Filling the heating system
Monitoring the screw joints
Due to vibration and thermal expansion, all screw
joints must be inspected and tightened prior to
commissioning.
Permissible media
•
Heating water according to ÖNORM H 5195-1.
The permissible water hardness for the heating
water can be determined from the table in Section
.
The requirements of ÖNORM H 5195-1 apply
as minimum requirements for the heating
water. If stricter country-specific regulations exist,
they are to be heeded.
•
Water/glycol mixtures with a glycol ratio of
minimum 20% and maximum of 30%
Glycol has a higher viscosity than water.
When admixing glycol, the pumping data
must be corrected according to the mixing ratio.
Proper use includes compliance with these instruc-
tions as well as the information and labelling on the
pump.
Filling and bleeding the heating system
Fill the heating system and take note of the maximum
water pressure. Carefully bleed the heating system
after filling.
