Notes:1 Installation:

Make sure that the control box is installed horizontal, screw nuts positiondownwards.The option boxes (expansion valve and electrical control box) can be installedinside and outside.Do not install the option boxes in or on the outdoor unit.Do not put the option boxes in direct sunlight. Direct sunlight will increase thetemperature inside the option boxes and may reduce its lifetime and influence itsoperation.Choose a flat and strong mounting surface.

2 Service space:Keep enough free for future maintenance.
