II.3 PARTIALISATION OF COMPRESSORS IN
QUADRO AND TRIO APPLICATION
II.3.1 Compressor partialisation in Quadro
application
The "quadro" application foresees the use of 4 scroll compressors in
parallel on the same circuit.
In order to guarantee proper system operation the microprocessor
follow certain rules regarding compressor start-up/shutdown, listed here
below:
ON/OFF step: Only one compressor on
It is to be considered a transition necessary to reach the minimum
adjustment step allowed for "quadro" application equal to 50% (2
compressors on);
50% Step: Two compressors on.
These compressors must always be next to each other (condition the
microprocessor forces to follow), therefore the possible combination of
compressors on at the same time are the following:
- Compressor C1 + Compressor C2
- Compressor C2 + Compressor C3
- Compressor C3 + Compressor C4
Step 75%: Three compressors on.
These compressors must always be next to each other (condition the
microprocessor forces to follow), therefore the possible combination of
compressors on at the same time are the following:
- Compressor C1 + Compressor C2 + Compressor C3
- Compressor C2 + Compressor C3 + Compressor C4
100% Step: Four compressors on.
Minimum start up and shut-down times and the maximum number of
start-up/hour are also respected.
II.3.2 Compressor partialisation in Trio
application
The "trio" application foresees the use of 3 scroll compressors in
parallel on the same circuit.
There are no particular rules foreseen regarding the start-up/shutdown
logic of compressors, with the exception of respecting minimum start-up
and shut-down times and maximum number of start-ups/hour.
II.3.3 Compressor partialisation in Tandem
application
The "tandem" application foresees the use of 2 scroll compressors in
parallel on the same circuit.
There are no particular rules foreseen regarding the start-up/shutdown
logic of compressors, with the exception of respecting minimum start-up
and shut-down times and maximum number of start-ups/hour.

TRANSPORT - HANDLING AND STORAGE

DANGER!
The unit must be transported and handled by
skilled personnel trained to carry out this type of
work.

IMPORTANT!

Be careful to prevent damage by accidental
collision.
II.4.1.1 Packaging components
DANGER!
Do not open or tamper with the packaging before
installation. Do not leave the packaging within
reach of children.
SAFEGUARD THE ENVIRONMENT!
Dispose of the packaging materials in compliance
with the national or local legislation in force in your
country.
Each unit is supplied complete with:
 User instructions;
 Wiring diagram;
 List of authorised service centres;
 Warranty document;
 Safety valve certificates;
 Use and maintenance manual for the pumps, fans and safety valves.
II.4.1.2 Lifting and Handling
ATTENTION!
The unit was not designed to be lifted with a forklift
truck.
DANGER!
Movement of the unit must be performed with care,
in order to avoid damage to the external structure
and to the internal mechanical and electrical
components.
Also make sure that there are no obstacles or
people blocking the route, to avoid the danger of
collision or crushing. Make sure that there is no
possibility of the lifting-gear overturning.
Once its suitability has been ensured (capacity and wear conditions),
pass the belts through the passages on the unit base, pull the straps
tight, checking that they remain properly attached to the lifting-hook; lift
the unit a few centimetres, then, only after checking the stability of the
load, carefully carry the unit to the installation site. Lower the unit
carefully and fix it into place. Be careful not to interpose body parts one
handling in order to eliminate any possible risk of crushing or any other
injury if the load drops or shifts suddenly. Use straps/chains of
appropriate length so as to guarantee stable lifting movements. During
lifting and movement operations ensure the unit always remains in
horizontal position.
II.4.1.3 Storage conditions
The units cannot be stacked. The temperature limits for storage are -9 ÷
50°C.
