2. About the DFI-150
The Dura Flow inverter circulation pump, DFI-150 is a self-priming
centrifugal pump for recirculation and ltration of the water in small and
medium sized pools with prelter integrated.
The DFI-150 is part of the full DuraLink solution. Communication is done
using power line communication. Which means that only 1 cable connection
is required for power and communication between a remote-control system
and the circulation pump.
The inverter for the DFI-150 is integrated in the circulation pump and allows
the pump to run run at variable speeds.
The pump is using a permanent magnet electro motor which is energy
efcient.
The DFI-150 is durable, reliable and easy to install.
The ambient temperature must be between 0 °C and + 40 °C and must be as
constant as possible. The relative humidity at the installation location must
not exceed 90%, no condensation may occur. Keep out of direct sun light
and away from heat sources.
The DFI-150 will only be controllable by the LINK Master.

4. Installation instructions
4.1. Warnings
Before installation and use of the pump, the basic safety warnings need to be
understood. Specic contents include the following warnings:
1. Be careful of electric shock. The pump can only be installed in combination
with the LINK Master. The LINK Master has all safety devices on board to
make for a safe installation.
Please check the LINK Master manual for instructions on how to install and
connect the DFI-150 correctly with the LINK Master. The DFI-150 has a
pre-connected in power cable with a length of 3,5 m.
2. Make sure the pump motor is disconnected from the main power supply in
case of maintenance or repair of the DFI-150.
3. The national standards and regulations for installation of the country in
which the pump is installed, should be followed.
4. Failure to comply with safety instructions may result in serious body injury
or death. The installation and maintenance of the pump must be done by
professional pool service personnel, installers or operators.
5. The owner of the pool must carefully read the safety warnings and
instructions before using the pump.

6. Special function description and application
6.1. Internal protection functions
See addendum 8.1 for corresponding error codes. In case of error, the error
code will be displayed on the LinkTouch or can also be retrieved in the
DuraCloud application.
6.1.1. Overvoltage and undervoltage protection
• If the AC voltage is higher than 240V or lower than 208 V.
• Starting the motor is disabled.
• The following codes can be displayed: OV1 for overvoltage and UV1
undervoltage.
6.1.2. Over-current protection
• After the fault occurs, the controller stops the output and automatically
clears the fault and restarts after 10 or 30 seconds.
• After 3 consecutive errors, the motor will not restart and one of the
following error codes will be displayed: OC1, OC2, OC3, OC4.
6.1.3 IPM (Intelligent Power Module) protection
• In case of IPM failure, the motor will immediately stop running
• The following error code will be displayed: OC3.
• The controller will automatically clear the fault and will restart the pump
after 30 seconds.
• After 3 consecutive errors, the motor will not restart, and the fault can’t be
cleared. Only after a power cycle of the motor, the fault will be cleared.
• In case the OC3 alarm remains even after a power cycle, then this means
that the internal hardware has failed.
6.1.4. Overheat protection
• When the motor temperature is higher than 95 °C, the system will automa-
tically and gradually reduce the motor speed in steps of 50RPM to protect
the motor. When the temperature is too high, the system stops running.
The following error code will be shown: OH1.
