This purge pump periodically expels water from the reservoir to prevent mineral buildup in your window cooler. Unlike other purge mechanisms, this pump operates directly from the cooler’s electronic control system. Unlike typical bleed-off systems, this method is more efficient and uses less water.
How does a swamp cooler purge pump work?
This purge pump periodically expels water from the reservoir to prevent mineral buildup in the cooler. Unlike other purge mechanisms, this pump operates directly from the MCP44’s and MCP59’s electronic control system. Purge systems use much less water than typical bleed-off systems.
How long should I run the pump on my swamp cooler?
You also want to only run the pump for as long as you have water in the reservoir. Running the pump without water will overheat the pump, causing it to burn out.

If it happens occasionally, it just means there’s a little more water in the air conditioner than normal and it’ll equalize.
How does a heat pump work?
To provide heat, a heat pump works by extracting heat from the air outside of your home and transferring it to refrigeration coolant – the coolant is then compressed, which increases the temperature significantly; the coolant is then moved to the indoor unit of the heat pump, which then passes air over the hot coolant, …
Can I use vinegar in my swamp cooler?

Can you use a swamp cooler and AC at the same time?
