This is a run-through on the majority of the control unit and other Canadian Spa Company portable V2 faults/messages on the screen or a spa issue. Please read through carefully as it may apply to your fault.
Firstly it's very important to keep the hot tub on & running with heat mode 24/7 at the set temperature. When not in use, clean, dry pack it away and keep it somewhere warm both the unit and spa.

Make sure the inlet and outlet caps have been removed and the water is above the orange wavy lines on the inside of the portable spa pool. Always fill the spa up with hose-temperature water, not a warm/hot tap.
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.

A friendly reminder to change the filter that may pop up which is CHG-FIL (See attached) To remove hold down the heat button for 5 seconds.

When checking your spa, make sure the green lock button is not flashing like CHG-FIL (See attached). When on this means that the lock button is on and the other buttons won't activate engage unless this is removed (Hold down heat for 3-5 seconds)
There may also be the following messages;

1. F- 0, 1 or 2 on screen

 

An F - message is a heat setting on your control unit.

 

Hold 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 escape and set.


2. 150 flashing on the screen

Please press and hold heat for 5 seconds if no luck press just any other button to remove this message.

The following checks are needed if the spa doesn't heat, there is an error message or the portable control unit becomes noisier than usual.

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 issues to arise with the control 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, This will mean the unit will also need room as the unit/PCU will be also pushed back causing the pipes to bend if not enough space. This will restrict the flow of water in and out of the tub so please make sure there is space for this expansion of the main bladder. 

10cm extra space required around the whole spa
Make sure the connector/pipes are straight not kinked
 
Swift Current on an incorrect surface
This will cause problems with your jets, heat and error messages will arise. 
Bleed star valve for 20 seconds
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.
1. Make sure the unit is turned off and connected to the tub (inlet & outlet caps have been removed on the inside)
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.
5. Turn the unit back on, press the jets, and then bleed once again from the cog for (Period of 20 seconds)
6. Set your desired heat temperature, and then press heat checking for water flow on the inlet and outlet ports within the spa.

After setting up when the unit/pcu is still noisy during heat mode please try the below;

Backflushing will clear any dirt or debris that might be stuck in the system, or kinked pipes (internal or external) also there is a chance that the tub isn't filled up enough.
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 over time.

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.

4 Pack of Portable Spa Filters
 
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.

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.

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 when carrying this out;

 

1. Turn off the PCU power 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, and see 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.
