this section.
For normal requirements, the water used for the washer must have the
following minimum quality:
Appearance
pH value
Total salt content
Electric conductivity
Calcium-ion content
Carbonate hardness
Carbonate hardness when using
hardness stabilising agents
Chloride content
Sulphate content

Germination index
For connection of the washer to the public water mains, the regulations of
DIN 1988 apply.
A drain trap must be connected to the condensate drain section of the
cooling trough and the KGX/KGXD trough to ensure drainage of the
condensate.
It should, however, be noted that one drain trap must be connected to each
condensate drain section.
It is not permissible to join several drain sections onto a common drain trap.
WOLF supplies the drain trap as an accessory. The required drain trap
height must, in this case, be determined on site.
If the drain trap is provided by the customer, the drain trap height must be
determined according to the adjacent illustration.
The effective drain trap height H (mm) must exceed the max. vacuum or
overpressure (mm WC) in the air-conditioning unit (1 mm WC = 10 Pa).
The height differential between the outlet of the unit and the drain trap
overflow should also be H (mm).
Always ensure adequate foundation height to enable the installation of the
drain trap.
The drain pipe of the drain trap may not be directly connected to the waste
water system but must drain freely (see illustration). In case of longer drain
pipes, the pipes must be ventilated to prevent condensate accumulation in
the pipe.
Before initial start-up of the unit and after long periods of inactivity, the drain
trap must be filled with water!
