OPTIONAL NIGHT AIR CURTAIN INSTALLATION & OPERATING INSTRUCTIONS

Night Air Curtain Installation & Operating Instructions

1. Use caution when handling Night Air Curtain.

2. Display case may come with Night Curtain already attached. If not, a retrofit kit
will be provided. If using the SCC-supplied retrofit kit, the Night Air Curtain
Support must first be attached to the existing Upper Front Duct Plate (see
illustration below). To attach, use the Night Air Curtain Support (as a template) by
placing it along the Front Duct Plate. Mark locations of existing Ø.20” hole onto
Upper Front Duct Plate. Drill clearance holes for #10 screws at these points.

3. Place Night Air Curtain Support into position and use the SCC-supplied screws to
attach it to the Upper Front Duct Plate (where pilot holes were just drilled).

4. Night Air Curtain Assembly may now b e placed on the Night Air Curtain Support.
Carefully positioned magnets will keep in place. Grasp the handle and pull
downward to desired location (see illustration below).

5. To return Night Air Curtain to its retracted position, grasp handle, lift up and away
from its magnetic attachment and carefully wind Night Air Curtain back into roll.

6. Caution!

Do not allow spring-loaded Night Air Curtain to freely snap back into roll.

Doing so can eventually destroy Night Air Curtain’s tension and retractability.

arising out of this Agreement or relating to the Goods after one year from the date of the breach. In the interpretation of this limitation on action for a breach by SCC, it is
expressly agreed that there are no warranties of future performance of the goods that would extend that period of limitation herein contained for bringing an action.

Indemnifications. Purchaser agrees to indemnify, hold harmless, and defend SCC if so requested, from any and all liabilities, as defined herein, suffered, or incurred by SCC
as a result of, or in connection with, any act, omission, or use of the Goods by Purchaser, its employees or customers, or any breach of this Agreement by Purchaser.
Liabilities shall include all costs, claims, damages, judgments, and expenses (including reasonable attorney fees and costs).

Remedies of SCC. SCC’s rights and remedies shall be cumulative and may be exercised from time to time. In a proceeding or action relating to the breach of this Agreement
by Purchaser, Purchaser shall reimburse SCC for reasonable costs and attorney’s fees incurred by SCC. No waiver by SCC of any breach of Purchaser shall be effective
unless in writing nor operate as a waiver of any other breach of the same term thereafter. SCC shall not lose any right because it has not exercised it in the past.

Applicable Law. This Agreement is made in Michigan and shall be governed by and interpreted according to Michigan law. Any lawsuit arising out of this Agreement or the
Goods may be handled by a federal or state court whose district includes Muskegon County, Michigan, and Purchaser consents that such court shall have personal
jurisdiction over Purchaser.

Miscellaneous. If any provision of this Agreement is found to be invalid or unenforceable under any law, the provision shall be ineffective to that extent and for the duration of
the illegality, but the remaining provisions shall be unaffected. Purchaser shall not assign any of its rights nor delegate any of this obligations under this Agreement without
prior written of SCC. This Agreement shall be binding upon and inure to the benefit of SCC and Purchaser and each of their legal representatives, successors and assigns.

SCC warrants its products to be free of defects in materials and workmanship under normal use and service for a period of one (1) year from the date of delivery.
This warranty is extended only to the original purchaser for use of the Goods. It does not cover normal wear parts such as plastic tongs, tong holders, tong cables, bag

holders, or acrylic dividers.
General Conditions. All service labor and/or parts charges are subject to approval by SCC. Contact the Customer Service Department in writing or call 231-798-8888.
All claims must contain the following information: (1) model & serial code number of equipment; (2) the date and place of installation; (3) the name and address of the agency

which performed the installation; (4) the date of the equipment failure; and (5) a complete description of the equipment failure and all circumstances relating to that failure.
Once the claim has been determined to be a true warranty claim by SCC’s Customer Service Department, the following procedure will be taken: (1) replacement parts will be

sent at no charge from SCC on a freight prepaid basis; (2) reimbursement for service labor will be paid if the following conditions have been met— (a) prior approval of ser­vice agency was awarded from the Customer Service Department; and (b) an itemized statement of all labor charges incurred is received by the Customer Service Depart­ment. The cost of the service labor reimbursement will be based on straight time rates and reasonable time for the repair of the defect.

If problems occur with any compressor, notify SCC’s Customer Service Department immediately. Any attempt to repair or alter the unit without prior consent from the
Customer Service Department will render any warranty claim null and void. This warranty and protection plan does not apply to any condensing unit or any part thereof which
has been subject to accident, negligence, misuse, or abuse, or which has not been operated in accordance with the manufacturer’s recommendations or if the serial number
of the unit has been altered, defaced, or removed.

Limit of Liability. The limit of liability of SCC toward the exchange cost of the original condensing unit, F.O.B. SCC, Norton Shores, MI, of each motor-compressor assembly
replaced during the warranty shall not exceed manufacturer's current established wholesaler’s exchange price and in no case shall the labor of removing or replacing the
motor-compressor or parts thereof be the responsibility of SCC.
