1.15 CIRCULATION UNIT HYDRAULIC
CONNECTION.
The device is pre-assembled before delivery. The
pipes for connection must be ordered separately.
To avoid any vapour entering the expansion
vessel, position the expansion vessel lower than
the collectors. If the vessel is positioned above
the collectors height, it must be connected by
means of a particular pipe to prevent the vessel
from heating up (this pipe, which is not supplied
by Immergas, interrupts the laminar circulation).
Every time the system is emptied, it must be
rinsed well with running water. The circulation
unit is not designed for use in direct contact with
swimming pool water.
1.16 ASSEMBLY INSTRUCTIONS.
a) remove the device from the insulation casing
by removing the front and rear halves.
b) drill two holes Ø 8 on the wall in correspond-
ence with the holes on the supporting plate.
c) fix the supporting plate to the wall by placing
the rear half of the insulation casing.
d) connect the circulation group fittings in
accordance to the indications of the figures
using the fittings kit supplied separately. If
using copper pipes or pipes of limited physical
resistance their terminals must be reinforced.
The terminal part of the pipe must be cut
perpendicular in respect to the pipe axis and
cleaned.
e) Mount the safety valve unit on the circulation
unit. The safety valve outlet must be connected
to a draining funnel. Otherwise, the manu-
facturer declines any responsibility in case of
flooding if the drain valve cuts in.
f) Connect the electric cable of the circulation
unit as indicated in the respective manual of
the control unit, positioning it at the centre of
the device.
g)Cover the circulation unit with the front case
previously removed.
