Question about Dishwashers

Open Question

I need an installation/user guide for a Comenda C95Z commercial dishwasher. Electrician needs to know if it can run on single phase (it came with a 3 phase lead). There are hot and cold water hoses - plumber isn't sure what the cold is for as it doesnt have a connector attached. Is there anywhere I can download the manual?

SOURCE: Need to convert 3 phase Hobart dishwasher to single phase

It will not be inexpensive to convert your dishmachine over to three phase. With everything that you will need to replace, depending on the model if converyor or not it may run close to what it costs to have 3phase run to the building that you plan to move into.

Single phase or 3 phase

Hmmm. Good question. Like anything, it varies depending on how the equipment is going to be used and in what environment. We could really get into the weeds, but let's just ask the couple of key questions.

1. Is this a commercial or residential environment?
2. What's the horsepower of the motor(s) in use?
3. What's the availability of 3 phase power?

1. If your saw is in daily, commercial use, then 3 phase may offer some distinct advantages: While it's expensive to convert (assuming you don't already have 3 phase available) it allows for smaller, less expensive wiring, and lower voltages making it safer and less expensive to run.

Single phase, otoh, is much more available, and runs motors up to 5hp with little difficulty. It does actually cost more to run a lot of single phase equipment so if cost is an issue and you have quite a few motors, this may be a large determining factor.

2. As I mentioned, if you're only running one or a couple smaller motors, up to 5hp, single phase should work just fine. I have several pieces of machinery with 5 hp motors them on single phase 220 and they perform great. I don't recommend 110vAC for motors under significant load. They run too hot and are not all that efficient, as well as under-powered.

3. Installing a 3 phase electrical system can be very expensive. I would look into this carefully, get a few estimates before moving ahead. You'll need to find out if it's even available, cost of transformers for 110 in the building as well as whether they'll charge you commercial rates for your electricity once it's installed.

There is no simple answer for this question, I fear. There are simply too many factors to consider.

This is the short answer. A simple web inquiry will give you more answers than you actually need.

Good luck.

Electric Phases for Hobart Oven

you must understand this : your electric oven must be indicate if it is a single phase( use 3 wires for 230 2 hot wires + 1 Neutral see the diagram like dryer? you must sure about this. Normally any appliance for home are single phase NOT 3 phase.

2) If you electric oven, say 3 PHASES( use 4 WIRES, 3 hot wires+1 Neutral wires) this for industrial application +comercial 270266c5-a0ad-44dc-9f40-e963255d47f5.jpgNOT for home

However if you system is 3 phase you must need to install 3phase transformer.ba1c9d4d-85e3-4744-8ce5-2f25c6e34ad3.jpg

Convert single phase dishwasher to 3 phase

No dice, would need to do a lot of work. Need to change out the pump and the timer, and many of the other components would not be able to be used. I would keep it single phase by adding a transformer and a plug in if you need to have itin a 3 phase poure source area.

I have a brand new IR compressor model 2475N7.5 with a 7.5 hp 460v 3 ph motor. is it possible to convert it to a single phase power supply? or should i just exchange it? ... I ordered it thru Northern Tool...

When you google home made 3 phase converters, you will find many ways to make use of 220v single phase instead, however you are limited as to the hp that the motor will produce. If you spin the motor first then apply 220v, the motor will continue to turn at much reduced hp. You need full power to turn a type 30 pump depending on pulley combination/ setup. Best to return the unit and get one that will run on 220v single phase. It will most likely consume more power to do the same work however it would cost a great deal to install 3 phase. Most likely not even available at all. Many years ago, I worked at Sears and happened to see an electrician coming down from roof access of building. He told me that sears had a 3 phase generator being turned by a 220v single phase motor to run an air conditioning unit. He said that it worked quite well. Does not sound cost effective.

Need to switch 3 phase to single phase

An electrician can provide you with a TRANSFORMER that has a single phase primary and 3-phase secondary. The secondary would connect to your Plasma Cutter. He may be able to find you a used one. Ask him what you need for the size of your Cutter, and you may be able to find it on Ebay.

Using Freud Super Dado set on PM2000, 3hp, single phase saw

Having used a Model 66 Powermatic for 25+ years, many times with a full 3/4" stack dado on the saw, I can't imagine the saw is at fault, unless there is some specific fault with the motor.

Granted, these new dado stacks with their anti-kickback fingers and four teeth per chipper instead of the customary two are heavier, and cause a greater load on the arbor, but it's a balanced load, and bringing it up to speed shouldn't be an issue. Consider the torque involved in ripping through two inches of solid oak, for example. So I would also rule out the dado set. I've seen many saws turn the same set, some running with only 1 1/2 hp and 110v extension cords. (Though I don't recommend this unless you're very patient.)

The three phase connection is worth some investigation, in my mind, as the likely culprit. I used to have a 5hp 3ph motor on my saw, and at the time had a second saw hooked up to the same power feed in the shop. We did what your electrician told you was possible, took a 230 (208) leg off the 3ph power. It's been many years, but it seems to me that the electrician who helped us hook this up at the time warned me that it had to connected in a specific manner, using particular leads, because of the nature of the 3 phase. This has something to do with the lack of a neutral, I believe, but I'm not an electrician. You might consult the following website for some further information regarding the specifics of this type of connection, and reference the following info:
1 Phase Loads on 3 Phase Power
Single-phase loads may be connected to a 3 phase system in two ways. This can be done either by connecting across two live conductors (a phase-to-phase connection), or by connecting between a phase conductor and the system neutral, which is either connected to the center of the Y (star) secondary winding of the supply transformer, or is connected to the center one winding of a delta transformer (High leg Delta system). Single-phase loads should be distributed evenly between the phases of the 3 phase system for efficient use of the supply conductors and supply transformer. Click here to read more about connecting a 1 phase load to a 3 phase power supply line.

If that's more than you wish to digest, I heartily recommend you consult an electrician accustomed to commercial industrial wiring. He ought to be able to take a quick look at the breaker box and the connection to the saw and sort you out.

The only other thing I can think you might be able to check on your own is the wiring configuration of the magnetic switch itself. It is turning off, you say. They must be rewired internally to conform with the particular power supply provided. There should be a wiring diagram inside the switch box or in your documentation that shows how to do this. I can remember changing the leads, and at one point changing the actual thermal breakers, when I moved from one shop to another over the years. That may have been when I had to change the 3ph motor for a 1ph one. If the wiring to the saw is correct, this might be the direction to look.

Short of loose drive belts, I can't think of anything else to offer you as a troubleshooting guide.
Let us know how this works out, and let me know if there's anything more I can do to help!
