#School mate 2 controls install
Install the new topside controller using the supplied adapter plate if necessary.Note: Always install a new blower check valve. If the tub has an air blower, connect it to the plumbing.If plumbing cannot be manipulated to achieve this configuration, a flow switch kit will be required. Note: EasyPak systems are designed to be connected to the discharge end of the pump. If replacing, install the new pump(s).You’ll want to determine whether they can be reused or should be replaced. Take an assessment of the pumps and other components.Disconnect the plumbing from the heater.Oftentimes, using fishing line or dental floss to get in between the shell of the tub and the topside helps. Note: Most topsides are attached using silicone sealant or double stick tape. Disconnect and remove the topside controller.Disconnect the electric and component cords from control system (pump, blower, etc.).Disconnect incoming power cord from equipment system.On 120V spas, unplug spa from the receptacle. On 240V spas, shut-off the breaker at the main panel servicing the house, and the GFCI Sub-Panel servicing the spa. We’ll use your voltage selections to pre-configure the system for an easy installation.Īll control system installations are a little different, but here’s a general overview of the steps involved.Ĭaution: Make certain the power is disconnected before proceeding. Once you know how many pumps/blowers your tub has and what kind of heater, you can select a control system. Once you’ve located each component, note the voltage, which will be listed on its data label. The next step is to determine the number of pumps and other circuits your tub needs.ĭetermine what components your tub has by following each cord attached to the control system to its respective component. Great! You‘ve decided on digital or air controls and selected the correct heater type. The plumbing and existing pumps must match up to the new pack to avoid damage to your new system.
The new control system you choose will include a new heater. These pumps have a plumbing size of ¾” to 1”. Low Flow heaters have ¾” to 1” plumbing with a dedicated 24-hour circulation pump that flows 10-20 gallons per minute.The pump must be at least 1.5”, and be either a dedicated, single-speed circulation or a dual-speed jet pump. High Flow heaters have 1.5” to 2” plumbing and are fed by a pump with a flowrate of 25 gallons per minute minimum.There are two basic heater types: High Flow and Low Flow. The style of heater that your spa already has plays a critical role when choosing a replacement control system.
When replacing the entire brain of a hot tub, ensure the heater, topside and physical dimensions of the system fit. How Do I Choose the Right Control System? These tubes are similar to those used in fish tanks or medical drip systems. How Do I Know if I Have a Digital or Air System?Īn easy way to tell the difference between digital and air systems is to look at the keypad connection.ĭigital systems will have one electrical cord extending from the keypad to the main control pack.Īn air system will have 1/8” vinyl tubes connecting each button to the control system, in addition to any electrical cords.
#School mate 2 controls update
If your tub has an old air system, you can definitely update your spa with digital controls. While they’re still available, most air systems have been replaced by digital controls. These pneumatic switch type controls were used on the early tubs of the 1970’s through 1990’s. Non-digital air systems have buttons that send a puff of air to switches, turning each function on or off. When any issues arise, Error Codes will display. The control keypad on top of the spa allows communication with the control pack. The circuit board inside can run sophisticated filtration cycles and onboard diagnostics. There are two types of control systems used in hot tubs: electronic, digital type systems and older-style mechanical air controls.ĭigital controls are solid state computer-controlled systems. This nerve center controls the functions and equipment in the spa, like the jet pumps, filtration time, and heater.
The control system, or spa pack, is the brain of the hot tub. Shut off electrical power to the hot tub or pool at the service panel prior to any inspections or work. Electrical wiring and repairs can be dangerous, especially around water, and must be performed by a qualified electrician or spa technician.
