REV 6.0
10.0 Routine Maintenance
10.1 Normal Maintenance Schedule
The recommended schedule is shown below. It is important to replace the reagents on a
monthly basis to get reliable accurate readings from the CLX.
The CLX is shipped with one CLX Tubing/Cuvette kit, HF part # 09950. The kit consists
of the following:
Qty Part
2 Cap Assemblies
8 Pump Tubes
1 Cuvette
Two complete cap assembly sets are used in the CLX; one for the buffer and one for the
indicator.
The supplied kit is intended to last for one year. Additional kits can be ordered from your
local HF scientific distributor or representative. It is recommended to keep one kit on hand
at all times.
Generally, all pump tubes should be replaced on an annual basis. The Cap assemblies and
the cuvette should be replaced as required.
Every Month
1. The reagent required for operating this instrument must be changed on a monthly
basis (with a 2.5 minute cycle time).
2. The external strainer should be checked and cleaned if necessary
3. The glass cuvette should be inspected. Check for excessive debris on the inside
surface of the glass. It is suggested to keep a spare cuvette to replace when required.
The old cuvette may be cleaned, if possible, for future replacement.
Flushing the System
It is recommended that the tubings replacements be timed with reagent replacement. Press
the SERVICE button to stop the water flow. Remove old reagents and discard. Place the
inlet tubings in a small container of clean water. Press SERVICE to return to operation
mode, press PRIME and then to flush the system with water. Remove the inlet tubings
from the water Press PRIME and then to remove most of the water.
After a PRIME the CLX will perform a water calibration (WCAL). It will take a few
minutes to complete this procedure.
