Need help?Do you have a question about the Davey QB Series and is the answer not in the manual?
The Davey QB Series Spa Pool Pump is a high-quality product designed for circulating swimming pool and spa water, ensuring reliable and efficient performance. This pump is specifically engineered to meet the conditions set out in the Australian Standard for swimming pool water quality (AS 3633) or equivalent. It is not intended for other purposes without prior consultation with a Davey Dealer or Customer Service Centre.
The primary function of the Davey QB Series pump is to circulate water in spa pools and swimming pools. It consists of a matched motor and a "pumping end" that work together to provide dependable operation and deliver maximum water flow. The pump is designed to maintain water quality by continuously moving and filtering the water, which is crucial for hygiene and the effective distribution of sanitizing agents.
The pump should be installed in a safe, dry, and well-drained environment, high enough to prevent flooding. It is recommended to locate the pump as close to the water source as practicable to optimize performance. The installer or owner is responsible for ensuring the pump's nameplate is easily readable and accessible for service. Adequate drainage around the pump enclosure is essential in case of leakage.
The QB Series pumps are supplied with barrel unions designed to connect to 50mm PVC pipes. The pipe should fit inside the union tail. Using pipes smaller than 50mm PVC pressure pipe is not recommended. Suction piping must be free from air leaks, humps, and hollows to prevent suction difficulties. Both suction and discharge pipes should have a constant, gentle slope of at least 2% to facilitate proper air purging. Barrel unions should be hand-tightened without the need for sealants, glues, or silicones. If the pump and filter are located below pool water level, isolating valves must be fitted in the pipe between the pump and the skimmer box or suction inlet, and in the return pipe from the filter to the pool.
Davey QB Series pumps are suitable for connection to a nominal 240 volt 50Hz power supply and come equipped with a flex lead and a 3-pin plug or AMP plug for connection to a Davey Spa controller. If a power outlet is not available within 3 meters of the pump, a 3-pin power point in a safe, dry place may need to be installed by an electrician. Extension cords are considered unsafe around pools or spas and should be avoided. If the supply cord is damaged, it must be replaced by the dealer or manufacturer using genuine Davey spares. The pump is double insulated to the water circuit, and an equipotential bonding point is provided if required by local electrical wiring standards. All installations should be fitted with earth leakage or residual current protection devices for safety. Power connections and wiring must be carried out by an authorized electrician, adhering to AS3000 wiring rules or local wiring standards. An easily accessible electrical isolation switch should be located to allow the pump to be switched off in an emergency.
To ensure efficient operation and prevent damage, a free flow of water to and from the pump is critical. Before starting, ensure all pipework is correctly sealed, the pool/spa water level is at the correct height, and all appropriate valves are open, with no obstructions preventing water flow. The pump must be primed by ensuring it is below the spa pool's water level. Connect the pump to the power supply or spa controller and switch it on. Allow the pump to run to expel any trapped air. If a strong flow of water is not established within one minute, switch off the pump and repeat the priming procedure.
The water level of the spa or spa pool should always be maintained at least to the spa jets, ensuring the pump always contains water. It is crucial never to run the pump dry, as this can damage mechanical seals, leading to leakage and flooding, and such damage is not covered under warranty.
If removal is necessary, switch off power and unplug the pump. If hardwired, a qualified electrician must remove the wiring. Close water valves on the pool return and pump inlet. Remove discharge and suction barrel unions, ensuring o-rings are not lost. Move pipework with unions attached to clear the pump. When making inquiries, always quote the model number from the nameplate.
It is recommended that the pump be protected from the weather to prolong its lifespan and maintain performance.
To maximize the life of your pool equipment and ensure personal safety, a weekly checklist should be followed, always turning the pump off first:
Maintaining balanced water chemistry is crucial for the longevity of your spa pool pump. The pump is designed for use with pool and spa water balanced according to the Langelier Saturation Index, with a pH level between 7.2 and 7.8, and regularly treated with a chlorine sanitizing agent not exceeding 3PPM. Regular water testing by a local pool shop is recommended.
Failure to undertake regular maintenance may cause damage not covered by warranty. Running the pump with no water (dry running) can damage mechanical seals, leading to leakage and flooding, and this damage is not covered under warranty.
