Installing the ducting (see
CAUTION
▪
Make sure the installation of the duct does NOT exceed the setting range of the
external static pressure for the unit. Refer to the technical datasheet of your
model for the setting range.
▪
Make sure to install the canvas duct so vibrations are NOT transmitted to the
duct or ceiling. Use a sound-absorbing material (insulation material) for the lining
of the duct and apply vibration insulation rubber to the hanging bolts.
▪
When welding, make sure NOT to spatter onto the drain pan or the air filter.
▪
If the metal duct passes through a metal lath, wire lath or metal plate of the
wooden structure, separate the duct and wall electrically.
▪
Install the outlet grille in a position where the airflow will not come into direct
contact with people.
▪
Do NOT use booster fans in the duct. Use the function to adjust the fan rate
setting automatically (see
Refrigerant piping installation (see
CAUTION
Do NOT reuse piping from previous installations.
CAUTION
Install the refrigerant piping or components in a position where they are unlikely to
be exposed to any substance which may corrode components containing refrigerant,
unless the components are constructed of materials that are inherently resistant to
corrosion or are suitably protected against corrosion.
WARNING
▪
Use K65 piping for high-pressure applications with a working pressure of 120 bar.
▪
Use K65 unions and fittings approved for a working pressure of 120 bar.
▪
Only brazing is allowed for connection of pipes. No other types of connections are
allowed.
▪
Expanding of pipes is not allowed.
Electrical installation (see
WARNING
▪
If the power supply has a missing or wrong N-phase, equipment might break
down.
▪
Establish proper earthing. Do NOT earth the unit to a utility pipe, surge absorber,
or telephone earth. Incomplete earthing may cause electrical shock.
▪
Install the required fuses or circuit breakers.
▪
Secure the electrical wiring with cable ties so that the cables do NOT come into
contact with sharp edges or piping, particularly on the high-pressure side.
▪
Do NOT use taped wires, stranded conductor wires, extension cords, or
connections from a star system. They can cause overheating, electrical shock or
fire.
