⚠Important: R404A is a zeotropic blend intended for qualified professionals. Charge from the cylinder in liquid form, never mix refrigerants and do not treat R404A as a universal drop-in replacement.
Is R404A a universal replacement refrigerant?
No. Use R404A only in equipment designed for it or under a documented manufacturer-approved retrofit procedure. Components, lubricant and operating settings must be verified.
Can R404A be mixed with another refrigerant?
No. Mixing refrigerants can create unsafe operating conditions, compromise performance and prevent proper recovery or recycling.
How should R404A be charged?
R404A should be removed from the cylinder and charged in liquid form because it is a zeotropic blend. Use suitable metering practices to prevent liquid damage to the compressor.
Which equipment can use this cylinder?
Equipment whose documentation specifies R404A, plus systems covered by a documented manufacturer-approved R404A retrofit procedure.
Is the 24LB cylinder refillable?
No. This listing is for a factory-sealed disposable cylinder. Handle, transport and dispose of it in accordance with applicable requirements.
Who should install or service R404A?
Service should be performed by a qualified HVAC professional following the SDS, OEM documentation and all licensing, certification and safety requirements applicable to the work location.
