Installation
Prior to the installation:
• Check scale collector tank, O-ring, snap ring and strainer insert for damages and replace defective
components if necessary. We recommend to replace the sealings of the scale collector tank with
each maintenance. For that purpose a maintenance kit is available (see parts list).
• Remove any dirt inside the retaining ring on the bottom of the unit and clean it with a clean rag.
1. Insert the strainer insert into the corresponding receptacle inside the scale collector tank and press
it down until it locks. Then, attach O-ring and Snap ring to the locking ring of the scale collector tank.
2. Align locking ring to the grooves of inside retaining ring. From the bottom push the scale collector
tank into the retaining ring until it comes to a stop (1.). Turn locking ring clockwise until it comes to
a stop (2.), then, push locking ring upwards until it comes to a stop (3.) and turn it counterclockwise
until it locks inside the spring-actuated lock (4.).
3. Close drain valve on the bottom of the scale collector tank.
Note: On units equipped with the optional drain valve for the scale collector tank, connect drain hose
to the drain valve, then open drain valve.
