right hand horizontal installation
left hand horizontal installation
Important Note
Where a left hand horizontal installation is to be
made, then the removable inspection plate carrying
the secondary connections must be rotated
through 180° from its original position so that the
connection marked cold water inlet is at the top.
The hot water outlet must then be connected
to the top connection and the cold feed to the
bottom connection.
Where an electric immersion heater is to be
used on a L/H installation then a L/H immersion
heater must be ordered (to special order).
When making a horizontal installation (r/h or
l/h) the control panel must always face to the side
and primary flow and return connections must
always be at top dead centre and bottom dead
centre respectively.
When installing a Gemini calorifier in a horizontal plane it is necessary to reverse the cold inlet and hot
outlet secondary connections.

Important Note
Any Gemini HSC
calorifier that is installed
in the horizontal plane
MUST only be
connected to an open
vented system. It is not
permitted to install a
horizontally mounted
unit to an unvented hot
water system.
