INSTALLATION RECOMMENDATIONS
If possible, position the gascooler preferably above the entry point of the liquid into the liquid receiver, to help the condensate flow
away by gravity (subcritical running).
If the unit is to be mounted on a roof, roof structure has to be strong enough to support total weight of the gascooler without
bending.
AREA OF INSTALLATION
When installing multiple units,a space of 1200mm should be allowed around the condensers to prevent exhaust air recirculation. For
special installation, please contact PROFROID.
For Horizontal condensers frame mounted:
Free space bottom the condenser > 590 mm
For Vertical condensers frame mounted:
Space (Exchanger <-> Wall) height of the heat exchanger
For special installation, please consult us.
REFRIGERATION NETWORK CONNECTION
General information
B
EFORE ANY WORK IS DONE ON THE REFRIGERATION CIRCUIT
,
THE HOLDING CHARGE MUST BE REMOVED
(NITROGEN).
The piping used (copper CuFe2P or stainless steel 304L) must be of refrigeration quality in accordance with PED 2014/68/UE.
All piping must be correctly supported and fixed and should in no case be allowed to restrict the piping of the gascooler.
Connection to discharge
The pipe diameters must be determined in advance to ensure correct oil return and should not be based on the diameters of the
discharge header valves. It is usually dimensioned for fluid velocity less than 8 m/s (transcritical running).
The piping should always fall towards the unit, never away.
For double models, the link between the two coils should made on-site.
Connection to gascooler return
This pipe must provide a downward drain for condensation into the bottle (subcritical running).
It is usually dimensioned for fluid velocity less than 1,8 m/s (transcritical running).
Pairing of several gascoolers mounted in parallel
We recommend that the circuits are well balanced to avoid individual
gascoolers or a group of gascoolers mounted in parallel
becoming clogged

ELECTRICAL CONNECTIONS
General information
The machine is designed in accordance with EN60204-1.
All cabling on site must be made by qualified professional and must be in conformity with the legal standards in force in the relevant
countries and to EN60204-1.
Except for special operation, the nominal current must be 400 V for the power circuit.
Electrical motor wiring
In all cases the instructions shown on the gascooler connection box must be adhered to.
