Why is my SL300 beeping?

Helpfully, the SL300 diagnoses itself out loud, so you simply count the beeps. First, listen for a repeating pattern, because that signals a major fault. Then count the beeps, since the number tells you which fault it is.

However, beep codes 3 to 6 only apply if your model actually has those switches.

A single long beep is a minor fault

Meanwhile, minor faults reset themselves as soon as you clear the cause. Harmar lists five:

• Seat swivelled out of position
• Edge safety detected (SL300FR only)
• Footrest
• Current overload condition
• Low battery voltage condition

Why won’t the battery charge?

Because this is the fault that strands most stairlifts, page 14 of the manual repays a careful read:

• First, leave the lift switched ON. Otherwise the batteries simply will not charge.
• Second, park the chair within three feet of an upper or lower landing, so that it sits on the charge strip.
• Third, check the light on the chassis: solid green means fully charged, while solid amber means charging.
• Also, leave the power supply plugged in continuously, because the lift can stay on charge indefinitely.
• If the light flashes orange while the lift beeps intermittently, then check that the chair sits close enough to a charging station and that the charger is properly plugged in. Afterwards, move the lift to either end of the rail.
• However, if no light shows on the charger at all, the AC power adapter is probably at fault, and that one is a dealer call.

In addition, Harmar rates the batteries for roughly one to two years and asks a dealer to fit the replacements, because non-compliant batteries can cause malfunctions.

If someone is stuck on the lift

Page 17 documents a manual override, which raises or lowers the chair to a landing. Depending on your model, it uses either a ¼-inch or a 7 mm socket and wrench, which engages through the lower safety flap. However, read that page before you attempt anything, because the first instruction tells you to confirm the rider genuinely cannot get off on the stairway. Above all, getting it wrong with someone in the chair is worse than waiting. Therefore, if you are unsure, call us and we will talk you through it.

Registering and servicing

Harmar asks you to return the separate warranty form within ten days of purchase, and to let a dealer inspect the lift every one to two years. Furthermore, alterations without written authorisation from the manufacturer void the warranty. Finally, code requirements vary by state, city and locality, and the manual puts responsibility for meeting them on the installer — worth knowing especially if you inherited a lift with the house.
