Frequently asked questions
How long should I run my pool equipment each day?
Run time is set by turnover - circulating the pool's volume through the filter - so it depends on pump flow and pool size, and it changes with water temperature. Longer run times are needed in warm weather when demand on the sanitiser is highest.
What is the part number for this control?
Intermatic lists this control under part number PF1103MT. Quote PF1103MT when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
Does this need to be wired by an electrician?
Timers and switches for pool equipment are wired into the supply circuit and are subject to electrical code, including GFCI requirements. Cut power at the breaker and use a licensed electrician if you are not confident identifying line and load.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Intermatic equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
Will this work with 120V and 240V equipment?
Check the voltage and load rating in the specification section above. Fitting a control rated below the equipment's voltage or amperage is a fire risk, and mismatched ratings are the most common installation error.
Is there a warranty on this control?
It carries the standard Intermatic manufacturer warranty. The terms are set by Intermatic, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
