Connect water pipes
The connections for the water section are at the bottom of the unit:
1� Incoming cold circulating water connection (RET)
2� Outgoing hot circulating water connection (SUP)
Remove the protective caps and connect the water circuit to the 22 mm diameter water pipes with compression fittings� Use a
500 mm long hose here in all cases in order to cut down vibration transfer�

SUP RET
Fit an expansion vessel on the cold side of the water section in order to accommodate rising pressure in the system� Its size will
depend on the water capacity of the system�

Connecting air ducts
Choosing air ducts
Flow rate and maximum air velocity are defining factors in
choosing the right ducting in order to avoid generating any extra
intrusive noise and pressure drop�
ETA duct diameter
Follow the guidelines for maximum airflows per duct diameter,
based on noise generation and pressure drop:
Ø 100
Ø 125
Ø 150
Ø 180

Take care to ensure that total back pressure is as low as possi-
ble (target ≤ 150 Pa) and air velocity in each duct is < 3 m/s and
< 1.5 m/s in branch take-offs�
ODA and EHA duct diameter
Use rigid thermally insulated ducting for ODA and EHA� A diame-
ter of 200 mm is recommended for an acoustically sensitive / long
installation� Never use flexible connections� Avoid unnecessary
bends in this duct�
