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. 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.

The following table below indicates the maximum length of cable to be used for the AC supply

cable, from the control panel to 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 Guideline

A typical installation and connection routine for the searchlight is as follows:

Standard Models

Referring to wiring diagram C21164, a supply is fed into the Control Gear which in turn provides

the relevant supply to the searchlight head.

Cables to be connected by the customer: Mains cable into the Control Gear Enclosure (customer

to supply);

5 cores 1.5mmfrom Control Gear Enclosure into Searchlight Head (3 metres supplied –the

customer must provide a suitable junction box if these cables are to be extended).

Remote Focus Option Models

Referring to wiring diagram C21872, a supply is fed into the Control Gear Enclosure which

provides a common feed to the RF Control Unit, the control gear and the searchlight head.

Cables to be connected by the customer: Mains cable into the Control Gear Enclosure (customer

to supply);

5 cores 1.5mmfrom the Control Gear enclosure to the RF Unit (1.5 metres supplied –the

customer must provide a suitable junction box to extend these cables);

5 cores 1.5mmfrom the Control Gear Enclosure to the searchlight head (3 metres supplied –the

customer must provide a suitable junction box to extend these cables)

All internal wiring in the Control Gear Enclosure and the Searchlight head (and the RF unit if

chosen) is supplied pre-wired.

When operational, the output from the control gear should be approximately 100 volts at 13.8

amps.

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.

All control gear should be housed below deck/indoors. Never leave the control gear 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.

If using a remote focus option, the beam can be adjusted by pressing the yellow push button on the

RF Unit. The beam will move continuously through ‘spot’ to ‘flood’. In order to fix the beam type

simply release the button 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.

When bolting down the searchlight on an uneven surface, it is necessary to use a suitable sealant,

such as silicone, in order to ensure weather-proofed joint.

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 sleeve must be retained for re-use. Whenever

removing a lamp, the protective sleeve must always be used for safety reasons;

In all circumstances the lamp manufacturer’s data should be referred to when dealing with

lamps.
