Fix rubber seals around the mouths of the air intake and discharge to ensure an airtight fit; 18-20mm thick self-
adhesive closed-cell neoprene rubber tape is recommended.
Apply a layer of builder’s silicone to the joint between the top cover of the unit and the wall, to prevent rain from

EXTERNAL AIR INTAKE (0121…0331 models)
WM 0121…0331 units are available in the following versions with different
external air intakes:
• WMA; the lower front panel is completely closed (fig. 11. - panel C);
• WMF, with external air intake for the free-cooling cycle and motorised
control damper.
The quantity of external air is variable from a minimum value (set using
the microprocessor control) to 100% of the air discharged into the air
conditioned environment. It is taken in via a special opening mounted
on the front panel (fig. 11. -panel C2) - which contains a washable
metal pre-filter to protect against the entry of leaves and insects.
The expulsion of air from the air conditioned environment is via an
aperture connected to the lower lateral grilles (D).
