HYDRAULIC SYSTEM DATA

WATER FLOW AND AVAILABLE STATIC PRESSURE (Factory supplied; standard water pump and filter).

NOTE: The flow data indicated in table are between a minimum and a maximum water flow
With the option twin pump kit, the available static pressure will decrease 5% from the data shown above
Unit conversion:
Pressure 1KPa = 1/9,8 m.c.a. = 0,01 bar
1 bar = 10 m.c.a. = 100 kPa
MINIMUM WATER FLOW
The installation must never operate with less than the minimum water flow (see table above), this will cause:
i. - Freezing the water heat exchanger.
ii. - Contamination of the heat exchanger.
MAXIMUM WATER FLOW
See maximum water flow, (see table above). Always assure the minimum ∆T to the exchanger of 3ºC.
MAXIMUM WATER VOLUME IN THE INSTALLATION
The units with Hydronic or Hydraulic module include a expansion vessel.
The table below details the maximum water volume in the system.

Water + 10% gyt
Water + 20% gyt
Water + 30% gyt
Water + 35% gyt
If the water volume in the system is greater than that detailed in the table it will be necessary to add additional expansion vessel(s).
The system design must allow for water expansion and contraction.
