Installation Instructions

1. Before you start installing the solar water heater, please read

carefully all the installation instructions stated and illustrated
in this manual.

2. Before the installation of the solar water heater, it is very

important that the customer and the installer agree on all
the details concerning the correct and safe installation of the
appliance, (such as location, placement point, static resist-
ance and control of the surface on which the appliance will
be placed, piping and wiring run etc).

3. The installation should be done according to the local electric

and plumbing regulations.

4. The location you will choose for the installation of the solar

collector(s) should not be shaded by any obstacles (trees,
buildings...etc.) all around the year. (see obstacle table here
below).

5. For optimum performance of the solar system, the

collector(s)  must  face  South,  for  countries  located  in  the
Northern  hemisphere  and  North  for    countries    located    in
the  Southern  hemisphere.  In  case  that  it  is  not  totally
possible  for  the  solar  collector(s)  to    face    the    equator,
you  must  turn  it  (them)  towards  East  up  to  30º  if  major
hot  water  draw  is   before   14:00   p.m.,   or   towards   West
up  to  30º  if  major  hot   water   draw   is   after   14:00   p.m.
The ideal inclination of the solar collector(s) should be equal
to the latitude in which the installation is done.

6. The support base of the collector(s) is the same for both

flat and inclined roofs. It is diversified only in the way of
it’s assembly (see installation instructions on the following
pages.)

7. If the surface on which the solar collector(s) will be installed

(inclined or flat) is not compatible with the standard equipment
supplied with each appliance, then alternate equipment must

be used. The installer has to choose, propose and install this
alternate equipment, always under the concurrent opinion of
the customer.

8. For installation on an inclined roof, the «D» plates must be

screwed with the appropriate screws and nuts on the roof
timber, in order to secure the right and safe installation of
the collector(s).

9. In regions subject to heavy snowfalls, rainfall, storms, strong

winds, cyclones, tornadoes it is very important to ensure
that the supports of the standard equipment are sufficient to
withstand the weight of the expected snow or the intensity of
the weather conditions. In these cases the collector(s) must
be placed in a stable way on the roof and must be tightened
with additional metal straps.

Continuity  in  pipe  work  insulation  must  be  maintained,
although, sometimes,  many  lengths  may  need  to  be  joined  to
cover  the full  length  of  pipe work.  In  those  instances,  the  join
should  be  taped  and  UV-resistant  tape  used  where  the  join
is  made  on  external pipe work.
Where  pipe  work  penetrates  the  roof  material,  the
insulation  should  go  through  the  penetration  with  the  pipe
work, as shown in figure on the right.

Roof  penetrations  for  pipe work,  electrical  conduits  or
support frames  should  be  sealed  with  roof  lashings  to
prevent  water leaking  into  the  roof  cavity.  These  lashings  are
usually  made  of  EPDM  or  silicon  rubber,  with  an  aluminum
frame  that  can  be mounded to the shape of the roof, as
shown in figure below.

Where possible, penetration should

be done on the high part of the roof profile to avoid the
possibility that water will pool around a penetration that
is located in the valley

of the profile.

Lead lashing should not be used on a roof that is collecting
rainwater for drinking and it must be compatible with other roof
cladding material.
