1-11. DIFFERENCES BETWEEN MODELS-continued.
a.
Only models WPES- 10 and H-9518-1 are mounted on a flatbed cargo trailer. A self contained 30KW
generator set, installed on the trailer, supplies electrical power for operation of the unit. Models
WPES-20, H-9518-2, WPES-30 and H-9518-3 are skid mounted (no trailer).
b.
Models WPES-20, H-9518-2, WPES-30, H-9518-3 get electrical power from an external source that is
not supplied with the unit.
c.
Differences in the electrical systems are:
(1) Models WPES-10, H-9518-1, WPES-30 and H-9518-3 have only one external power connector
on the junction box. Internal wiring between these four models is identical.
(2) Models WPES-20 and H-9518-2 have two external power connectors on the junction box. One
connector supplies power to the high pressure pump (R.O. pump) motor, the other supplies power
to remaining system components. Both power cables must be connected to operate the unit.
Internal wiring is different between these units and models WPES-10, H-9518-1, WPES-30 and
H-9518-3.
d.
Differences in the piping systems are:
(1) Piping on models WPES-20, H-9518-2, WPES-30 and H-9518-3 are identical. On these models,
the R.O. elements must be removed from both the front and back of the R.O. vessels.
(2) The 30KW generator set installed on the flatbed cargo trailer of models WPES-10 and H-9518-1
prevents removal of the R.O. elements from the back of the R.O. vessels. Piping is different on
these models to allow removal of all R.O. elements from the front of the R.O. vessels.
