The client must unwrap the goods in the presence of the driver.
Claims must be made at the time of delivery and be described in detail.
Introduction to the range:
Magister is a range of precision close control units (temperature and humidity) that is specifically adapted to meet the needs of
premises with high heat loads or of sensitive locations (data centers, computer rooms, metrology laboratories, etc.).
The MAGISTER range is available with two types of operation:
- Chilled water (CW)
- Direct expansion (DXA) linked to two air-cooled condensers
The description of the unit is indicated using the following format:

If the unit is lifted using a spreader beam and slings:
- Protect the panels.
- First remove all the caps covering the holes for the tubing on the lower section of the equipment. (Fig. 1).
- Use tubing (Ø max. = 40mm) with a sufficient lifting capacity (see weight table).
- Use fabric slings.

Under no circumstances should these vertical units be installed in an atmosphere that is:
- Explosive
- Flammable
- Corrosive
or dusty.
Once at the place of installation, remove the wooden blocks.
● Different configuration options are possible:
The unit can be placed directly on the floor. In this case:
The unit must be placed on a flat, smooth surface which is as level as possible (ratio of approx. one to one thousand).
The cabinet frame must rest fully on its contact surface.
The unit need not be anchored to the floor if it is operated under normal conditions.
Or on one of the following bases:
Support base, cased base with grids, cased base with damper.
(See the technical characteristics for these options in paragraph 12.2).
It should be placed on a floor that is as level as possible.
Each base comes with feet, which allow the height to be adjusted (in the event of a raised floor) and the base to be levelled
before placing the unit on top.
Before placing the vertical unit on top, an adhesive seal (supplied with the option) is to be placed on the aluminium casing frame
to ensure its tightness.
The cabinet can also come with a plenum with grids or a free-cooling plenum.
(See the technical specifications for these options in paragraph 12.2)
Before placing the plenum on the vertical unit, apply the adhesive seal (supplied with the option) to its tightness.
For some models (CW115 and DXA) and for practical reasons, when the unit is in its final position, the horizontal gussets (with
oblong stamped holes), located at the bottom of the unit, can be removed (see photo).
