Cleaning the Reflector

To quickly clean the reflector, remove the lens tube and clean the dust from the reflector with a blast

of oil-free air. You may also wipe the reflector with a clean lint-free cloth. If either method is not

sufficient, follow these steps.

Step 1:

To protect the lamp housing during cleaning, remove the lamp housing by loosening the

knurled bolt and pulling the housing straight out. See

Figure 3

Step 2:

Remove the barrel rotation knob located at the bottom of the barrel (see

Figure 1

). Use

a Phillips screwdriver to remove the retainer bolt located on top of the reflector housing.

Step 3:

Rotate the barrel 45° in either direction. Carefully remove the barrel from the reflector

housing.

Step 4:

Remove dust with a blast of oil-free air or wipe with a clean, lint-free cloth. Isopropyl

alcohol, distilled water or a 50%-50% mixture of each can be used to clean the glass

surface.

Step 5:

Gently wipe the reflector.

Step 6:

Insert the barrel into the reflector housing with the iris/pattern slot on top. Align the

triangles on both parts.

Step 7:

While gently pressing in, rotate the barrel 45° clockwise until it sets into position, then

rotate the barrel counterclockwise 45°. The barrel should be firmly attached and the

triangles should be aligned.

Step 8:

Reinstall the barrel rotation knob and tighten the retainer bolt.

Step 9:

Reinstall the lamp housing and tighten the knurled bolt.

Portable appliance test (PAT)

The Portable Appliance Test is a set of tests that must be administered to electrical equipment in

the UK and some locations in Europe to ensure safety.The tests are typically carried out using a

small PAT device. The PAT device connects to a power source and then attaches to the product

via an electrical outlet and test probes. The PAT provides a simple pass or fail result, allowing rapid

testing of large inventories.

Source Four CE luminaires include a specific PAT point where the test clip is attached, as shown

Figure 15

. PAT tests should be performed by a qualified technician. Your local regulatory

authority has guidelines on the testing frequency.

W A R N I N G :

Unplug the luminaire before attempting to clean the reflector.
