7.5 Completing the installation
Perform the following working steps:
1.
Tighten all cable screw connections to guarantee the IP protection
class of the installation.
2.
Check all connections for leak-tightness (see section 9 „Commis-
sioning“ on page 20).
3.
Touch up damaged paint.
i
All exposed bright metal surfaces must be painted as the
atmosphere in chlorine gas rooms is highly corrosive. A
suitable paint is e.g. 2-Component epoxy resin lacquer
RAL 1003 (yellow). Paint must only be applied after a
successful leak test has been completed.
ü
Installation completed.
