3.5 OPERATION CONDITIONS
The unit can be used in rooms normal according to IEC 60364-5-51, resp.
ČSN 332000-5-51 ed. 3, ČSN 332000-1 ed.2. The ambient
temperature must be between -20 and +40 °C.
The unit can transport air without solid, fibrous, sticky, aggressive chemical and explosive additives. The maximum permissible supply air
temperature must not 40 °C. The maximum humidity of the air flowing through the unit is 17 g / kg s.v. (84 % r.h. at 25 °C).
If, due to the immediate climatic conditions, the humidity of the outdoor intake air reaches 100 % r.h. (wet steam), it is at the operator's discretion
whether to keep the unit running with the risk of temporary separation of moisture on the internal parts
of the unit (eg filters, flaps,…). This
humidity cannot be the subject of a complaint.
CAUTION!
!
Units with direct evaporator (marked DX and DXr in the unit code) must be equipped with a mixing flap (MX in the unit code)
ensuring as needed the min. temperature at the condenser/evaporator inlet temperature of +10 °C.
CAUTION!
For units with a direct evaporator (marked DX and DXr in the unit code), the
design air flow through the unit must be
observed
when operating the direct evaporator/condenser. It is acceptable to reduce the flow in cooling and heating mode by a
!
maximum of 20 % of the design air flow. For proper operation of the direct evaporator, it is necessary to observe the necessary
heat or cold consumption from the heat exchange surface of the evaporator/condenser. If the design amount of energy is not
consumed, the condensing unit / heat pump may report a fault in the pressure protections (LP, HP) of the cooling circuit and the
condensing unit / heat pump may cycle in ON/OFF mode.
