SPLIT-SYSTEM UNITS 38NZ/NF & 40NZ/NF
Optional for the indoor unit 40NZ/NF
Outdoor environment Temperature - Thermal and acoustic insulation of the casing 30 mm thick, with reaction to ﬁre Euroclass A2-s1, d0. Corrosion - Coil with copper pipes and copper ﬁns. INERA® coil with copper pipes and ﬁns of an aluminium alloy, of high performance and great resistance to the corrosion (indoor unit and/or hot water coil). Coil with copper pipes and aluminium ﬁns with polyurethane and Blygold® coating (indoor unit and/or hot water coil). Condensates drain pan in stainless steel. Hot water auxiliary coil, with three-way valve, for heating in heat pump units. If the unit includes hot water coil and free-cooling, and works with negative temperatures of outdoor air, an anti-freeze thermostat as safety system is mandatory. Auxiliary electrical heaters. With this option, the air ﬂow controller is included. Installation - Antivibration mounts made of rubber. - Compatibility 2 x 1: two indoor units: 40NZ/NF and one outdoor unit: 38NZ/NF (models 200 to 360). • Two indoor units can be operated: * simultaneously, with a single control and a single terminal. * separately, each unit with its control and its own terminal. * two indoor units can be operated separately, each unit with its control board but with a single terminal (only with CARRIERrtc control and pLAN network). • The option of simultaneous operation is not possible for indoor units with supply plug-fan or mixing box. Safety Soft starter of the supply and/or return centrifugal fans which prolongs the set time mainly aimed at installations with cloth ducts. Differential pressostat for the detection of clogged ﬁlters. Differential pressostat for control of air ﬂow. Smoke detecting station in accordance with the NF S 61-961 standard. Refrigerant leak detector (with CARRIERrtc control). This allows prompt identiﬁcation of gas leaks, guaranteeing the safety of any people in the vicinity. Installation of the device ensures compliance with European standards F-GAS and EN378 as well as ASHRAE 15.
