8.0 Water Connection
Before making the pipework connections refer to Section 3 for advice on System Design.
Note: For ease of installation the pipe connections are included with valve kit (see Section 15).
Connect the unit to the flow 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 G3/4”.
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 flow 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.
