•
Drain the model and reservoirs after each use; do NOT leave water in the Emriver models.
•
To keep your model sanitary, change out the water every day and drain the table by lowering
the standpipe all the way.
•
If you cannot change the water every day,
add about 6 ml of household bleach to the reservoir
every day, and run the pump to distribute it through the system. This will prevent algae and
bacteria from colonizing the model. You may also use widely available home water filters to
remove contaminants.
Adding too much bleach or chlorine can damage the aluminum parts.
•
Never use lithic materials (i.e., sand) in the Emriver tables.
•
Do not use metallic objects in the model.
•
Power down the pump and controller after each use by disconnecting the pump from the
controller, and disconnecting the controller from the power supply.
•
Do not use solvents, which may dissolve or weaken the plastic tubing. If the tubing is left in the
sun while wet, it may support algae growth and become cloudy. Routing a mild bleach
solution through the tubing after use will minimize this problem. Removing all standing water
in the lines will help as well. If tubing becomes cloudy you may purchase a replacement from
us, or buy from your local hardware store, but that which is supplied with your model is a high
quality type and is longer lasting and more flexible.
•
All bolts on the supports should be periodically checked for tightness. Loose or missing bolts will
affect the strength of the supports. The bolts should be as tight as possible while still allowing
the supports to fold.
•
Clean the filter on the pump periodically by unscrewing the filter from the pump and thoroughly
rinsing it inside and out.
