Installation Guide

Air Blower

 Is there debris or residue trapped in the air jet caps? → Please clean the air jet caps. ► See page

35.

 One of the air jet caps on the side (not the bottom) of the bathtub is for detecting the water level. It

doesn’t produce air bubbles.

 A safety device will turn off the air pump when the temperature rises. Please wait for a while and try

again.

No air bubbles come out of the air jets.

 It stops automatically after the time on the timer has elapsed. ► See page 18.

This feature shuts off on its own.

 Is the automatic draining operation running to drain the bathtub? ► See page 33.

This feature starts up on its own.

 Right after the feature starts, cold water that had been in the pipes might come out.

 The air bubbles near the air jet caps on the bottom of the bathtub feel cool. Please adjust your

bathing position.

Cold water or cold air bubbles come out of the caps.

 When using the air blower, the water in the bathtub cools off quicker than when not using the air

blower.

The water in the bathtub goes cold sooner than expected.

Purging feature

 Is the water level at least 13-3/8” (34 cm) when draining the bathtub? → When the bathtub is

drained and the water level is low, the automatic purging feature won’t work. Please press the

Purge button to purge the bathtub.

 Is the On/Off button set to off? → The automatic purge feature won’t work if it is on. Please set it to

off.

 Please run the purging feature with the Purge button after the bathtub is empty. → Please check the

automatic purging feature the next time you drain the bathtub.

The automatic purging feature doesn’t work, even when I let the water out of the bathtub.

Hydro Hands and shoulder-warmer feature

 Is the water level in the bathtub low? → It won’t work if the water level is low. Please keep at least

13-3/8” (34 cm) of water in the bathtub.

It doesn’t work.

the bathtub.
