regulations for the safety of the environment.
The oil change procedure are described in the corresponding Operating
Instructions GA 01.601 and these must be foolowed closely.
As already stated in Chapter 9.1.1 only Arctic oil must be used for the Tri-
vac D 2,5E pump in the PhoeniXL.
After completion of all maintenance work the cover of the mechanical sec-
tion must engage properly in the openings at the bottom.
9.1.5 Cleaning
The housing of the PhoeniXL is made of painted plastic parts. Thus for the
purpose of cleaning, only such agents should be used which are generally
also used for other painted or plasctic surfaces (mild household cleaning
agents, for example). Normally a moistened peace of cloth will do. Never
use any solvents which are capable of dissolving paint (like acetone, toluol,
etc.).
A soft brush or a vacuum cleaner is recommended for cleaning the ventila-
tion slits.
9.1.6 Exchanging the fuses
Caution Before exchanging the fuses you must disconnect the mains
cord.
1. Switch the PhoeniXL off.
2. Pull the mains cord off the PhoeniXL.
3. Use a screwdriver to fold out the lid of the mains socket from the right
(the mains switch is not affected by this).
4. The fuses can be removed by pulling the drawers out which are marked
by the arrows. When reinsering these make sur that the arrows point
downwards.
5. In any cases two fuses of the same rating must be inserted. The requi-
red mains fuses are: T 10A slow blow (20x5mm dia.) for 100V...230V.
6. After having exchanged the fuse(s) press the lid of the mains socket
firmly back on.
7. Insert the mains cord into the PhoeniXL and switch the instrument on.
Beside these mains fuses several internal circuits are fused separately.
These fuses are listed in the following table. See also Fig 37.
In order to exchange these fuses you must proceed as follows:
1. Switch the PhoeniXL off
2. Pull the mains cord on the PhoeniXL
3. Remove the cover for the mechanical and electronics section according
to Chapter 9.1.2 .
