How To Put Manitowoc Icemaker In Harvest

Q-1300 series barely harvesting, sometimes non at all. Ice just hangs in that location, and the plate looks good. Remote condenser was cleaned, subcooling about 27-30 degrees at the water ice-maker, before the heat exchanger.Pressures normal, according to the service manual.The Harvest Pressure level Regulator valve frosts upwardly, or at least gets cold, when harvesting water ice, even though it'southward taking gas off the height of the receiver.I'm thinking it'southward either the HPR going bad, or it's grossly over charged.The headmaster on the condenser seems to exist working, equally in it doesn't seem to be bypassing, every bit noted by the subcoolin measurement.Also checked likewise see if the machine was level, and it was.No water valves are leaking past, just incoming water is about 85 degrees F.Not out of spec, but kinda shut. also condenser air incoming temp is about 96 degrees F.Belch temp at the comp is in the 180 deg F range, simply getting downwards to 100 in harvest mode.It'due south a R-404 automobile, and I'grand gonna pull the charge tomorrow, weigh it, and probably change the HPR valve as well as the headmaster. I promise I'm On the correct rails here as Ive simply worked on about eight-10 water ice machines, none were Manitowoc.
Whatever suggestions would be appreciated!!

Activate the thickness stat or micro switch and see if you lot can hear and feel the hot gas valve working. Also is the water hard or soft I.e., a lot of lime calibration on the evap plate if there is the ice sticks to it.

Is the icemaker using a well and pump to circulate the water? If information technology is you could endeavor using cold water from another source, 85 seems very high to me here in england. Had trouble with bactaria build upwardly on ice makers causing poor harvests , due to jets , pumps and filters beingness blocked I utilise miltons or anything that cleans babys bottles. dill. :

Both hot gas valves are energizing and I'm getting about 100 deg F entering the evap plate, which I experience may be not warm enough.
Also the evap plate is very make clean.

I live here in Florida, and the h2o piping is run in the ceiling, which is probably helping to oestrus upwardly the water, just information technology has been like this since information technology was installed. It may cutting downwards production, along with the 95-97 deg F air entering the rooftop condenser, merely I don't think this is the crusade. Also I cleaned up what piddling algae and leaner already.

Hi on that blazon is at that place a button bar in the middle of the Evap plate if so check this

I think the manitowoc is a fantastic automobile and a lot of major companies are changing from scotsman to manatowoc over hear I,ve had the same problem onsmaller units than your type.The fault has always been the gas accuse they advise you to take pressure with guage only every bit the gas lost in your line is enough to cause a fault.The machine will make three atempts and so throw up a fault I volition try and go you a phone number for help as in that location tech line is good.

Regards bernard

I could use the Phone number, thanks.

Every bit far as using a gauge only to check pressures, I understand the reasoning, but this is a remote condenser blazon unit, and uses 12.5 lbs of refrigerant.I don't think checking the pressures with a standard gauge and hose setup would cause the refrigerant to fractionalize very much in this unit.
I'grand leaning more towards the unit being overcharged, or the harvest pressure regulator valve being bad, equally I was getting frost on the tubing straight after information technology going into the compressor.
This valve is supposedly just taking vapor from the top of the receiver, and I don't remember it should be frosting upwards. I would call up that it would merely frost if it was getting liquid refrigerant, and then the harvest pressure regulator would kinda human activity similar a TEV. This is why I'm leaning more towards an overcharge.
I'll discover out soon enough the side by side time I get back there.
Also this is the commencement fourth dimension I've worked on this particular machine, then I have no idea on information technology's history, other than the PC board was changed out 2 months ago.

Damn I'm long-winded, huh?

Yous don't state what belch pressure is during harvest but that pressures are per the manual. The volume y'all need is the Manitowoc Service Technician'due south Handbook for the Q Model water ice machine. It provides operating pressures for water ice-making and harvest cycles for a range of ambients. Harvest belch pressure level must be in the range of 140-200 PSIG for the Q1300 remote at 90F ambience.

Discharge temperature volition not assistance yous, you must have discharge pressures correct, per the manual, for the given ambient or your harvest will be likewise slow. I have had to replace a couple of HPR valves since they stopped using Sporlan valves. Interestingly, the replacements they transport out are Sporlan.

In that location is also a trouble-shooting department that allows you to clarify system performance. I accept found information technology helpful in the past.

Good luck,

Hi Guys,
Manitowoc ice machines are OK until they get wrong and so effort getting parts.

UK source for parts is Cross Refrigeration in Republic of ireland. Nothing standard, even condenser fan motors are OEM as universals don't fit on the brackets.
For my money y'all cannot beat a Scotsman, parts avilable same twenty-four hours most Ipswich.Best technical helpline i take always phoned and fairly straighforward.
Phillips/whirlpool machines are also very easy to work on and parts readily available from NRS

Every bit with all machines they need a filter/softener on them as limescale shortly screws things upwards on them.

Regards

Fatboy

If you contact Manitowoc past phone ask for Randy DeBauch. He is terrific tech rep and prissy fellow. His e-mail is rdebauch@manitowocice.com
He answerers you actually fast

Silly simple question: Is the car level? the angled lower edge of each 'cup' allows the ice to sideslip off the evaporator and if the machine is leaning to the rear fifty-fifty a piddling bit it can compromise harvest times.

Is the water drape on the machine ?

It volition not go in to harvest with the curtain removed.

So...Information technology'southward been 5 months, making water ice however?

I am having a similar problem only my unit, Series 100 is freezing up and volition non drop the ice. Does anyone know where to get a transmission for this serial 100?

E-mail is woodykirby@comcast.net.
Cheers

Get to the Manitowoc website. Download service manuals.
Their trouble shooting section has always worked for me ( with a picayune imagination). I accept worked on 30-40 Manitowocs' and take e'er been able to solve the problems.....Good luck

sounds like the thinkness stat is faultly
( serious 100)

Worked with almost every ice maker out there. I am partial to Manitowoc units because they put engineering idea into improvements and there is room to get to what you demand to. Check time out of lath and verify you are getting full harvest time. Had problem with short cycle . Changed board and that'southward that. Likewise, fact. back up is one of the all-time in the business concern. Just accept ALL THE INFO they desire when you phone call. The checklist is in tech volume or online. Their time is valuable to them and don't similar to waste matter it. FEISTY

endeavour this ... I guarantee it volition piece of work

clean the automobile well , and so turn it off let it dry, and and so spray it with not stick cooking spray like PAM or similar.
flip the switch to ice
get-go 2 ice making cycles --throw them away -- after that ice machine will make ice and harvest like new--believe me it works

well never listen virtually the guarantee lol
merely it worked for me
let me know how it works for you!

Whatsoever suggestions would exist appreciated!!

yous already checked the hot gas valve? for my evaluation perchance the diameter of hot gas valve getting small if the new hot gas valve blueprint is 42 bar the valve bore of valve is enough to entering.the hot gas it should 90 to 110 psi if lower than 90 in that location will accept a problem in deforsting

If yous head and suction force per unit area are lower that published in the tech hand volume, replaced the HPR solenoid and HPR valve. It is not the headmaster and in temps to a higher place 70F ambient exterior it is non the headmaster.

Troy,
Assuming you verified the charge, and you accept the tech handbook and suction pressure at end of freeze is per the lowest value for end of freeze. Yor headmaster will hot bypass in ambients to a higher place 70F unless the condender whorl is getting wet. With that said expect at your harvest pressures. In harvest they should be college that everyman numbers listed for harvest. If they are both lower your suspicion of the HPR valve not working is correct. But if the head is higher than published and suction is lower that published you have one of the hot gas valves not opening all the way. Both outlet could still be hot but watch how the melting is. You lot have two refrigeration circuits on that evap left and correct only similar the TX valves.

thanks, information technology really worked. the water ice savage.

Can everyone help me ? I have a fairly new Manitowoc Ice Maker South series cubed Ice version.

I moved it to another location, now when I plough it on it goes through the cycles but the water in the tray just gets warm !

Whatsoever Ideas ??

Thanks for your help .

Sounds like you forgot to put refrigerant in. Lol.

Sad couldn't resist.

This thread is from 2004. You lot might have improve luck if yous start a new thread with this issue.
