wiring is not under stress. Inspect all wiring for insulation
blemishes and damage. Improper wire size may lead
to fire.
• This unit is only compatible with R-410A refrigerant.
Use of any other refrigerant may lead to abnormally high
pressures and may cause damage or injury.

other branches will void warranty.
• Make sure all condensate drain piping is properly trapped
when connected to building drains to avoid drawing foul
gasses into the building envelope.
• Care should be taken to ensure that there are no
refrigerant leaks. R-410A is a heavy gas and will displace
oxygen. Ventilate the area if a leak if found.
