Daikin lift pump
Hi,
Just powered up a new FFQ60B and after 10 seconds or so after turning on isolator the familiar sound of the lift pump was constantly coming from the unit, with controller off.
Switched on at controller (brc152d) no fault showed, ran on fan only, high and low speeds and swing worked fine, lift pump still running.
Disconnected lift pump from pcb (X25A) switched back on fan only, ran fine and no noise from pump.
I have left the indoor isolator off but outdoor is powered up to warm crankcase before running when I go back friday to commission.
Just wondering if anyone has had this before on an FFQ, I am guesing the float switch could be stuck or I have a faulty lift pump? Is it fairly easy to get at these?
Cheers
