Normal household timers are not built to take the high inductive loads produced by HID ballasts. If used with an HID ballast - the contacts inside the timer that open and close the timed circuit will overheat and weld together - breaking the timer and leaving your grow lights permanently on. The PowerPlant Heavy Duty Timer is different.It is designed to take high loads and has no problem dealing with the inductive loads produced by a 600w ballast. It has a 96 switching operations within a 24 hour period (every 15 minues). This timer is suitable for timing one 600w HID ballast. It has a robust case design with socket and timer dust/moisture covers.
This unit is ideal for timing 400w and 600w ballasts. Do not use more than one 600w ballast per timer.
FAN, ALUMINIUM DUCTING, CARBON FILTER, CLAMPS X 3. Centrifugal fan - 110 m3/h - comes with stand attached to screw to floor (can not see in picture). To get the most out of your kit, please follow these few tips. Remember, if you reverse-mount your Filter you will lose the benefit of your pre-filter and reduce the life of the carbon. Always mount your filter as high as possible.
Hot air naturally rises and so will your odours! Try not to block too much of the filter with mounting straps or hanging devices. Use the ends of the filter to support, so not to inhibit the surface area of the filter. Do Not mount your Filter near to humidifiers. Humid air over 85% may enter the filter rendering the activated carbon ineffective and your filter may NOT neutralise odours!Ensure you have an airtight seal around the connection of your filter to ducting or extractor fan.
