1. SAFETY PRECAUTIONS
1.1.
WARNINGS FOR INSTALLERS
The air conditioner may only be installed, plumbed in and wired by persons who
-
meet the technical and professional requirements to install and maintain such
systems.
This air conditioner must be installed in accordance with national plant engineering
-
regulations. Pay particular attention to the aspects concerning safety and the proper
connection of electrical cables. Errors while connecting cables may lead to fires.
-
Connect the air conditioner to the mains or to a power socket with a suitable voltage
and frequency. A power supply with an incorrect voltage and frequency may result in
damage to the unit with a consequent fire risk. The voltage must be stable and
without excessive fluctuations.
-
Install the condensation drainage piping so as to ensure that the condensation is
removed correctly. Also adopt the most appropriate solutions to prevent heat loss
and the resulting formation of condensation. An incorrect piping configuration may
lead to water leakage and wet furniture and objects in the indoor environment. The
air conditioner must be earthed. Incomplete or poorly set-up earth may cause
electric shocks.
Do not connect the earth cable to other pipes, water pipes, lightning rods or the
-
telephone earth wire.
Install an Omnipolar switch (with a minimum contact distance of at least 3 mm on all
-
terminals on the power supply circuit to prevent possible discharge to ground and
short circuits.
-
The Omnipolar switch and any socket must be installed in an easily accessible
location.
-
Do not remove the power cable while the unit is running or with wet hands. Doing so
risks electric shocks and fires.
-
Use cables that are intact and whose cross-section is appropriate for the load for the
power supply.
-
Do not make joints on the power cable. Use a longer cable if necessary. Joints can
cause overheating or fire.
In the event that the power cable is damaged, it must be replaced. Use a type of
-
cable featured in the manual only.
Install a noise filter if the power supply emits too much noise.
-
Do not leave any cables in direct contact with the refrigerant piping which could
-
reach excessive temperatures.
Do not leave any cables in direct contact with moving parts, such as fans. Make sure
-
the communication cables between the units are connected to the correct terminals.
-
Only replace fuses with ones identical to the original.
lf the filter is very dirty, this will significantly reduce the cooling capacity of the
-
appliance.
-
Tighten the nut to the torque indicated in the device manual. Overtightening can lead
to leakage of refrigerant.
-
Do not install the indoor unit outside. Doing so may result in damage and electrical
losses.
During installation of the indoor unit(s), consider the distribution of air in each indoor
-
unit in the room in order to select the most suitable position and ensure a
temperature as uniform as possible within the environment.
Do not install the indoor unit in a location directly exposed to sunlight.
-
Do not install the unit near liquids and highly flammable gases. Install the unit in
-
locations with the minimum content of dust, smoke, air humidity and corrosive
agents.
