This site uses pop-up windows to display each lesson module. If your software is set to block pop-ups, then you will have trouble accessing these resources.

The web browser you use (Windows Internet Explorer, Mozilla Firefox, Google Chrome, etc) to access this site determines the different ways that pop-up blockers are used.

Many web browsers have a built-in toolbar with pop-up blocker options, including Internet Explorer, or FireFox. You may also have other toolbars installed (such as Google or Yahoo Toolbar) or other pop-up blocker software installed on your computer.

To avoid problems, consider this a trusted site, and therefore set your system to allow pop-ups.

To adjust the pop-up blocker settings on Internet Explorer 7, click Tools, Pop-up Blocker, and then Pop-up Blocker Settings if you see a small window appear at the top of your browser with the message "Pop-up blocked. To see this pop-up or additional options click here...,", click on the link, then click on the message and select the option "Always allow pop-ups from this site."

If you use another web browser, the Help section of your blocking software will tell you how to allow pop-ups. If your firewall or security software covers a network instead of just your computer, consult your Network Administrator for assistance.

The HVAC Contractor has always been able to weigh in the correct charge to compensate for the extra length of the liquid line when it is below 55 degrees outside. This however was not a verification procedure for the rater. The rater always had to wait for the outdoor conditions to be above 55 degrees outside and the inside temperature to be above 70 degrees before testing could start. This has caused many a rater, in the colder climates, to not be able to close permits in the winter. At one point there was a procedure being considered by the California Energy Commission allow the rater to control the discharge air volume from the condenser to raise the head pressure and thereby be able to perform the test in under 55 degree conditions. This idea was scrubbed when they could not get any manufacturers to buy into this concept due to the possibility of damage to the compressor on initial startup in cold weather. There is now direction from the CEC to have the cities allow a conditional closure of permit to allow the raters to come back when it is above 55 degrees outside. This whole issue has now gone on the back burner because it will not be an issue for the next six months. It will then rear its ugly head again next winter. I think the CEC is hoping someone will come up with a Charge Indicator Display to meet their requirements and everyone will adopt them and they will not have to deal with cold weather testing issue. This is just another example of not thinking the process through all the way before mandating a certain way of doing things without being aware of the ramifications.
