Reservoir Fluid

Periodically inspect the reservoir fluid. If cleaning is necessary, flush the
reservoir with a cleaning fluid compatible with your application.
The reservoir fluid should be replaced periodically. Frequency depends on the
operating environment and time of usage.
Before changing the reservoir fluid ensure it is at a safe handling
temperature.

Reservoir Cleaning

Routine cleaning can be achieved by simply sponging down the seamless
stainless steel tank with tap water. (Dish washing detergent may be used but
the tank must be thoroughly rinsed.)

Algae

To restrict the growth of algae in the bath, we recommend that all circulation
lines be opaque. This will eliminate the entrance of light required for the growth
of most common algae.
We recommend the use of Chloramine-T, 1 gram per 3½ liters.
