Pumps The pump installed in a unit 30PHC can be replaced for: - High-pressure, monocellular, IP55, circulation pump that can operate with glycol water (mono-ethylene glycol). - Low-pressure, monocellular, IP55, circulation pump that can operate with glycol water (mono-ethylene glycol) (except model 90). Configuration - Vertical air supply, M01 assembly (default horizontal supply, M00 assembly). - In the STD version: Different configurations of available pressure from 7 to 35 mm.w.c. Climatic conditions - In units with the STD version that work in cooling with an outdoor temperature lower than 12ºC, the condensation pressure control allowing an “all seasons” operation (up to -15ºC) is mandatory. This is performed per motorized damper in the fan outlet. Flexible ducts for supply and return air. Flexible hydraulic connections (500mm), supplied in the kit. Available for: • Inlet / outlet of the unit. • Inlet / outlet of the desuperheater circuit. - For 30PH units, filter with stainless steel mesh (500 microns), supplied in the kit. Note: this filter is standard for 30PHC units. - Cut-off and water control valves, supplied in the kit. - High-pressure and low-pressure gauges in the cooling circuit. Energy recovery Desuperheater circuit which includes: - Thermally isolated, welded stainless steel plate exchanger for working in a closed circuit in the recovery of hot gases. - Draining valve and ball valve - Hot water recovery control thermostat. - Option for a 3-speed hot water circulation pump.

Coils protection: • Coil with copper pipes and copper ﬁns (upon request). • Coil with copper pipes and aluminium ﬁns with polyurethane and blygold coating. During periods with low outdoor temperatures, antifreeze protection for the unit: • Electrical heaters in the condensate drain pan. Mandatory when outdoor temperatures are below 3°C. • Operation with glycol water up to a minimum outlet temperature of -10ºC. Thermal insulation of the body 18 mm thick. Mandatory with negative conditions. • Anti-freeze protection with ﬂexible electrical heaters around the pipe of the hydraulic circuit.

Electric panel - Compressor soft starter. - Transformer for power supply without neutral. - Voltage 400 / 440V - 60 Hz (upon request). - Energy meter for monitoring of the power consumption of the installation. Control / communications management - TCO user terminal, for remote control. - RS485 serial cards for network communication with protocols: Carel, Modbus, LonWorks®, BACnetTM MSTP, Konnex. - Ethernet pCO Web card for network communication with protocols: Modbus TCP/IP, BACnetTM Ethernet, TCP/IP, SNMP V1-2-3, FTP and HTTP.
Installation - Antivibration mounts made of rubber. - Protection grille for the coil. - Gravimetric filters in the return air. The filters frame is removable, and upon request, it is possible to supply the frame independently with the unit, to be joined on site. 446
