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.

2.5 Air inlet and Exhaust Cowls

Twister enclosures are supplied with two plastic cowls and filters for the air inlet and exhaust vents. Use of the

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

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.

Twister Enclosure User Manual page 8

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.

1 Before 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.

2 Two 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.

1 Wrap the chimney around the fan, and fasten with

the two plastic zip-ties supplied. You may trim the

chimney with sharp scissors as needed.

2 When 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

Twister Enclosure User Manual page 16

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 17

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 18

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.

Twister Enclosure User Manual page 19

7 Troubleshooting

This is a guide to the general symptoms, problems, and solutions that may occur during the

usage of your enclosure. However, it is important to remember that problems may occur within

the equipment itself and these must also be considered.

Equipment does not have power.

Check power supply wiring and voltage.

Fan is not spinning

Fan cord may have become disconnected. Check connections between fan and cord.

Fan may be obstructed. Shut off power to enclosure and check for obstructions. Turn power back

on to see if fan will start spinning. If fan does not turn then enclosure is not receiving power.

Turn off all power and check wiring. If the wiring is correct, contact technical support.

Equipment does not have power.

Check equipment power switch. If switch is on, check wiring and supply switch/circuit breaker.

Equipment turns on and off repeatedly over short span of time.

Check that vent areas and airways are clear. If so, ambient temperature may be too high, or

equipment may have internal problem.

Excessive water in enclosure.

Seal leak. Repair with silicone sealant, or replace seal.
