MINI WALL MOUNT SYSTEMS - SPECIFICATION BRIEFS

1. Performance rated for matched system at standard conditions-cooling ID 80/67F, OD 95F; heating ID 70/60F, OD 47/43F. 
    Unit performance varies when weather changes from the standard one.
2. Select equipment capacity sizes per space load calculation schedule and cooling & heating hours. Not to over size or under size equipment.
3. Watch unit operation during extreme weather conditions in summer and winter. Wind baffle helps system cooling & heating performance in 
    low ambient temperatine ranges.

CONNECTION OF WIRES

Panel

Note:

* The environment conditions must be taken into consideration when the connections of power cable are made 
  (such as the ambient temperature, direct exposure to heat exposure to sunlight).

* The specifications for the power cable refer to the minimum values of the metal core wires, taking into 
  consideration the voltage losses, the core wire of power cable must be one size larger than the specifications.

* The grounding wire must be connected to the indoor units and outdoor units.

* The laying of power cables must be done by qualified electricians and comply with the regulations of the local 
  power supply authorities and with the standards of the electric appliance.

* Open the front cover panel.
* Remove screws from electrical box cover and put screws in secured position.
* Remove screws from fastener and put screws in secured position.
* Prepare wires of right size and grade. 
* Recommend to use factory-provided wire/cables.
* Connected to the terminals following wiring diagrams (terminal or color matches).
* Clamp power/control wires to the structure to keep the tension form being transmitted to the wire connection.
* Replace screws or fasteners back to where they were.
