2 - Safety Precautions
The following instructions must be adhered to, in order to ensure a safe working environment and
the safety of the user.
The high luminance of the LED can cause severe damage to the eye if viewed directly.
ALWAYS wear suitable protective goggles when viewing the LED;
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 LED has cooled sufficiently before removal;
Due to the vast range of LED modules available it may appear possible that more powerful
LED’s can be used in the equipment than for which it was designed. Even when the unit will
physically accept a higher wattage LED, this substitution is not recommended and is
dangerous. This action will also void any warranties on the equipment.

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 3 off holes Ø6.4mm on a 108mm P.C.D.
A central hole Ø50mm will be required to accept the movement of the control handle. Make sure to
fit the Base-sealing gasket, when in the desired position bolt the searchlight firmly down. On an
uneven surface a suitable sealant maybe required to provide a weatherproof seal.
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 LED fitted be applied to the LED 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.
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) When wiring the negative supply, the direct connection to a battery or supply, or metal
hull/object, should be avoided. It is advisable to use a suitable commoning block or connection.
7) For ease of use a single pole switch, of the appropriate rating, should be fitted in a convenient
location. All cable lengths should be kept to a minimum.

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 cannot be adjusted.
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.
7- Fault Finding
All fault finding must be conducted by a competent person or qualified Electrical Engineer.
Failure of LED to light.
In the event of the LED failing to light the following steps should be taken:
1) Check that the supply is connected to the input of the LED and check all connections as per
the wiring diagram C27603. On operation if the lamp does not light, switch off supply and
check all fuses;

8 - Maintenance and Servicing
In order to prolong the service life and performance of your searchlight, the following maintenance
guidelines are recommended:
Maintenance checks should be conducted before every voyage or at least every three months;
Before checking, disconnect the equipment from the supply;
Visually inspect the condition of the equipment;
Any major or minor structural damage should be rectified immediately in order to reduce
sympathetic wear;
After inspection it may be necessary to clean the inside of the searchlight. The following
procedure should be adhered to:
Remove the front bezel;
Clean the front glass inside and out using a proprietary glass cleaner;
Clean the reflector if required;
It is advisable to check all seals and gaskets for signs of degradation. Renew if necessary;
Upon completing all maintenance requirements, the searchlight should be tested for full
working order (approximately 20 minutes).
If in any doubt as to the correct servicing procedures to adopt please contact your
distributor/agent or the manufacturer who will be able to advise the best course of action for
your product.
Notes for Lamp Fitting/Removal
Ensure all screws are retained carefully in a safe position;
Remove front bezel from searchlight by releasing the three latches;
Remove the three M4 hex head screws that fasten the reflector to the mirror pads.
Remove reflector & unclip lamp leads.
For aid see Diagram C27612. Remove lamp by undoing the 2 screw that hold the plates to
lampholder & then undoing the 4 screws that secure the plates together.
Replace the lamp by reversing the procedure.
It is IMPORTANT the heat dissipation belts on the rear of the lamp are spread to their
maximum (As shown below). Failure to do so will cause damage to the L.E.D
