115V Mini-Split
Pre-Installation Checklist
1. Unpack and inspect each unit.
2. Check for any damage to the unit.
3. Check the model numbers to ensure a proper match.
4. Check the unit nameplate to ensure the proper electrical requirements will be met.
5. Check the installation locations to ensure the weight of the units can be supported.
6. Check the line set size requirements to ensure the correct refrigerant lines have been run prior to
connection.
7. Check the electrical line requirements to ensure the proper wiring has been run prior to connection.
8. Check the indoor unit for coil leakage. The pressure relief valve on the gas line should release
pressurized nitrogen which ensures the unit has not leaked during shipping.
1. During pump-down, stop the compressor before removing the refrigerant piping. If the compressor
is still running and the stop valve is open during pump-down, air will be sucked in when the
refrigerant piping is removed, causing abnormal pressure in the refrigerant cycle which could lead
to breakage and injury.
2. During installation, attach the refrigerant piping securely before running the compressor. If the
compressor is not attached and the stop valve is open during pump-down, air will be sucked in
when the compressor is run, causing abnormal pressure in the refrigerant cycle which could lead
to breakage and injury.
3. Be sure to establish a ground. Do not ground the unit to a utility pipe, arrester, or telephone
ground. Incomplete ground may cause electrical shock, or fire. A high surge current from lightning
or other sources may cause damage to the air conditioner.
4. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or
similarly qualified persons in order to avoid electrical risk during and after replacement.
CAUTION
1. Do not install the air conditioner in a place where there is danger of exposure to flammable gas
leakage. If gas leaks and builds up around the unit, it may result in fire.
2. After all installation is complete, check to make sure that there is no refrigerant leakage.
3. This appliance is not intended for use by persons with a lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a person
responsible for their safety.
4. Children should be supervised to ensure that they do not play with the appliance.
NOTICE
1. Establish drain piping according to the instructions in this manual. Inadequate piping may cause
flooding.
2. Tighten the flare nut according to the specified method such as with a torque wrench. If the flare
nut is tightened too hard, the flare nut may crack and cause refrigerant leakage.
