10.1 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

8 “B” tubings
2 “C” tubings
2 “D” tubings

The drawing above shows one complete reagent tubing set. Two complete 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 inc. distributor or representative. It is recommended to keep one kit on
hand at all times.
Generally, all “B” tubes should be replaced on a three month basis. The “C” and “D”
tubes and the cuvette should be replaced annually. If the CLX is operated in an ambient
temperature above 27
° C (81° F), the “B” tubes should be changed every two months.
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 (if used) 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.
