325
only intended to bear the weight of the unit other than the outside force of the duct, water pipe
and others.
(6) The length of the duct shall be compatible with the rated static pressure, otherwise the unit
would fail to run properly. The inlet and outlet of the duct shall be attached with flexible
connections.
(7) Water pipes shall be cleaned up prior to installation, and the outlet shall be equipped with a
filter to prevent valves from being clogged by foreign matters.
(8) The unit shall be protected again dust during installation.
(9) A filter shall be installed at the return air inlet and be cleaned frequently to guarantee the
expected heat exchange efficiency.
(10) The duct shall comply with requirements stated below.
1) The duct shall be designed and installed as per the applicable local standards.
2) The duct shall be designed so that its sectional area won't change suddenly and the air
direction won't change at the outlet.
3) The duct shall be insulated reliably to prevent sweating under the cooling operation.
(11) Water pipes shall comply with requirements stated below.
(12) The drain pipe and inlet/outlet pipe shall be with the standard threaded pipe fittings. Water

1) The inlet/outlet pipe shall be installed in accordance with the applicable labels and equipped
68 284
with the quakeproof flexible connections and movable joints, as well as suitable filters
68 284
to prevent the heat exchanger from scaling which then would lower the heat exchange
68 284
efficiency.
