f If water (brine) pipe is not maintained periodically, it may affect the operation and may cause noise, maintenance,
and service difficulty.
f Water (Brine) pipe should be insulated and proofed well. If insulation and proofing is not enough, there may be
much heat loss, and also cause frozen damage during winter time.
f When using indoor units such as fain coil two or more, pipe resistance from the product to heat exchanger should
be equal.
f Install the expansion vessel, that can absorb expansion and contraction of water due to temperature change, and
offset the pressure of supply water, at the highest place. Do not install valves between the expansion vessel and
the pipe.
f In case of air inside the pipe cannot be eliminated due to the pipe structure, install automatic air valve at the
highest place among pipes.
f When using expansion vessel or automatic air valve, give 1/250 slant to horizontal pipes.
f Water or brine throughout the product have to be drained by slopes of pipes and first drain valve. If the product is
huge, install drain valves for each main pipes so that draining is easier for winter time maintenance.
f Install water (brine) pump at inlet of water (brine) pipe, and install strainer (over 50 Mesh) which is able to clean
and exchange at pump inlet.
f Use flexible joint at inlet/outlet of water (brine) pipe to prevent vibration.
f Install temperature gauge and pressure gauge at inlet/outlet of water (brine) pipe for checking operation,
maintenance, and service.
