Installation
1. Installation preparation
If you need to install the air-conditioner on already existing roof vent, the measure of vent
must reach 14×14 (in). If it is not enough of this measurement, you must extend this
measurement. If it is larger than this measurement, you must make a wood frame for the vent
to meet above measurement.
The gradient of install the platform must no more than 5°. If greater than 5° it can be
influenced that condensation water of the air conditioner could overflow.
You must avoid any wire and any pipeline before incision.
2. Please directly install the top of the air-conditioner on the placket and make windward face
toward the front of the vehicle, condenser toward the back of the vehicle. Put the seal
between air-conditioner and placket, and you can sight the four M10 install bores in the
air-conditioner bottom. To those irregular coarse roofs you must have sealant seal up all gaps
in order to prevent rainwater infiltrating into room.
