where it should be set up.

6. PIPING INSTALLATION

NOTE! To prevent leaks ensure that there are no
!
stresses in the connecting pipes!
NOTE! It is important that the heating system is
!
completely bled after installation.
NOTE! Bleed valves must be installed where
!
necessary.
Ensure that the piping installation follows the dimension and
l
connection diagrams in Section 2 Heat pump information.
Piping installation must be carried out in accordance with
l
applicable local rules and regulations. The hot water tank must
be equipped with an approved safety valve (supplied).
The position lists show the components and parts included in the
l
delivery in italics.
Selecting the heating system
The heat pump is set to VL system on delivery, that is with an
integrated electrical auxiliary heater and an exchange valve after
the auxiliary heater.
What determines which of the three systems VL, VLD should be
used is, among other things, how any auxiliary heater is used for
hot water production, and which model of heat pump is used.

6.1. vL SYSTEM

In a VL system the heat pump can produce both heating and hot
water with the compressor and the integrated auxiliary heater.
Production of heating and hot water cannot occur at the same time
because the exchange valve for heating/hot water is positioned
after the auxiliary heater.
The integrated auxiliary heater carries out peak heating charging
(legionella function) in those operating modes that permit auxiliary
heat.
