Jaspi Inverter Nordic-12, Руководство по установке

Страница: 32 / 68

Preparations
■
Check that the pipe system is prepared.
■
Check the pipe system for leaks.
■
Check that the electrical installation is prepared.
■
Check that the electrical supply is connected so that
the compressor heater (EB10) can start warming up
the compressor, if necessary.
■
The compressor heater (EB10) must have been active
for at least 3 hours before compressor operation can
be initiated. This is done by connecting control voltage.
JÄSPI Inverter Nordic permits compressor start after
the compressor has been warmed up. This can take
up to 3 hours.
Balance temperature
The balance temperature is the outdoor temperature
when the heat pump’s stated output is equal to the
building’s output requirement. This means that the heat
pump covers the whole building’s output requirement
down to this temperature.
Filling and venting
Filling and venting the heating medium system.
1. Fill the heating medium system to the necessary
pressure.
2. Vent the system using the venting nipple on the flex
hose (enclosed) and possibly the circulation pump.

Start-up and inspection
1. Communication cable, terminal block (X22:1-4) must
be connected.
2. If cooling operation with JÄSPI Inverter Nordic is
wanted, DIP switch S1 position 4 must be changed
according to the description below on page 24.
3. Turn the isolator switch on.
4. Ensure that the JÄSPI Inverter Nordic is connected
to the power source.
5. Check that fuse (FC1) is on.
6. Reinstall the removed panels and cover.
7. After the power to JÄSPI Inverter Nordic has been
switched on and there is a compressor demand from
the indoor module/control module, the compressor
starts once it has warmed up, after max 180 minutes.
The length of this time delay depends on whether
the compressor has been warmed up previously. See
chapter Preparations on page 32.
8. Adjust the charge flow according to size. Also see
section “Adjustment, charge flow” on page 33.
9. Adjust menu settings via the indoor module/control
module as necessary.
10. Fill in the commissioning report in the user manual.
11. Remove the protective film from the cover on
JÄSPI Inverter Nordic.
NOTE
The external control must be taken into consid-
eration when connecting.
Readjusting, heating medium
side
Air is initially released from the hot water and venting
may be necessary. If bubbling sounds can be heard from
the heat pump, the circulation pump and radiators the
entire system will require further venting. When the
system is stable (correct pressure and all air eliminated)
the automatic heating control system can be set as re-
quired.
