GENERAL MAINTENANCE GUIDE
To ensure the maximum life of the JMC16, please follow the procedures below:
1. Visually monitor through the JMC16 clear sediment chamber. Clean sediment chamber
when accumulated sediment is half full.
2. Maintain a correct chemical balance of your pool / spa water. The chemical balance of
water is a relationship between its pH, total alkalinity, calcium hardness and water
temperature. The water must be maintained at all times to the following:
PH LEVEL
TOTAL ALKALINITY
CALCIUM HARDNESS
Also, within these tolerances be balanced to the Langelier Saturation Index within a
range of -0.2 to +0.2.
Note: Testing kits are available to test the water yourself or alternately bring a sample of
the water to nearest Leslie's Store.
3. Mains water and rural water supplies need to be monitored. Saturation (life) in mains
water or bore (rural) will vary depending on water quality.
4. To prevent damage to the pump and filter and for proper operation of the system,
clean pump strainer and skimmer baskets regularly.
5. Replace the pressure gauge if faulty readings are observed.
