Страница: 28 / 68

Preparations
Caution
Check the miniature circuit-breaker (FC1). It
could have tripped during transport.
NOTE
Do not start JÄSPI Inverter Nordic if there is a
risk that the water in the system has frozen.
Compressor heater
JÄSPI Inverter Nordic is equipped with two compressor
heaters that heat the compressor before start-up and
when the compressor is cold.
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.
NOTE
The compressor heater must have been active
for approx. 3 hours before the first start, see
section “Start-up and inspection”.
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
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 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 in section "Cooling".
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
the instructions in section "Preparations".
8. Adjust the charge flow according to size. Also see
section “Adjustment, charge flow”.
9. Adjust menu settings via the indoor module/control
module as necessary.
10. Fill in "Inspection of the installation", in section "Im-
portant information".
11. Remove the protective film from the cover on
JÄSPI Inverter Nordic.
NOTE
The live external control must be taken into
consideration when connecting.
Post adjustment and venting
Air is initially released from the hot water and venting
may be necessary. If bubbling sounds can be heard from
the heat pump, the charge pump or radiators, the entire
system requires further venting. When the system has
stabilised (correct pressure and all air eliminated), the
automatic heating control system can be set as required.
