1-8. DIFFERENCES BETWEEN MODELS.
This manual covers the United Manufacturing and Engineering Corporation Model Style 1,Model 2519, Model
2938, Bowser Model 36W50 Orr and Sembower Model BL-100 and Altech Model 4000 Tank and Pump Units. The
differences in these five models are in the filter/separator, hose reels, pump and manifold. Where differences exist,
each model is covered separately in the appropriate maintenance section of the manual. The canister screen and
elements in the filter/separator are different on some models now in use; however, all future models will use the type
shown in this manual. Differences in manufacturing of repair parts for manhole assemblies and discharge valve
assemblies will make it necessary to replace with parts manufactured for that particular tank. Models 2519 and Style
1, Orr and Sembower and others, have no discharge line running from the filter/separator to the manifold and therefore,
the manifold is used for suction only. ModeIs 2938 and 36W50 have a discharge line connecting the filter to the
manifold which permits discharging from the manifold outlet as well as from the two reels. Model 2519 and Style 1
discharge from the two reels only.
