Connecting Plumbing to Remote Equipment
Connecting the plumbing from the spa to the equip- ment 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, mini- mize 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 the air blower.
Air Venturi: 1/2” line that is plumbed 18” above the spa’s water level.
Topside Control Panel and Temp Sensor: 1” line that connects to the bottom of the control box located on the equipment pack.

Remote Equipment Topside Control Panel
The next few steps to complete the installation should be performed along with installation of the tempera- ture sensor and 12V spa light wiring (if applicable). All of these components are generally installed using the same conduit.
1.Locate the topside control panel extension loom in the control box mounted with the equipment pack. This extension loom and attached black ter- minal connector (see figure at right) will be used to connect the topside control panel to the control box.
2.Connect one end of the black terminal connector to the topside control panel cable.
3.Connect the other end of the terminal connector to the extension loom.
NOTE: This connection must be kept dry. We recom- mend that a waterproof junction box be used in instal- lations where moisture could penetrate this terminal connector.
4.Lay out the extension loom to verify that you have enough length to reach the control box. Remem- ber that conduit runs are not generally run in a straight line. Every bend, and up and down run consumes line length. Take this into consideration when verifying electrical and plumbing runs.
5.Connect the extension loom to the control panel location on the circuit board located inside the control box. You will also need to connect both the temperature and high limit sensors to the cir- cuit board prior to testing. (See the temperature and high limit installation instruction on the next page for proper identification and see the wiring diagram on the inside cover of the control box for proper placement.)
6.Turn on the power supply to the spa equipment and briefly test all functions on the topside control panel to verify that both connections and exten- sion loom are in working order before proceeding with the installation.
NOTE: Circuit board programming will not allow spa operation without both the temperature and high limit sensors being properly connected to the circuit board.
