If the existing entry is of the G1/2 thread type, replace the existing pipe and
junction box cover as well (marked with ☆in Fig. 6 if the existing junction
box is SEIWA's product).
For the G3/4 thread entry, remove the existing pipe and screw the supplied pipe
into the existing junction box. For the G1 thread entry, use the existing pipe as it
is.

CONTACT DETAILS
Never touch LED light sources and their surroundings.
The light sources and their surroundings are very hot, so an accidental touch might cause a burn.
A lighting fitting has a service life. A product which has been used for eight to ten years may have degraded internal parts
even if it looks normal. For safety and energy saving, we recommend you check and replace it. The LED module design life is
6,0000 hours (different from the lighting fitting life) when used at an ambient temperature of 30°C, 10 hours per day, 3,000
hours per year. If used at a higher temperature or more hours per year, the life would be shortened. Have a specialist
inspect the product every three years. If used for an extended period without inspection, a smoke, fire, or electric shock
might result.
