8.0 Water Connection
Before making the pipework connections refer to section 3.0 for advice on System Design.
Connect the unit to the supply and return pipes. Pipework can
be routed from the floor or through the wall at the back of the
unit. (See options below). Connections are 3/4"bsp.
Connection directly onto the heat exchanger should be made
using straight connectors so that the pipework can more easily
be routed inside the unit.
For heating only applications the condensate collector mounted
on the chassis below the heat exchanger connections is not
needed and can be removed by unscrewing the two bracket
fixing screws. Removal of this component will aid pipework
fitting when the pipes are routed up from the floor.
For applications involving cooling, the pipework must be routed
to avoid the condensate collector. Connection to the heat
exchanger should be made using straight connectors so that
the pipework can more easily be routed past the condensate
collector.

Pipe Routing Options
2-pipe connection
(The same options are possible for 4-pipe connection)
Note 1:
The supply pipe should be connected to the bottom
connection of the heat exchanger.
Note 2:
Isolating valves are not supplied with this unit, but
should be fitted in case of future service requirements.
The type and size of valves and their location should be suitable
for the application. Valves should be selected in accordance with
system temperature and pressure requirements whilst taking into
account pressure drop characteristics.
Note 3:
External pipework carrying chilled water must be
insulated. Use a suitable sealant as necessary to ensure that
condensate does not spill or leak. Once connection to the
system flow and return pipes is made, any exposed internal
pipework and isolating valves must also be insulated.
