START-UP AND REFILL PROCEDURES
6
Your spa has been thoroughly tested during the manufacturing process to ensure reliability and long-term customer satisfaction. A small amount of water may have
remained in the plumbing after testing and, as a result, may have spotted the spa shell or the spa siding prior to delivery. Before filling the spa, wipe the spa shell clean
with a soft rag.
The following instructions must be read and followed exactly to ensure a successful start-up or refill.

CAUTIONS

• Do not fill the spa with hot water, as tripping of the high-limit thermostat may result.
• DO NOT CONNECT POWER TO AN EMPTY SPA. Power to the spa automatically activates critical components within the spa, such as controls,
heater, and other systems. If power is supplied to these components prior to the spa being filled, the components will be damaged, and this may
result in a non-warranty component failure.
• Do not use your spa after filling until all of the steps listed below are completed.
• Do not add chlorine if treating your spa with polyhexamethylene biguanide (Biguanide, PHMB, eg. BaquaSpa
®
) sanitizer.
• Before filling your spa for the first time, remove the equipment compartment door and check to ensure that the unions on either side of the pump(s)
and heater are hand-tight.
1. Ensure that the drain is closed and remove the filter compartment cover, skimmer basket, weir, and filter. Then insert the end of a garden hose into the filter canister
and begin filling the spa. The water level of your spa should be maintained at a level one inch above the highest jet in the spa excluding the four above-the-water-
line neck jets in the EsctaSeat
®
. Reinstall the filter and then the skimmer basket, and weir once the spa is filled.
IMPORTANT:Watkins®Manufacturing Corporation does not recommend that the spa be filled with “softened” water, as this may damage the spa’s equipment.
2. AFTER the spa has been filled with water and the equipment compartment door is secured, power must be applied to the spa.
3. The jet pump(s), heating system and all internal plumbing will achieve a partial prime as the spa is filled. To check the operation of the jet system and to purge any
remaining air from the heating system, push the “JETS” button icon on the control pad three times to make the jet pump(s) run on high speed for one minute. Once
the jet system is fully operational (as indicated by strong, non-surging jets), priming of the spa is complete. If you do not feel a steady stream of water from your jets,
refer to the instructions for priming the pump in the SPA TROUBLESHOOTING section in the back of this manual.
4. Adjust Total Alkalinity (TA) to 125 ppm, Calcium Hardness (CH) to 150 ppm, then spa water pH to between 7.4 and 7.6. These procedures are listed in the “Water
Quality and Maintenance” section.
IMPORTANT: Add spa water chemicals directly into the filter compartment after activating Clean cycle (press “SET”, then “JETS” buttons).
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.
5. Activate the Clean Cycle then superchlorinate the spa water by adding 1-1/2 teaspoons of chlorine (sodium dichlor) per 250 gallons (950 liters) of spa water.
6. Set the temperature control to the desired temperature between 100°F (38°C) and 104°F (40°C), then place the spa 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 temperature climbs above 90°F (32°C), proceed to the next step.
7. Press the “SET” button, then “JETS” button to activate Clean cycle and circulate the water. After the Clean cycle is complete, test the spa water for Free Available
Chlorine (FAC) residual. If the residual is between 3 and 5 ppm on the test strips go on to the next step. If the residual is less than 3 ppm, superchlorinate the spa
water by adding 1-1/2 teaspoons of chlorine (sodium dichlor) per 250 gallons (950 liters) of spa water, after the Clean cycle once again.
8. Recheck the Total Alkalinity (TA) at 125 ppm, Calcium Hardness (CH) at 150 ppm, then spa water pH at between 7.4 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 affect
the sanitizers effectiveness. The spa is ready for use when the spa water has circulated and the chlorine level remains between 3 ppm and 5ppm.
9. The spa temperature is pre-programmed to reach 102F (39°C), and will normally do so within 18 to 24 hours. You may raise the water temperature by pressing the
Temp Plus (+) button on the control panel, or lower it by pressing Temp Minus (–) button. After a few hours, the water temperature will remain within 3˚F (1.5°C) of
your selected temperature.
OPERATION NOTES:
1. Your spa is equipped with a ten-minute timer delay on the heating/tranquil mode. Whenever the jet pumphas been turned off (and a three-degree temperature drop
has occurred) or the temperature control has been turned up, it will take ten minutes before the low speed of the jet pump and heater become activated. Always
push the “JETS” button to turn off the jet pump when exiting the spa. The 230 volt system, the heating system does operate simultaneously with the high speed
pump.
2. The spa controller has an automatic one-hour “time-out” feature should the high speed jet mode be left on inadvertently. After one hour of continuous operation,
the controller will automatically return to the maintenance/heating mode.
3. The spa controller also has a six-hour “time-out” feature should the light be left on inadvertently.After six hours of continuous operation, the controller will
automatically turn the light off.
