18 Component removal & reinstallation
1. Inspect the front glass seal for damage before refitting. Replacement front glasses and seals are
available from Martin Architectural dealers (front glass: p/n 41700007, front glass seal: p/n
20600441).
2. Inspect the six countersunk Allen screws from the trim ring before reuse. Threads must be clean
and undamaged. Two spare screws are supplied with the fixture. Replacement screws are
available from Martin Architectural dealers (p/n: 08111314)
3. Refit the lens by lowering it into the housing, making sure that the screw in the seating engages
in the notch in the lens flange.
4. Place the front glass complete with its seal in the top of the housing and place the trim ring over
the front glass.
5. To make future service easier, apply a small amount of copper-based or silicone grease to the
threads of the trim ring screws before insertion.
6. See illustration below. Gradually cross-tighten the trim ring screws in the sequence illustrated to
1.8 Nm/1.3 ft-lbs.
Important! Cross-tighten gradually. Do not exceed the maximum torque of 1.8 Nm/1.3 ft-lbs., or
you may distort the trim ring and damage the seal. This will impair the Inground
200’s waterproof properties and invalidate the product warranty.
Lamp module: removal and refitting
This section describes removal and refitting of the lamp module to gain access to the connections
and PCB/power compartments at the bottom of the fixture. If you need to replace the lamp, please
refer to the Inground 200 User Manual.
To remove the lamp module:
1. Isolate the Inground 200 from AC power and allow to cool for at least 15 minutes.
2. Remove the front glass with seal and lens (see “Front glass and lens: removal and refitting” on
page 17).
3. Do not loosen the beam adjustment screws and avoid disturbing the beam adjustment settings.
Holding the lamp module by the beam adjustment ring, gently lift the whole module upwards until
it is clear of the housing. Note the positions of the lamp module wiring connectors, then
disconnect them and lift the lamp module out of the housing.
To refit the lamp module:
1. Reconnect the lamp module wiring connectors.
2. Note the position of the screw in the lamp module seating in the housing. Lower the lamp module
into the housing, rotating it if necessary so that the notch in the top of the lamp module engages
with the screw. The lamp module is now correctly oriented.
3. If beam settings have been disturbed, readjust the beam (see “Beam adjustment” on page 16).
4. Refit the lens, front glass with its seal and trim ring, and cross-tighten the trim ring screws
gradually to 1.8 Nm/1.3 ft-lbs (see “Front glass and lens: removal and refitting” on page 17).
