Operating safety instructions
Carefully read the safety instructions before using any LTG
fan coil unit. Always follow the safety instructions!
The units meet any pertinent safety standards.
The installation and maintenance of air
conditioning units may be dangerous be
cause of high pressures and electrical com
ponents being alive. Therefore, the installa
tion, maintenance, and repair must be per
formed by qualified and trained staff only.
In particular electrical connections are to be provided,
removed, or modified by authorized persons only ob
serving all relevant safety instructions.
Safety instructions in the technical documentation and
on unit labels must be followed at all times.
Do not open the unit for cleaning, maintenance, or repair
and do not remove covers and casings (air diffuser) un
less all conducting lines have been completely discon
nected. Do not connect or remove the plug-in connector
when under tension.
Any work regarding the electrical equipment is to be
performed by skilled and trained staff only. Connections
to the main power supply and the safety earth terminal
must be executed exactly as described in the wiring dia
gram.
Electrical operation of the unit in a partly disassembled
condition or of individual components is not permitted
since earth terminals might be interrupted.
During continuous opera
tion the motor may reach
temperatures
of
up
to
149 °F. If necessary, allow
the motor to cool off or wear
gloves.
In the heating mode a water
temperature of up to 176 °F
may be achieved. Water-
carrying parts may be hot
so do not touch with your
bare hands to avoid burns.
Be careful when performing
work on the heat exchang
ers. Blades and housing
parts
are
sharp-edged.
Wear gloves during work
and handling.
