Features • Light source: 175-watt Metal Halide bulb with 4600° K Reflector
•
Lamp replacement: The unit features rear access allowing simple replacement
of lamps without removing the fitting • Thermal management: The housing has been carefully designed with internal air gap and special venting/convection to direct heat away from that part of the housing in contact with the boat hull or other mounting surface. The housing locking ring has also been designed as a heat sink to further dissipate heat effectively away from where it is not wanted.
•
Lamp housing: The lamp housing is manufactured from naval bronze machined to
the highest standards.
•
Seals: All the seals are made from high temperature silicone rubber for
reliability.
•
Lens: Our lens is made from BoroTrans
sm
for high temperatures and
harsh environments.
•
Installation: The fixture is supplied with user friendly fixing hardware
provided. There is a leveling ring supplied to allow fitment where the
inner surface may not be parallel to the outside surface.
Specifications (Fixture & Lamp Assembly)
• Body:
316TI Stainless Steel Specifications ELECTRICAL
•
Input voltage: Dual ballast 120 (1 phase); 240 (1 phase) volts AC, Running
current 1.5-0.75 amps
Operation and Maintenance • WARNING: Never operate the light out of water as the water provides necessary cooling. The lens bezel must be completely submerged at all times. Avoid operating the light when the boat is planning as often times this raises the fixture bezel above the water-line and thus diminishing the cooling effect of the water. Generally, Halogen lamps have a service life of approximately 2,000 hours. This may vary depending on the number of restarts and other factors. Replacing the Lamp • Isolate main power and assure it cannot be re energized accidentally by other persons. • Allow the lamp and housing to cool down (minimum 20 minutes). Check carefully that the unit has cooled sufficiently before attempting to open the housing.• Using your hand, loosen the rear lock ring, (turning counter clockwise). • Once the ring is free, carefully withdraw the lamp assembly from the housing. • NOTE: Ensure the area local to the light is relatively dry, thus ensuring bilge water can not enter the opened housing. Also ensure the withdrawn lamp assembly DOES NOT comes in contact with water at any time. It MUST remain clean and dry at all times. Should the assembly come in contact with water, contact your nearest supplier for further advice. Do not re-assemble and re-energize.• Hold the cable end of the lamp assembly and rotate (counter clockwise) the reflector case. Unscrew until the lamp is exposed.• Carefully withdraw the spent lamp from its socket. It is recommended to use a glove or thick cloth as the lamp may shatter causing injury.• Inspect the lamp socket carefully for any signs of damage or corrosion. Basic cleaning may be carried out using dried, compressed air. DO NOT spray contact cleaner into any part of the lamp holder assembly.• Carefully remove new lamp from its packing. Using a clean cloth, fit the new lamp into the 4 Socket. IMPORTANT! Ensure the new lamp is wiped totally clean of any dirt or fingerprints. Failure to do so will result in premature lamp burn-out.• Inspect the housing to ensure it is completely clean and dry. The lens may be cleaned if necessary using a soft cloth on the end of a wooden dowel or similar. Re inspect after cleaning to ensure no cloth or other cleaning fibers remain inside the housing. NEVER! Spray lubricants, degreasing agents or other similar products into the housing. Carefully re-fit the lamp assembly into the housing ensuring the front end of the reflector case locates correctly into the front end of the lamp housing. This can be felt by moving the assembly around until it drops neatly into position with the rear end cap snug against the silicone seal.• Re-fit the outer lock ring. Again it is recommended to apply a thin layer of silicone based grease to the thread and surface in contact with the end cap.• NOTE: at no point is it necessary to loosen the cable gland nut; however it should be checked to insure it is secure and snug around cable, DO not pull excessively on the cable.
Other Maintenance
•
Check to ensure the underwater lens is clean and free of marine growth. It
may be cleaned using a nylon brush or plastic scraper.
•
Replacement parts and accessories: A full range of Replacement parts and
accessories are available. Please contact your supplier for any
requirements.
•
Should there be a malfunction for any reason, please consult your nearest
agent or Aqua Lights directly. The housing should not be opened under any
circumstances unless by a suitably qualified and authorized technician.
Safety and General Information
THE FOLLOWING INFORMATION IS IMPORTANT TO THE SAFE OPERATION OF THIS
EQUIPMENT, ACCORDINGLY MUST BE OBSERVED AND ACTIONED AS NECESSARY.
•
This Light should only be installed by suitably trained trades persons
experienced in the fitting of through hull equipment and marine Mains
Voltage AC electrical systems.
•
It is important that the housing is electrically bonded to the vessels
cathodic protection grounding system. Failure to solidly ground will result
in corrosion, leading to serious damage or loss of vessel, property and
life. Regular checks/testing must be carried out to ensure the metal housing
is electrically bonded to the vessels cathodic protection grid.
•
If the housing shows signs of excessive corrosion (other than surface
contamination) or physical damage, the vessel should be hauled so a complete
assessment can be performed. Any signs of water ingress must be addressed
immediately.
•
As this equipment operates on mains voltages, it is of the utmost importance
that all equipment is maintained in first rate working order at all times.
Regular inspections should be carried out to ensure all wiring is in good
condition, clear of wet areas and not exposed to mechanical interference.
•
Any suspect equipment must be repaired or replace.
•
The Lens and Bezel have been carefully designed with a smooth, flush surface to
allow easy cleaning.
•
Never operate the vessel with the lamp housing end cap removed.
