Benchmark places responsibilities on both manufacturers and installers. The purpose is to ensure that customers are provided
with the correct equipment for their needs, that it is installed, commissioned and serviced in accordance with the manufacturer’s
instructions by competent persons and that it meets the requirements of the appropriate Building Regulations. The Benchmark
Checklist can be used to demonstrate compliance with Building Regulations and should be provided to the customer for future
reference.
Installers are required to carry out installation, commissioning and servicing work in accordance with the Benchmark Code of
Practice which is available from the Heating and Hotwater Industry Council who manage and promote the Scheme.

WARNINGS
Metal Parts
This solar panel contains metal parts (components) and care should be taken when handling,
with particular regard to edges.
Risk of death from falls and falling objects
Observe the national regulations for working at heights.
Danger of burning and scalding
In case of solar irradiation inside the units, solar panels can reach 200°C.
Remove the sun protection lm installed at the factory only after the solar energy system has been started up.
Sealed Components
Under no circumstances must the user interfere with or adjust sealed parts.
Important Information
General
These instructions must be handed to the user on completion
of the installation.
This installation instruction applies exclusively to the mounting
of the solar collector.
The solar collector is one component in a solar system and
it is recommended that you read all other component(s)
literature prior to installation.
We accept no liability for any damage caused by failure to
observe these instructions.
Control of Substances Hazardous to Health
Under Section 6 of The Health and Safety at Work Act
1974, we are required to provide information on substances
hazardous to health.
The adhesives and sealants used in this appliance are cured
and give no known hazard in this state.
Solar uid
For solar uid safety data, please refer to Clearly Solar
System Hydraulics literature.
Manual Handling
With regards to the “Manual Handling Operations, 1992
Regulations”, this product exceeds the recommended weight
for a one man lift.
Recommend 2 person lift. Ensure safe lifting techniques are
used – keep back straight – bend using legs. Keep load as
close to body as possible. Ensure co-ordinated movements
during lift. Clear the route before attempting the lift. If
removing from truck straddle the load and tilt forwards to
facilitate secure grip. Do not twist – reposition feet instead.
Take care to avoid trip hazards, slippery or wet surfaces and
when climbing steps or ladders. Always use assistance if
required.
Installation of the solar collector will require a risk
assessment.
Testing and Certication
This solar collector is tested and certicated for safety and
performance. It is, therefore, important that no alteration is
made, without permission, in writing, by Glow-worm.
Any alteration not approved by Glow-worm, could invalidate
the certication, warranty and may also infringe the current
issue of the statutory requirements.
CE Mark
The CE mark on the solar collector indicates that it complies
with the basic requirements of the applicable directives as
stated on the data label.
Damage from lightning
If the installation height is more than 20m, electro-conductive
components must be connected to a lightning protection
device.
Frost Protection
Under no circumstances should water be in the solar collector
if there is a danger of frost.
After pressurisation and ushing, the solar collector(s) may
contain water residue.
Water remaining in the solar circuit will dilute the uid.
Immediately ll the solar system with solar uid. Check the
uid concentration with a frost protection tester.

Statutory Requirements
IMPORTANT
Where no British Standards exists, materials and equipment
should be t for their purpose and of suitable quality and
workmanship.
The installation of this solar collector panel must be carried
out by a competent person in accordance the rules in force
in the countries of destination.
Manufacturer’s instructions must not be taken as overriding
statutory requirements.
Statutory Requirements
In GB, the installation of the solar collector panel must comply
with the requirements of the current issue of the following
regulations:
The manufacturer’s instructions supplied.
The appropriate Buildings Regulations either The Building
Regulations, The Building Regulations (Scotland),The
Building Regulations (Northern Ireland).
Working at Heights Regulations 2005.
Connecting thermal solar appliances.
Lightning protection requirements.
Equipotential bonding of electrical installations.
The Health and Safety at Work Act
Control of Substances Hazardous to Health (COSHH).
The Current I.E.E. Wiring Regulations.
The Water Supply (water ttings) Regulations 1999 or the
Water Byelaws 2000 (Scotland).
Where no specic instructions are given, reference should be
made to the relevant British Standard Code of Practice.
Regulations for the prevention of accidents
At all times follow the national regulations on working at
heights.
Make sure there is suitable safety equipment such as
scaffolding or protective walls to prevent falling from roofs.
Fall protection systems such as the Glow-worm fall protection
system (item no. 0020054985) also has a fall arresting device
if the roof scaffold and protective roof wall are inappropriate
for the specic task.
Only use tools and equipment such as lifting gear or ladders
in accordance with the lifting regulations.
Cordon off areas below the working area sufciently to protect
people from falling objects.
Mark the working area, for example with warning signs as
described by the national regulations.

1 Technical Specication
Design Description
The Clearly Solar, solar at plate collector, collects the
available solar radiation and transfers the heat through the
solar uid to be utilised by the system.
It has been designed to compliment the complete range of
Glow-worm solar system components.
The kits are suitable for at roof or at surface installation.
The solar thermal at plate collector includes a saltwater-
resistant aluminium frame as well as a copper surface
absorber with a high selective coating.
The at plate collector has a CFC-free, standstill temperature-
resistant mineral wool insulation for long-life and excellent
heat insulation.
Hydraulic connections are tool free with double ‘O’ ring
sealing. The sensor sleeve is integrated into the hydraulic ow
connection.
Hydraulic connections are push-t with double ‘O’ ring
sealing. The sensor sleeve is integrated into the hydraulic ow
connection.
IMPORTANT: The completed works shall comply with all
necessary BS EN Standards and Codes of practice as well
as Building control or planning requirements, these should be
conrmed where necessary by notication to building control
or the appropriate competence based notication body.
The following kits are available and dependant upon the
