2 - Safety Precautions
The following instructions must be adhered to, in order to ensure a safe working environment and
the safety of the user.
Note: When unpacking or manoeuvring the searchlight into its fixing position, suitable
lifting points must be used in order to prevent damage to the equipment or personal injury.
Because of the high internal pressure within the lamp, there is a risk of explosion in either a hot
or cold state;
During operation this lamp emits intense UV radiation which is harmful to the eyes and skin.
Suitable protection should be worn;
The high luminance of the arc can cause severe damage to the eye if viewed directly.
ALWAYS wear suitable protective goggles when viewing the lamp;
Always use protective sleeves supplied with the lamp;
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;
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 disposing of lamps, return the lamp, via the supplier, to the lamp manufacturer in its
complete packaging;
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 manufacturer’s technical data when dealing with lamps.

4 - Unpacking and Installation Instructions
The following instructions should be read and fully understood prior to installing the equipment to
ensure that the correct procedures are followed and all safety precautions are observed.
Note: If the equipment has been in storage for a considerable amount of time, it is advisable
to conduct a routine maintenance check on all parts before installation.
Safety Precautions
This equipment should not be connected to an electrical supply before being installed. Installation
procedures should be adhered to in order to ensure a safe working environment and reduce the
risk of damage or personal injury.
Preparing the Mounting Position
Mark out and drill the fixing holes through the deck and bolt the searchlight base securely. On an
uneven surface it is necessary to use a sealant, such as silicone, in order to ensure a weatherproof
joint. If anti-vibration mounts are to be fitted, the fixing holes for the mounts should also be marked
out and drilled. Prior to manoeuvring the searchlight into its’ fixing position, the AV mounts should
be fitted to the base. When in the desired position, bolt the searchlight firmly down.

5 - Electrical Installation
For safety purposes, only competent personnel should perform the electrical installation. All
equipment should be installed to current Electrical Regulations and Standards.
In order to obtain the maximum light output from the searchlight, it is essential that the full
operating voltage of the lamp fitted be applied to the lampholder contacts.
Method of Electrical Connection
1) Disconnect the supply before working on the electrical system;
2) The searchlight must be connected to a fused electrical supply, using suitably sized cable;
3) If the searchlight is located a considerable distance from the supply, provision must be made in
the cable size in order to overcome the voltage drop.
The Control Gear should NOT be positioned know more then 5 meters away from the
Searchlight.
4) Whenever possible cable terminations should be made below deck and with approved terminal
devices;
5) If a spare auxiliary fuse or circuit breaker is not available, one of the correct type and rating
should be fitted and connected to a positive supply. It is advisable to locate a bus bar or main
connection and avoid any direct connection to the supply:
6) For 110/220v AC products, the following colour coding system should be used for the customer
supply cable:
Brown - Live
Blue - Negative
Green/Yellow - Earth
Note: This equipment must be earthed.

Installation Guidelines
A typical installation and connection routine for the FH560D 2.5Kw searchlight is as follows:
Referring to wiring diagram C26458, a supply is fed to the Junction box, which then provides a
common feed to the Switch box, Power Supply Unit and the Searchlight.
The mains supply lead, power supply unit, switch box & searchlight is pre-wired with 3 metres of
cable to the junction box.
When the light is in operation, the output from the PSU should be approximately 115v ac at
25.6amps.
Basic Operation
When the searchlight is switched on a supply is fed to the PSU and linked to the ignitor. Also from
the PSU, a dc output is fed to the lamp. The ignitor ionises the gas within the lamp and this strikes
the light.
NOTE:
Ensure the PSU red remote switch is set in the on position.

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 PSU should be housed below deck/in doors. Never leave the PSU exposed to weather
conditions.
The beam of the searchlight can be adjusted to give a variety of beam types. Using the lampholder
focus wheel, the desired beam can be achieved for any particular application.
Using the template provided mark out and drill the fixing holes through the deck. When bolting
down the searchlight on an uneven surface, it is necessary to use suitable sealant, such as
silicone, in order to ensure a weatherproof joint.
The heaters specified on this equipment are self-regulating and will shut off when they reach the
dew point temperature.
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 sleeve 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;
Ensure that the power rating of the lamp to be fitted is suitable for the lamphouse and
power supply equipment;
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;
When inserting or removing a lamp, always hold it securely by its’ base in order to
prevent breakage between base and bulb;
The lampholder must not exercise mechanical tensions on the lamp, neither during
insertion or operation. Contacts must not discolour during use;
For safety reasons, the lamp should be replaced once it has reached its’ average life,
and not later than 1.25 times the stated life. With continuing use the risk of the lamp
exploding increases due to alterations within the quartz;
Before the protective sleeve 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;
All packaging and the protective jacket must be retained for re-use. Whenever
removing a lamp, the protective jacket must always be used for safety reasons;
In all circumstances the lamp manufacturer’s data should be referred to when dealing
with lamps.
