Answer

The cycle time is 2 minutes longer than usual

Answer

The rinse water temperature is 1°C below the set point

Answer

The door seal shows minor surface discoloration

Question 3

What is the purpose of running a daily function test or cycle check on an AER?

Accepted Answer

Question 5

How should AER channel adapters and connectors be maintained between uses?

Accepted Answer

Stored dry after being cleaned and disinfected per the AER manufacturer's IFU

Answer

Soaked in high-level disinfectant continuously between uses

Answer

Replaced after every 10 cycles to prevent biofilm buildup

Question 6

What does MRC stand for in the context of AER chemical management?

Accepted Answer

Minimum Required Concentration

Answer

Minimum Reprocessing Concentration

Answer

Maximum Recommended Cycle

Answer

Manufacturer's Recommended Chemical

Question 7

An AER manufacturer states the disinfectant may be reused for a maximum of 14 days. On day 10, an MEC test strip shows the solution is below MEC. What should be done?

Accepted Answer

Discard the solution immediately and recharge the AER with fresh disinfectant

Answer

Continue using the solution since it has 4 days remaining in its use-life

Answer

Add a small amount of concentrate to bring it back above MEC
