This is a safety alert symbol and should never be ignored. When you see this symbol on labels or in manuals, be alert to

the potential for personal injury or death.

Electric shock hazard.

Can cause injury or death. Before attempting

to perform any service or maintenance,

turn the electrical power to unit OFF at

disconnect switch(es). Unit may have

multiple power supplies.

WARNING

As with any mechanical equipment, contact with sharp

sheet metal edges can result in personal injury. Take

care while handling this equipment and wear gloves

and protective clothing.

CAUTION

Improper installation, adjustment, alteration, service

or maintenance can cause property damage, personal

injury or loss of life. Installation and service must be

performed by a licensed professional HVAC installer (or

equivalent), service agency or the gas supplier.

1 Rated in accordance with AHRI standard 270 (2015). AHRI Standard 270 establishes a method of rating outdoor unitary equipment in terms of Sound Power.

2 Rated in accordance with AHRI standard 275 (2010). AHRI Standard 275 provides the calculations for estimating the A-Weighted Sound Pressure at a given distance

from the equipment. That is a more useful number because that is what humans will hear.

3 Based only on distance factor; other factors may change this value such as:

- Unit location (reective surfaces adjacent to the unit)

- Barrier shielding sources

- Sound path/elevation

- Outside noise sources

ACCESSORIES

System Accessory Where Used Kit Number Purpose

Loss of Charge Kit All models 84M23 Protects the compressor if refrigerant charge is too low

Additional System Accessories (indoor section)

TXV Kit

18, 24, 30 H4TXV01

TXVs provide superior refrigerant ow control, comfort and e󰀩ciency compared to

pistons

36, 42, 48 H4TXV02

60 H4TXV03

Outdoor Thermostat - Electric Heat All models 10Z23 Prevents electric heat operation above specic ambient conditions

Outdoor Thermostat - Mounting Box All models 31461 Mounting box for outdoor thermostat

Freezestat All models 93G35 Protects the compressor at low suction pressure conditions

Overow Switch All models 11U75 Turn the system o󰀨, if condensate water overows due to clogged drain pipes
