Why does the water in my tank appear cloudy or changed in colour?
Check to see that your unit has not been positioned in direct sunlight as this can impact the water quality. If necessary, change the location of the ergometer to reduce exposure to direct sunlight.
Your tank requires a water treatment every 12-24 months. If the water becomes discoloured or shows signs of algae or bacterial growth simply add one Water Treatment Tablet. Do not use any other water treatment tablet other than those supplies with your unit. Please contact your nearest regional dealer to arrange the purchase of further treatment tablets.

Can I register my rower online?

Please refer to the back of your Owner’s Manual for a better understanding of the terms of your product warranty.

Where can I purchase water treatment tablets?
The time required between water treatments can vary greatly depending on your indoor rower’s location and exposure to sunlight. Typically, you can expect to treat your tank water every 12-24 months. If the water becomes discoloured or shows signs of algae/ bacterial growth, simply add one water treatment tablet.
To purchase additional water treatment tablets please consult your nearest regional dealer by visiting theFDF distributors page.

WARNING: Do not under any circumstance use any treatment tablet other than those supplied with your rower.

What is the ideal user's height range for the rowers?
There is no height specification for any FDF rower. The specific determinant is by leg length. This is the point of reference that determines whether the seat hits the backstop when the legs are straight.
On average (i.e. average leg length) a person of approximately 6’6” would be accommodated on a Pacific Rower, however, if their legs were unusually long in proportion to their height, this may not be a suitable fit. If in doubt, the most efficient way to determine your most suitable fit is to sit on a rower and stretch your legs completely out.
Some important criteria to consider for tall people include:

  • Ample seat rail length so the user can fully extend their legs
  • Rowing motion must not be compromised in any way
  • Users must be able to see the fitness monitor without having to bend their neck uncomfortably
  • Users must be able to access buttons (if applicable) easily
  • Footrests must accommodate larger foot (if applicable)
I noticed the tank was leaking on my floor?
With the resistance level set at the maximum, please:
  • Check tank is filled to the correct level, as shown by the fill level indicator on the tank cover.
  • Check that the filling cap is tightened or sealed.
  • Check if the seal is crooked on the Horizontal Rower.
  • Any sign of cracks around the tank bolts area or tank shell.
  • Fill upthe contact form, a distributor will be in contact as soon as possible.
Where can I find the serial number on the product?
The serial number information can be found at –Serial Number Location


There's no reading on my console?
Please check the sensor gap follow by the instruction manual provided below.

Can I connect a USB-enabled console to my Macbook?
We do not currently support macOS however plan to do so in the near future.

Can I write my own software to interfere with USB-enabled Consoles using an API or SOK?
For technical support reasons, we do not currently offer access to our proprietary communications protocol through an API or SDK.

Does the distance displayed in line with the real acceleration of the wheel compared to the water-resistance or is it just an estimation based on the number of stroker per minute?

  1. Flywheel Speed (RPM) through a stroke is used to determine stroke power.
  2. Stroke power is used to determine 500m split time.
  3. 500m split time is used with stroke time (catch to catch time) to determine stroke displacement (i.e. distance traveled through the stroke.
  4. Readings are updated per stroke.


What software version was put in the console at MFG?
The firmware version will appear once you POWER ON the console. It shows in the 2nd line of the LCD.

How would we know when a newer firmware would be made available?
Firmware updates can be done through the Fluid Connect DFU app (iOS & Android)

Do you have a list of compatible 3rd party rowing apps that are compatible with the Bluetooth Heart Rate console?
We don’t have a list of the APP compatible with the FDF FluidRower APP. As long as the APP support standard FTMS protocol for Rower data as well as the UBE Bike Data.

What is the specifics type of connectivity you offer for heart rate other than Bluetooth? ANT+, and/or Analog?
The Bluetooth Heart Rate console supports standard Bluetooth Heart rate and standard FTMS protocol.

Does Bluetooth connection for Zwift?
ZWIFT only supports Spin Bike at this moment. There is no Rower available in their APP

When does the Bluetooth Heart Rate console lose the memory of the BT connection with the phone? Instantly after the BT connection is terminated? Or does it take longer?
The console will check all sensor status. After 5mins without any input from the speed sensor or level sensor, the console will shut down. Bluetooth connection is defined as 1 to 1. You will need to go through the whole process again once your phone loses the connection.

Is there a Service Menu in the console? If yes, how to access and what can be done with it?
