Installation
Before filling the circuit, it is important to
check that it is free from any foreign matter,
sand, gravels, rust, welding deposits, waste
and other materials that may damage the
evaporator.
When cleaning the lines, it is recommended to cre-
ate a circuit by-pass. It is important to mount a filter-
ing medium (30 mesh) upstream of the chiller.
If necessary, the water required to fill the
circuit must be treated to obtain the request-
ed PH.
4.4 Hydraulic connection
The water inlet/outlet fittings shall conform to the in-
structions provided by the plates affixed neat the
connection points.
4.5 Draining the defrosting
waste water
(for heat pump unit only)
When heat pump units work in heating mode, dur-
ing defrosting cycles, they may discharge water from
the base. This is why the units should be installed at
least 200 mm above the floor level, so as to allow
the free drainage of waste water, without the risk of
producing ice banks.
The heat pump units must be installed in positions
where the defrosting water cannot create any dam-
age.
4.6 Power supply
Before carrying out any operations on the
electrical system, make sure that the unit is
deenergised.
It is important that the appliance is ground-
ed.
