Edition 01/2014
contrAA 600
This pushes the lamp housing forward on the two guiding pins and the electric plug
connection (not visible) is removed.
4.
Pull on the handle of the lamp housing with one hand and hold the housing at the bot-
tom with the other hand. Pull the housing to the front and off of the guiding pins.
Note:
Keep a firm grip on the lamp housing when pulling it off the guiding pins. The
housing is heavy!
Do not touch the lamp window!
5.
Put the removed lamp housing to the side.
6.
Stick the new lamp housing on the guiding pins and push it toward the back.
Note:
Do not touch the lamp window!
7.
Screw in the attachment screw of the lamp housing completely using a hexagon socket
wrench and tighten the screw.
This presses the lamp housing to the back on the two guiding pins and into the electrical
multipole plug connection.
Note:
It must be possible to screw in the lamp housing without noticeable resistance!
Do not use force!
8.
Connect the cooling water hoses to the bottom of the lamp housing.
Press the plug connectors of the hoses into their counterparts at the lamp housing (left
hose - left inlet; right hose - right inlet) and push them in as far as they will go.
Note:
There should be an audible click when the hoses are plugged in and the interlock
in the connection piece of the lamp housing should pop out.
9.
Switch on the contrAA 600.
10. Make sure that circulation pump works and cooling water flows back to the stabilization
vessel.
Note:
If the pump is running and no cooling water flows back, one (or both) plug con-
nector/s is not adjusted correctly. In this case disconnect the couplings again and press
them in properly.
11. Check the filling level in the stabilization vessel of the circulating pump and fill with tap
water if required (
→
Section "Check the cooling water level" p. 59).
The fill level will decrease slightly after the lamp has been installed. This is due to the
heat sink of the lamp filling with cooling water. The displaced air is released via the sta-
bilization vessel after a few seconds.
Tighten the cover of the stabilization vessel by hand only.
12. Mop up any drops of water.
13. Close the lamp chamber door.
