Yes, Qwik System Flush® can be used to flush out a condenser or evaporator coil. If you do not replace the condenser coil after a compressor burnout, it should be flushed. Remember, you should never flush through a TXV, orifice plate, capillary tube, or filter drier because particulates may clog the small orifices in these components. Also, NEVER flush through a compressor …
I tried configuring my QwikSwap® V3 board by setting the Input Mask, but the blower continues to run when it is supposed to be off. Did I do something wrong in setting the Input Mask? I thought I followed the instructions in Appendix A1 (Adjusting the Input Configuration for ECM 2.0 & 2.3 motors only), but the blower motor continues to run.
Before configuring the V3 board, it must be powered up prior to setting any of the configuration switches. To see if the V3 board is powered, look the Yellow STATUS LED located near the center of the V3 board. It should be flashing. Also, ALL the configuration switches to the V3 board should be turned OFF prior to turning any …
I installed my QwikSwap® V3 board to replace an ECM 2 .0 and the blower continues to run when it is not called to. I have verified that there is no delay on break keeping it running. I have waited at least 10 minutes and it is still running. What’s up?
Sometimes there may be multiple commands telling the blower to operate. For example, while the thermostat may not be calling for cooling, a humidistat may be commanding the blower to operate. The QwikSwap® V3 board must be told which commands to ignore, and this is done by setting the Input Mask, which tells the QwikSwap® board the commands to ignore. Instructions for …
Does it matter what location or orientation, I locate the QwikSwap® Board?
You can mount the QwikSwap® board in any practical location inside the air handler where it will be kept dry and secure.
Where do I attach the temperature sensor and why is there no sensor on the X1 board?
The temperature sensor should be connected to the evaporator in a location where both liquid and vapor refrigerant will be flowing so that an accurate saturation temperature can be measured. Typically, one of the bends on a fin-tube evaporator just downstream of the expansion device is an ideal location. This temperature reading is used to optimize the air flow and …
When I remove the connectors from the old defective Variable Air Flow ECM and plug them into the V3 board, there is an extra connector on the V3 board that I have not used. What about that connector?
That is normal. In addition to the 5-pin power connector, the QwikSwap® V3 can accommodate either a 4-wire digital connector (used on ECM 3.0 and Emerson, for example) or a 16-pin connector used on 2.0, 2.3 and 2.5 ECM motors.
What do I do if the connector I took off the ECM motor, does not plug into the QwikSwap® board?
If the connector that is plugged into the ECM motor does not fit on the QwikSwap® board, you are using the wrong QwikSwap®. Constant Torque ECMs are also sometimes referred to as X-13 motors and have a 4-pin connector and 5 individual speed/torque taps, which will only plug into a QwikSwap® X1 or QwikSwap® X3. The X1 will then drive …
Why should I use Qwik System Flush® to clean out a system after a compressor burnout?
When a compressor burns out, highly acidic oil is formed. Although the majority of the oil remains in the compressor (which will be removed and replaced), some oil is always present in the plumbing and remaining components in the system. If you are changing the entire system, including any piping between components in a split system, then there are no …
Why is it necessary to flush the old line sets when converting from R-22 to R-410A?
When retrofitting R-22 systems with the newer R-410A systems, the best practice is to replace all components in the system, including the line sets, to assure residuals do not contaminate the new system. However, situations exist where it is uneconomical to remove line sets, such as when they are recessed inside finished walls, or under concrete foundations and/or slabs. In …
