•
Model and Local Authority Byelaws
•
BS 5720

IMPORTANT:
This appliance is CE certificated for safety and performance. It is important that no
modifications are made to this appliance, unless fully approved in writing by Johnson & Starley Ltd. If in
doubt, please Ring Johnson & Starley Ltd on Telephone 01604 762881.
*
The manufacturer’s instructions supplied must not be taken as overriding any statutory
requirements.
*
It is important that the system is flushed thoroughly before the appliance is left to operate (as
recommended in BS 7593) in order to maintain an efficiently operating heating system and to
prevent the boiler from becoming a trap for system debris. Once the system has been flushed,
an inhibitor (suitable for stainless steel heat exchangers) should be added. Appropriate inhibitors
are available, for example Sentinel, Fernox and Salamader.
*
We also recommend a Magnetic & Non Magnetic Filtration system be fitted between the last
radiator and the boiler. This protects the boiler from debris blockages in the heat exchanger and
prolongs the life of the boiler.
*
Failure to carry out the above procedure will invalidate the guarantee!

SAFETY INFORMATION
5.1
HANDLING THE UNIT
5.1.1
The weight of this appliance exceeds that recommended for a one-man lift. It will therefore
be necessary to gain assistance at times during the removal from its packaging and
during installation procedure. Manoeuvring the boiler may include the use of a sack truck
and involve lifting, pushing and pulling.
5.1.2 It should be noted that this appliance may contain sharp edges. Care MUST be taken
when handling the appliance to prevent injury. It is advised that engineers wear suitable
P.P.E. when handling the unit.
5.1.3 Once the appliance has been fired beware that certain parts will be hot to the touch.
5.1.4 Do not install flues during rain, high winds or in severe weather conditions.
5.2
ELECTRICAL SUPPLY
5.2.1
Ensure the mains supply voltage, frequency, number of phases and power rating comply
with details on the rating label.
5.2.2 All wiring must be in accordance with the appropriate standards.
5.2.3 Ensure safety regulations and practices are adhered to when installing and using this
appliance.

GENERAL DESCRIPTION
3.1
AQUAIR S is a “water to air” heat exchanger unit with a heat output of 10, 16 and 20 kW (assuming
a hot water supply at 80 ˚C is available). It is supplied as a downflow unit but it is also suitable for
upflow installations. When used in upflow installations an “air vent” (see 9.6.2) must be fitted to
the heat exchanger. Modairflow control is incorporated. A wire mesh filter is fitted as standard.
The unit requires a supply of hot water at a minimum temp. of 60 °C. Water connections are left
or right handed through knockouts in the sides of the cabinet.
3.2
The air is drawn in through the air filter or Cleanflow air cleaner (if fitted) and the heat exchanger
by a centrifugal fan, and it is discharged through the opposite end of the unit. A Summer Air
Circulation switch (optional) allows the facility to supply unheated air to the air outlets during warm
weather. An external timer (not provided) will be required if it is necessary to set the periods of
operation.
3.3
The Aquair S unit has been designed to allow downflow and upflow configurations. It also allows
the airflow to be redirected through the side of the unit via a Side Return Air kit.
