9: Maintaining Your SCA
As with any piece of equipment, proper maintenance is critical for safety and long life of
the SCA.
9.1: Cooling the Tank Liquid
Before draining the tank, make sure that all parts have been removed from the unit. If
possible, open the lid to decrease the cooling time as well. Never place your face near the
tank when opening the lid - vapors from the cleaning solution may cause eye and
respiratory irritation.
Leave the power on to the system to indicate the liquid temperature. Once it has reached
30ºC the tank can be drained safely.
9.2: Draining the Tank
Never drain the tank unless the fluid is at or below 30ºC.
Prior to draining, turn off power to the tank and unplug from wall socket.
Always wear protective gloves and eyewear when draining the tank.
You should drain the liquid from the tank if the unit will not be used in the near future or
if the liquid needs to be changed out because the cleaning solution is saturated with support
material.
Make sure that the strainer is in place at the bottom of the tank.
To drain the tank, attach a hose to the drain tube on the front of the unit. Place the other
end of the hose in a sink, or a plastic or stainless steel container that will be used to transport
the liquid to a drain after dilution. Secure the end of the hose in the sink or container so
that it cannot come loose during draining.
Turn the drain valve to the “Open” position.
Once the tank is drained, make sure the drain valve is in the “Closed” Position.
Note: use 1” inner diameter PVC tubing or equivalent on the drain tube. Ensure the tubing
or hose can withstand the temperature and caustic properties of the cleaning solution.
