Installing without a pipework system
Without the pipe system
The air is drawn into and conducted away from the same
room .
With this installation type, the room is used as an energy
collector. The room is cooled by the hot and cold air that the
product emits.
Caution.
Risk of material damage caused by frost
inside the house
Even at outdoor temperatures above 0 °C,
there is a risk of frost in the installation room.
▶
Use suitable heat insulation to protect
pipelines and other elements in the install-
ation room that are sensitive to cold.
To prevent the cold air emitted by the product from re-enter-
ing it, maintain the minimum clearance between the upper
side of the product and the ceiling.

Caution.
Risk of damage caused by heat transfer
when welding.
The heat that is transferred during welding
may damage the cylinder and its components
as well as the connection seals.
▶
Protect the product and its components.
▶
Do not weld the connection pieces if these
have been screwed into the pipe fittings.
Caution.
Risk of material damage by drilling
through the product.
The product may be damaged by drilling
work.
▶
Do not drill through the product.
Caution.
Risk of material damage to the cylinder.
If an unvented hot water cylinder is fitted at
a high level (eg, loft space), potential dam-
age to the cylinder may occur if the correct
method of draining is not followed.
▶
In certain circumstances and at the dis-
cretion of the installer, install a WRAS ap-
proved automatic air vent on the hot water
outlet at the highest point.
