Common questions
What does an E1 or E4 error mean on a Samsung aircon in Sandton CBD?
E1 is a room temperature sensor error and E4 is an evaporator sensor error. Both are usually a failed thermistor or a connector that has corroded on the indoor board, and both are inexpensive parts once the correct one is identified.
What temperature and humidity should a wine cellar hold?
Twelve to fourteen degrees Celsius at 60 to 70 percent relative humidity. Drift outside that band usually means a failed humidistat, a leaking vapour barrier or a unit sized for a smaller cellar.
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.
