Instructions for assembling roofs for outside installation
The roofs of the base unit are composed of two parts
(1+2); one part has an accessible panel(1) for allowing the
flat filters to be serviced. The two parts should be joined
together using the metric screws supplied. It is recom-
mended that every point where water might infiltrate be
sealed with silicone. Also coming with the delivery are:
an appendage (3) for protecting the speed controllers from
solar irradiation; a frame (4) that is fixed to (2) if there are
no accessory modules. Both the appendage (3) and the
frame (4) should be fixed to the roof with the bolts and
screws provided. Then the roof should be fixed to the side
of the unit with the bolts and screws provided. The roof
should protrude on the electrical panel side, while it will
be flush with the other three sides.
Base unit roof (TPE)
Roof accessories are composed of a single piece that
should be mounted on the top of the accessory itself with
the bolts and screws provided. The roof accessory has a
raised part that should be above the part of the roof of
the base unit when the accessory is joined to the machi-
ne. The frame (4) needs to be removed from the roof of
the base unit in order to allow the raised part of the roof
accessory to cover the side of the roof of the base machi-
ne (5). The two strips of the roof resting on each other will
have to be properly sealed with silicone.
