The above diagram applies during primary flow (charge
flow) at 1000 l/h.
Coil
Maximum primary flow 1650 l/h. Circulation pump
required.
The pressure drop in the coil is determined according to
diagram 2 "Pressure drop in coil".
The primary temperature for the coil must not exceed
95°C.
To bleed the coil, fill the coil with a large amount of
water.
