Aquasphere – VSP 100C Variable-Speed Pool Pump – 0.75 kW

The Aquasphere VSP 100C is a self-priming variable-speed pump for residential swimming pools, with a 0.75 kW motor and a maximum flow of 24.7 m³/h. Speeds can be selected from 450-3450 RPM, and it runs on 220-240 Vac, single phase, 50 or 60 Hz.

How the pump works

The Aquasphere VSP range is a self-priming range of pumps for residential swimming pools. Each pump uses variable speed technology with an embedded inverter and a user interface, so the speed can be matched to the job instead of running at one fixed setting.

The pump is designed for pre-filtering and recirculating clean water at temperatures not exceeding 35ºC. According to the manual, running at lower speeds can reduce running costs and noise levels.

Speed control and programming

Speeds are selectable from 450-3450 RPM using the buttons and display on the pump. The manufacturer describes the pump as easy to program.

• A default schedule is preset at the factory, and a custom schedule can be programmed.
• A Quick Clean setting runs a speed and duration of your choice.
• An optional priming program lets the installer set a priming speed and duration for a fresh installation. It is switched off by default.

The clock must be set when the pump is first installed. It also needs to be set again after a prolonged power cut.

Connections and pool water

The pump comes with a 1.7 litre pre-filter and D63 mm couplings. It is suitable for swimming pools that use electrolysis treatment.

Pool chemicals should not be stored near the pump, because fumes and spills can weaken pool equipment.

Installation

The pump is easy to install, according to the manufacturer. Installation and electrical connection are work for a qualified installer and must follow national wiring rules, local codes and the standards for swimming pool installations.

The manual asks for the pump to be fitted horizontally and fixed to a support, close to the pool, in a ventilated place protected from direct sun, heat and rain. Short, direct suction piping reduces friction loss and helps self-priming. The pump must not be run dry.

Care and maintenance

Before any maintenance or servicing, switch off the power supply and disconnect the pump from the mains. The pump should be connected to an earthed supply protected by a residual current device. If the unit develops a fault, the manual says not to repair it yourself but to contact a qualified service engineer.

Air trapped in the system can be dangerous, so make sure all air is out of the system before operating the pump. The manual also covers routine maintenance, troubleshooting and a freeze protection program.
