The Mikrofill 3 is a fully automatic sealed system filling device and is suitable for the water management in
domestic and commercial heating and cooling systems. It is designed for use in a normal environment.
It is not
suitable for installation outside, or in environments where there are excessively cold temperatures
.
INSTALLATION
All Mikrofill products should be installed by a competent person with regard to the relevant requirements of
the Health and Safety Regulations, Building Regulations, IEE Regulations, Water Supply (Water Fittings)
Regulations, Water By-laws (Scotland) and any other by-laws or planning requirements.
The Mikrofill 3 is WRAS approved with certificate number
1806078
.
It is intended for wall mounting (see
page 08
) and should be mounted at such a height as to enable the
display to be easily read.
MAINS / BOOSTED COLD WATER SUPPLY
The Mikrofill 3 is designed to be connected directly to the mains cold water supply, or a boosted cold water
supply. The unit is supplied complete with all necessary isolating valves and incorporates a basket filter in the
inlet ballofix valve.
A flexible hose is supplied with the unit which
MUST
be connected to
the inlet ballofix valve, as shown in the diagram to the left. Failure to
do so may result in damage to the inlet pressure sensor due to water
hammer, resulting in a
SENSOR FAILURE
. Under such circumstances,
this would not be considered a warranty fault.
The water inlet connection is 15mm compression and should be
connected to the mains cold water supply by 15mm copper pipe or
equivalent approved plastic pipework.
If the Mikrofill 3 is sited some distance from the mains cold water
supply it may be advisable to install a single check valve adjacent to
the mains cold water supply.
To reduce the pressure drop on very long supply routes 22mm supply
pipework is recommended.
FILL PRESSURE
The Mikrofill 3 is capable of filling a system to within 0.3 bar of its
current inlet water pressure.
Where the incoming water pressure exceeds 5 bar please contact
our technical department on
03452 60 60 20
for further installation
information.
