6. Maintenance
This completes the lamp replacement.
Go on to the cooling pump replacement.
To replace the cooling pump:
6. Remove the cooling pump.
(1) Loosen the cooling pump cover screw until the screwdriver goes into a freewheeling condition.
- The cooling pump cover screw is not removable.
5. Reattach the lamp cover.
Tighten the lamp cover screw.
Be sure to tighten the screw.
4. Push the part as shown on the drawing and insert a new lamp housing until it is plugged into the socket.
CAUTION
Do not use a lamp other than the NEC replacement lamp NP03LP (NP60) or NP02LP (NP50/NP40).
Order this from your NEC dealer.
Secure it in place with the two screws.
NOTE: Tighten the two screws alternately until both screws are completely tightened. Failure to do this can result in air leak
from the cooling pump, causing the pump error. ( page
