Ingersoll Rand Ingersoll Rand Refrigarated Air Dryer TS12A TS12A

All air pressure is fully discharged and isolated from the system.

The machine cannot be started accidentally or otherwise, by posting warning signs and/or fitting appropriate anti–start devices.

All residual electrical power sources (mains and battery) are isolated.

Anyone entering the machine is aware of the reduced level of protection and the additional hazards, including hot surfaces and intermittently moving parts.

The refrigeration is recovered by a qualified technician with the appropriate certifications to handle refrigerants.

The appropriate fire control and oil spill equipment is available.

The work carried out is limited to only those tasks which require the machine to run.

Appropriate personal protective equipment is worn.

Warning: This procedure should only be performed by a qualified refrigeration technician.

Dryer loaded with a minimum of 80% of full compressed air rated load?

Dryer parameters stabilized (30 minutes with no changes in conditions)?

Refrigerant gauge reading from low side Schrader connection

Wall temperature reading from thermocouple or similar device

Allow dyer to stabilize (30 minutes with no changes in conditions) after adjustment before checking evaporated superheat.

Checked setting on each evaporator and thermal expansion valve before making adjustments?

NOTICE! Do not adjust the low pressure below 5.03 barg (73 psig) or above 5.66 barg (82 psig).
