EVERFLO STAINLESS uV
uNVENTEd HOT WATER CyLINdERS
STORAGE PRIOR TO INSTALLATION
EVERFLO STAINLESS uV should be stored in its original packaging
in an upright position in an area free from excessive damp.
Regulations G3+L.
HANdLING PROduCT
The EVERFLO STAINLESS uV should be carried upright where
possible. Assessments of risks for carrying the cylinder should
be conducted. use more than 1 person for carrying where
appropriate. Always follow latest guide lines for lifting techniques,
to avoid injury and damage to the product.
WATER SuPPLy
EVERFLO STAINLESS uV operates at 3 bar (controlled by the inlet
control set) and is capable of delivering over 50 litres per minute.
The high quality inlet control set has been designed to make the
most of the flow rates available, however the performance of any
unvented system is only as good as the mains water supply. The
maximum possible water demand should be assessed, taking
into consideration that both hot and cold services are supplied
simultaneously from the mains.
The water supply should be checked to ensure it can meet these
requirements. If necessary, consult the local water company
regarding the likely pressure and flow rate availability.
If measuring the water pressure, note that a high static (no flow)
mains pressure is no guarantee of good flow availability. In a
domestic installation 1.5 bar and 25 l/min. should be regarded as
the minimum. The maximum mains pressure that the inlet control
set can accept is 12 bar.
Consideration should be given to upgrading existing ½” (15mm)
cold mains pipework to a larger size if the recommended
minimum pressure/flow rate is not being achieved.
ELECTRIC SuPPLy
The EVERFLO STAINLESS uV requires 240 Volt electrical supply for
the standard Incoloy immersion elements. The electrical supply
to each immersion heater must be fused at 13A via a double
pole isolating switch to BS 3456. The cable must be at least
2.5mm2 heat resistant (85°C HOFR) sheathed flex complying to BS
6141:1981 Table 8.
