Page 8 Section 3: Installation
The Grant External Volumiser is supplied with two connections –
one inlet and one outlet. Refer to Figure 2-1.
Each connection is identified on the volumiser casing with an
arrow to indicate which is the inlet and outlet. These connections
are 28mm compression.
GENERAL
In all cases the FLOW connection on the back of the heat pump
is connected to the INLET connection on the top of the external
volumiser, via one of the two flexible hoses supplied with the heat
pump.
The OUTLET connection on the top of the external volumiser is
connected to the flow pipe of the heating system.
One of the two isolating valves, supplied with the heat pump,
should be fitted externally, in the system flow pipe. Refer to Figure
3-7.
The heating system return pipe is connected to the RETURN
connection on the back of the heat pump via the second of the
two flexible hoses supplied with the heat pump.
The second of the two isolating valves, supplied with the heat
pump, should be fitted externally in the system return pipe. Refer
to Figure 3-7.
The actual means of connection between the heat pump, the
external volumiser and the system is slightly different, depending
on which size of heat pump the volumiser is connected to.
Refer to the following details for the model of heat pump being
fitted:
3.7.1 AERONA³ HPID6R32 HEAT PUMP
As the INLET on the top of the external volumiser is higher than
the flow connection on the back of the HPID6R32 heat pump, an
elbow with an integral manual vent must be fitted to the volumiser
inlet to allow the volumiser to be vented of any air. Refer to
Figure 3-8 for the connection arrangement.
For details of the pipe and fittings required to make the connection
between the heat pump and external volumiser refer to Figure
3-9.
