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.
◼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 the fixing holes through the deck, using the template provided. 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.
In the case of cabin control models, a centre hole is also required to allow the mechanism to pass through.
Fit the ‘O’ ring in position and bolt the searchlight down securely. On an uneven surface it is necessary to
use a suitable sealant, such as silicone, to ensure a weatherproofed joint.
For cabin control models it is necessary to remove the Underdeck control assembly prior to installation.
Using the Allen key provided, the five grub screws on the Underdeck mechanism should be loosened to
allow the Underdeck control assembly to be removed. The outer tube can now be positioned through the
centre hole. The searchlight base can now be securely fixed as stated above.
Upon installation, re-assemble the Underdeck control mechanism ensuring the grub screws are secure
and the mechanism operates correctly.

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) 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
Installation Guideline
A typical installation and connection routine for the L300 110W LED searchlight is as follows:
Referring to wiring diagram C27730, a supply is fed into the control gear enclosure, which then provides a
common feed to the searchlight.
Cables required to be connected by the customer: -
3 cores 1.5mm cable from the Control Gear to the Searchlight,
(Customer may need to provide a suitable junction box to this cable, 3 metres supplied).
The Mains cable to the Control Gear is to be supplied by the customer.

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 searchlight can be positioned using the elevation and base plate lockwheels. When in the desired
position the lockwheels should be securely fastened to maintain position.
The beam of the searchlight can be adjusted to give a variety of beam types. Using the focus knob on the
underside of the searchlight, the desired beam can be achieved for any particular application. The beam
will move through ‘spot’ to ‘flood’. In order to fix the beam type; simply release the knob at the desired
position
Using the template provided mark out and drill the fixing holes through the deck or cabin roof. In case of
cabin control models, a centre hole is also required to allow the mechanism to pass through.
On an uneven surface when bolting down the searchlight it is necessary to use a suitable sealant, such as
silicone, in order to ensure weather proofed joint.
Please note that if an optional heater is fitted, it is advisable to leave the heater permanently in the ‘ON’
position in order to remove any condensation. The heater specified on this equipment is self-regulating
and will shut off when the dew point temperature is reached.
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.
