Maintenance and service

Disconnect power to the unit before carrying out any maintenance,

repair or service work and ensure that it cannot be reconnected unin-

tentionally during this time.

When installing bulbs, follow these instructions:

10" Sun Tunnels - R20, 50 Watt max. Daylight bulb or R30, 15 Watt

compact ﬂ orescent Flood.

14" Sun Tunnels - R20, 75 Watt max. Daylight bulb or R30, 18 Watt

compact ﬂ orescent Flood.

21"/22" Sun Tunnels - R20, 75 Watt max. Daylight bulb or R30, 18

Watt compact ﬂ orescent Flood.

If the light ﬁ xture ﬂ ickers or turns oﬀ and then comes back on after a

period of time, then the chosen bulb produces too much heat and a

lesser wattage bulb should be chosen.
