Using the ASI 0387 is easy. First, make sure it's properly installed under your vanity for models 0338 or 0389. The top-fill feature allows you to add water conveniently. Just open the fill port and pour water into the 6L tank. When using it, avoid overfilling the tank. For maintenance, clean the fill port regularly to prevent blockages. If there are any issues, check the connections under the vanity. Keep it dry and away from sharp objects to ensure its long - term use.
