CAUTION
If the heat exchanger is not used during winter months it must be drained
to prevent frost damage.
NOTE: For Winterising / maintenance - it is recommended that the heat
exchanger is installed with isolation valves on both water input and out-
put sides of the primary and secondary circuits. This will allow the water to
be shut off on both sides and aid removal from the system, when
required.
