1. Remove the Enclosure from the Installation Site
This upgrade must be performed by an authorized Tempest Lighting service representative in
order to qualify for the 12-months warranty from the date of re-installation on site. The work
may be performed by trained technicians, using normally-available hand tools. Tempest
Lighting strongly recommends performing the upgrade in a workshop, and not on site.
 Do not open any electrical boxes until power has been shut off to all supply lines to the
enclosure (including the one powering the luminaire).
1. Open the original enclosure and remove the luminaire for separate service/cleaning
2. Open the Existing DEC cover in the base of the enclosure and disconnect power feeder
wires. Note whether the enclosure is fed with a single or dual supply (one feed for the
enclosure, one for the fixture). If so, identify and tag wires correctly for re-installation.
3. Disconnect DMX wiring entering the enclosure
4. Remove electrical fittings under enclosure (they will not be re-used) and disconnect feeder
conduits
5. Remove the mounting hardware attaching the Tornado Unistruts to the installation, and
carefully remove the Tornado base. DO NOT ATTEMPT TO DO THIS WITH FEWER THAN TWO
PEOPLE, OR IN BAD WEATHER.
2. Strip down and Update the Top Assembly
a. Back in the shop, strip down as follows
b. Top Assembly – do not remove the globe from the top fiberglass ring unless the
globe is damaged. In this case refer to instructions below for replacing globe.
Check the silicone seal around the globe and clean out and touch up as needed.
c. Remove the four latches and hardware and discard.
d. Remove the existing rubber seal around the top ring and discard.
e. This is a good time to CLEAN the top assembly – use mild detergent and no
abrasives. Use a proprietary acrylic polish to take any minor scuffs out of the globe.
f. Carefully install the new rubber seal, tapping home with a rubber mallet, and cut to
length with metal shears. Glue join with outdoor-rated silicone.
g. Mount the four top marine latches (they have three mounting holes) to the top ring.
Note that the stainless/rubber cone washer sits under the latch plate, and with its
rubber side to the fiberglass, to prevent water ingress.
3. IMPORTANT – check the height of the fixture brackets
a. Measure from the inside of the base (fiberglass) to the top of the two Z-brackets
that support the fixture (they’re bolted down onto the DEC box). Make a note of
this dimension – the retrofit kits are universal, and you’ll need to adjust the height
later.
