Cleaning / Replacing Filter Cartridge
WARNING: RISK OF ELECTRIC SHOCK. Unplug the PCU before beginning spa
maintenance.
NOTE:
A dirty or incorrect filter cartridge may contaminate the spa water and cause damage to the heating
function.
1. Carefully thread the two inlet/outlet caps on inner spa wall. (Ensure the rubber gaskets are in place within
the plastic caps)
2. Remove filter housing lid by turning it anti-clockwise, then remove the filter cartridge.
3. Rinse off filter cartridge with water and reuse if possible. Replace filter if the cartridge remains dirty after
rinsing or is badly discoloured.
4. Put the cleaned filter back into the cartridge housing and close the lid by turning it clockwise.
5. Remove caps from the two inlet/outlet caps on inner spa wall and allow water to flow into pump. Next
purge air from the air valve on the PCU. The tub is now ready for use.
PART 6:
WATER MAINTENANCE
The filter cartridge should be cleaned weekly and replaced on a monthly basis, or
depending on use. A reminder (‘CHG FIL’) will appear to change the filter after 25 days.
Hold down ‘HEAT’ for 5 seconds to clear the message. Change water once a month or
depending on usage and use appropriate spa chemicals. Please pay attention to the
chemicals used and dosage. Spa damage resulting from misuse of chemicals is not
covered by the warranty.
Water Balance:
We recommend you maintain your water balance: PH value: 7.2 - 7.6;

water before each use of the spa, or at least once per week.

We suggest using chlorine granules to disinfect the spa’s water.
Spa Ball:
We suggest you use a spa ball to help in the filtration of your spa.

NOTE:
• The massage system will stop automatically after 30 minutes of operation. You can re-activate the jet
function by pressing the ‘JETS’ button. NOTE: Heater will automatically turn on when jets turn off.
• Heating and jet function cannot be activated at same time. When heating system is working, pressing the
‘JETS’ button will change heating mode into jet mode: heating and filtering are shut down, jet system is
activated. When jets are turned off, heating and filtering automatically resumes.
NOTE: Keeping jets on for a long period of time may cause spa water to lose heat.
• Pressing ‘HEAT’ activates the heating and filtering system at the same time. The ‘HEAT’ button will display
a solid red light as spa water heats up. Once desired temperature is reached, the heater will go into standby
mode, which will be indicated with a flashing red light.
NOTE: Heater will not resume until spa water drops 2 degrees below set temperature for maximum
efficiency. You can also manually restart the heater by pressing ‘HEAT’ when heater is turned off.
