CENTURY V-GREEN AND V-LINK SAVE YOU MONEY

  • The Merits of Variable Speed Pool Pump Motors

    September 14, 2017REDUCE THE COST OF POOL OWNERSHIP AND HELP THE ENVIRONMENT BY UPGRADING TO A VARIABLE SPEED PUMP MOTOR

    In-ground residential pools in the United States consume around $1.5 billion in energy costs per year, making pool pumps one of the biggest energy users in a home. Single-speed pumps typically run at high RPM’s and around the clock, over-circulating water and wasting precious energy and money. A variable speed pump motor can circulate water at the minimum turnover rate for water quality at a lower RPM, thereby greatly reducing the energy needed by up to 80%.

    ENERGY SAVINGS

    For a relatively small investment, a variable speed pool pump motor can pay for itself in energy savings alone. The Pump Affinity Law can be used to explain the relationship between motor speed, flow rates, and energy consumption. As motor speed is reduced, the flow rate is as well. This relationship to energy consumption (watts) is not linear, though. When motor speed is cut in half, the flow rate is cut in half. However, the power consumption is reduced to 1/8 of the original consumption. Table 1.1 shows the dramatic energy savings associated with running a motor at lower RPM’s.

    States, such as California through its Title 20, have recognized the energy saving impact that variable speed motors can have on the environment. Variable speed motors are increasingly preferred by regulatory agencies, over single and two-speed motors, for their ability to conserve energy.

    Variable Speed Motor Energy Consumption

    CONVERTING FROM SINGLE SPEED TO VARIABLE SPEED

    Variable speed pump replacement motors can be installed on existing single-speed pumps. Upgrading to a variable speed motor is all that is necessary to convert pools into high-efficiency systems. Service technicians should select the variable speed motor that is appropriate for the size of pool, plumbing and pump. Installation is simple without the need for additional plumbing or wiring.

    OTHER BENEFITS

    The slower circulation rates of a variable speed pump equate to a noticeably quieter motor. Operating at lower speeds also lowers the temperature of the motor, extending the life of the motor. A variable speed motor’s totally enclosed fan cooled (TEFC) construction equates to a longer life and less maintenance compared to a traditional open drip proof design.

    The VGreen® line of variable speed replacement pump motors offer premium energy savings along with an integrated user interface with fully programmable schedules and overrides. The VGreen motors are available in 0.85, 1.65 and 2.70 total horsepower in square, C-face (round) and through bolt flanges. These energy savings can be quantified using the VLink® Wireless User Interface that connects the VGreen motor to mobile devices to set, adjust, and monitor pump motor schedules. The program flexibility allows the user to monitor and manage energy consumption as well as set custom overrides for parties and cleaning. The VLink Wireless User Interface works with both Android and iOS mobile devices. Energy conscious pool owners have the ability to wirelessly monitor and manage their VGreen pump motor anytime anywhere.

    Upgrading to a variable speed motor will lower the cost of pool ownership through energy savings of up to 80% without replacing the pump. These motors run cooler, quieter and last longer. Owning a pool with a variable speed motor just became more affordable and better for the environment.

ORENDA START UP PROCEDURE

 

 

 

 

 

 

 

ORENDA START UP PROCEDURE

5-Day Startup Guide: Specifics
Based on 10,000 gallons (37,855 L)
NOTE: Pre-dissolve all dry chemicals in water prior to adding to the pool. Never throw dry chemicals directly into the pool, and never allow chemicals sitting directly on pool surface.
Filling the pool after plastering has been completed
1. Tap water should have already been tested and the Orenda LSI calculator will have shown you how much calcium chloride [77% flake] and sodium bicarbonate will be needed to achieve:
1. Minimum of 300 ppm calcium hardness
2. Minimum combined Calcium + Total Alkalinity level of 400 ppm.
3. LSI between +0.20 – +0.50
2. Pre-dissolve the prescribed amount of calcium chloride in the Orenda Startup Barrel™ or 5-gallon buckets. If using the Orenda Startup Barrel™, place it on the edge of the pool.
3. Hook up as many hoses as possible (at least two spigots) to fill the pool and one dedicated hose for the Orenda Startup Barrel™, if applicable.
1. Make sure you use a clean rag or sock on the end of any hose in the pool to minimize turbulence and protect the surface from direct contact with the metal end of the hose. Be aware that hoses can leave marks on a new pool surface, so try to keep them from making direct contact with the pool walls by using floats (like empty water bottles taped to the hose).
4. Turn on all the water to fill the pool. The dedicated hose to the Orenda Startup Barrel™ should be a gentle, steady flow of water, which will overflow the calcium-rich water into the pool. DO NOT turn the hose on full blast through the barrel.
5. When there are just a couple of inches of water in the pool, pour Orenda SC-1000 startup dose (one quart per 10,000 gallons) down the vacuum hose of the barrel into the pool. Alternatively, you can add SC-1000 directly if wearing the appropriate sponge footwear.
6. Ensure all valves and connections on the Orenda Startup Barrel™ are sealed and working properly before leaving.
Pool with Spa
1. Fill the spa with water before filling the pool.
2. Add 4 oz of Orenda SC-1000 to the spa (and catch basins/troughs if the pool has a vanishing edge)
3. When the spa has a few inches of water in it, dissolve one pound of calcium in a bucket and pour into the spa when cooled.
4. Gently stir the water in the spa (without spilling the water over the spillway if there is one).
Day 1: Once the pool is full of water
1. Fire up the equipment and begin circulation.
2. Brush vacuum (NOT wheeled vacuum) the entire pool and spa to get any residual dirt/debris off the surface.
3. Check water chemistry (after you brush vacuum). Input test results in the Orenda LSI Calculator App. Keep LSI between +0.20 – +0.50.
4. Adjust alkalinity with sodium bicarbonate if needed. Adjust pH to 7.5-7.8
5. Do NOT add salt or cyanuric acid for 30 days. Do not add chlorine until day 3.
6. Brush pool and spa thoroughly before leaving.
Days 2-4
1. Check chemical levels. Maintain an LSI between +0.20 – +0.50.
2. Add non-stabilized chlorine on Day 3, no more than 3-5 ppm. Again, do NOT add cyanuric acid or salt for the first 30 days.
3. Brush pool and spa thoroughly before leaving.
Day 5
1. Test water chemistry and adjust the LSI down to 0.0 – +0.3 using the Orenda LSI Calculator App.
2. Add one quart of Orenda CV-600 or CV-700 enzymes.
3. Brush the pool and brush vacuum (not a wheeled vacuum).
4. The pool should be ready for the homeowner to take over at this point.
Day 30
1. Add CYA and/or salt if necessary. Keep CYA level below 30 ppm.
Additional Information Disclaimer
The Orenda Startup Barrel™ should only be operated by a pool industry professional.
These are Orenda Technologies recommendations but we are not liable for the use of calcium chloride and/or the build out or purchase of fill tanks.
Calcium chloride in water gets extremely hot and can cause burns.
Appropriate eye and skin protection should be worn while handling chemicals.
Use at your own risk and liability.
