SECTION 5: PRE-INSTALLATION

5.7 Control Panel Considerations

Most Rotofilters are purchased with a control panel.
This manual describes operation and maintenance
procedures for units that utilize a control panel. If
a control panel was not ordered with the Rotofilter,
one may be ordered at any time.
The control panel allows toggling between
Automatic Mode, Manual Mode, and Off for the
drum rotation and backwash systems. The panel
also displays Power-On and Unit-Run conditions.
The control system is made from high-quality,
industrial-grade, CSA- and UL-approved
components. The control panel box is a waterproof,
corrosion-proof CSA- and UL-approved electrical
enclosure that can be secured with padlocks. The
control panel assembly is manufactured in a UL-
certified facility, and should not be modified. Any
modification voids the UL rating.
The control panel should always be installed within
line of sight of the Rotofilter. If this is not possible,
disconnects for the drum motor and backwash
pump system must be installed next to the
Rotofilter as a safety precaution. The control panel
door should be able to open fully.
All electrical work should
be performed by a qualified
electrician. This manual does
not provide electrical installation procedures
or wiring diagrams.
The control panel installation location should
be outlined and diagrammed prior to Rotofilter
installation. The location should allow ample room
for electrical fixtures and should not interfere with
the service clearance required by the Rotofilter.

5.8 Electrical Power Requirements

The electrical power requirements for the Rotofilter
motor and backwash pump are listed in the
Technical Specification sheet sent prior to
Rotofilter arrival.
All electrical work should
be performed by a qualified
electrician. This manual does
not provide electrical installation procedures
or wiring diagrams.

5.9 Flushing Plumbing

The plumbing that will be connected to the
Rotofilter should be thoroughly flushed prior
to Rotofilter installation. Flushing the plumbing
removes debris that could damage the screens and
internal components of the Rotofilter.
All removed material should be collected and
disposed of properly.
To flush a system, the discharge valve should be
opened first, then the charge valve. Flush for at
least 2 minutes. If there are multiple circuits within
a system, flush one full circuit at a time, each for at
least 2 minutes.
To prevent potentially dangerous pressure buildup,
open the next circuit discharge valve before closing
the preceding discharge valve. When all plumbing
has been flushed, shut off the charge valve first and
then shut off discharge valves.
