Little TLC each day will help you keep the water healthy and your Brass Monkey happy
The PRO RANGE product has a muti-stage filtration system. However it relies on frequent observation to remove any blockages that may affect the flow of water through the cooling system. User load and showering before use will make a big difference to how often you need to clear, backwash or replace the water. Regular checks helps you stay on top of hygiene and take action when required, rather than waiting for an issue to build up.
Check & Clear
How does the water look?
Is it clean and clear or is it noticeably dirty/murky?
Are there debris or foreign objects within the unit?
Is there enough water?
| Do's | Dont's |
| Clear the pre filter that sits over the suction hole inside the unit. If debris are stuck in the bottom drain please see troubleshooting and remove drain for cleaning |
Don't ignore cleaning the pre filter or skimmer - if this becomes blocked it can reduce the flow water causing inefficient filtration and sanitisation and can cause damage to your unit. |
| Use the spa vac to reach into the water and clean around the pre filter removing any debris |
If the water is looking murky you may need to: - Complete and extended back wash and top up water - Clean the scum line - Complete a system flush |
|
This keeps the water flowing smoothly and helps to maintain a good flow rate. |
|
| Once done - move onto cleaning/emptying the skimmer (not applicable to barrels) |
Clearing the skimmer
If you have a stainless steel skimmer cover plate, remove this by sliding it up and putting it to one side whilst you complete the following steps.
1. Open the door to the skimmer, there is a groove on the door to help pull it open.
When holding the door open do not put excessive pressure on it.
2. Reach into the skimmer and take out the basket
Be mindful that the basket will catch any debris so do not empty this into the water.
3. Rinse the basket until all debris is removed.
4. Open the door the skimmer and replace the basket. The large lip should face the front of the skimmer
If you have a stainless steel skimmer cover plate, replace this by lining it up with the fittings on the bath and sliding it down into place.
Test & Dose
Prior to opening and then every 2 hours (minimum)throughout the day and at the end of the day after completing maintenance. Please check the instructions with your testing kit but as a guide follow the steps outlined.
Pool maintenance: chlorine and pH Levels
Chlorine: The ideal level is 2-4 ppm.
PH balance: The optimal range is 7.2–7.6, with 7.4 being the target.
These measurements should be taken:
- Before opening the pool.
- Regularly throughout the day to ensure levels remain stable.
- At the end of the day, especially after completing any maintenance tasks.
Step 1 Taking the Sample
- Get the water testing kit, including the dipstick and bottle.
- Attach the bottle to the dipstick and take both to the bath with a thermometer.
- Submerge the bottle 30cm into the water, fill, shake, and rinse it.
- Repeat, but this time hold the blue button on the dipstick to close the bottle while lowering it.
- Release the button to fill the bottle at 30cm depth, then press the button again to seal it before removing.
- Measure the water temperature with the thermometer at the same depth.
- Record water and air temperatures on the Daily Water Quality Test Log
Step 2 Reading the Sample
Follow test kit instructions to measure:
-
- Free Chlorine
- Total Chlorine
- Combined Chlorine
- pH
- Record results on the Daily Water Quality Test Log.
Step 3 - Interpret & Action the Results
Enter the clarity of the water under the same heading
- The optimum chlorine level is around 2-4 ppm.
- Anything above 5ppm is dangerous. Dosing should be stopped immediately and the bath put out of use until the water has been diluted and the re-tested to an acceptable chlorine level.
- If below 0.5ppm close the bath to users and increase chlorine levels by adding small amounts at a time - this is best done manually and placed in top of bath in the skimmer.
- When re-testing after dosing, wait 15 mins until the chlorine has fully mixed with the body of water.
- Test again until you meet the correct level.
Chlorine Dosing Example in our standard plunge: - 1g of HTH Granular will raise the level by 1ppm (Granular will require dissolving in warm water before adding into the skimmer basket)
- 3.5ml of Sodium Hypochlorite 15% will raise the level by 1ppm
PH Balance: Ideal PH rangę is 7.2 - 7.6 with optimum measure being 7.4
Back Wash TwistIIClean
| Do | Don't |
| Always ensure the red tag is positioned up before twisting to open or close the backwash. | When turning the TwistIIClean ensure you don’t twist too far, the red tag can get caught and break |
| If after backwashing the filter looks dirty complete a full clean. (See trouble shooting) | |
| Always Ensure the red tag is positioned up before twisting to open or close the backwash |
For models shipped before March 2024 see guide here
How to complete the TwistIIClean backwash
|
If you have a Hanna Dosing unit - Switch this off before putting bath into maintenance or backwash mode. |
|
1. Activate maintenance mode (Press and hold the down spanner for 3 seconds on control panel) |
|
2. Remove the bottom drain filter using the tool to screw into it, pull out, clean and replace |
|
3. Close the top filter by using the bung supplied Barrels - Remove the top filter by unscrewing and replacing with the bung Baths - Remove skimmer basket and insert bung into hole |
|
4. Activate backwash mode. (Press and hold the down arrow for 3 seconds on control panel). This turns the engines off whilst leaving the pump running. |
| 5. Pull the neoprene cover down so you can see the filter. |
|
6. On top of TwistIIclean, pull up red tag and turn to flush for approximately 2 minutes before twisting back to original position. *make sure you don’t turn too far or the red tag will break. |
| 7. Check all debris fully removed from filter. If debris do not clear after backwashing this is a sign you need to backwash more often. Follow steps in the trouble shooting section on how to remove the filter for cleaning . |
| 8. Exit backwash mode (Press and hold the down arrow for 3 seconds on control panel). |
| 9. Check the bath is running: Light illuminated and water flowing |
| 10. Remove bung fitted and replace skimmer basket or re-screw top filter |
| If you have a Hanna Dosing unit switch it back on now |
If you notice the filter is consistently dirty you may need to
- Increase backwashing length/frequency.
- Check users are showering before use
Water Top Up
Throughout the day as required and after washing.
- Activate Maintenance Mode - (Press and hold the spanner on the control panel for 3 seconds)
- Open FILL TAP, Bring water level up to the middle of the skimmer (Or 20cm from the top of the barrel) and then close fill tap
- Exit Maintenance Mode (Press and hold the spanner on the control panel for 3 seconds)
- Check the bath/barrel is running.
End of Day Wipe down and Checks
- Clean around the waterline using product such as sodium bicarbonate which can help to remove body fat around the waterline.
- Use an anti-bacterial cleaner to wipe down the insulated cover,
top deck, step and panels. - Ensure that water testing and dosing has been completed throughout the day and records maintained.
- If you use a Hanna Dosing unit, ensure chemical levels are filled.
- Ensure the skimmer basket and bottom drain have been cleaned, increase frequency of debris accumulates.
- Check when next system flush and quartile clean are due, consider doing these earlier if issues arise.
