Operating Level
At design flow, the operating level should not be less than 2 inches or greater than 6
inches deep.
Inspection and Maintenance
• Quarterly, or more often as required, remove any dirt or debris which may clog the
nozzles. Seasonally, clean and flush the hot water basin with fresh water.
• Access to the nozzles requires removal of the hot water basin covers.
–
To remove the covers turn the knobs to remove the threaded studs (
Figure 6
). Then,
lift the hot water basin covers vertically by using the attached handles. Once the hot
water basin covers are removed, the nozzles may be cleaned.
• If access to the nozzles under the pre-distribution chamber is required, remove
the hardware that fastens the tabbed baffles, then remove the panels. Retain the
hardware to re-install the tabbed baffles.
Optional EASY CONNECT
®
Piping Arrangement
The Series 3000 Cooling Tower has an optional EASY CONNECT
®
Piping Arrangement,
which is equipped with a capped cleanout connection. The water to be cooled enters the
tower through a single connection and passes through the EASY CONNECT
®
Chamber,
supplying water to both hot water basins. See
Figure 7, page 30
.
Water Level Control
There are two types of water level controls used on Series 3000 Cooling Towers:
• Mechanical make-up valve assembly
• Optional electric water level control package
The Series 3000 water make-up valve assembly is located at the connection end of the
unit.
ATTENTION
: Do not use steam or
high pressure water to clean PVC
eliminators or materials other than
steel.
