without external support
Tank Unpacking and Inspection
1. The top and upper portions of the Roth EcoDWT plus 3 are covered with shrink wrap plastic
designed to keep the top of the tank weathertight. The shrink wrap must be left in place
until the tank has been moved inside or is ready to have the cover placed on it if an outside
installation. It is transparent, so the tank top and connections can be examined for damage.
The base for each tank is shipped on top of the tank to protect the fittings during shipping.
2. The tanks are inspected for damage before shipment from the manufacturing facility and
must be inspected for shipping damage upon delivery. If damage is found, the wholesaler or
shipper, not Roth Industries, must be notified.
3. In the course of shipping and handling after the tanks leave the Roth warehouse, some
minor denting and scraping of the tanks may occur. Minor scratches and scrapes on the
surface of the galvanized steel outer tank can be easily repaired by cleaning the surface
with any common degreaser and then coating the affected area with any zinc bearing paint
designed for such repairs. Most hardware and building supply stores will carry one or more
brands of galvanizing repair products.
4. Dents of a ¼ inch depth or less above the curved portions of the sides or in the end panels
are generally considered minor and will not affect the integrity of the tank. If the deepest part
of the dent forms a sharp projection against the inner tank, or if the dent is on or below the
curved sides, this can abrade the surface of the inner tank over time and weaken it.
A tank
damaged in this way should not be used.
5. If the rolled seam has been struck and is distorted to the left or right ¼ inch or less, the
sealing compound will still be intact. Any seam distorted more than ¼ inch or directly dented
in will have the sealing compound compromised and should not be used. Any tank installed
with unacceptable dents will not be covered by the warranty.
Contact the Roth Industries Technical Department if you have any questions concerning
dents or scraping on the units. Typically, you will be asked to send pictures of the tank.
