How To Replace A Hot Tub Pump-denka

Home-Improvement Do you know how to replace a hot tub pump ? First make sure the pump is actually the .ponent causing the problem. Many technicians troubleshoot by disconnecting things to isolate the problem .ponent. Sometimes a heater may be creating a short circuit or even an ozonator or blower,so before blaming the pump, it should be clear that the problem does indeed lie with the pump itself. Once it is determined that the pump requires service or replacement, important identifying information can usually be found on the pump label(s). Make sure that the replacement pump conforms to the specifications of the original pump including pump size, plumbing hookup size (usually 1 1/2 inch or 2 inch), frame size (48 frame or 56 frame), voltage (110V or 220V) and other Some factors to be aware of include what line frequency your particular country operates on. ( 50 hertz or 60 hertz) Replacement of any electrical hot tub .ponents should be left to qualified personnel to avoid electrical shock or injury. Before replacing a pump, assure that the power supply to the spa is turned off and also that the power breaker is off. In order to get ready for the pump exchange, the spa must either be .pletely drained to avoid flooding the equipment bay, or in the case the spa has slice or gate valves on either side of the pump, these need to be closed to assure water will not drain out of the full spa while replacing the pump. Sometimes the valves will not .pletely work in order to stop water from .ing out as they can have their own problems (ball valves are usually better than the slice valves). With many spas, the unions connecting the pump to the plumbing can be loosened by hand, or you may need large pliers, channel locks or other large wrench to loosen them. Make sure when removing the 2 ends of the plumbing to keep the o-rings found inside the unions. These little black o-rings keeps water from escaping at the union that joins the pump to the main spa plumbing. If the o-rings are worn then replace them. To remove a spa pump, unscrew the mounting screws that hold the pump to the spa base. The electrical connection to the spa pack should be disconnected. Some plugs fit on the side of the spa pack while other pumps are plugged in directly onto the circuit board (such as on newer style Balboa spa packs). The grounding bare copper wire also needs to be disconnected from the spa pack by unscrewing the terminal screw. Once the defective pump is unbolted from the floor, unplugged from the hot tub power pack including the grounding wire, and unhooked from the 2 water pipe unions, it can freely be lifted out of the spa electronics bay. Take care to keep the old power cable to your pump because you may want to use the original power cable again in the case it is not damaged or the cause of any electrical short as many replacement pumps do not .e with the cable. Since different spas have different pump electrical plugs or hookups, you would either need to specify what type of plug you have when ordering the replacement pump or use your existing power wire from the bad pump. To remove the original power cable, loosen the cable clamp screws and find the removable access cover that has the electrical terminal connections inside. Wire ends should be clean and not frayed. Be sure to note how the different colored wires are hooked up. Typically in a two speed spa pump in North America you will have 4 wires: green, white, red and black. Green (or green-yellow striped in Europe) is the ground wire, white is the .mon wire and usually red is the low speed supply and black is the high speed supply. When ordering a replacement pump, it is easiest to verify the pump specifications by looking at the label on the old pump. Not all 220 volt spas use 220 volt pumps, and it is important that the correct voltage and type is used when replacing a hot tub pump. What are some other factors to consider when replacing a spa pump? *Frame Size: This is how big the actual pump motor is. There are usually 2 sizes. A 48 frame pump motor is about 5 1/2 inches in diameter and has bolt hole spacing (between the through-bolts) of around 3 3/4 inches apart) while the 56 frame motor is larger at about 6 1/2 inches in diameter and has bolt hole spacing of around 4 1/4 inches between the mounting bolt holes. *Plumbing Size: Once the pump union has been taken off, measure the diameter of the outside diameter of the pump connector threads. For example measure the male fitting on the pump where the pipe was connected and it should be about 2 3/8" outside diameter for 1 1/2 inch plumbing or it will be the larger diameter of 3 inches outside diameter to indicate 2 inch plumbing. In rare cases if it measure say 3 5/8 inches outside diameter the pump may indicate 2 1/2 inch plumbing, but 1 1/2 inch or 2 inch plumbing are by far the most .mon plumbing sizes. There are some non-standard types of unions and fittings so contact your online pump vendor with any questions. Whether you need just Aquaflo pumps ,pump motors, pump impellers or pump seals, or need to replace an entire pump, getting a replacement pump is easy. Once you know the type of pump you have so that you order the same type of replacement pump. Find replacement hot tub pumps online at Canadas TheHotTubSuperstore.. About the Author: 相关的主题文章:
