2.4 Mounting Orientation
All Twister enclosures are designed to be mounted either base-down, base-up or horizontal, on a solid structure,
using the mounting hardware described above.
Base Up Base Down Horizontal
(see 2.5.1 below) (see 2.5.2 below) (see 2.5.3below)
Note that the air inlet and exhaust cowls are trimmed and oriented differently, depending on the mounting
orientation. See next section for detailed instructions.
2.4.1 Weep Holes
For Base up and horizontal installation, it is necessary to drill a drainage hole at the lowest point of the globe.
USE ONLY THE SPECIAL ACRYLIC TAPERED DRILL BIT SUPPLIED WITH YOUR TWISTER MANUAL. A regular
bit may crack the globe. Tempest Lighting Inc. accepts no responsibility for such damage.
NOTE:
Horizontal enclosures –
be sure to always
replace the globe with
the weep holes down.

Twister Enclosure User Manual page 8
2.5 Air inlet and Exhaust Cowls

cowls differs according to the orientation of the enclosures
2.5.1 Base-Up Installation
Insert the two filters into the cowl
slots.
Insert two rain guards between the
plastic cowl and the Twister base as
shown
Mount the cowls and rain guards onto
the Twister base plate, using the
screws provided

Twister Enclosure User Manual page 9
2.6 Air Filters
Note that both cowls are fitted with electrostatic air filters, to prevent ingress of dust and insects.
Both filters must always be in place.
You will need to remove the filters periodically for cleaning. How often will depend on local conditions. We
recommend checking every three months and then determining frequency of cleaning depending on what you
find.
To clean the filters, simply run them under a tap or water hose. Replace carefully between the ribs in the air
cowls. Cowls do not need to be removed –this picture is for illustration only.
2.7 Fan Chimney (Twister 1900/1950)
The Fan Chimney is supplied with larger Twister enclosures and is required for use with luminaires using the
Philips 5R and 15R lamp, which is very sensitive to elevated temperatures. The fan chimney ducts the
incoming airflow from the fan into the top of the globe for more effective cooling.
Wrap the fan chimney around the fan, high side outside, and secure using the zip ties provided.
The fan chimney is soft, and will conform to the base of the luminaire as well as to the inside of the globe
assembly. It may be trimmed with sharp scissors if
needed.

3 Wiring
3.1 Electrical Preparation
 All electrical work must be carried out by a properly licensed electrician. Failure to observe this
point will void the factory warranty for the Tempest Enclosure and possibly the equipment housed
inside.
1Before starting work, switch off power to the branch circuit, carefully following lockout and tag-out
procedures. Failure to do so could cause serious injury or death.
2Two electrical junction boxes will be required within a short distance of the Twister enclosure for:
•AC supply wiring
•DMX control wiring
Your Twister enclosure is supplied fitted with two cable entry points, for Power and DMX signal cables.
The cable entries are suitable for use with standard conduit fittings. US size ½”, international 20mm.
Tempest recommends the use of flexible, outdoor-rated conduit for the last few feet (1m) to the enclosure.
All junction boxes must be installed in accordance with local electrical codes and should be located near the
permanent installation of the enclosure. Each junction box requires a length of flexible conduit, long
enough to reach from the junction box to the enclosure conduit fittings. Leave slack for positioning of
enclosure, and enough space behind the enclosure for ventilation.
The AC supply must be protected by a fuse or circuit breaker of a rating suitable for the equipment.
The user may connect the fan and the equipment to the same switched supply, or run them separately,
according to need (see below).
Note that for temporary installation, the conduit fittings may be replaced with outdoor-rated cable entry
glands, at the user’s discretion.

MiniDEC Operation
The MiniDEC controller monitors current going to the light fixture inside the Twister enclosure, and also heat inside
the enclosure. When it detects that the light is on and/or the internal temperature is getting warm, MiniDEC runs
the enclosure fan. For best results, enclosures must be connected to live power at all times.
MiniDEC Operation is completely automatic.
Summary: MiniDEC detects current to light >1.5amps Fan on
MiniDEC detects current to light drop below 1amp 5-minute fan cool-down, then fan off
MiniDEC detects temperature 25-35°C (77-95°F) Pulse fan to change air every minute
MiniDEC detects temperature >35°C (95°F) Switch Fan on
MiniDEC LED Indicator
For information and Faultfinding there is an LED indicator on the MiniDEC control board. Function as follows:
LED OFF: MiniDEC is not powered, or power supply has failed.
LED ON: MiniDEC is functioning normally and luminaire power is < 1amp
LED blinking slowly: Luminaire Power > 1 amp, fan on
LED blinking rapidly: Luminaire power has dropped below 1amp. Fan is running for five minutes
for five-minute cool-down

4.4 Use of Twister 1900 Fan Chimney
The fan chimney accessory is supplied with the Twister 1900 enclosure to assist air
circulation in cases where the luminaire base tends to obstruct airflow, or where
particularly temperature-sensitive lamps are used, such as the Philips Platinum
series. The chimney accessory is only needed if the luminaire is overheating, and is
not required for most luminaires.
The Chimney is a flexible duct that helps the incoming cool air from the fan blow
up to the top of the globe.
1Wrap the chimney around the fan, and fasten with
the two plastic zip-ties supplied. You may trim the
chimney with sharp scissors as needed.
2When placing the globe on the Twister base, take
care that the chimney is INSIDE the join between
the globe and the aluminum globe collar. The
chimney will spread out to conform to the space
available

5 Operation
While there are no specific operational actions required for normal use, the following points should be kept in mind.
The enclosure should be connected to a live circuit at all times except when maintenance is being carried
out.
Unless the enclosure or equipment is undergoing routine maintenance, the enclosure should be closed and
securely latched at all times.
Only authorized personnel should open the enclosure (see maintenance warnings in the next chapter).

Twister Enclosure User Manual page 19
6 Routine Maintenance
It is very important to perform routine maintenance on both the enclosure and the equipment
inside it. Failure to do so may reduce lifetime for both the enclosure and the equipment.
Note
Maintenance schedules depend on location and environment. The intervals given here are
general minimum guidelines. It is up to the user to judge whether maintenance should be carried
out more frequently. We recommend doing these tasks no less often than mentioned here.
Safety
As the enclosure is a powered unit with moving parts, it is necessary to keep safety in mind while
performing routine maintenance. Although maintenance can be performed while the enclosure is
powered, it is safer to carry it out with the power disconnected with proper lockout and tag out
procedures followed.
Be aware that once the enclosure has had power applied to it, the fan will start to turn. Make
sure that your hands are clear of the fan before applying power to the enclosure.
Only authorized personnel should perform maintenance on the enclosure or equipment
Do not service the unit in the rain or other adverse weather conditions (snow, sleet, high winds,
etc.).
Inspection Checklist: - Every Three (3) Months
Glass should be clean and free of cracks
Enclosure should be free of debris both inside and out
Bolts and tie-down straps should be tight
Rubber seals should be in good condition. Check seals inside and out for gaps.
Fan should be functioning and not making excessive noise
Filters should be clean
Drainage holes must be free of obstructions
Air Filter - Every Three (3) Months
Both air filters should be removed and cleaned on a regular basis. To
remove filter, pull pull it directly out of the intake vent. The filters can be
cleaned by running water from a hose and do not require any special
solution.
To reinstall, carefully push filter back into the cowl molding. The filter
should sit snugly between the cowl ribs.

Twister Enclosure User Manual page 20
Case - As Needed
The outside of the case should be cleaned as needed. The case should be cleaned with a wet
cloth and mild detergent (if necessary). Do not use a direct spray from a hose to clean the case.
Globe –As Needed
Clean using a proprietary acrylic cleaning solution or a mild detergent, and wipe dry. Use only
soft, lint-free cloths for globe cleaning. Never use an abrasive cleaner.
Equipment
Review the manufacturer's instructions for proper maintenance of your Luminaire. Remember,
the enclosure simply protects the equipment inside it and is not a substitute for regular
maintenance.
