Installation
Drainage
The drain fitting is aluminum alloy with a 3/4” BSP male thread. A locknut is supplied to secure to the drain pan. The locknut only requires
hand tightening and then pinching up with a spanner. Do not over tighten or the threads may strip from the nut and also damage the
tray. To fit the drain fitting, remove the drip tray (unscrew the seven screws that secure it), locate the fitting then refit the tray.
A minimum suggested size of drain from the indoor unit is 20mm or 3/4”. This can be either copper or plastic. Flexible hose is not
recommended as it can easily kink causing a blockage and water to back up in the unit.
Important Note:
The evaporator drain pan fitting is supplied loose and must be fitted on site. It is attached to the indoor
unit fan guard with a cable tie. Correct fitting is vital to ensure leak – free operation. The lock nut on the
drain fitting
must be fitted the right way around; otherwise it will not tighten against the drip tray. One
side of the nut has an angled recess – this must be facing towards the drip tray. The fitting does not
require any sealant but a small amount of silicon sealant can be applied between the flared face of the
fitting and the drip tray if so desired.
