2. INSTALLATION
2.1 Health and safety regulations
Handling Operations Regulations 1992 defines
manual handling as: “any transporting or support-
ing of a load (including the lifting, putting down,
pushing, pulling, carrying or moving thereof by
hand or bodily force”. The Regulations set no spe-
cific requirements such as weight limits. However
common sense still has to be used based on an er-
gonomic approach for each individual. The Ecoline
SCE should be transported and stored in a vertical
position.
2.2 Siting the Ecoline SCE
There are few restrictions on the siting of the
OSO Ecoline SCE, however it should not be sited
anywhere open to frost attack. The unit should
be placed on a stable flat surface capable of with-
standing the weight of the cylinder when full (see
table on page 20) and access must be allowed for
maintenance purposes. Prior to positioning the
cylinder, wind out the feet in the base to protrude
by 10 mm (35 mm if using optional wall bracket). If
wall mounted with an OSO wall bracket, the wall
should be capable of withstanding the forces gen-
erated by the weight of the full cylinder. Provision
should also be allowed for the routing of the dis-
charge pipe away from the cylinder to an outside
point according to building regulation G3.
2.3 Component check list
Components supplied with the unit in a separate
accessory kit for site fitting:
•
Expansion vessel with wall bracket
•
Fittings kit
Components factory fitted:
•
Temperature & pressure relief valve
•
Immersion heater(s) - 3 kW
•
Thermostat(s) / thermal cut-out.
Documentation supplied:
•
Installation manual & service logbook
2.4 Supply requirements
An uninterrupted 22 mm cold water mains supply
is recommended, however if only a 15 mm supply is
available, this may be used provided there is suffi-
cient flow rate available. A minimum standing pres-
sure of 2.5 bar and a flow rate of 20 litres per minute
with a 1 bar dynamic pressure is recommended. The
cylinder will operate at lower pressures and flow
rates however the performance will be compro-
mised. The OSO unvented unit is designed for use
with supply pressure up to 12 bar. For pressures
over 12 bar an additional pressure reducing valve
must be fitted in the supply pipe to the unit.
2.5 Expansion vessel
An external expansion vessel is provided to be
connected to the multifunction valve.The vessel(s)
accommodate expanded water when the cylinder
is heated and prevents the cylinder reaching its
maximum working pressure.
2.6 Wall mounting
VB16 wall mounting brackets are available for OSO
unvented units Ecoline SCE 120-180.
2.7 Preliminary wiring
Before final installation and pipe fitting it is rec-
ommended to feed the electrical wires to the
electrical box. The OSO Ecoline SCE is provided
with two channels in the base to feed electrical
cables to the cylinder. The channels run diago-
nally from the front centre to the rear left and
right, and ensures a neat installation with mini-
mum visible cabling.
When the cylinder is moved into position re-
move the electrical box covers. The power cables
should be fed up from the base channels into the
electrical box. When cables are connected they
must be secured using the cable clamp.
All cables should comply with BS6141 table 8 HOFR
85c. Cables should be sufficient length to reach
from the junction box through the base channels
and leave an amount of tail from the front of the
cylinder sufficient to reach the electrical connec-
