In my view, tokens only are a sure fire way to drive repeat business to a competitor. Imagine that bar and grill you frequent providing tokens as change for your food and beverage tab. “What’s the problem? You’re a regular customer. You can use them next time you’re in for a beer.” How...

Especially when a quarter purchases 15 or 20 seconds.

I was assuming an older (Mike Doyle's IVS) vacuum. The several hundred 3 motor units that I sold were equipped with 3-pole relays (brand name escapes me) rather than a mercury relay. I can't speak to the Ginsan/IVS versions.

The Dixmor energizes the 24vac coil of the relay. 120vac (Line) is supplied to the Common terminals of the relay. When the relay coil is energized, the relay’s normally open contacts close, supplying 120vac to the motors (Load). Add fuses between the relay and the motors (Load) to save the...

Might check with Carolina Pride. Their systems are/were nearly identical to the old Southern Pride Turbo Spray wash racks.

Unlikely that all bays will be using fb or tri-foam simultaneously. Set each bay individually, then test 2 or 3 at a time to check quality of delivery. Start with 50 psi pump pressure and 25 psi air assist. Adjust the air assist up or down 2 psi at a time until you're satisfied...remembering...

There you go thinking again. :) If the Weepmizer doesn't like dirty power...no heat in the trough...no floor heat circulators...no Takagi. If the power goes out, N/O solenoids open...100% weep But, all your Output 2 devices are still dead. So? IF you want Output 2 devices to work with...

My experience echos I.B.’s pretty closely. I no longer fret about SBAs mixed in with the golden coins. After 13 years of $1 coins only, I guess the customers get it. Interestingly, quarters brought to the car wash still account for over 22% of my cash sales. I’ve put almost 90K $1 coins into...

YEA!!! My place survived the night! -17F according to my Weepmizer! The floors and aprons are even ice free even though the design temp for the system is +10F. I've had 2 customers today...washing at +4F. Yikes! Hope their doors and locks don't freeze solid.

I thought 2Biz was reading copper pipe temperatures. The infrared thermometers give inaccurate readings when directed at "reflective" surfaces like copper pipe and brass fittings. Something I learned in "plumbing for dummies school". ;) I have one installed on my boiler/rinse tank. I sealed...

Or, this one...although, it works best in an immersion well. http://www.pexsupply.com/Johnson-Controls-A419ABC-1C-Single-Stage-Digital-Temperature-Control-120-240v-SPDT For more accurate readings, wrap the surface with non-reflective black tape...like the stuff used on hockey sticks or...

So, 2Biz... Since you're designing, how many Takagis and Tacos will I need for my 7,680 sq ft of heated concrete? :D

2Biz, They rarely require "maintenance"...just replacement, since they're a sealed unit. Most of mine are Cat and are many years old. As Mep stated, a brass plug works just as well as a length of steel braid hose...dampener hoses are flexible fabric braid hoses. I'm not a fan of all that...

Since you have a pressure reducing valve (water make-up), cap the expansion tank tightly and bump the PRV to 18-20 psi. The increased pressure might squeeze the trapped air enough to allow it to release into the x-tank. Run the system for a few days with the higher pressure setting. We can...

Thanks w4m... I get it. I recently “downsized” to this 1950s brick ranch with zero wall insulation and only 6” of attic insulation. The original single pane windows are fitted with reasonable storms. I've run several heat loss calculations and came up with 60,000 Btu, maximum. The...

I'm preparing for the end-of-life of my 35 year old home heating boiler. ModCon boilers seem to be the "hot ticket" these days but I'm curious about their reliability. My understanding is the annual maintenance and service parts can really eat up the fuel cost savings. This could be a real...

For stainless steel tubing and compression fittings, try: MRC Global 47 South Maple Street Bellingham, MA 02019 508-966-3205 The best hp bay supply system...ever! Tubing is inexpensive and easy to work with if you use the right tools. Fitting are expensive but never have to be replaced...

Air trapped in a 200’ length of floor heat tubing will prevent liquid flow through that loop. The circulator cannot purge the air because it is likely sized for the flow/head of the entire system. By running one loop at a time, the circulator only has to overcome the head of a single loop and...

Turn off the gas supply to the boiler or disconnect the neutral wire to the gas valve. Open the expansion tank/fill port...(assuming closed system without make-up water supply) Close the supply valves for all the loops. Turn up the control stat so there’s a “call for heat”…this will turn the...

Somehow the bay plumbing is being evacuated... 1. Air blow/ out winterizing? 2. Lp chemical with air assist? 3. Leaking swivel? 1. Normal operation 2. Air solenoid leaking...adding air to the plumbing during idle times 3. Some swivels don't leak water under pressure. But, allow air in when...
