5 If the outdoor unit is installed above the indoor unit, cover the
stop valves (A,B see above) with sealing material to prevent
condensed water on the stop valves from moving to the indoor
unit.
NOTICE
Any exposed piping might cause condensation.
6 Reattach the service cover and the piping intake plate.
7 Seal all gaps (example: a) to prevent snow and small animals
from entering the system.

NOTICE
Do not block the air vents. This could affect air circulation
inside the unit.
WARNING
Provide adequate measures to prevent that the unit can be
used as a shelter by small animals. Small animals that
make contact with electrical parts can cause malfunctions,
smoke or fire.
NOTICE
Make sure to open the stop valves after installing the
refrigerant piping and performing vacuum drying. Running
the system with the stop valves closed may break the
compressor.
