Blueridge BMKH12MCC Unit Type:
Ceiling Flush Mount
Ceiling Cassettes flush mount in the ceiling for better
air distribution and to preserve the appearance of your
walls. Ideal for drop ceilings, more construction is required
to retrofit this to a standard ceiling, involving removal
of ceiling material and some reframing.
Blueridge BMKH18M-LM Unit Type:
Wall Unit
Wall mounted units mount high on a vertical wall. The
connective hoses and condensation go through the wall
to the outside behind the unit. These are the most
popular design due to the ease of installation and
low cost.
Installation
Step 1
Mount
Once you have received the product, mount the indoor and outdoor units to your desired resting location.
Step 2
Connect
Next, run the line sets, drain line, and electrical wires from the indoor unit(s) to the outdoor unit.
Step 3
Electrical
Run a 220 volt power circuit from your main breaker to the outdoor disconnect. Then run the electrical whip from the disconnect to the outdoor unit.
Step 4
Pro Start Up
We'll help you get an HVAC contractor who will pressure test the line sets, check for leaks, and release refrigerant. Click Here For Details
