The keeper shall take custody of the proceeds from all sales unless otherwise directed by the judgment creditor. (b) The levying officer shall take the tangible personal property into exclusive custody at the earliest of the following times: (1) At any time the judgment debtor objects to placement of a keeper in charge of the business. (2) At any time when requested by the judgment creditor. (3) At the end of 10 days from the time the keeper is placed in charge of the business. (c) Where a keeper is placed in a business for the purpose of taking into custody tangible personal property consisting solely of money or equivalent proceeds of sales, the provisions of subdivision (b) shall not apply, and the levying officer shall take such property into exclusive custody at the end of each daily keeper period.
