    Credit Card skimmer/vandalism - Unitec POS

    I've heard and read about CC skimmers being installed in Gas stations in and around Austin. Never occurred to me that these idiots would try carwashes. Well they tried mine this past Sunday, in broad daylight, while customers were washing/waiting. All this just as my attendant clocked in for the...

    LW4000 High Pressure (arch) issue

    UPDATE - it was indeed the brass body of the Lexair that was worn out. Found a new one on Ebay ($100), swapped it out (took about 2hrs since some of the plumbing was rock solid). Back in business. I wanted to replace the Lexair with Dema but couldn't figure out how to wire it and get rid of the...

    LW4000 High Pressure (arch) issue

    Update - as suggested, I checked the HP check valve on the manifold, and the hose for kinks - all checked out fine. Next, I connected the air line directly to the RHS lexair (undercarriage), thereby bypassing the mac valve and forcing the u/c to stay closed. Same problem. Sounds like what...

    LW4000 High Pressure (arch) issue

    Yep, the LW uses this: https://www.kleen-ritecorp.com/p-4660-14-24v-mac-valve-solenoid-valve-for-laser-wash-912b-pm-221caab.aspx As noted, I already replaced this (first tried cleaning it, then just replaced it).

    LW4000 High Pressure (arch) issue

    When the arch is enabled, i'd say the water is 50/50 between the arch and undercarriage. When the undercarriage is enabled, nothing comes out of the arch. This is why I'm assuming the unloader is fine. No visible rust (I've cleaned rusty unloaders in my other locations). All my LW4000 bays have...

    LW4000 High Pressure (arch) issue

    Thank you for the suggestions. Didn't think of unloader because as @UndertakerII noted, if the unloader was bad I assumed it would affect both the u/c and arch. There are 2 HP unloaders and iirc, one is for the clearcoat (800 psi). @Ontario Car Wash - yes, when the arch is spraying (at 400psi)...

    LW4000 High Pressure (arch) issue

    High Pressure in arch is really low (440 psi). Undercarriage is perfect (1100 psi). Have already tried the following: rebuilt both lexair valves swapped lexairs, again undercarriage is fine, arch is low cleaned, then replaced Mac Valve cleaned all nozzles replaced weep check valve...

    LW4000 Left limit on width measure - X22 with VT ?

    Getting "Left limit on width measure" error. This is during startup, when arm goes past the front to measure. Festoon is new (1 month old), replaced X30 (worn out) and the rusted pickets in the bridge. The wiring from J2-J3-J4 for the X22 is all disconnected, so it seems the big X22 sensor is...

    Anyone know where I can find a refurbished Hamilton ACW handheld kit or anything cheaper than $437 for this: http://hamiltonmfg.com/products/100-0136-audit-pro-handheld-kit-complete Mine is acting up. 1 row (123) and 1 column (147) on the keypad are not responding. Tried opening it up and...

    Source for replacement unitec modem?

    I know this is an old thread, but wondering if any Unitec owners in the past 2 years have come up with alternate sources for these WashSelect II modems? Unitec's price is still the same: $1500 new $600 refurb (provided you send in the old one). I called the modem manufacturer (DataCap Systems)...

    Coleman vac containers / totes

    Curious if anyone has found a replacement for the Coleman vacuum containers or totes. I have several blue Recycle totes, and curiously enough 1 (and only one) seems to be a perfect replacement. The coleman totes are 17"x20.5"x12" and the recycle tote (that fit) is 17"x22"x12". I ordered item#...

    Need: Used PDQ (LW4000 stainless) x 2

    I'm looking for 2 complete LW4000 (stainless) systems (all bay items, pump stand, dryer etc.). Don't need ACW. May consider M5 but prefer the old-style. Prefer low-car count and minimal rebuild. Will take care of delivery.

    Leak in Spray Arch Manifold / Horn

    On one of my LW4000 I have a leak in the spray arch manifold, where the side and top spray arms meet. I notice on the PDQ Parts list that there's an O-Ring kit and ball bearings that goes in the manifold. Additionally, the side arm has a lot of swing compared to my other bay, and on the HP...

    Splicing rear eyes - how ?

    Warning : newbie question :-) I started getting "rear eye" failures. After reading some posts, I've tried increasing the Y41 amp sensitivity, to no avail. So I've decided to replace the rear eyes (both Tx and Rx). New eyes have arrived. I spliced the cable in the T-bar, instead of replacing...

    Multi-coin acceptor - how ?

    Awesome ... that's exactly what I needed to know. There is already something like a 2-way chute/coin-diverter under the current Slugbuster, so all I would need is the skinny hopper I guess. Thanks.

    Multi-coin acceptor - how ?

    One of my WS II is set-up strangely : it accepts quarters but dispenses $1 coins for change. It was like this when I bought it. Previous owner put a towel with paper clips in the hopper to prevent the quarters from falling into the hopper which contains $1 coins. The coin acceptor is a...
