in the spa. Allow the water to circulate for five min- utes. You should now test the pH level of the water. Use the included test strips to check the pH of the water. Refer to the instructions on the test strip pack- aging to see how to use the test strips.

If the level is too low, add one teaspoon from one of the ÒQUICK pHix It UPÓ packets to the water. Let the water circulate through the spa jet unit for five min- utes. Test the pH level again. Repeat until the pH level is correct.

If the level is too high, add one teaspoon from the ÒQUICK pHix It DOWNÓ packets to the water. Let the water circulate through the spa jet unit for five min- utes. Test the pH level again. Repeat until the pH level is correct.

Replace the spa cover and allow the water to contin- ue to heat.

See WATER CHEMISTRY on page 13 for information concerning proper water maintenance.

THE HEATING SYSTEM OF YOUR SPA

The heating system in your spa is designed to be economical for long-term use. Combined with the fact that water absorbs heat very slowly, the effect is that it will take 1 to 3 days (depending on the room tempera- ture) to heat the water in the spa. The good news is that once the water is heated, it will maintain its tem- perature for a relatively low cost. You can reduce the waiting period by filling the spa with hot water, but be aware that the spa holds more water than your water heater. Make sure the spa cover is on and that it is tight while the water is heating. The chart below shows approximate heating times for different air tem- peratures with a water temperature of 60¡ to 64¡F.

	Air Temperature	Heating Time
	At least 70¡F	20 to 28 hours
	At least 50¡F	28 to 48 hours
	At least 30¡F	48 to 72 hours
