GENERALITIES F-H
The IDRA-RSC series is made of 6 sizes of air cooled water chillers (F version) and heat pumps (H version) with radial fans covering a range of capa-
cities from 5 to 17 kW.
They have been designed to operate at extremely low noise levels and to offer high reliability, efficiency and easy maintenance. All the units undergo a
very strict and detailed factory test before delivery. The structure of the units allows also for an outdoor installation. The refrigeration circuit is charged
with R407C refrigerant.
The high reliability of the components employed, as well as the strict tests which all units must undergo, grant a very high quality standard.
AVAILABLE VERSIONS:
F: air cooled water chillers with radial fans.
H: air cooled heat pumps with radial fans.

SAFETY
The FAST chiller IDRA-RSC series have been designed in order to minimize all the possible risks for the operators safety.
Please, read carefully the following instruction in order to be aware of the possible dangerous situations while operating
with the unit.
ACCESS TO THE UNIT
Only authorized personnel are entitled to access to unit. The operators must operate with the unit using adequate safety
devices and gear.
RESIDUAL RISKS
The unit installation, start-up, switch-off, maintenance must respect the indications given in the product technical docu-
mentation and, in any case, preventing any possible dangerous situation. Please, consider the following possibly hazar-
dous situations.
Component Residual risk possible cause precautions

RECEIPT AND STORAGE
On receipt of the goods, verify they have not been damaged and they conform to what indicated in the transport documen-
ts. Damages or incomplete supplies must be notified immediately .
Store the units in suitable warehouses (temperatures from -20°C to max. +55°C).
HANDLING
The units can be handled both with fork lifters or cranes. When handling the unit, pay special attention not to damage the
condensing coil. Before moving the units, check their dimensions reported in the present manual. It is recommended to
handle the units still packaged.
Lifting with fork lifter
Lift the unit with a fork lifter of adequate loading capacity, verify that the forks lenght is at least 1200 mm.
Place the forks following the instructions shown in the figure below. Be sure the unit is in perfect stable balance.

POSITIONING
Install the unit respecting the clerances indicated in the dimensional drawings. Lay the unit on an even surface, robust
enough to bear its weight.
Antivibrations dampers
Rubber antivibration dampers are supplied as an option. Fitted to the holes in the basement, they prevent vibrations tran-
smission.
INSTALLATION
Hydraulic connections: unit with incorporated hydraulic kit
We suggest to make the hydraulic connection of the unit as shown in the figure below.
A water filter, to be installed on the inlet pipe, is to be considered as mandatory. The warranty will no longer be
valid if no filter is installed on the inlet pipe.
The hydraulic kit includes: circulation pump, storage tank, air relief valve, differential pressure switch, safety valve (only
on heat pump versions).
M = pressure gauge RC = discharge shut-off valve RS = discharge shut-off valve
VS = air relief valve FA = water filter GA = antivibration pipe
