INSTALLATION INSTRUCTIONS
Hard Start Kits for 14-SEER Side
Discharge ODU
When inconsistent compressor starts are found, it is an
approved fix to add a locally sourced "Hard Start" kit. A kit
must include a capacitor and a relay. Replacing the OEM
capacitor with one that has a higher micro-fared rating IS
NOT an authorized repair and will void the warranty of the
product.
Selecting the Correct Kit
Hard start kits are sized by compressor horsepower (HP).
Use the chart below

Installing Kit
The hard start kit must be installed in parallel with the
compressor capacitor. To do this, connect the leads from
the kit to either side of the compressor capacitor. The
kit must also be secured to the chassis of the unit, and if
required, grounded.

Fine Tuning
1. Allow the system to operate for at least 20 minutes
before checking refrigerant temperature and pressure.
2. Perform an air flow calculation to ensure the blower
is delivering the correct volume of air at the pressure
intended for the distribution system.
3. When the above are completed, verify that the
operating temperature and pressure comply with the
chart.
NOTE: "IDT" = Indoor Temperature
"ODT" = Outdoor Temperature
1. Remove refrigerant if the pressure is above the chart
value.
2. Add refrigerant if the pressure is below the chart value.
Perform an inspection of the entire installation and
finalize any items needed for completion. Review the
system operation, thermostat functions, and warranty
policy with the owner.
Leave this manual at the jobsite for future reference.
