(Use polyethylene foam as insulating material.)Piping and drain hose forming1. Die-cutting front panel slitCut out the slit on the leftward or right side of the front panel for the leftor right connection and the slit on the bottom left or right side of the frontpanel for the bottom left or right connection with a pair of nippers.How to remove the drain capClip the drain cap by needle-nosepliers and pull out.How to remove the drain hose• The drain hose can be removed by removing thescrew securing the drain hose and then pulling outthe drain hose.• When removing the drain hose, be careful of anysharp edges of steel plate.
