Routine Equipment Maintenance

Dimension One Spas – @Home Series Owner’s Manual

Draining Your Hot Tub

The spa is gravity-drained, without the need for a pump. To drain the spa, locate the hose bib, which was attached to the spa in the Initial Setup operation (described earlier), on the base near the lower left side of the equipment panel. Remove the cap (if any) from the hose bib. Screw a garden hose onto the hose bib, put the other end of the hose in a safe place for water run-off (do not drain onto lawn or plants), and then turn the valve on the side of the hose bib ninety degrees to release the flow of water. Do not forget to close the valve again before re-filling the spa.

For information about how often to drain and refill the spa, refer to the Water Care Guide that came with the spa.

Filter Cleaning

IMPORTANT: To prevent debris from getting into the system during filter cleaning, shut off the power to the spa at the GFCI circuit breaker (see Initial Startup section of this manual for details on the GFI).

To clean the skimmer filter, remove the access lid that covers the entire filter area. Lift the center float of the skimmer assembly until it is fully extended. Hold the centerpiece of the assembly and turn it counterclockwise until the flats of the basket are aligned with the securing tabs. Then pull the basket assembly straight up to remove it.

Below the basket is the filter. Remove the filter by twisting it 1/4 turn counterclockwise to its stop (be careful not to overturn it.) Then lift the filter out of its canister. Clean the filter with a high-pressure garden hose. Every other cleaning, soak the filter in filter-cleaning solution and rinse it thoroughly. Reinstall the filter by reversing the removal process, then replace the skimmer

basket assembly and the access cover. Then turn the power back on at the GFCI breaker. Run the pump a few minutes at high speed before leaving the spa in its normal heating mode.

Light Bulb Replacement

Some models are equipped with a standard light bulb, others with an optional “Dynamic L.E.D. Light.” Both are replaced in the same way. To change the bulb:

1.Turn the power off at the GFCI breaker and drain the water to below the level of the light.

2.Using the special tool provided in the owner’s manual packet, unscrew the lens that covers the light housing.

3.Remove the old bulb and install the new bulb.

4.Use the special tool to replace the lens on the light housing.

5.Turn the light on and off to make sure it works before refilling the spa.

Do not attempt to remove the lens without turning off the power and draining the water to below the level of the light.
