  • Where can I find installation manuals for QwikPad products?

    Installation manuals, load tables, and up-to-date engineering documentation for the QwikPad can be found at www.qwik.com/qwikpad4gen for generators or www.qwik.com/qwikpad4cond for condensers.

  • How do I contact technical support for QwikSwap boards?

    You can call Mainstream Engineering for technical support at 1-800-866-3550 or via email at info@qwik.com.

  • What should I do if my QwikSwap X1 or X3 will not turn off?

    Connecting the R terminal activates a 3-minute delay. If your blower control board in the air handler has an additional delay, you can disable the QwikSwap delay by installing the jumper on the two-pin header next to the R terminal.

  • How do I use the QwikCheck Acid Test Kit?

    Insert the valve core depressor into the vapor service valve while the system is operating. Allow the vapor to flow for 2 seconds. If the indicator paper changes color to pink or red, acid is present.
