NOTE: Coast Spas recommends you do not fill your spa with hot water. Excessively hot water (over 107 ºF) may cause damage to components in the spa pack as well as all plastic and acrylic components.
NOTE: Do not fill your spa with water from a water softener. If your water is extremely hard your Coast Spas dealer can help you to remedy this problem.
All Cascade Series Spas have a specific fill line located in the window (found to the left or right of the equipment area) on the side corner of the spa. This is a clear sight tube that is marked with colored lines. The ball inside the tube indicates the water level. Yellow = 1 person. Green = 2-3 people. Red = 4-6 people.
After a period of 3-4 months, detergent residues from bathing suits and soap film will build up in your spa water. Once this happens, your spa water will appear cloudy and should probably be replaced.
IMPORTANT (Cascade Series Only): There will be an additional drain valve. This is connected directly to the tank reservoir and you will see the water level go down on the sight tube in the equipment area.
In many areas of the world the temperature may drop below 32°F (0°C). We recommend the spa is always filled with water and running at normal spa temperatures. By doing this you will minimize the risk of freezing within your spa. If it is necessary to leave your spa unattended for long periods of time during cold weather conditions, you should drain your spa to avoid accidental freezing caused by power outages. Your Coast Spas dealer can perform the following winterizing procedures, if you are not completely comfortable with them.
EMERGENCY SITUATIONS: To eliminate freezing in the event of equipment failure, use a 100-watt light bulb or small heater via extension cord and place it in the equipment area, keeping it away from plumbing lines. This will help for a short period of time until proper service can be rendered.
