3-3 Testing
After air handling unit is installed, please pay attention to condensate water problem when starting-up air conditioning
system at the first time. Condensate water is caused because surface temperature of unit is lower than dew point temperature of
environment. Considering such special characteristics of this system, you can cool water temperature slowly so as to avoid
moist air entering air conditioning room, and then avoid the production of condensate water in colder parts of unit. Use
automatic flow switch to avoid the production of condensate water. If the system isn’t installed automatic flow switch and
thermostat, fan runs unstably, or inlet/outlet pipe valve of coil is not tight when it doesn’t work, you should startup air handling
unit carefully so as to avoid the production of condensate water.
Fan
Put on the switch, the fan will be driven. It should run continuously. Switch off fan and it would stop running in time. Pay
attention to the rotating direction of fan when it runs.
3-4 Running
Fan
Put on the switch of the fan to control its running. The fan would run continuously. When you shut off fan, it will stop
running in time.
Exhaust the Air in the cooling coil
There is a discharge valve on the outlet pipe of coil. When coil is watered at the second time, there will be some air
collecting in coil. The part air will be collected in the tiptop of coil under the function of water in generally. If there is bubble
in coil, there is air in it. So you need to open the discharge valve to exhaust air so as to guarantee the heat exchange efficiency.
After air is exhausted, you should close the discharge valve to avoid chilled water leakage. If you do not follow
above-mentioned safety regulation to operate, manufacturer will not be responsible for any accident caused by that.
