7.5 Connections
Use the recommended connection (see Fig. 20) unless
specified otherwise. The water supply must be at the
bottom of the water battery - the return must be on
the top.
Place the adjustment valve as close to the unit as
possible. (Please note that many valve motors can go
in both directions and this can be set on the motor.
Set it so that the valve opens on an increasing 0-10 V
signal.)
Before connecting the water battery, it
is necessary to check that the inspection
doors are accessible and there is space
enough to change the water battery.
If you use a water battery that has not had glycol
(or another antifreeze) added, the unit should be in
a heated room on account of the risk of frost in the
battery. Install air dampers with spring-loaded return
for outdoor air. Place the unit close to a gully to avoid
damage caused by any water leaks.
