Introduction, Health & Safety, & Post Installation
Introduction
This installation manual contains essential information for the effective and safe installation of RM
Solar products. It is essential that this kit is tted by someone with relevant training or previous
experience in the eld of Solar Thermal, if this kit is installed without prior training or qualication
your guaranteed may be void and your help limited.
This technical documentation should be available with you at all times during the installation, but
prior to installation please read these instructions as in many cases it will prevent problems from
occurring during the installation process.
Health & Safety Information
RM Solar panels are high quality thermal solar panels using selective coating technology to convert
light into heat. RM Solar panels should only be tted by authorised, trained and qualied personnel.
They are not intended to be a “do it yourself” product. Panels are also sometimes called “solar
collectors”.
When tting the panels installers shall comply with all relevant health and safety regulations and
shall carry out a suitable and sufcient risk assessment before any work commences.
Post Installation
After the correct and full installation and commissioning of the RM Solar system please make sure
you take the following steps:
In The Manual Please:
• Complete the product guarantee form included with the solar kit.
• Complete the product commissioning certicate.
Ensure that you:
• Explain how the system works and how to get the best from the system to the customer.
• Make sure these instructions are left with the customer.
• Service the system in accordance with recommended guidance, and complete the log as
appropriate.
Pre Installation
• Please ensure all equipment is on site, and no parts are damaged.
• Please make a note of any solar panel serial numbers.

Section 1 - Product Specications
S Class 20 Specication
RM Solar S Class 20 solar panel is a vertically mounted glazed collector with collection
pipes, intended for applications in systems equipped with circulating pumps.
The RM Solar S Class 20 panel is constructed with a single meander system piping without using
soldering or welding and is folded into the absorber plate; a single piece tray folded into the frame
holding the glazing.
The RM Solar S Class 20 panel is not intended to be used in drain-back systems.

• Dimensions : 1010 x 2010 mm
• Weight empty : 36.5 kg
• Fluid Volume : 1.3 litres
• Recommended ow of heat transfer uid : 30 L/h/m2 collector
• Stagnation temperature : 170°C
• Panel connection : in series

Section 2 - Panel Positioning
Positioning the Panels
South Facing Roofs
Positioning the collectors is important for optimum performance. Collectors should ideally be
mounting at an angle of between 30 degrees and 60 degrees on a south facing position that is not
shaded by overhanging trees, buildings, or structures. Good results can be obtained by positioning
the panels facing anywhere in an arc between south west and south east but due south facing pro-
vides optimum performance.
North Facing Roofs
It is not generally recommended that you install the panels on North facing roofs in the Northern
Hemisphere. South of the equator, north will provide the optimum performance and south facing the
worst performance.
East / West Facing Roofs
Good results can be obtained by splitting the collector array on East / West elevations but this should
only be used when it is not possible to have a mainly southernly position for the collectors. If you are
installing an East / West split system you have to double the number of panels that would normally
be required, e.g. a 2 panel system would require 2 panels on the east and 2 panels on the west.
East / West Facing Roofs (Alternate Conguration)
Another option is to oversize the collector area on the side of the roof chosen to mount the collec-
tors. E.g. If 2 panels would have been adequate had the roof orientation been south, then 3 collec-
tors would be required on either the east side or the west side depending on which recieved the most
sunlight.

Section 3 - On Roof Frames
On Roof Frames
The on roof frames from RM Solar come in the following two styles, choosing the correct frame for
your installation is paramount to an effective install.
Sharks Fin
Primarily suited to tile installs. For installation of this frame please see page 10
Slate Bolt
Primarily suited to slate installs, but will t most roof types. For installation of this frame please see
page 18
Note: It is important to note that the S Class 10 Panel is bigger than the S Class 20 product, so
when using on roof products remember to select the correct hole when locating the ‘Z’ rails.

Search for the rafters at the position of the collector eld. Push up or remove tiles on the total length
of the collector eld.
Using the wood screws provided mount the support pipe using the pipe brackets. The distance
between the lower batten and pipe centre should be 90mm. If more panels are added use the
extension bolts to join the pipes. Extensions must be mounted with 2 pipe brackets [4]. The end
brackets should not be more than 500mm from the end of the support pipe.

Screw the align screw [9] in the centre hole of the shark bracket. Now use the U-Bolt Bracket [6],
washer [7], and nut [8] to x the hooks to the pipes. Choose so that the brackets are placed under
the centre of the panel. Note: The outside Sharks n should not be more than 500mm from the
outer panel edge.
Warning: In areas of heavy snow: please replace roof tile with a metal tile, otherwise the roof
tile might break under heavy snow loads, or use the slate screw installation kit.

Screw the Z-Rail [11] [12] to the L-Rail [10] using two screws M6 and two washers [16] on each
connection. Maximum Distance from sharks n to the end of the Z-Rail must not be more than
500mm! If more than 2 panels are to be mounted use the frame connector as shown in g. C. Before
screws are tightened be sure that a cross measurement has been made. A = B.

Section 3 - Sharks Fin Installation
Place the panels in the correct position. In case of systems with more than two panels, mount
the panels starting in the middle. Do not forget to secure the panels together with any straight
connectors required (supplied in panel extension set) Mount the wind clamps [14] and connect the
panels.
Design of the wind clamps may vary - this will not effect the performance of the roof frame.
