U-Match Series Cassette Type Unit
1) Install the hoisting stand on the hoisting screw by using nuts and
gaskets at both the upper and lower sides of the hoisting stand. To
prevent the gasket from breaking off, a gasket anchor board can be
helpful.
2) Install the paper template on the unit, and fix the drain pipe at the outlet
vent.
3) Adjust the unit to the best position.
4) Check if the unit is installed horizontally at four directions. If not, the
water pump and the float switch would function improperly and even
lead to water leakage.
5) Remove the gasket anchor board and tighten the nut remained.
6) Remove the paper template.

screw bolts and nuts to secure the unit and make sure the unit stands
erect and level.
(2) Do not install it on top of the building.
(3) If it vibrates and causes noise, please add rubber cushion between the
outdoor unit and the installation base.
(4) When the outdoor unit is in heating or defrosting, it needs to drain water.
When installing the drain pipe, plug the accompanied drainage connector
