RECAUTIONS FOR INSTALLATION
All instructions described in this manual shall be carried out by a
licensed installer.
Install the unit according to the instructions in the included
documentation and the manuals of the additional equipment (e.g.
controller). Improper installation could result in electric shock, short-
circuit, leaks, fire or other damage to the equipment.
Be sure to wear adequate personal protection equipment (protection
gloves, safety glasses) when performing installation, maintenance or
service to the unit.
If not sure of installation procedures or operation of the unit, always
contact your local dealer for advice and information.

REPARE THE INSTALLATION OF THE AIR
TO WATER CHILLER
3.1. Check that you have all optional equipment
3.2. Verify the appropriate installation location
DANGER: ELECTRICAL SHOCK
Switch off all power supply before removing the switch box
cover or before making any connections or touching
electrical parts.
To avoid electric shock, be sure to disconnect the power
supply 1 minute or more before servicing the electrical
parts. Even after 1 minute, always measure the voltage at
the terminals of main circuit capacitors or electrical parts
and, before touching, be sure that those voltages are less
than 50 V DC.
DANGER: HIGH TEMPERATURE
Do not touch the water piping or internal parts during and
immediately after operation. The piping and internal parts
may be hot or cold depending on the working condition of
the unit.
Your hand may get burned or frostbitten if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if
you must touch them, be sure to wear adequate protective
gloves.
CAUTION
For use of units in applications with temperature alarm
settings it is advised to foresee a delay of 10 to 15 minutes
for signalling the alarm in case the alarm temperature is
exceeded. The unit may stop for several minutes during
normal operation for "defrosting of the unit" or when in
"thermostat-stop" operation.
Factory mounted options Descriptions
Hydraulic package (N) N (standard) contains flow switch,
filter, shut-off valves, pressure ports,
drain/fill valve.
Hydraulic package (P) Identical to N plus pump, expansion
vessel, safety valve, pressure gauge.
High static pump (H) Identical to P but allows operation in
applications with high pressure
drops inside the hydraulic system.
Water piping heater tape (—H—) The water piping heater tape warms
up to prevent freezing of water inside
the unit during winter while the unit is
at stand still.
Low temperature cooling (B— —) Allows to cool liquid (water + glycol)
down to –10°C.
