NOTES:
• Severe or high cycle usage will require more frequent maintenance checks.
• It is suggested that while at the site voltage readings be taken at the operator. Using a digital voltmeter, verify that the incoming voltage to the operator it is within ten
percent of the operator’s rating.
Disconnect all power (AC, solar, battery) to the operator before servicing. The operator's AC Power switch ONLY turns off AC power to the control board and
DOES NOT turn off battery power. ALWAYS disconnect the batteries to service the operator.

BATTERIES
Batteries will degrade over time depending on temperature and usage. For best
performance, the batteries should be replaced every 3 years. Use only LiftMaster
part 29-NP712 for replacement batteries. The operator comes with two 7AH
batteries.
Two 33AH (A12330SGLPK) may be used in place of the 7AH batteries for a Large
Metal Control Box solar installation. A Battery tray (Model K10-36183) is required
for the 33AH application.
The batteries contain lead and need to be disposed of properly. Batteries do not
perform well in extremely cold temperatures.
The operator alarm will beep 3 times with a command if the battery is low.
