WARNING:
BEFORE PERFORMING ANY MAINTENANCE ON THE MAST3RPUR SYSTEM, MAKE SURE THE SPA IS
SHUT DOWN.
a. UV Lamp Removal – See Figure 2.
If the Green Power Indicator is on, but the Blue UV Lamp Indicator is off, the UV lamp needs to
be replaced. However, the UV lamp useful life is 18 months. The Lamp must be replaced after
18 months of use, even if the Blue UV Lamp Indicator is still lit.
i.
Make sure the unit is disconnected from power and the lamp has cooled before starting
maintenance.
ii.
Open the Mast3rPur System by removing the screw on the bottom of the Upper Enclosure
Assembly, rotating it up and pushing it back to release it from the Assembly Pin.
iii.
Unplug the Lamp Connector Plug attached to the end of the UV Lamp and place the Upper
Enclosure Assembly in a safe place.
iv.
Slowly pull the UV Lamp out of the Quartz Tube by the white ceramic prong end.
DO NOT
TOUCH THE UV LAMP GLASS WITH YOUR BARE HANDS.
The oils on your hands can cause hot
spots on the lamp and shorten its life. If oil from your fingers is left on the lamp glass, clean
it off with a soft towel and rubbing alcohol. If you are removing an old lamp for replace-
ment, handle the lamp carefully and dispose properly (see Environmental Notice below).
v.
Make sure the two o-rings and the end cushion remain on the ceramic ends of the lamp as
it is set aside in a safe place.
