Monobloc Outdoor Unit Installation Manual
•
Insulate all pipework, after testing for leaks, both to reduce thermal leaks and to prevent condensation.
• Wrap the insulations with a demisting screen.
•
If the external unit water pipes are in an area where the ambient temperature is likely to fall below 0°C,
they must be protected against frost (frost protection solution or trace heating).
• The use of different metals on hydraulic piping could generate electrolytic pairs and consequently
corrosion. If necessary install sacrificial anodes or di-electric couplings to eliminate the corrosion between
dissimilar metals.
NOTE:
For units not equipped with a hydronic module a screen filter must be installed. This must be installed on the
water entering pipes close to the unit heat exchanger. It must be located in a position that is easily accessible for
removal and cleaning. The mesh size of the filter must be 1.2 mm.
Please ensure that all water pipework, associated with the heating circuit, is flushed / cleaned before starting the
ESTIA Monobloc system.
The plate heat exchanger can foul up quickly at the initial unit start-up, as it complements the filter function, and
the unit operation will be impaired (reduced water flow rate due to increased pressure drop).
Units with hydronic module are equipped with this type of filter.
Do not introduce any significant static or dynamic pressure into the heat exchange circuit (with regard to the
design operating pressures).
The products that may be added for thermal insulation of the containers during the water piping connection
procedure must be chemically neutral in relation to the materials and coatings to which they are applied. This is
also the case for the products originally supplied by the manufacturer.
