240V water chiller questions


Hello,
My brother just bought a 240V 2 HP chiller from aqua quest and the wires are blue, pink, and green with yellow stripe. I have 2 questions.

1. I wanted to verify that the blue and pink wires go to each of the 120 V legs from the 240 breaker and that the green with yellow stripe is the ground wire. The unit only came with a user manual. I emailed aqua quest, but haven't received a response yet. I attached a pic of the wires. Any feedback is appreciated!

2. The chiller will be outside. Is it best to first run the wires inside, then connect to plug, and then install a receptacle inside that runs to its dedicated breaker? Or is it better to install an outdoor receptacle so if the chiller ever gets moved we won't have to cut the line due to the plug being to big to fit through the hole? (I was thinking it would be more exposed to the elements that way and that the receptacle on the inside would be safer) Or does anyone wire it straight to the breaker line and use the breaker as the switch? This would avoid the need for a receptacle all together but I am not sure if this is kosher for safety.

Any help from the experts is greatly appreciated!

Thanks!

Is this what you have? http://aquaquestonline.com/catalog/i11.html
Is it rated for outdoor operation?

I put a question into aqua quest about that too. Can't find a thing on their website about it. Everything I have read about water chillers is that if they are large, it is not good to put them inside because all the heat goes out the back of them into your room and then you have to spend more loot in A/C to remove the heat from the room. I was thinking on a covered patio, not in direct sunlight and safe from rain, but not indoors. If anyone could help with the wiring question it would be much appreciated!!! Thanks!!!

Your cable would be straight 240. Green and yellow is ground, pink and blue are the two hots. You will need some means to disconnect the cable if this would not be a permanent installation. If it is permanent then use an A/C disconnect box.

This cable uses the same color code as Australia,
The pink is really brown !
Brown is hot,
Blue is neutral,
Green is earth.

But in your case in the USA,
If your mains is 120v,
Brown goes to one hot,
Blue goes to second hot,
Green goes to earth.

The two hots must be different phases,
Not two circuits coming from the same phase.

the green is the unit ground and the others are the hot legs 240V single phase 115V to gound either one.just make sure there is a pump interlock so the chiller shuts down if the pump stops and do not control the chiller with the pump.pressure-trol or flow switch...opens chiller control circuit with no FLOW. whats the chilled water being used for....chiller barrel has to see constant flow during the on cycle
