2.4 Benchmark
Vaillant is a licensed member of the Benchmark Scheme.
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 a competent person approved
at the time by the Health and Safety Executive 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.
Benchmark is managed and promoted by the Heating and
Hotwater Industry Council.

4 Installation
4.1 Observing the requirements for the
product's installation site
Caution.
Material damage due to frost
If the water in the system freezes, there is
a risk of damage to the domestic hot water
cylinder.
▶ Install the cylinder in a dry, permanently
frost-free room.
Caution.
Material damage due to escaping water
In the event of damage, water may escape
from the cylinder.
▶ Select the installation location so that, in
the event of damage, large volumes of
water can be drained safely (e.g. into a
floor drain).
Caution.
Material damage due to high load
When filled, the cylinder may damage the
ground on which it stands due to its weight.
▶ Take into consideration the weight of the
filled cylinder and the weight-bearing capacity of the floor.
▶ If required, reinforce the installation area.
Select a sensible installation site and take into consideration
the routing of the lines.
Install the cylinder as close as possible to the heat generator
in order to minimise heat losses.
Set up the product in a suitable location in a room and, when
doing so, pay attention to the following points:
– Plan the installation of the tundish (→ Page 9).
– The installation surface must be even and have sufficient
load-bearing capacity to support the operating weight of
the product.
– The installation site must be frost-free.
– Install the product in such a way that the thermostat and
immersion heater can be accessed easily.
– Leave sufficient space around the product for installing,
maintaining and replacing the expansion vessel.
To prevent energy losses, the lines must be provided with
thermal insulation that complies with the applicable thermal
insulation regulations.
4.2 Transport
Caution.
Risk of material damage caused by incor-
rect transport.
The components must not be used to transport the cylinder. Otherwise there is a risk
that the cylinder could malfunction.
▶ Do not use the cylinder's components to
transport it.
Always transport the unit as illustrated above.
Never transport the unit while it is horizontal.
4.3 Unpacking the product
1. Remove the product from its box.
2. Remove the protective film from all of the product's
components.
