Installation and operating instructions
1.2 Limits of use for cooling
Due to its generously dimensioned basic construction and low basic fan
speeds, the cooling model is fundamentally used with air dehumidification.
Nevertheless, specific operating modes and settings need to be taken into
account for cooling mode:
• Never move the louvre slats into the end positions, e.g. to shut off
a discharge opening. In particular at high fan speeds, there is a risk
that water droplets could be carried into the other air outlet fields by
inadmissibly high air speeds.
• Only operate the following units at a maximum fan speed of 680 rpm:
• EC design: type 963133 / type 964133
• Three-phase model: type 963136 / type 964136
• Single-phase model: type 963116 / type 964116
• Refer also to the table in chapter 5 “Technical data”.
• To prevent impermissibly severe cooling down of the housing when
the fan is at a standstill, we would recommend the use of valves (e.g.
thermoelectric shut-off valve with recirculating mode).
This counteracts the outer parts of the housing from experiencing
condensation, especially with extreme conditions involving very high
levels of humidity.
1.3 Condensation pump
The self-priming condensation pump is fixed to the hose connector for the
on-site condensation pressurised line.
This ultra-quiet, electromagnetically operating pump is mounted together
with the upstream condensation filter on the upper side of the unit.
Max. delivery height:
8 m with max. 4.5 l/h flow rate and a hose length of
10 m
Max. pump volume:
approx. 18 l/h with 0.5 m delivery height and a hose
length of 2 m
Supply voltage:
230 V/50 Hz (separate power line needed)
Power consumption:
14 W
Condensation pressure line:
DN 6 mm (hose connection)
Signal contact for
condensation overflow
Normally closed (NC) contact, potential-free switch
capacity 230 V/5 A
