2 - Safety Precautions
The following instructions must be adhered to, in order to ensure a safe working environment and
the safety of the user.
Prevent rain, snow, condensation and water droplets from contacting the lamp as this may
cause bulb failure and possible shattering;
Because of the high internal pressure in excess of atmospheric. Whilst the construction is
inherently strong, there is a slight risk of the bulb shattering;
Never look directly into an illuminated searchlight as this may cause severe damage to
eyesight. If it is necessary to inspect a lamp whilst in operation, always wear suitable protective
goggles;
Should it be necessary to examine the lamp with the front bezel removed, always use a
protective shield and wear goggles to ensure a safe working environment;
Never attempt to clean a lamp whilst in use;
Searchlights get hot. Never touch the unit when lit and always allow 15 to 20 minutes for
cooling down after turning the searchlight off;
Never place anything on or cover the searchlight when in use;
Ensure the lamp has cooled sufficiently before removal;
If undue force appears necessary to remove the lamp, the equipment should be inspected by a
competent person or contact the manufacturer;
When breaking a lamp for disposal, care must be taken to ensure the glass fragments are
safely contained. This operation must be performed out of doors in free air. In all
circumstances refer to the lamp manufacturers instructions packed with the lamp;
Due to the vast range of lamps available it may appear possible that more powerful lamps can
be used in the equipment than for which it was designed. Even when the unit will physically
accept a higher wattage or voltage lamp, this substitution is not recommended and is
dangerous. This action will also void any warranties on the equipment.
Always refer to the lamp manufacturers technical data when dealing with lamps.

6 - Operating Instructions
This equipment is designed for use out of doors, in free air. Never place anything on, or cover, the
searchlight when in use as this may present a hazard.
The beam of the searchlight can be adjusted to give a 40° split, simply release the external lock
wheel and adjust the lever to achieve the desired beam split required.
In event of lamp failure, the changeover mechanism can be activated by rotating the lever 180°,
which then switches power to the second lamp. The second lamp may take a few seconds to
achieve full brightness.
This product should not be used for any purpose other than for which it was designed. Any
modifications to the product should not be undertaken without consulting the manufacturer.
Setting to Work
Safe service in use necessitates the strict observance of the following precautions.
Any article fabricated from quartz or glass is inherently fragile and care should
therefore be taken, at all times, when handling lamps;
Eye protection must be worn when handling lamps that have been removed from their
packaging materials. The protective jacket should not be removed from the lamp for
safety reasons, as there is a remote possibility of the lamp shattering violently,
especially if it is subjected to mechanical shock or vibration;
Always isolate the equipment from the supply before inserting a lamp;
Before inserting the lamp ensure that all contacts are clean. Contacts must be
renewed at the slightest sign of corrosion. Sanding or filing down corroded areas is not
recommended as this will only make the conducting surface between the pin and
lampholder smaller, thus causing the lamp to overheat;
Do not twist or bend the fused quartz bulb when fitting the lamp as mechanical
stresses MUST be avoided;
The lamp must be capable of unimpeded expansion when it warms up to operating
temperature. Mechanical forces must not be applied to the fused quartz bulb;
Before the protective jacket is removed, suitable protection must be worn i.e face mask
and gloves with wrist protection;
Never touch the quartz bulb with bare hands, as fingerprints will make the glass cloudy
and cause a severe loss of light. This may also cause recrystallisation and thus
weaken the bulb material. Should the bulb be inadvertently touched, remove
fingerprints with methylated spirit and a clean, soft paper towel. The bulb should then
be wiped with distilled water. NOTE: ALWAYS WEAR MASK AND GLOVES DURING
CLEANING);
In all circumstances the lamp manufacturers data should be referred to when dealing with
lamps.

When fitting the lamp:
-Always isolate the equipment from the supply when inserting a lamp;
-Ensure the circuit is suitably fused;
-Ensure the lamp is of the correct power rating and type;
-Check lampholder is in good condition. If the contacts show any sign of corrosion, replace the
lampholder;
-Check the lampholder is in a good dry condition. Never allow water to collect in the lamp fitting
or come into contact with the lamp.
To fit the lamp:
-Loosen all the latches from the front of the searchlight by pressing down the safety catch and
releasing the clip, remove the bezel and glass and store in a safe place;
-Cut open one end of the protective sleeve surrounding the lamp;
-Using the sleeve to prevent the fingers coming into contact with the lamp, position the two pins
above the holes in the lampholder;
-Gently push the lamp into the lampholder and remove the protective sleeve;
Testing
Upon correct installation and connection to an electrical supply, the equipment can be tested in
order to ensure its’ correct performance. A competent person with some knowledge of electrical
equipment must carry out this work.
Equipment required: Multimeter with leads
Ammeter
Using the equation P=VI, the approximate power output of the equipment can be calculated in the
following way:
-Using the multimeter, take a voltage reading;
-Using the ammeter, take an amp reading from the live cable to the lamp;
-Multiply these figures together to give an approximate wattage (Power output).
For example:
Using a 240v 1000w Tungsten halogen lamp:
Voltage reading = 240v; Amps reading = 4 amps
Therefore, Wattage = 240 x 4 = 960 watts

7- Fault Finding
All fault finding must be conducted by a competent person or qualified Electrical Engineer.
Failure of Lamp to light
Causes:
1) Power not supplied;
2) Fuse blown;
3) Failed lamp
Remedy:
1) Check voltage at supply. If supply is not present the fault is at the customer supply. If power is
present, see remedy 2;
2) Check fuse for visual failure. If none noticeable check fuse for continuity using a multimeter. If
fuse found to be faulty, replace with new part and test equipment again for correct working
order. If found to be working correctly see remedy 3;
3) Firstly, check supply at rear bulkhead terminal rail (within searchlight barrel). If supply is
present, disconnect unit from power supply before removing the lamp. If the lamp envelope is
discoloured, replace the lamp. Replace lamp ensuring all precautions and instructions
previously outlined in this manual are adhered to.
4) Check that the fans in the power supply box are working correctly, if not check that the supply
is present if so, replace fan.
5) Check input supply to the power supply unit is correct.
6) Check that the switch on the searchlight barrel is working correctly, if not check that the supply
is present if so, replace switch.
