START UP & FILLING YOUR HOT TUB
Close all drains and fill the hot tub with water by putting the hose down the centre of the standpipe in the filter compartment. This will minimize airlocks in the equipment by filling through the heater, pumps and jets, pushing most of the air out of the lines. The water level of your hot tub should be maintained at a level of 1 inch above the highest jet.
AFTER the spa has been filled with water and the equipment compartment door is secured, power must be applied to the spa.
The jet pump(s), heating system and all internal plumbing will achieve a partial prime as the spa is filled. Once the jet system is fully operational (as indicated by strong, non-surging jets), priming of the spa is complete. Weak or surging jets are an indication of a low water level condition or clogged filter cartridges.
Adjust Total Alkalinity (TA) to between 80 and 120 ppm, Calcium Hardness (CH) to between 200 and 400 ppm, then spa water pH to between 7.2 and 7.6.
IMPORTANT: Add spa water chemicals directly into the filter compartment with the jet pump on high speed for at least ten minutes.
OPERATION NOTE: Adjusting the Total Alkalinity as the first step is important, as out-of balance TA will affect your ability to adjust the pH correctly and will prevent the sanitizer from operating effectively.
Superchlorinate the spa water by adding superfast chlorine. The jet pump should be running on high speed when adding the chlorine, and remain on high to circulate the spa water for a ten-minute period.
NOTE: All measurements for chemical dosage can be found on the packaging of the relevant chemical and relate to the volume of the hot tub so ensure you know the volume of your hot tub prior to dosing.
Set the temperature control to the desired temperature then place the thermal cover on the spa and allow the water temperature to stabilize (approximately 24 hours). Make sure you secure the cover in place using the cover locks. Periodically check the spa water temperature. When the water reaches the desired temperature, proceed to the next step.
Run the jets on high for 10 minutes to circulate the spa water. After the filter cycle is complete, test the spa water for Free Available Chlorine (FAC) residual. If the residual is between 3 and 5 ppm go on to the next step. If the residual is less than 3 ppm adjust the chlorine to between 3 and 5 ppm using Stabilised Chlorine Granules, dosage measurements will be on the side of the packaging.
Recheck the Total Alkalinity (TA) should be between 80 and 120 ppm, Calcium Hardness (CH) between 200 and 400 ppm, then spa water pH at between 7.2 and 7.6.
OPERATION NOTE: Make sure you adjust your Total Alkalinity first, as an out-of-balance condition will affect your ability to adjust the pH correctly, and will prevent the sanitizer from operating effectively. The spa is ready for use when the spa water has circulated and the chlorine level remains between 3 ppm and 5 ppm.
