Procedure of the installation of the system
The following basic procedures must be observed for installation of the system:
1. Read the specifications of the system and make sure that you understood
them.
2. Make sure that the installation site meets the requirements.
3. Check the tools and equipment, especially concerning the suitability with
R-290.
4. Accomplish the proper connection of the system.
5. Check the integrity of the system and check all the functions.
6. Hand over the end user manual to the client and instruct the operator
about the basic functions of the system.
7. Fill in and sign the commissioning report (Start-up data sheet) provided on
page 70 of this manual.
Installation of the indoor unit
After choosing a reliable installation site and a controlled check of the tools for
mounting the system, start mounting the indoor unit.
The Mounting Plate
Install the mounting plate where the indoor unit will be placed.
Place the mounting plate horizontally, ensuring there is still a slight tilt in order to
make sure that condensate will run out unimpeded from the indoor unit.
Drill the holes and then fix the mounting plate by using dowels and screws. Pay
attention to the way the wall is constructed at the chosen installation site. Make
sure that the chosen screws and dowels are able to carry the weight of the in-
door unit.
During drilling be aware of the possibility of existing supply piping such as water
pipes or electrical wires.
Make sure not to tighten the screws directly. Align the installation plate with a
slight tilt only then tighten the screws. Be mindful of a strong and even contact
with the installation plate to the wall. In doing so, vibrations and sound transmis-
sion is avoided.
Furthermore, pay attention to equal the weight distribution of the indoor unit to
all screws.
