Important information to the installer / Checklist
Important information to the installer!
The Installer section of this manual gives you all the information necessary
to install the heat pumps Optima 1000 and 1300. The section is divided into
several parts. The order of these is based on the recommended installation
sequence from IVT. Use the supplied checklist during installation.
Before you start the installation of the Optima heat pump we would
like to bring the following to your attention:
The heat pump may be temporarily tilted with the compressor
downwards. However, never lay the heat pump down.
Before the heat pump is commissioned, the heat transfer systems
including the heat pump must be filled and vented.
Check that plumbing connections are intact and have not shaken loose
during transport.
The heat pump is equipped with the control unit Rego 603. When the
heat pump is commissioned the control unit must be set for the selected
operating mode. Read more about the settings in Commissioning the heat
pump.
The control unit Rego 603 measures the phase sequence and gives an
alarm if the power supply has been connected incorrectly. The correct
phase sequence is necessary for the fan to run in the right direction.
If Optima is used in a system with a fan-assisted radiator, the water
volume in the system is very small. During defrosting the heat pump
takes some of its energy from the heating system. This means the heating
system will cool down. It is therefore ver y important that the fans in the
fan-assisted radiators run during defrosting alternatively are connected to
a cylinder of approximately 100 litres.
Wiring should be kept as short as possible to protect the system from
downtime, for example during a thunderstorm.
The heat pump installation must follow applicable regulations.
Checklist
Each installation of the Optima heat pump is unique. However, the following
checklist will give you a general description of how the installation should be
carried out.
1. Position the heat pump on a solid base.
2. Install incoming and outgoing pipes for the hot side.
3. Install the drainage pipe.
4. Install the particle filter, connect to an external additional heat supply
(electric cassette or electric/oil-fired boiler) and possible hot water
heater.
Only qualifi ed installers may carry
out the installation. The installer must
follow to applicable regulations and
recommendations from IVT.
!
For reasons of safety the main power
supply must be disconnected before
working on the heat pump.
During defrosting, the air from the
fan-assisted radiator may seem cold.
This is perfectly normal.
