52 Pa. Code § 56.292
The due date for payment of a deposit or any installment payment toward a deposit, other than a deposit required as a condition for the reconnection of service under § 56.291(2) (relating to general rule), may not be less than 21 days from the date of mailing or service on the customer of notification of the amount due. A customer may elect to pay a required deposit in three installments: 50% payable upon the determination by the public utility that the deposit is required, 25% payable 30 days after the determination and 25% payable 60 days after the determination. A public utility shall advise a customer of the option to pay the requested security deposit in installments at the time the deposit is requested. If the customer chooses to pay the deposit in installments, installment payments must be paid in full by the due date. Failure to pay an installment by the due date is grounds for termination of service as provided in § 56.321 (relating to authorized termination of service). The customer retains the option to pay the deposit amount in full before the due date regardless of any deposit installments previously paid.
