1 SAFETY PRECAUTIONS
All staff concerned must acquaint themselves with these
instructions before beginning any work on the unit. Any
damages to the unit or parts of it due to improper han-
dling or misuse by the purchaser or the fitter cannot be
considered subject to guarantee if these instructions have
not been followed correctly.
Warning
Only an authorised electrician or qualified service
personnel trained by Swegon shall be permitted to
carry out electrical installation on the air handling
unit or wire external functions to it.
1.1 To Start/Stop the Air Handling Unit
The air handling unit should normally be started and
stopped via the control display. Note that the control
equipment of the air handling unit is still electrified after
the unit has been switched off via the control display.
Pull out the plug connector before servicing the unit if not
otherwise specified in the pertinent instructions or in the
event of an emergency.
1.2 Risks
Warning
Before carrying out any work, make sure that the
power supply to the air handling unit has been
isolated.
Risk areas with moving parts
Typical moving parts are fan impellers and drive pulleys of
the rotary heat exchanger. Safety guards are provided in
front of these components. If the ducts are not connected
to the fan outlet, these must be fitted with a safety guard
(wire mesh screen).
Only a qualified electrician or trained service technicians
shall be allowed to remove the safety guards.

well as alarms.
The difference between the COMPACT Air and the COM-
PACT Heat units is that the COMPACT Heat units can also
be used for heating. 2.4 Environmental Documentation

temperatures, airflows and functions according to the
procedures in Sections 5-16.
Select whether the airflow unit of measurement shall
be l/s, m3/s or m3/h. (INSTALLATION LEVEL in the CON-
TROL DISPLAY menu).
Fill out the Commissioning Record and save it in the
document pocket of the air handling unit.
5. Activate, if needed, manual or auto operation (MAIN
MENU 2) or lock the speed of the fans (AIR ADJUST-
MENT menu).
6. Finish off with a filter calibration as described in Section

A neutral zone can be preset, which allows a lower supply
air temperature setpoint before regulation to a lower flow
rate begins. See 9.3.3.
When the supply airflow is regulated to a lower rate, the
heat exchanger will have ”excess heat”, i.e. warm extract
air, giving it capacity to maintain the supply air tempera-
ture required.
As the supply airflow is regulated to a lower rate, the air
pressure in the premises will become negative and this will
instead cause outdoor air to be sucked in through leakage
spots such as doors and windows. This outdoor air will
then be heated by the usual heating system of the prem-
ises.
Downspeed regulation to lower the airflow rate occurs
from the current preset flow (high speed or low speed),
down to half of this flow rate. The degree of regulation
to a lower rate is also limited by the min flow setting of
the unit. When preset flow for low speed is near the min
flow rate, the effect of this regulation to a lower rate will
be small.
