Assembly instructions for systems with 2 collectors:
Models: 150-2-S150, 200-2-S200, 300-2-S200, 300-2-S230
Assembly steps:
6.1. Open the pack of the support system. Identify the items from table (page 5) and the drawing next
page.
6.2 Assembly the parts between themselves using the set of bolts and nuts included in the pack. At this
stage do not fasten tight the bolts.
6.3. Fix collectors on support as shown on drawing using M6X20 bolts and washers (No 22 &23 at table)
Do not fasten tight yet.
6.4. Position the tank on supports. Two people for 200 ltr and four people for 300 ltr are needed to handle
it from each end. Fasten well with the 2 bolts M10X30 the tank on the support system. (The 2 bolts
are already mounted on the tank and have to be temporarily removed before placing the tank on the
support).
6.5. Now, fasten well the collectors on support and then fasten well all the parts of the support system
among themselves.
6.6. Drill the “floor” with 10mm drill at the 4 fixing points, insert the raw-plugs provided, and fasten well the
whole support system to the “floor”. Make sure that the material of “floor” is suitable (concrete) for this
kind of fixing, in order to withstand up to 97,2 Km/hr wind speed. If in doubt, consult your supplier, or
your engineer for possible alternative way of fixing.
6.7. Connect the insulated copper (or plastic) pipe at closed loop system. The long pipe is for cold return
to bottom of collector. The short pipe is for hot supply from top of collector. Make sure that you fasten
well the “compression” fittings in order to tight the closed loop. Fix and fasten well the 2 compression
end caps on the 2 remaining open ends of the collectors.
6.8 Connect the non-return pressure safety valve on the cold water inlet of boiler making sure that the
arrow is pointing towards the tank (upwards) and the escape outlet is facing sideways parallel to the
tank, in order to prevent harm or burning during steam escape.
6.9 Connect cold water supply using always a shut-off water valve. (Make sure the pipes are well
insulated).
6.10 Connect hot water outlet piping to consumption points. It is strongly recommended to install a
thermostatic mixing valve set at 50-55
o
C on the hot water piping anywhere before the consumption
points. (Make sure the pipes are well insulated).
6.11 Fill the tank with cold water. Leave open one “tap” of hot water, so that air will be flushed out and the
tank will be completely filled up.
6.12 Fill up the closed loop system with thermo-convention liquid from the top pipe (point 15). Make sure
that no air-bubbles are coming out so filling is completed.
6.13 Screw the bronze cap with the copper ring on the filling point to seal the closed loop system. The
closed loop is permanently sealed.
6.14 Check for leakages on open or closed loop system.
6.15 The (optional) electric heater should be connected by a fully licensed electrician following the national
standards for electric installations.
