MOUNTING AND SET-UP
QUALIFIED PERSONNEL ONLY, PROPERLY TRAINED AND QUALIFIED TO INSTALL AND
MPA 700 W EC A30/31/32 units are equipped with branch pipes for connection to circular air ducts.
MPA 1000 W EC A30/31/32, MPA 1500 W EC A30/31/32, MPA 2000 W EC A30/31/32, MPA 3000 W EC A30/31/32,
MPA 4000 W EC A30/31/32 units are installed in a system of rectangular air ducts that are connected either directly to the unit casing
or through the side panels.
The units are installed between the ducts, taking into account the direction of air flow, which is indicated by an arrow on the casing.
WARNING!
•
To reduce aerodynamic losses related to air flow turbulence, use shaped reducers in order to reduce or increase the cross-section
of air ducts.
•
To minimise turbulence-induced air pressure losses, connect the straight air duct sections on both sides of the unit. Minimum
straight air duct length: equal to 1 air duct diameter on intake side and 3 air duct diameters on outlet side.
•
It is necessary to protect the internal parts of the unit from penetration of foreign objects. For example, install a grill with a cell side
size of no more than 12.5 mm to prevent free access to the fan and foreign objects from entering the unit.
•
It is recommended to connect the duct through a flexible connection to reduce noise and vibration transmission. Such connections
allow compensating for possible mounting inaccuracies when connecting the unit to air ducts.
•
The equipment and air ducts that are to be connected must have their own mounting bracket in order to avoid transferring their
own weight loads to the unit.
The unit must be mounted so that it can be accessed for service purposes. Enough space must be provided for the cover to open all
the way. After removing the screws, the cover will hang on special cables.
Installation is possible on the ceiling or on the wall in such a way that the air flow is horizontal. In this case, the control unit can be
located both above and below.
The mounting is carried out at 4 points with mounting brackets. It is recommended to use anchor threaded rods with nuts for fastening
the unit. The vibration mounts on the unit casing must fit snugly against the ceiling or wall surface.
Fasteners for the unit mounting are not included into delivery set and should be ordered separately. While choosing fasteners consider
the material of the mounting surface and the unit weight. For selection of the fasteners for unit mounting please refer to a service
technician.
Install the outdoor temperature sensor in the air duct downstream of the unit along the air flow.
The units are available in the right- or left-side versions depending on the location of the control unit relative to the air flow direction.
