Step 9
Evacuation
Gauges can now be attached to the service ports -
SERVICE PORTS HAVE A 5/16" CONNECTION TO THE GAUGE SET SO AN ADAPTOR IS REQUIRED
Once the gauges are attached the line set can be leak checked using Nitrogen at 300 Psig
Evacuate the unit down to a minimum of 200 Microns, break vacuum with Nitrogen to further leak check
Re-evacuate the system down to 200 Microns or lower
This is an R410A System it is essential that a deep vacuum be pulled on the system to remove all traces of
moisture
Step 10
Main Power Wiring
Electrical Wiring should be done in accordance with all National Electrical
Code (NEC) and local state/city building codes
Tip : Small Electrical Screwdriver is required for unit terminals
Breaker size and wiring must be sized for the rating plate amperage, MCA and MOP
If a smaller than required breaker is used possibility of unit damage etc could occur
Use only HACR type breakers, each system installed must have a separate branch circuit with an individual
breaker/fuse

A local disconnect should be installed adjacent to the Outdoor unit in accordance with National and Local Codes
The Outdoor unit provides power for the Indoor unit, no disconnect is required between the Outdoor and
Indoor units
Line voltage from the disconnect should be wired to
N - L (115V Unit)
L1 - L2 (208/230V Unit)
Remove RHS Knockout on the terminal access panel for whip/wiring connection
Ground connection must be made to the terminal plate
Tip : For easier access to the Terminals in the Outdoor unit remove the lower access panel to install whip and
sealtite connectors for conduit
