f Only connect energy efficient circulation pumps ap- f
proved by us.
If energy efficient circulation pumps are used that have
not been approved by us, use a relay with a breaking ca-
pacity of at least 10 A/250 V AC or our WPM-RBS relay set.

12. Fitting casing components
Sealing the appliance
Before fitting the casing parts, seal the appliance by affixing plas-
tic sheets. The plastic sheets are supplied with the casing parts.
f Use fabric tape to affix the sheets over the holes at the bot- f
tom of the frame on the r.h. and l.h. sides. The fabric tape is
supplied with the "air hose" accessories.
f Hang the side sheets with the pre-cut holes onto the hooks f
on the appliance.
