Den Haan Rotterdam is a family-owned company established in 1922. Started as a small tinsmith, it has
evolved into a globally respected producer of navigation lights, searchlights, air horns and a wide range of
nautical lamps made from copper and brass. By introducing products with advanced LED-technology, DHR
has safeguarded a visibly safe future for marine vessels in all weather conditions.
With the 230RC-series searchlight, DHR introduces an entry level remote controlled LED searchlight. The
75W LED engine produces a color output of 5.000K and an intensity close to the same performance levels
of 1.000W halogen searchlights. Using the best available parabolic mirror reflectors on the market, a crisp
& clear spot with no visible stray light has been ensured. The 230RC is equipped with an unique bracket
design to realize an extreme downward vertical angle. This is specifically useful for close range targets.
Positions on high structures or foremasts of inland navigation vessels, where high angles up to 60° are
desired, the 230RC is the answer.

1. MOUNTING INSTRUCTIONS
Place the control panel inside the wheelhouse, where it is protected against weather influences. The panel
has been designed in order to be flush-mounted in an instrument cabinet, as shown in the illustration below.
The minimum required space for the panel inside the console 50 mm (4.33 inch).
Install the searchlight in a horizontal upright position with sufficient space around the head of the search-
light to ensure it can move freely. The dimensions can be found on page 9.

All dimensions in mm (inch)
Fasteners
• The permissible torque should be 8 Nm (5.9 lbfft)
• Use only A4-grade stainless steel
Caution!
Even though the housing is made of corrosion resistant materials, galvanic corrosion may still occur. To
prevent galvanic corrosion use the supplied insulation sleeves to isolate the aluminium housing from
other metal parts.

Install the electrical wiring according to the wiring diagrams showed on pages 11 - 14. Keep the distance
between the power supply and halogen lamp as short as possible. Long wires will increase a voltage drop
near the halogen lamp, which affects the light output.
ØD
Cable
• Prefered diameter D is 7 - 12 mm (0.28 - 0.47 inch)
• Material: Neoprene H07RN-F
Cable too tight!
This gives unwanted stress at the sealing of the
cable gland and water ingress will occur.
Include cable slack at the entering
point of the cable gland
Replacing cable gland
• Use gasket between housing
and cable gland
• Tighten firmly (6Nm / 4.4 lbfft)
with wrench
Remove the plug before placing the cable.
If no cable is connected, leave the plug in place!
Note
The cable glands on the searchlight prevent water ingress. Do not use (electrical) tape to cover the
cable where it enters the cable gland as this will cause water ingress. Do not use a rubber or shrink-
able cover on the cable gland to improve water tightness.

6. MAINTENANCE AND CORRECT USE
Tips for correct use
• Do not overheat the searchlight - max. burning time 20 min.
• Switch off the searchlight immediately after use, this increases the life
expectancy of the bulb
• Do not light-up objects closer than 2 metres
• Clean the searchlight regularly with water
• Do not point the light beam at the eyes of humans or animals
Preventive maintenance
Clean the searchlight with clean water regularly. Do not use any aggressive cleaning agents. At least twice
a year rub the dirt wiper, on top of the motor housing (see drawing below), in with silicone grease.
Safety notes
• Handle with care
• Turn off main power
• Warning, lamp is hot
• Do not touch the lamp with bare hands
