Installation of Covering Roof

An air-handling unit installed outside must be protected by a covering
roof against water penetration. Below, you will find the installation
procedure for the joint-less covering roof equipped with weather
moulding, which is delivered as an accessory.
First, spread all the individual parts out in a free area. Images including
precise locations of covering roofs are included in the accompanying
technical documentation delivered with each air-handling unit. The
covering roof consists of individual partial roofs and connecting bars,
and also covers of the cross joint if the air inlet and outlet are situated
in a parallel position. As standard, the covering roofs delivered are
made of galvanised (Z275 g/m
RAL 9002 polyester coating. Other designs of covering roofs can be
delivered upon agreement with the manufacturer.
Material needed for the covering roof installation:

Sealant (included in the delivery)
 Roof screws 6.5 x 18 (included in the delivery)
 Pliers (min. opening of 35 mm)
Installation procedure:
 First, following the attached assembly lay-out, lay out individual
parts of the covering roof and centre them on their intended spot.
 Begin the installation by fixing one specific roof (e.g. the roof
with opening, rotary heat exchanger roof, or electric or water
heater roof, etc). Before installing the next section of the roof, it is
necessary to apply silicone sealant on the contact surfaces of the
adjoining roofs (see figure # 11).

After finishing the roof installation, apply a second protective layer
of silicone sealant on all joints (see figure # 11).
 Any gap and/or joint leakage (corners, open faces of protecting
mouldings, incl. grooves, cross-butt joint, etc.) must be sealed with
silicone sealant. Then, fix and seal the covers of the cross-butt joint
(see figure # 13).
 Make the roof completely waterproof by sealing the bottom side of
the roof and the top edge of the side panel (see figure # 14).
