Charging
1. Two-stage outdoor units using the Cool Cloud HVAC

unit menus, energize the outdoor unit at 49% ca-
pacity or lower.
b. Charge the outdoor unit as required using the
charging information provided with the outdoor
equipment.
17 Quick Start Guide for Non-Communicating
Outdoor Units
When setting up a ComfortBridge air handler for use
with a Non-Communicating outdoor unit you must set
airflow in the "ton" menu on the PCB or in the CoolCloud
HVAC APP. Failure to do so will result in the air handler
PCB displaying "IdL" and the blower will not operate
with a call for cooling. The Board does not need to be
replaced, you MUST set the airflow first.
EXTREMELY IMPORTANT: For two stage electric heat kit
control the system only needs a single W input. Internal al-
gorithms will control staging automatically based on the sin-
gle W input. For non-communicating outdoor unit wiring, see
instructions below:
1. Use the wiring diagrams on the next page to connect
low voltage thermostat wires.

NOTE: When installing the air handler with a non-com-
municating heat pump, wire directly to the "O" terminal
on the non-communicating heat pump. See the following
figures.
