LO-LINE RC & LO-LINE RC Heater/Cooler
7.0 Water Connections
l Connect unit to system flow and return pipes. It is
recommended that two
1
/
2
inch isolating valves are fitted. This
will enable isolation of the unit for maintenance activities.
Note: To ensure effective venting of the heat exchanger the
supply pipe should be connected to the bottom connection of
the heat exchanger.
Note: For LO-LINE installations pipe-work must not be routed
directly underneath the unit as this will adversely affect the
operation of the integral room thermostat. If this cannot be
avoided, the pipe-work must be boxed to prevent heat rise.
l Ensure system is flushed in accordance with recognised best
practice and a suitable inhibitor is added to the system as
necessary.
l Open valves fully, check pipe connections for leaks and vent
the heat exchanger - see Commissioning Procedure.
LO-LINE Heater/Cooler installations with chilled water will
require provision for condensate disposal in accordance with any
local regulations.
A drain tray is fitted for condensate collection within the unit.
This should be connected to a 15mm drain pipe.
Note: External pipe-work 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 supply and return pipes is made, any exposed internal
1
/
2
inch pipework and isolating valves must be insulated.
