Water quality
General guidelines for required water quality are provided as a part of this manual. Having
a proper water treatment and maintenance program in place is essential for all closed and
open loop hydronic systems. Local codes and requirements of various other components used
in specific hydronic systems might mandate some changes to recommended values. It is our
strong recommendation that a professional water treatment company is employed for initial
commissioning and ongoing annual maintenance of water loop system.
CAUTION
It is strongly recommended that a professional water treatment company is used to perform ongoing
maintenance of the water loop system, including chemical analysis and if necessary flushing. The water
loop testing should be performed at intervals recommended by the professional water treatment
consultant. It is up to the customer to carry out adequate water loop maintenance over the lifespan of
the units, otherwise damage to the units may occur.
