taking Chiller out of storage

[TypicalWhiteAZN]

I built a new system in a room with severely fluctuating temperature. This week's weather has been the worse yet so im putting back in a chiller that I've only used for one summer and has been sitting in storage for years now..

first assessment, i flushed out the coil with a garden hose in which alot of water was still sitting in there. Then i used an air compressor to get the rest out....

Thinking of filling it up with vinegar over night, flushing it tomorrow and setting it up again.. safe?

thoughts? Advice?..

You can never be too safe. Run the vinegar. Worth the extra time. I know I'd hate to have stuff die just because I cut a corner. Good luck!!

How do you Back Flush a chiller?

A: Over time, the titanium heat exchanger will accumulate calcium build up that will impede the cooling process. You may also have particulate matter and debris accumulating on the integrated temperature probe giving inaccurate readings. We recommend Back flushing the chiller every 6 months.

Step 1
Items needed:
a. 5 gallon bucket
b. 3 gallons fresh water
c. 1 gallon of household vinegar
d. Submersible pump
e. Vinly tubing

Step 2
Add 3 gallons of freshwater and 1 gallon of household vinegar into bucket

Step3
Connect vinly tubing to the submersible pump and other end into the “OUT” of the chiller. Connect vinly tubing to the “IN” of the chiller and place back into the 5 gallon bucket.

Step 4
Let the pump run through the chiller for 1 hour in the opposite direction. This will help clean the temperature probe as it is located on the “IN” of the chiller

Step 5
Turn off submersible pump after 1 hour, and discard liquid inside the bucket. Refill the bucket with 4 gallons of fresh water and run the submersible pump for another 30 minutes to remove any
residual vinegar from the chiller.

Step 6
Reconnect chiller to original set up and re-program the set point back to your desired setting
