EVO-S COMPACT
COMPACT AIR HANDLING UNIT
OPERATION AND MAINTENANCE MANUAL
If the electrical switchboard is located in a different room
than the unit, it is absolutely necessary to install a START-
STOP switch (with interlock) in the room where the unit is
installed (as close to the unit as possible) for service switch-
-off of the unit. The service switches, providing the ON/OFF
signal for the unit control panel, are standard equipment of
the unit.
3.4.3 Draining out condensate
In the drip trays of the cross-flow exchanger and cooling
block, there are drain stubs leading to the outside of the
unit. Drain traps should be connected to the stubs to ensure
proper condensate drainage and prevent air suction. Traps
are included in standard delivery of the unit.
The trap used is an all-purpose device and may work on the
suction (underpressure) and pressing (overpressure) side
of the fan. The only requirement is a correct installation in
terms of the direction of flow on the condensate system -
the correct direction of installation is shown on the lid.
For a trap working on underpressure an appropriately
high terminal should also be made out of supplied PVC
pipes, working out value X where the trap is going to
operate.
For a trap working on overpressure, additionally the lid
should be opened, the black rubber plug removed, and
then the lid should be closed. The siphon trap set is also
equipped with additional installation instructions.

3.5 Unit start-up
Start-up and operation of the air handling units may be per-
formed by authorized persons with theoretical and practical
knowledge of a given air condiioning or ventilation system
(in accordance with the Ordinance of the Minister of Labour
of 15.03.1989 on additional qualification requirements for
persons involved in the operation of power equipment).
Before start-up:
1. Check the correctness of connection and tightness of
installations connected to the unit.
2. In the filtering block, remove the foil from the filters (if
new), check cleanliness of the filters and their mounting
in the guides.
3. Check fixing of heaters and coolers along with their
equipment,
4. In the fan block, check the state of fastening of the fan
unit.
5. Check the condition of electrical connections and the
wiring to avoid rubbing electric wires against moving
parts.
6. Check that the fan rotor does not rub against the inlet
funnel mounted on the diaphragm during rotation.
7. The fan EC motors must be connected according to the
scheme shown in Fig. No. 27 (single-phase EC) and Fig.
No. 28 (three-phase EC).
