START-UP INSTRUCTIONS
Once the spa is placed on a proper foundation and con- nected to the appropriate electrical service, the spa may be filled and made ready for use. For best results, read each step in its entirety before proceeding with that step.
IMPORTANT - Do not activate power until the spa is filled. To avoid damage to the spa’s equipment, the pumps must never be operated unless the spa is filled with water.
1.PREPARE SPA FOR FILLING
•Clear all debris from the spa.
•Although the spa shell has been polished at the fac- tory, you may want to treat it with a specially formulat- ed spa cleaner and wax available from your dealer prior to filling it for the first time.
•Before filling your spa for the first time, refer to the “EQUIPMENT COMPARTMENT” illustration on page 11 and perform the following procedures to ensure proper operation:
•Remove the equipment compartment door.
•Check all pump and heater unions to ensure that they are
•Check that all knife valves are in the open position.
(Clear, plastic tubing has been
• Install pump drain plugs, if necessary.
(During winter months, the pumps’ drain plugs are removed to prevent possible freeze damage during shipping and storage. If this is the case with your spa, there will be a notice to this efffect taped to the front of the spa’s control box and the drain plugs will be in the plastic bag that includes the owner’s manual.)
2. FILL THE SPA
NOTE: Never fill your spa with water from a water softener. Its corrosive effects will damage your spa’s components.
•Remove the skimmer basket and weir - see page 12.
•Insert the end of a garden hose into the filter canister and begin filling the spa.
•Stop filling when the water level is approximately one inch above the highest jet.
•Reinstall the skimmer basket and weir.
3.TURN ON POWER
Turn on power to the spa at the home’s circuit breaker, Ground Fault Circuit Interrupter (GFCI) and any other switching devices installed by your electrician. When power is on, the spa’s LCD screen will display information.
4.ACTIVATE JETS
•Set all air controls to the “Max” position to help you see which jets are being activated. See illustration on page 6.
•Press the “Hydro Jets 1” touch pad on the control panel twice to turn on the high speed of the dual- speed pump - see “SPA SIDE CONTROLS” illustration on page 8.
•You should be able to feel a steady stream of water from at least some of the jets. If not, refer to the instructions for priming the pump in the SPA TROU- BLESHOOTING section in the back of this manual.
•Press “Hydro Jets 1” again to turn off, then press “Hydro Jets 2” to turn on the
5.ADD START-UP CHEMICALS

fer a different temperature, press either the 
or 
touch pad to display the temperature which has been set. Then, each time either of these pads is pressed
again (within five seconds), the set temperature will increase or decrease depending on which pad is pressed.
•The maximum temperature for which the spa can be set is 1040F and the minimum is 800F.
DANGER. RISK OF INJURY. Always check the water temperature carefully before entering the spa.
7.SET SPA TO HEAT
•Make certain the controls are set to operate in the “STANDARD” operating mode. That is, if the LCD
shows “ECON” flashing alternately with the water tem-
perature, press the 
touch pad to switch to “STANDARD” mode. This allows the heater to run con- tinuously until the set temperature is achieved. (See “STANDARD OR ECONOMY MODE” on page 9.)
