    Problems with a aircon/heatpump

    Hi I am taking a long shot here I am looking for information circuit diagram or any documentation on a L.G. LSU H226 DMO Heat pump I have asked L.G. but the reply I receive LG's service manuals are not available to the public. Access to these service manuals are only available to LG'S technicians. I have 2 that are faulty and have to repair them.

    Thanks :

    Try this link (i'm hoping it's not a server cached result) copy/paste it from the codebox into your browser address bar.

    Code:
    http://www.lg-dfs.com/technical-support-service-manuals.aspx?page=1&pagesize=25&resourcesType=&category=&product=&orderbyLangAsc=True&orderbyLangDesc=False&orderbyCategoryAsc=True&orderbyCategoryDesc=False&orderbyProductNameAsc=True&orderbyProductNameDesc=False
    You might find something relevant even if it's a variation on the exact model you're looking for.

    Thank you AndyD, you are a mine of information couldn't get the exact model but close enough. What puzzled me was the double capacitor need to know what wire went where.

    Hi Guys I have been asked to install a SIRAC heat pump for a household family, which i am not familiar with. Rather than make a mess I'd like to know if anyone has done one of these before?
    Basically my question is I have 3 connections to make.
    1. Main Incomer from DB
    2. Circulating Pump Connection
    3. Backup Electricity Heating Element Signal Connection

    The first 2 are easy but could anyone tell me what the 3rd is? Can I connect the geyser element to the number 3 connection?
    Remembering that the old thermostat has been replaced with the new heat pump one.
    Thanks

    I think it's something tol do with freeze-up protection. It says in one of the manuals it's optional. I didn't have time to find a wiring diagram but I'm sure if you scratch around on the sites below you'll find one.

    You didn't give a model number or state if it's a pool heater, secondary water heater etc. so here's some blind suggestions;
