Finally the covers of service valve and electrical parts on the evaporator unit can be opened from the front but not the side? The side open design is so bad

@shaneevans8963 2 года назад

Just recently worked on a WIF with a similar set up, 1.5 years old. A company installed it and never changed the refrigerant on the board. Had to do a ton of de icing, the line set was around 120' and still flooding back. Nice video. It had 448 in it but the board from factory is set up with 404.

@MikeB9771 2 года назад

Nice thorough video, I am starting to see a lot more of the Russels. Darn good time to jump in the market. The need for new equipment far exceeds brand loyalty. Good video.

@HVACRSurvival 2 года назад

I was impressed, other than the non-serviceable EXV valve. The heatcraft valve can be unscrewed and change just the head.

@ErickHernandez93 2 года назад

Yeah they’re fun as they’re pretty much new to what we are used to but i’d be careful & check to be sure they didn’t install it incorrectly or in no time you’ll end up going back to have to find out why it’s freezing up If i can find the pics of both valves i had to reinstall I’ll send them your way

@mainj54 2 года назад

In my area, Health Dept. would ding those bare copper drain lines in cooler. They don't want any exposed copper in boxes including liquid lines. Also can not install them tight to wall, require standoff clamps so lines can be cleaned on backside. Galvanized clamps against copper ?

@HVACRSurvival 2 года назад

I get most of that but why not bare copper pipe in a cooler? I can see that in a freezer.

@mainj54 2 года назад

@@HVACRSurvival Bare copper can develop green corrosion over time and potentially flake off and into food. That is their thinking.

@proc7867 2 года назад

I’ve only had one issue with those controllers. We installed a walk in cooler/freezer combo box and supposedly the right sized equipment was supplied by the same company as its a standard in this franchises (Imperial brown I believe). After a day of runtime and product coming down to temp, the cooler box would overcool and freeze the product. Freezer did not have any issues (it’s meant to freeze, it can run longer obv) The system cooled the box so quickly that the box would be at temperature and continue to drop before the min compressor run time (4 minutes) would be up. I was able to lower min compressor run time to 2 minutes but the problem continued. I even tried adjusting the differential which helped, but didn’t solve the issue completely. That was on OT at 9:30pm and they closed at 10. Another tech was sent back, but not sure how the issues was solved. I would venture a guess to say that the equipment was oversized for the box even though it was all supplied by the same manufacturer. Imperial brown

@HVACRSurvival 2 года назад

All parameters were adjustable and could be set to zero if I remember correctly. I would definitely go with a minimum of 3 to 4° differential

@ErickHernandez93 2 года назад

Worked on a couple of those EEV’s certain companies have installed backwards, they’ll work okay for sometime then come to a point in which they fail & constantly feed refrigerant causing big freeze ups, keep an eye out Rick, be safe brother

@HVACRSurvival 2 года назад

Thanks for the heads up. I noticed the exv was a one piece unit but the heatcraft was a two piece allowing you to replace the driver.

@ErickHernandez93 2 года назад

Yeah they made them like that which is harder for us to replace, poor design from russell unfortunately

@omarfue556 Год назад

Yep, the Sporlan valve is a 1 piece valve. Heatcraft uses Carel valves, which you can separate the stator coil from the valve.

@EverythingHVACR 2 года назад

Well done Rick!

@HVACRSurvival 2 года назад

Thanks bud!

@uxwbill 2 года назад

I am definitely curious how well that control board will hold up in the evaporator, especially as it has a tiny battery on it (just past the upper left corner of the display). I am surprised they didn't put a shield of some kind over the nasty high voltage/power supply part of the board.

@HVACRSurvival 2 года назад

@per995 2 года назад

You have other refrigerant rules than over in EU😬 Since January 2020 it s not allowed to install or refill any 404A GWP over 2500 is banned. Nice job you made😊

@HVACRSurvival 2 года назад

Yeah I know, we're going to be forced into something different before long. We're reluctant to change till we absolutely need to just because we have so many refrigerants already. I suspect we'll probably do R448a like the ice cream machines.

I'm used to HeatCraft too but I do like some features of that Russell. That's display looks so easy to read and work. I always ask if I can handle the wiring because sparky usually makes more work for me. I try to believe it's just ignorance of how that system works and not recklessness

@Artisan.HVACR1 2 года назад

With that EEXV serving as the metering device, it's not surprising that Demand Defrost has been deployed in that system, as opposed to a time-only feature. It would not make sense to use the technology that's needed to support an EEXV, but use a time-only defrost feature with it. However, using time as a default in an EEXV system does make plenty of sense.

@HVACRSurvival 2 года назад

I know how many problems I had on the True freezers that have a accumulated run time style defrost like that. I had to change them all back to time.

@Artisan.HVACR1 2 года назад

@@HVACRSurvival i hear you. What I'm saying is a conventional TXV used with a standard electronic or electromechanical defrost time clock does the job well. But when manufacturers start using electronic TXVs (ETXVs), then they have to use the technology that supports those ETXVs which is not what a conventional defrost time clock or a conventional TXV operates on. Take for example Heatcraft's demand defrost system under their Beacon trademark name. They use demand defrost rather than time-only defrost. To go with demand defrost they have to include solid state sensors strategically placed on the evaporator coil as well as a microprocessor that takes in the signals from those sensors as analog inputs and runs them through an algorithm to determine when to go into ddefrost mode. That's quite a bit of technology to deploy when a standard TXV and standard defrost time clock will do the job just fine. I understand that the higher technology is used because it manages the use of energy better, but sometimes higher technology on these systems is really overengineering them.

@SupremeRuleroftheWorld 2 года назад

can you explain why virutrally nobody in america uses wire ferrules when making connections? as the voltage is half of what it is in the rest of the world the current is double that of our systems you really need to take care of the correct wire connections. lots of videos that i see of hvac repair is rife with burnt wires from poor connections due to a lack of ferrules and no enough force when screwing the wires down.

@HVACRSurvival 2 года назад

Where are you looking for ferrules at? The high voltage coming into the EVAP?

@SupremeRuleroftheWorld 2 года назад

@@HVACRSurvival yes for example. in basically every installation i see bare wires shoved in connectors and barely tightend down wich have all oxidised after just a few years and suffer heat damage. especially on defrost clocks and contactors. and the sensor leads going into the boards on the green terminals. those wires tend to snap off or cause intermittent issues in a humid and viberating machine. even in eurpe i have to teach and force apprenteces into using ferrules and screwdrivers with torque clicks in them. almost everyone does not tighten terminals down enough.

@HVACRSurvival 2 года назад

A feral is usually a piece of plastic or something that keeps the wire from getting skimmed when it goes through a metal connector are we talking about the same thing?

@etherealrose2139 2 года назад

@HVACR Survival it's a termination you put on the end of a wire. Like a ring terminal except it's... just a chunk of tube you crimp on and make it into a kind of solid block. Then you put the ferrule into your connection and that's that. To me, it's a european solution to a question not asked. You twist stranded wire and you can certainly torque down a lug on it just fine. Those little green terminal connection points on PCBs are garbage but I don't see a ferrule fixing that. It is quicker than tinning the strands.

@etherealrose2139 2 года назад

@Supreme Ruler of the World contactors usually use lugs which aren't an issue or you use a spade connector which isn't an issue. A loose connection in any circumstance is a bad connection. A ferrule wouldn't change that.
