■■ Version with circulation pu mp included (30PAC)
This version includes, in the same casing that the 30PA
version, the following components:
-- Monocellular IP55 centrifugal circulation pump that
can operate with glycol water (mono-ethylene glycol).
The pump must be changed for mono-propylene
glycol (upon request).
-- Closed expansion vessel.
-- Safety valve with a tare value of 4 bar and draining
valve.
-- Air bleeder valve (model 160HEE and 180HEE).
-- Filter with stainless steel mesh (500 microns), supplied
in the kit for installation by the installer.
COOLING
Unit components
HEE Version (High Energy Efficiency):
• Variable speed electronic plug-fan(s) with
condensation pressure control which adapt their
rotation speed to the installation requirements,
thereby reducing electricity consumption, the sound
level at partial charge, and improving the average
seasonal output of the unit (ESEER).
• Energy-efficient ErP 2015 motor, Class F, IP54, and
internal thermal protection.
■■ Cooling circuit
-- Hermetic scroll-type compressor, with acoustic
insulating cover, assembled over antivibration mounts.
Control of phase equilibrium and the direction of
rotation.
-- Crankcase heater.
-- Thermostatic expansion valve with external
equalisation.
-- Anti-acid dehydrating filter, and liquid sight glass.
-- Liquid receiver (heat pump units).
-- Four-way cycle reversing valves (heat pump units).
Circulation pump
■■ Protections
-- High and low pressure pressostats.
-- Differential pressure switch for control of water flow.
-- Water anti-freeze protection built into the control,
depending on the temperature measured by the
probe placed on the exchanger outlet.
-- Refrigerant anti-freeze protection.
-- Compressor discharge temperature control.
-- Non-return valve built into the compressor discharge.
-- Compressor thermal protection.
-- Main door switch.
-- Automatic switch in the control circuit.
-- Magnetothermic protection switches for the
compressor and fan motor power line.
-- Timing the disconnection of the circulation pump.
-- Failure safety device for the circulation pump.
■■ Electric panel
-- Complete and fully wired electric panel. Insulated
panel cover to prevent condensation.
-- IP55 protection.
-- Power supply with neutral and main ground
connection.
-- Compressor and fan motor contacts.
■■ Indoor circuit
-- Thermally isolated, welded stainless steel plate
exchanger.
