Yong Heng fan direction ?

[7MMMARK]

Hello can anyone tell me which direction the fan is supposed to blow air ? On mine the fan is sucking air into the unit. I cant feel much air exiting anywhere ?  thanks  Mark

Sounds right.
Mine draws in. Then blows out across the cooling fins of the cylinder.

Shoebox FYI:

After some temp. readings with the cover on and off,... it stays cooler with the cover on. Fan blows in, across pump and out the motor unit. The other tip that I am sure most everyone is aware of,... clip that tab of metal under the bleed off knob. That way you can remove the cover with removing the knob.
