This can be done by using one of the following techniques. Air Test The air test requires a wet/dry vacuum. Locate the plumbing line you wish to identify and secure the vacuum hose to cut open end. Turn on the vacuum, enter the spa and listen for vacuum suction sound from inside the spa side filter canister. If you hear the suction sound in the canister, the line is properly marked and can be connected to the suction side of the pump on the equipment pack. Water Test The water test requires a garden hose and water source. Locate the plumbing line you wish to identify and secure the outlet side of the garden hose to cut open end. Turn on the water supply to the garden hose, enter the spa and look for water inside the spa side filter canister. If you see water in the canister the line is properly marked and can be connected to the suction side of the pump on the equipment pack. If any plumbing line is not properly marked or not marked at all, follow either the air or water test procedure until all lines are identified prior to gluing. NOTE: Once complete, water test the plumbing run for at least three days prior to covering any plumbing trenches and back-filling spa cavity completely. NOTE: Some local inspectors require pressure testing the plumbing lines. Although the spa is pressure tested at the factory, local inspectors may insist on pressure testing the plumbing run between the spa and equipment pack. Gate/Slice Valves The use of gate valves is recommended on all plumbing lines (both suction and return lines). These valves are used to contain the spa’s water in either the equipment or the spa. This will assist in the pump priming process and future servicing without needing to drain the spa. NOTE: When draining the spa to perform maintenance, always close the gate valves prior to draining. This will maintain the pumps prime. Connecting Plumbing to Remote Equipment Connecting the plumbing from the spa to the equipment pack must be performed in accordance to local and city codes. NOTE: Most codes require plumbing to be rigid PVC schedule 40 or heavier in both above and below ground installations. In most cases, the use of flexible PVC plumbing is acceptable when properly buried in trenches. Most water plumbing lines are 2” or larger and must be schedule 40 or heavier PVC. When plumbing, minimize the use of 90. elbows as much as possible. The use of 45 . elbows will increase the amount of jet pressure you will have over the use of 90. elbows. The plumbing on the spa shell is labeled by the factory in the following manner: Pump 1 Suction: 2” line that connects the spa filter and bottom drain assembly to the front of pump 1. Pump 1 Return: 2” line that connects the top of pump 1, through the equipment filter and heater back to selected jets in the spa. Pump 2 Suction: 2” line that connects the spa filter and bottom drain assembly to the front of pump 2. Pump 2 Return: 2” line that connects the top of pump 2 back to selected jets in the spa. Ozone Line: 1” line that connects to a 1” flexible line extending off the bottom of the equipment pack filter canister through an ozone injector (If ozone equipped) and connected to ozone port on the spa. Air Blower: 1 1/2” line that is plumbed out of the air blower (located on the equipment pack) and extended up 18” above the spas water level to prevent water flooding...
