8- Replacing the quartz tube. Remove the O-Ring from the

old tube and place it on the new one. Position the new quartz

tube (8) into its place (12), first inserting the domed end and

checking that the other end has been inserted correctly in its

support (if the position is correct, only a small part of the tube

is exposed).

9- Retighten the nut (9) and refill the hot tub far enough to

operate the pumps and to verify that there are no leaks from

the nut; in case of leaks tighten it by up to 1/4 of a turn.If that

does not suffice, it is necessary to clean the quartz tube a-

gain, checking for leaks before proceeding to the next step.

10- Turn on the hot tub’s main switch again.

11- Activate the pump so that water flows through the Clear-

ray® system; allow it to continue to operate for about 5 min-

utes, making sure there are no leaks. In case of leaks, switch

off the pump and the master switch, repeating the quartz

tube cleaning procedure.

12- Reconnect the UV lamp (6) connector to the power sup-

ply (4); if replacing the lamp, insert it into the quartz tube.

Do not handle the UV lamp with bare hands; use a pair of

latex gloves to handle the UV lamp.

13- Place the lamp cover (5) on the nut (9).Finally, screw the

cover (2).

The UV lamp contains mercury; in case of replacement,

discard the old lamp as specified by law.

14-Turn on the hot tub master switch again and test the op-

eration of the device: the red led signals that the Clearray® is

powered (and should always be on) while the green one in-

dicates that the UV lamp is turned on.
