In damp conditions within the property, e.g. any locations
subject to steam and condensation such as a bathroom.
•
In a position subject to heat, e.g. above a boiler, cooker, or
radiator or where it will be in direct sunlight.
•
Where it can be reached and tampered with by children.
The EvoLink must be positioned such that there are sufficient
clearances all round it for installation, maintenance and to
allow the front cover to be removed. Refer to subsection 3.4 -
Clearances.

SYSTEM CLEANING
! CAUTION !
Grant recommends that the existing system be thoroughly
cleaned prior to commencing the installation of the Grant
EvoLink.
For optimum performance, and to avoid the danger of dirt and
foreign matter entering the EvoLink and Aerona³ air source heat
pump, the complete heating system should be thoroughly flushed
out before starting the EvoLink installation.
This should be carried out in accordance with the guidelines given
in BS 7593 'Treatment of water in domestic hot water central
heating systems'. This must involve the use of a proprietary
cleaner, such as Sentinel X300 or X400 or Fernox Restorer.
Grant also strongly recommends that a Grant MagOne in-line
magnetic filter (or equivalent*) is fitted in the heating system
return pipework when the EvoLink is installed. This should
be installed and regularly serviced in accordance with the
filter manufacturer's instructions.
*As measured by Gauss. The Grant MagOne magnetic filter has a
Gauss measurement of 12000.
3.7
