20 Most Recent Hatco Corporation Compact Electric Booster Water Heater - 18in W x 24in D x 12in H - 208V - 3 Questions & Answers

I beleive that would be fine.the only reason phase would make a difference is if it had a motor in it.If you hook up a three phase mtr and it runs clockwise to make it run counterclockwise all you have to do is switch two of the three legs.If you hook it up 123 ,132,213 it will be fine. just make sure connections are tight and you have a ground.

that is in the control cicut the contactor might be bad and taking out cntrl fuse.unhook contactor control voltage by unplugging from contactor tape off the two wires put new fuse in turn on power if fuse does not blow replace contactor.if it does blow you will have to isolate the next thing in the control circut maybe the light.you can buy resetable 1amp circut breakers at grainger for test purposes.sometimes on people I know I will wire in those breakers for them no more buying fuses.

Thanks for your reply. The order in which you connect the wires 1-2-3 does not matter, all three terminal block screws will accept any one of the hot wires from the breaker, one hot wire per each terminal screw.

No. You have to find out if you have 3 phase or single phase power. If this is a new unit you will find a wiring diagram inside the front cover. 3 phase power has 3 "hot" wires. Single phase has 2 "hot" wires. There is a big difference when you hook it up wrong. I don't know if this is a new installation or if you are replacing an old one. The terminals are numbered for 3 phase. If you look in your breaker box, 3 phase 208 will haven a breaker with 3 spaces hooked together by one bar. Single phase will have two spaces hooked together by a bar. So if the breaker kicks out it will flip all 3 space on 3 phase or 2 spaces on single phase. If you already have wires to the location of the booster heater, you may have to use single phase if that is all that is at that location. If you have single phase power you will have to look at the wiring diagram and you will see the terminal block represented for both single and 3 phase. Normally running from the terminal block will be six wires marked 1 through 6. The wireing diagram will say something like "for single phase put 1,3,5 on terminal 1 and 2,4,6 on terminal 3. Leave terminal 2 out all together. Of course at this point your 2 hot wires will go to terminal 1 and 3. There are other considerations as well. With 3 phase the circuit wires will be smaller gauge and may not carry the current you need for single phase. This is a booster heater. You need to hook up your hot water line to go into the heater and the boosted hot water to your appliance. It will not work to heat your water for other purposes. It is meant to take 140 degree water and boost it to 190 degrees. Good luck, hope this helps

hi my name is mark. hi limit safety has a red reset button follow link to instructions to adjust rinse temp to dishmachine. i hope you are not using this unit as a home water heater. http://www.hatcocorp.com/productinfo.nsf/AllDocumentationAttachments/14B2C666CC6F114286257107005AC28E/$File/EBOOSTERM-0406.pdf?OpenElement

Try Rick at Restaurant Parts and More in Ohio. Have model and serial number. He's pretty good at getting stuff like that and he reasonable on prices. I'm in Ga. and I have a 3 day turn around on anything I order from him. He's a straight shooter too. If he can't help you he'll try to find some one who can.

I think it is doing what it was designed to do. I think the water should not get to 170 degrees.
Is this a residential water heater?

I am not sure they are available to non Hitachi service centres. https://documentation.hitachiaircon.com/glb/en/pac/rua-at3s

Cannot find the fault code . There are vidoes on u tube saying how to reset thr code By pressing the reset button . If this does not work youcan ccontact vaillent on there web page . I have a mate who works for them i will ask him as well

Do I need to insulate this heater out in the shed? Freezing temperatures

Call a engineer

The P8 fault can mean many things when it pops up on your Mitsubishi Electric wall controller. The P8 fault is activated when the indoor coil sensor does not change the temperature for a set amount of time after the compressor is (or should be) switched on.

Where does the tube sensor go

call plumber to replace gas valve, it may cheaper replace water heater. gas valve is not DIY

test for sticking relay faulty circuit board or faulty stat
