Tighten screws to hold body to adapter flange. Torque screws to 10 in. – lbs.
9.
Fit end cover, with cover o-ring and end cover screws to body. Torque screws to 60
in. – lbs.
The pump is reversible utilizing the directional change button on the VFD or by reversing the
impeller manually.
Changing Pump Rotation (looking at end cover):
Clockwise Rotation:
Insert impeller into pump body with blades bending counterclockwise
Counterclockwise Rotation:
Insert impeller into pump body with blades bending clockwise.
DISASSEMBLY
1.
Remove the four end cover screws. Remove end cover and O-ring.
2.
Remove the four screws, holding the body to the motor adapter flange. Slide body,
complete with impeller and wear-plate, from motor shaft assembly.
3.
Remove mechanical seal by inserting two screwdrivers behind seal collar, and gently
lever collar and seal assembly forward on shaft. Use extreme care not to mar shaft
surface.
4.
Remove seal seat and rubber cup from recess in wear-plate.
