Three are 3 limit switches. One for UP limit, One for Down limit,....And....One that bypasses the obstruction signal when closing. This limit switch is set to the height of your photo eyes. Basically (if I understand it correctly)...when the door lowers AND ALSO reaches the level of the photo...

I have a VERY early Wyndstar door. It has an external panel that contains the Photoeye amplifiers, relays etc. Later models have the electronics mounted integral with the motor. Anyway....I had a similar issue when one of the cube relays went bad. This relay is the one that "clicks" when the...

I mix my own.....because of shipping costs. A local chemical supplier sells me a 55 gallon drum of methanol for less than $300. Shipping on the 5 gallons of additive is a LOT cheaper than shipping 55 gallon of methanol....not to mention the hazmat fees. BTW....regarding the reuseable...

I bought a O-Ring repair kit (similar to this on Zoro...

My system already has a "purge" PLC setup. When the temperature goes below 32F, it switches from "non" methanol FB soap to the methanol FB soap automatically. If memory serves me correctly...it "purges" for about 90 seconds....to insure that the winter FB soap makes to to the farthest bay. The...

FWIW....the soap and methanol are pre-mixed. The concentration is what varies depending on the temperature. For years....we've been removing the soap/meth inlet line (1/2") from the eductor...and then changing the screw in tip...depending on the temperature expected. It's messy. Having a...

It was actually seeing the "dual" kit (in a catalog) that gave me the idea. I'm just curious how close the tip needs to be to the eductor in order for the hydrominder to draw in the correct proportion.

Our winter Foam Brush setup uses Methanol for deicing. We have to constantly change the Hydrominder tips depending on the outside air temperature. The colder it is, the more methanol gets pulled into the hydrominder eductor (via a larger tip). We are constantly changing the tips during...

I recommend going to Cardfellow.com . I have no association with them, except that they found me a rate lower than anything I could find myself. Basically, they solicit offers for you....and then they charge the successful bidder (for your account) a small fee. Their service won't cost you...

Parker tells me that (with almost 100% certainty)....that it's NOT the Token acceptor. The acceptor is correctly discriminating, and therefore sending a "pulse". The Hamilton controller is certainly "seeing" the pulse, but NOT giving the proper credit. A call to Hamilton service....tells me...

Parker Slugbuster for BOTH the quarter and Token acceptor. I assume you meant to suspect the Token acceptor and not the coin acceptor.....right?

We use BOTH paper TokenNotes as well as Brass Tokens. One of my ACW4's is intermittently giving a $0.25 credit for a $9 brass token (inserted in the Token slot). What could cause the token credit to give only $0.25 instead of the full token value?

Nope...use the good stuff. I'm going to clean the tank in the next week....and I'll let you know what I find.

The wash opened in 1993. Resin changed in 2011....

Our water is checked for hardness at the start of every day. Typically, we can run 13,000 gallons before the hardness starts edging up. Recently, we've been starting to get hard water at 8,000 gallons....well before the calculated regeneration point. It's been a while since we cleaned the...

If you mean the thimble-sized plastic inserter...yes....Thanks.

My old photocell system ran a lighting contactor. I simply connected the astronomic timer to run the lighting contactor (in place of the photocell).

I just off of the phone with Cat Pumps Tech support. It turns out that there are 2 DIFFERENT piston types....Machined Pistons, or Bac-Cup Pistons. I was trying to use Bac-Cup "Cups" on Machined Pistons. To use Bac-cup cups on a machine, the machined pistons need to be replaced with Bac-cup...

The 623 has valves in the head. Doesn't the head washout problem exist in plunger style pumps (which the 623 isn't)?
