Preparations
■
Check that the signal cable between AMS 10 and
HBS 05 is connected.
■
Check that the service valves (QM35 and QM36) are
open.
■
Before commissioning, check that the charge circuit
and climate system are filled and well vented.
■
Check the pipe system for leaks.
■
Check that AMS 10 and HBS 05 are electrically connec-
ted.
Filling the climate system
1.
The heating medium system is filled with water to
the required pressure.
2.
Vent the system using the installed venting nipple
and any circulation pump.
Venting the climate system
See chapter "Commissioning and adjustment" in the In-
staller Manual for the indoor module / control module.
Compressor heater
AMS 10 is equipped with a compressor heater (CH) that
heats the compressor before start-up and when the
compressor is cold. (Does not apply to AMS 10-6.)
Start-up and inspection
NOTE
The compressor heater (CH) must have been
operational for at least 6 - 8 hours before the
compressor start can be initiated. This is done
by switching on the control voltage and discon-
necting the communication cable.
1.
AMS 10 must be addressed if it is to have an address
other than 1. See chapter Addressing via cascade
connection on page 28.
2.
The communication cable on the terminal block
(AA23-X4) must not be connected.
3.
Turn the isolator switch on.
4.
Ensure that the AMS 10 is connected to the power
source.
5.
After 6 – 8 hours the communication cable is connec-
ted on the terminal block (AA23-X4).
6.
Start any indoor module / control module. Follow
the instructions for "Start-up and inspection" in the
Installer Manual for the indoor module / control
module.
The heat pump starts 30 minutes after the outdoor
module is powered and the communication cable is
connected, if necessary.
If scheduled silent operation is required, it must be
scheduled in the indoor module or control module.
NOTE
Do not start AMS 10 at outdoor air temperat-
ures of -20 C or less.
Caution
Silent mode should only be scheduled period-
ically because the maximum output is limited
to approx. the nominal values.
Caution
Do not start any electrical work until at least
two minutes after cutting the power.
Inspection of the installation
Current regulations require the climate unit to be inspec-
ted before it is commissioned. The inspection must be
carried out by a suitably qualified person and must be
documented. Use the checklist on page 8. The above
applies to closed climate systems.
Do not replace any part of the system NIBE SPLIT HBS 05
without carrying out new checks.
