Securing Floor Standing TTS-TWST Models • All mechanical components shall be anchored and installed in accordance with national and local codes including anchorage to building structures. • For minimum concrete thickness, refer to local codes or consult with a licensed structural engineer regarding the use of appropriate expansion anchors capable of supporting the TTS weight. -
Page 28: Freeze Prevention / Insulation
Freeze Prevention / Insulation • In normal operation, freezing is prevented within the device automatically unless the outside temperature without wind is below -30°F (-35°C) for indoor installation or -4°F (-20°C) for outdoor installations. • For models installed in an area where the outside temperature can approach freezing conditions of 30°F (-35°C) or outdoor -4°F (-20°C) or below, then additional protection measures must be used. -
Page 29: Condensate Drain To Floor Or With Pump
Condensate Drain to Floor or with Pump • Each TTS unit comes with a condensate drain pre-piped which must be properly drained to ensure proper operation of this appliance. • The pH level of the condensate is approximately 2-3. An external neutralizer must be installed on the drain piping prior to disposal when required by local code or when the condensate could cause damage. - Page 30 • If the water heater has been out of use for a long period of time, make sure that you fill the condensate trap with water. This is to prevent dangerous exhaust gases from entering the building. Failure to fill the condensate trap could result in severe personal injury or death. * Do not use the condensate water, discharged from the drain pipe, for drinking purposes.
