Lamps are not interchangeable.
You must install the correct lamp in the
fixture.
Do not install a Philips Platinum 2R lamp in an Osram HRI 132 W
lamp model. Do not install an Osram HRI 132 W lamp in a Philips Platinum 2R
lamp model. If you install the wrong lamp in a fixture you may cause damage
or experience problems that are not covered by the product warranty.
Important!
Replace the lamp before it reaches the end of its specified
lifetime, or the lamp may explode in the fixture and cause damage that is not
covered by the product warranty. Lamp lifetimes are different for the two
different lamp models. Note the lamp lifetime specified for your model under
’Lamp’ on page 45 and do not exceed the number of hours of use specified
for the lamp.
Replacing the lamp
The lamp must be perfectly clean. Do not touch the lamp’s glass bulb with
bare hands. If this happens, clean the lamp with an alcohol wipe and dry it
with a clean, lint-free cloth.
To replace the lamp:
1. Identify which lamp model fixture you have by checking the serial number
label as described on the previous page. Obtain the correct lamp for your
product.
2. If the fixture has been in use, power the lamp off but leave the fixture
powered on for at least 10 minutes so that the cooling fans cool the lamp.
Disconnect the fixture from power and allow it to cool for 60 minutes.
3. Put on safety glasses and gloves.
4. See illustration on right. Loosen the screws
in the top head cover (arrowed) using a
Phillips screwdriver and remove the cover.
Loosen the corresponding screws in the
bottom head cover and remove that cover
also.
