hi
i am having an intermitting prob with the circuit on a tecnair downflow!!!
every couple of weeks the evaporator ices up restricting flow causing high room tev,when i arrive to site the tev main boby is iced up also.
the external equalise line is frosted a little near the compressor side but nothing towards tev.
i noticed from previous threads that the power head must be warmer than the bulb to prevent mop..
this is a comms room with a 20 degree setpoint!!!
is there a good way to test these, as when a normal tev goes, it goes!!
i am thinking moisture also..
any thoughts ??
