Jaspi Inverter Nordic 8, Руководство по установке

Страница: 20 / 68

General
Pipe installation must be carried out in accordance with
current norms and directives.
The pipe dimension should not be less than the recom-
mended pipe diameter according to the table. However,
each system must be dimensioned individually to man-
age the recommended system flows.
Minimum system flows
The installation must be dimensioned to manage at least
the minimum defrosting flow at 100% pump operation,
see table.

NOTE
An undersized system can result in damage to
the product and lead to malfunctions.
JÄSPI Inverter Nordic can only operate up to a return
temperature of about 55 °C and an outgoing temperat-
ure of about 65 °C from the heat pump.
JÄSPI Inverter Nordic is not equipped with shut-off valves
on the heating medium side, rather these must be in-
stalled to facilitate any future servicing. The return tem-
perature is limited by the return line sensor.
Water volumes
Depending on the size of your JÄSPI Inverter Nordic, an
available water volume is required to prevent short op-
erating times and to enable defrosting. For the optimum
operation of JÄSPI Inverter Nordic, a minimum available
water volume of 10 litres multiplied by the size number
is recommended. E.g. JÄSPI Inverter Nordic-12: 10 litres
x 12 = 120 litres. This applies individually to heating and
cooling systems.
NOTE
The pipe installation must be flushed out be-
fore the heat pump is connected so debris
cannot damage component parts.

non-return valve
Installations with only one heat pump: a non-return
valve is only required in those cases where the place-
ment of the products in relation to each other can
cause self-circulation.
Cascade installations: each heat pump must be fitted
with a non-return valve.
