Great vacuum quiz! Really good summary of important concepts. While I missed 3, I understand and agree why I did on 2 of them, but do not understand the following question. Why is “Register No Vacuum” wrong and “Register Vacuum” correct? I’ve used Fieldpiece and Supco and, when slight refrigerant pressure is applied to break vacumm, the vac gauge display of the system micron level is lost and shows Atmospheric. Thanks.
1. Exposing a typical vacuum gauge to refrigerant vapor will make the gauge?
Fail
Creep Up
Register No Vacuum (my answer)
Register Vacuum (quiz correct answer)
Into a Paperweight
I run my vacuum to 150-200 microns if it fluctuates up and down during pull down moisture it it didn’t drop below 300 leaks then you have your trapped refrigerant in oil time
How can #3 be all the above when all the answers are below?
Did poorly on the test but I don’t work in the trade, I have an AS degree in HVAC, 608 Type 1 & 2 certified, but circumstances out of my control lead me down another path . I came across your podcast a week ago and can’t thank you enough for the info you are putting out. You are doing a great service and great job!
VENOM PACK CONDENSER
PURE CONCENTRATE COIL CLEANER
Venom Pack Condenser Cleaner is a high foaming pure concentrate liquid designed to tackle the toughest soils. The proprietary blend of specialty detergents will liquify heavily embedded grease and grime to restore heat transfer and increase the efficiency of the coil.
Viper Condensate Pan and Drain Treatment is a sprayable gel. It coats the pan, p-trap and drain piping with a lubricative film to improve flow and prevent future soil adhesion. The slow dissolving enzyme gel will outperform and outlast conventional tablets and strips.
One drop of Nylog on your rubber hose gaskets prior to attaching your core tools, hoses or vacuum gauge will assure that things do not bind or leak during evacuation. Derived from refrigeration grade lubricants. Non-hardening, non-drying fluid which bonds tenaciously to many different substrates. Typically, one drop of Nylog can be stretched about three feet before breaking.

Missed 1, guess I’m still only a monkey with a wrench
I’m getting a “no answer to verification question” dialog box when submitting the answers
