Common questions

Why is my Daikin unit flashing its indicator light in Killarney?

A flashing operation lamp means the board has logged a fault code. Pressing the cancel button on the remote and holding it cycles the code out; U0 points to a low charge, U4 to a communication fault between indoor and outdoor units, and A5 to a freeze or high pressure trip.

Why is my pool heat pump tripping on flow error?

Nine times out of ten it is a partially blocked filter, a closed valve or a failing flow switch. Water flow through the exchanger is checked before any refrigerant work is considered.

Can you work after trading hours?

Yes. Retail, restaurant and office work is routinely scheduled at night or early morning under a permit-to-work so trading is not interrupted.
