Introduction
The following check list has been prepared to assist you in
understanding the differences from other types of heating
systems you may have installed and help to understand
and comply with all of the technical details contained
within this document to ensure a successful installation.
System cleaning and Water Characteristics
• In the case of a new installation, or cleaning the circuit,
it is necessary to perform a preventive cleaning of the
system. In order to guarantee the good operation of the
product, each time you clean the system, replace the
water or add glycol, check that the liquid appears clear,
without visible impurities and that the hardness is less
than 20°f
• To help protect the heat pump from any heating system
contamination; the system filter should be fitted
internally on the return pipe.
Recommended system cleansers and inhibitors are listed
below.
Fernox F3 System Cleanser
Fernox HP-15c combined antifreeze and inhibitor
Sentinel
All external connecting pipe work should be suitably
insulated using Armaflex or similar.
Radiator System Circuit
• As the Aeromax Plus generates lower temperatures
than a conventional boiler the radiators should have
been designed to suit the lower mean temperature.
• The basic controls within the standard installers pack
and the parameters on the heat pump are optimised
for use on radiator systems.
Retrofit Situations
• The heat exchanger should be protected from
particulate contaminates in the water circuit. The
existing radiator circuit must be chemically cleaned
and thoroughly flushed before installation when fitting
in a retrofit situation.
