GLOSSARY OF SPA TERMINOLOGY Your new spa features a variety of jets. All jets, regardless of style, return the water to the spa. Air is mixed with the water by using the air controls (if equipped) creating a vigorous massage. Water flow is adjusted by simply turning the outer face of most jets.
Page 17 All of the skirt panels are removable should service be required. Side Side “B” “D” Master Spas recommends at least 3 feet of access be provided around the spa. 11.

Page 21: Water Chemistry Terms You Should Know
WATER CHEMISTRY TERMS YOU SHOULD KNOW EN 17125 Before jumping into Water Maintenance, here are some terms to help you. 1. PARTS PER MILLION (PPM): This is a form of measurement used in most pool or spa chemical readings. Best described as any one million like items of equal size and make up, next to one unlike item, but of equal size.
Page 22 WARNING: Do not use other salts systems. Only the Master Clear Salt System is approved for use on the Master Spas hot tubs. Other systems will result in unwarranted wear or damage to the spa components. C. Bromine 1.
Page 23: Why Are Chemicals Important In A Spa
WHY ARE CHEMICALS IMPORTANT IN A SPA EVAPORATION: As water evaporates, only pure water evaporates, leaving the salts, minerals, metals, and any unused chemicals behind. Adding water adds more salts, minerals, and metals. In time, the water can become saturated with these dissolved solids and can cause stains or scale to form on the walls of the spa or a scale build up inside the equipment.
Page 24: Water Maintenance
WATER MAINTENANCE – RECOMMENDED RANGES WATER CHEMISTRY GUIDE Before treating your water, refer to the Model Specifications section of this manual for the correct gallons of your spa, to ensure you are adding the correct amount of chemicals. The concentration of active ingredients in spa chemicals varies by manufacturer, so always consult chemical manufacturer's instructions.
Page 25: Start
1. Your spa should be filled with fresh tap water using a Pre-filter, which can be obtained from your local Master Spas dealer. This Pre-filter will help remove many of the minerals existing in the water, which will make adjusting the water balance easier after a new fill.

Page 34 CARE OF YOUR SPA COVER Always cover your spa when not in use with an approved insulating spa cover by Master Spas. Keep the spa cover on to minimize heat loss during heating of the spa between uses (but not while it is being used).
Page 35: Care Of Stainless Steel
CARE OF STAINLESS STEEL Master Spas uses stainless steel in a number of our spas. Its lasting beauty and resistance to corrosion make it an excellent material for handrails and jets faces. With the proper care it will keep its luster for many years.

Page 38: Winterizing & Storing Your Spa
However, if you decide you don’t want to use your spa in the winter, you must drain it and follow the winterizing steps listed below.* DISCLAIMER: Master Spas does not recommend winterizing your spa. If you choose to do so, any damage that may result is not covered under the spa warranty.

Page 45: Skirt Cabinet Panel Removal
SKIRT CABINET PANEL REMOVAL The skirt cabinet panels on your hot tub will need to be removed during initial installation and startup as well as for regular inspection and maintenance of the internal components.

Page 46 SKIRT CABINET PANEL REMOVAL 3. To remove a main side panel, you will also need to remove the associated corner panels that overlap the panel at its ends. Each corner also has a transport clip that needs removed. Remove the screw, slide the clip to the left and pull the clip down and out to remove.
Page 47 6. Before removing the panel away from the spa, reach behind and disconnect the LED cabinet lighting. The front cabinet panel with the light up Master Spas logo has two types of connections. The right side with the logo has two spade connectors, connecting to supply power.

Page 49 Due to the nature of water flow and hydro-therapy pumps, please be advised that air locking of pumps may occur. Master Spas has taken measures to reduce the possibility of this, but it still may occur, especially after refilling a spa. This is not a service covered under warranty and service charges may apply.
