Installing on VPB 200
Caution
For connection of VPB 200 together with F750
docking kit DEW 40 is used.
1.
Remove the service cover from VPB 200.
2.
Remove the top panel from VPB 200 (installed with
6 screws).
3.
Install DEW 40 according to the instructions in the
installation manual. The pipes in VPB 200 can be
adjusted/replaced in such a way that SAM 40 can
easily be installed above VPB 200.
4.
Install SAM 40 from the top and slide into position.
5.
Secure SAM 40 with the 2 screws supplied.
6.
Connect heating medium and ventilation pipes.
7.
Reinstall the service cover on VPB 200.
Heating medium side
A water borne climate system with a volume of at least
20 litres of circulating water must be present for install-
ation of SAM 40 to be possible. For the correct function
of SAM 40 the total volume of the climate system (ex-
cluding the internal volume in F750) must exceed 40
litres of circulating water. This means that, if the volume
of the climate system does not exceed 40 litres of circu-
lating water, installation of volume vessel (NIBE UKV)
is necessary.
Dimensioning the system
1.
Work from the water temperature at DUT (DVUT).
2.
Work from the current supply air flow.
3.
Work from the desired supply air temperature,
then calculate the output that SAM 40 must give
at DUT.
4.
Determine the water flow across SAM 40 from the
correct output diagram. NOTE! For supply temper-
atures that are not in one of the diagrams, an es-
timate (linear interpolation) can be carried out.
5.
Work from the projected pressure drop (at the
projected flow) in the water borne system, climate
system 1.
6.
Check in the pressure drop diagram that the
working point is inside the grey working area.
7.
Check that the pump capacity from F750 is suffi-
cient for both the heating system and SAM 40.
