1.3.5 Risk of injury or material damage
due to incorrect handling of the
product
Using the fins on the front side of the product
as conductors may lead to injuries (due to
falling) or to material damage.
▶
Do not use the fins as conductors.
1.3.6 Risk of material damage due to
additional elements in the heating
water
Unsuitable frost and corrosion protection
agents may damage seals and other com-
ponents of the heating circuit and may there-
fore also lead to leaks in the water outlet.
▶
Only add approved frost and corrosion
protection agents to the heating water.
1.3.7 Risk of material damage caused by
using an unsuitable tool
▶
Use the correct tool to tighten or loosen
screw connections.
1.3.8 Avoid environmental damage
caused by escaping coolant
The heat pump contains R410A coolant.
The coolant must not be allowed to escape
into the atmosphere. R410A is a fluorinated
greenhouse gas covered by the Kyoto Pro-
tocol, with a GWP of 1725 (GWP = Global
Warming Potential). If it escapes into the at-
mosphere, its impact is 1725 times stronger
than the natural greenhouse gas CO
2
.
Before the heat pump is disposed of, the
coolant it contains must be completely
drained into a suitable vessel so that it
can then be recycled or disposed of in
accordance with the regulations.
▶
Ensure that only officially certified com-
petent persons with appropriate protective
equipment carry out maintenance work on
the coolant circuit or access it.
▶
Arrange for the coolant contained in the
product to be recycled or disposed of by
accredited specialists in accordance with
regulations.
▶
Only use coolant R410A.
▶
Only use a suitable R410A tool for the
filling, pressure measurement, vacuum
generation and discharge.
▶
Solder the lines using shielding gas. Check
the lines for leak-tightness using nitrogen.
▶
In the event of a repair or maintenance
work, fill the coolant circuit with liquid
coolant.
▶
If the coolant circuit is not leak-tight, check
which component must be repaired or re-
placed.
▶
Lower the negative pressure in the coolant
circuit to max. 10 mbar (1000 Pa).
▶
When filling the coolant circuit, observe the
values in the "Technical data" section.
1.4
Regulations (directives, laws,
standards)
▶
Observe the national regulations, stand-
ards, guidelines and laws.

Local regulations
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 instruc-
tions by a competent person approved at the
time by the Health and Safety Executive and
that it meets the requirements of the appro-
priate Building Regulations. The Benchmark
Checklist can be used to demonstrate compli-
ance 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 accord-
ance with the Benchmark Code of Practice
