Page 23: Drainage Of Condensate
™ EVERSKY X. DRAINAGE OF CONDENSATE X.1. Gravity evacuation As standard, the unit is designed for a drainage of condensate by gravity (without high point). The installation of a siphon is to be expected at the time of installation of the unit. Non-compliance with the installation rules of the condensate siphon can lead to an overflow of the condensate pan and an internal flooding of the unit that can cause damages to the equipment, damages, malfunctions, and endanger the occupants and staff. -
Page 24: X.2.C. Operating Principle
™ EVERSKY X.2.c. Operating principle The pump operates autonomously as soon as the unit is switched on. It is equipped with a level controller that automatically switches the pump on and off depending on the level of condensate in the condensate pan. As standard, the pump incorporates a NC (Normally Closed) dry contact that opens when the condensate level contained in the condensate pan reaches a critical level, see XIV GENERAL WIRING DIAGRAM. - Page 25 ™ EVERSKY X.2.f.2. Installation The transparent PVC tube must not pass through any The condensate exhaust pipe must never pass through a area that may cause condensate to freeze. section that could cause the discharged condensate to freeze. Step Description Remove the part of the tube that equips in standard the unit and acting for drainage by gravity.

Page 26: X.2.G. Installation Of The Anti-Siphoning Device
™ EVERSKY X.2.g. Installation of the anti-siphoning device If the end of the discharge tube is below the condensate lift pump level, there is a risk of siphoning the pump which can lead to its failure by repeated dry running. To avoid this, it is therefore necessary to install the anti-siphoning device supplied in the condensate lift pump kit. -

Page 30: Xii.1. Setting Up The Time Schedules
™ EVERSKY XII.1. Setting up the time schedules The operating principle of the EVERSKY unit is to continuously adjust the air flow according to the CO2 level measured in the room by acting on the fan speed in order to always optimize comfort and energy consumption. The time schedule is to be adapted according to the type of room occupancy, and according to whether or not the EVERSKY unit must maintain thermal comfort in this room. -
Page 31: Xii.2. Adjustment Of Ventilation Setpoints And Co2 Management
™ EVERSKY XII.2. Adjustment of ventilation setpoints and CO2 management The principle of CO2 control is to manage the speed of the fans (and therefore the airflow rate) according to the level of CO2 in the air in the room. The higher the CO2 level, and therefore the higher the occupancy rate, the faster the fans turn, and therefore the higher the airflow (air renewal). -
Page 32: Xiii.1.B. Electrical Connection
™ EVERSKY XIII.1.b. Electrical connection The filter pressure switch is of the NO type (normally open). The contact is open at rest and closes when the filter pressure drop (differential pressure) is higher than the setting (200 Pa at the factory). The pressure switch must be connected between terminals (1) and (3) according to the electrical wiring diagram. -
Page 33: Xiii.2.A. Setting The Tare
™ EVERSKY XIII.2.a. Setting the tare The nominal setting of fan pressure switches is 25Pa. There is no need to change the factory setting. This setting must be respected when the component can be replaced if necessary, which can be delivered on another setting value. The adjustment is simply done using a flat footprint screwdriver by turning the central element (1) so that the arrow (2) coincides with the set value. - Page 34 ™ EVERSKY Supply fan Extract fan Z-EN-V0623-CSY-INM-Zehnder Eversky, uk 34/47...
