Check the header tank level, clean out if necessary, add inhibitor and fill if system is empty.

check any valve on feed pipe is open

Check for any leaks on what you have done if unable to use test pump.

Bleed cylinder coil if a bleed point is fitted

Bleed all rads and bleed points

Check inhibitor levels (test strips etc)

Test operation of any motorised valves and the controller to make sure it is working correctly.

Turn on boiler and check rads for balancing (use 2 clip on thermometers and should be about 12 degrees C difference between flow and return)

Check boiler stat

Check setting of room stat

Check cylinder stat (should be 65 degrees C)

Bleed again after a few hours (with pump turned off) and check inhibitor level again.
