Never turn it on and off from the mains as this can throw the unit, only do this when packing away PCU or changing your filter. It must be kept on 24/7 to maintain heat and water quality.
1. F- 0, 1 or 2 on screen
An F - message is a heat setting on your control unit.
Holding down the 'heat' and 'jets' buttons for 2-3 seconds at the same time and use the '+' or '-' to scroll through F - 0 to F - 2 to set the maximum temperature.
F - 0 will allow 40º as the max temp
F - 1 will allow 38º as the max temp
F - 2 will allow 42º as the max temp
Press any other buttons to then escape and set.
If no luck with the F- message removal please click on the button below and generate a support ticket unless you already made a #6digitnumber which will be on your email subject line

1. The spa pipes have been correctly installed, make sure these are straight.
2. Filters are in good condition and not old, make sure they are the correct ones for our tubs.
3. Changing the water regularly (every 1-2 months dependent on use)
4. Checking for any hair or debris in the filter housing as it could lead down to the pump impeller (check every 2-3 days inner housing and wipe the white filter grid clean)
5. Make sure all o-rings are intact and not damaged as this can create an airlock or Error message.
The spa must be set on a flat and level surface, if not it can cause problems with the tub and cause issues to arise with the unit. Always make sure that the pipes are not kinked and are straight when fitted, to help fit these push in on the liner/bladder side first. Applying slightly soapy water on the inside of your pipes, so that they glide onto the ports much easier.
Make sure the whole spa unit has room behind itself. At least 10 cm is required extra all the way around as the inflatable main bladder will expand within a week or two, pushing the unit back and causing pipes to bend when against a wall. This will restrict the flow of water in and out of the tub.

Bleeding of filter housing 20 seconds video attached (Bleed filter housing.gif)
Check that the filter housing o-ring for the bleed valve isn't damaged or perished, making sure the star/sun valve where red arrow is pointing above is screwed down to stop air from drawing into pcu.
2. The spa must be filled up to the orange lines with hose water so that there is adequate water pressure to the unit from the tub and that the inlet & outlet caps have been removed.
3. Unscrew the air valve (star or sun valve) anticlockwise until air escapes along with water, continue doing this so there is just water escaping (Period of 20 seconds)
4. Retighten the air valve until secure again.
6. Set your desired heat temperature, and then press heat checking for water flow on the inlet and outlet ports within the spa.
Filter grid
The filter grid on base of the housing needs to be wiped and washed every 3-4 days, the example above is of hair that has built up.

| 1. Cap the ports (X2 caps) inside the tub if you do not want to drain the spa. | 2. Unplug the GFCI/RCD and disconnect the PCU from the connector hoses. |
| 3. Remove the Filter Housing Lid as well as the filter inside. | 4. Use a standard garden hose and insert it into the Heater Port (top right port). |
| 5. Hold the hose in the Heater Port and flush the system for approximately 2-3 minutes (water will exit from the Filter Port on the left). | 6. Turn the PCU upside down to empty the water. Check the discharged water for any debris that has been flushed out. |
| 7. Inspect the Filter Bowl for any trapped debris. Repeat the flushing process if necessary. | 8. Reinstall the PCU to the tub and start-up as normal. |
Backflush of the unit through heat port
1. Cap the ports inside the tub if you do not want to drain the spa.
2. Unplug the RCD and disconnect the PCU from the connector hoses.
3. Remove the Filter Housing Lid as well as the filter inside.
4. Use a standard garden hose and insert it into the Heater Port (top right port).
5. Hold the hose in the Heater Port and flush the system for approximately 2-3 minutes (water will exit from the Filter Port on the left).
6. Turn the PCU upside down to empty the water. Check the discharged water for any debris that has been flushed out.
7. Inspect the Filter Bowl for any trapped debris. Repeat the flushing process if necessary for longer.
8. Reinstall the PCU. Repeat the bleeding of the unit once again to the tub, and start-up as normal.
Always use filters for our portable range as these are made to size for the PCU housing and maintain the best water quality so that no large dirt particles pass through into the system.
Any other brand and difference in size will not be correct and cause problems down the line, these are bespoke to us.

KA-10010
These are bespoke to our filter housing and secure the lid down to stop debris bypassing the filter housing inner and blocking the pump, any filters that are smaller increase the chance of a blockage within the unit.
Do not take the unit apart or it will void your warranty, this picture below is to warn users;
When an error message still arises please turn off the unit, cap up the spa with the clear caps, drain the water from the unit as much as you can, and take the pcu indoors somewhere warm for 3-4 days. This usually resolves the issue and resets the sensor.
For Grand Rapids inflatable hot tubs below;
Make sure it is not deflating or is deflated, and change over the valve with the spare one that came in with the manual bag.
(Deflating spa below;)
You may want to check through the inside of the bladder (Inlet & outlet ports) as these might be kinked or have debris caught within.
You want to do the following;
1. Turn off the PCU from the mains.
2. Cap up the inlet & outlet ports, this stops water from escaping.
3. Remove the pipes from the bladder taking away the PCU from the spa.
4. You will now need to look through the body of the spa, seeing if there is a kinked or crushed inner pipe. It could be that it needs to be flushed out with a hose from the inside to clear any debris but we will need clear sight through.
5. Start it back up and see how you get on, this may correct the error message/heating or water quality issues.
(Internal inlet and outlet ports below)
Blue is inlet into pcu (drawing water into the pcu)
Red is the outlet back into the spa (warm water into the spa)

- Setup of your spa in situ like the one below (getting as many orange wavy lines into the picture including the control unit with the pipes and its surrounding area
- A video of the fault if visible trying to run through all modes and temp including the lock button
- A picture of your filter resting inside the filter housing with the lid off
