I.CLINICAIR INSTALLATION INSTRUCTIONS
Switch cabinet can be placed on the left or on the right side of the unit.
Air Intake Air Supply
Air Supply Air Intake
Switchboard Switchboard
on the right on the left
Switch cabinet on the right side of CLN BD Switch cabinet on the left side of CLN BD
Attention: All plans of this manual are valid for the units with switch
cabinet on the left side.
For the units with switch cabinet on the right side air intake and air supply
are reversed as well as maintenance access for CLN BD
(See picture above).
To view the configuration of the switch cabinet refer to the individual
specifications of CLINICAIR®.
The installation must be carried out taking into account the following:
Access for maintenance from individual front panels (see unit plans).
Thermal and sound insulation of the ducts.
Installation of flexible sleeves at the air intake and air supply.
Installation of the unit with the help of adjustable feet provided with the unit.
Do not stand the unit against the wall to avoid any vibration.
Do not leave the cables on the floor under the switch cabinet.
If CLINICAIR® is placed on the floor provide ventilation of the switch cabinet.
If CLINICAIR® is isolated from the treated area by the reverberant wall made
of laminated plaster or wood, precautions must be taken to eliminate
reverberant effect. Contact an acoustic specialist.

WARNING: There is no definite link between water hardness and water conductivity.
IMPORTANT WARNING: Do not use water softeners! They will cause
foaming leading to potential disfunctionning.
AVOID:
• Use of well water, cooling circuit water, chemically or bacteriologically
polluted water.
• Adding disinfectants or anticorrosive components into water as they are
potentially irritant.
