4.2
As a rule, the unit is to be stored and/or transported in its shipping container in the upright
position and without water charge. For transport over short distance, and provided due care is
exercised, an inclination angle of up to 30 degree is permitted. Both during transport and
storage, ambient temperatures of -5 to 43 are permissible.
4.2.1 Transport using a fork lift
When transported by a fork lift, the unit must remain mounted on the pallet. The lifting rate
should be kept to a minimum. Due to its top-heaviness, the unit must be secured against
tipping over. To prevent any damage, the unit must be placed on a level surface!
4.2.2 Manual transport
For the manual transport, the wooden pallet can be used for bottom part.
Using ropes or carrying straps, a second or third handling configuration is possible. With this
type of handling, care must be taken.
Permissible inclination angle of 60 degree is not exceeded. If transport in an inclined
position cannot be avoided, the unit should be placed into operation one hour after it has been
moved into final position.

WARNING
For continued safety of this appliance it must be installed, operated and maintained in
accordance with the manufacturer's instructions.
If the water supply pressure exceeds the rated pressure, a pressure reducing valve is
tube fitted when installing the unit.
The water may drip from the discharge pipe of the pressure relief device and that
this pipe must be left open to the atmosphere.
The pressure relief device should be operated regularly to remove lime deposits
and verify that it is not blocked.
A discharge pipe connected to the pressure relief device is to be installed in a
continuously downward direction and in a frost-free environment.
Facilities ford raining and filling of systems shall be provided where these a
required for servicing purposes. The drainage facilities, where fitted, shall beat the
lowest point in the closed circuit.
