4.2.2 Cleaning Clogged Solution Tube
Where solution joins water being treated and that water contains
considerable hardness, there may be a deposit formed inside the solution tube
at the point of application. In time, this can completely plug this tube and the
deposit must be removed. The best method is by dissolving the deposit as
described in paragraph 4.2.1. Where this condition is known to exist, clean the
solution tube as a part of routine maintenance.
4.3 Periodic Preventive Maintenance
To minimize unscheduled shut down and ensure maximum service life, perform
periodic maintenance at specifi ed intervals while the equipment is in
satisfactory condition. Table 4.1 lists the intervals, maintenance operation, and the
preventive maintenance kits required. Before starting the work, ensure that the
appropriate preventive maintenance kits are in stock. Refer to Section 6 -
Preventive Maintenance Kits and Spare Parts List for the appropriate
maintenance kit.
NOTE: Although all parts are designed for long service life, it is
recommended that routine maintenance be performed to safeguard against
unexpected downtime.
