2.6 Installation of the Water Damper
All units must be equipped with a motorized valve because of the following main reasons.
(1) There would be a water flood risk for some units without motorized valves in the event that they stop
under the cooling conditions.
(2) Under the cooling and heating conditions, energy loss would happen to the chilled water and hot water.
Notes:
(a) The pipe must be wrapped by heat insulation material to prevent condensing water drips.
(b) It is prohibited to bind directly the water valve wire and sponge up with the copper tube, as there would
be probably a short circuit or even electric leakage. The right way is letting the water valve wire go
through the pipe sleeve and then binding the sponge and pipe sleeve.
(c) It is prohibited to put the valve core upside down.
2.7 Electric Wiring

(2) Don't drag the power cord with excessive force.
(3) The unit should be reliably earthed and connected to an exclusive earth device by the professionals.
(4) The air switch must have the functions of magnetic tripping and heat tripping to prevent short circuit
and overload.
(5) The minimum distance between the unit and combustive surface is 1.5m.
(6) The appliance shall be installed in accordance with national wiring regulations.
(7) An all-pole disconnection switch with a contact separation of at least 3mm in all poles should be
connected in fixed wiring.
