Franke New Equipment

Limited Warranty & Service Commitment

Franke Foodservice Systems (“Franke”) warrants new equipment manufactured in Franke’s own facilities and installed in the United States and Canada to be free of defects due to poor materials or workmanship for the period of time listed below (following the date of original installation):

Franke-Manufactured Equipment

• Stainless Steel Surfaces – Life of the equipment

• Compressor -- 5 Year Extended Warranty, as detailed below

• All Other Components – 1 Years Parts and Labor

5-Year Extended Compressor Warranty

• One Year from Date of Installation – Parts & Labor

• 2nd through 5th Year from Date of Installation – Parts only

In accordance with the compressor manufacturer’s policy, the serial number plate affixed to the compressor must be returned with the service invoice before reimbursement will be made.

Exclusions. Certain Franke parts that are expendable by nature and that need to be replaced frequently may not be covered. Franke is not liable under these warranties for repairs or damages due to improper operation, attempted repairs or installation by unauthorized persons, alterations, water quality, abuse, fire, flood, or acts of God. Additionally, this warranty may be voided in the case of:

• Failure to follow Franke instructions for use, care or maintenance

Where such third party manufacturers provide warranties on any or all portions of said “buyouts,” Franke agrees to transfer all such warranties to the Buyer.

Rev. 2. 4/07

GSF Service Manual Service Commitment/Section 1.2B

The Franke Service Commitment

Franke Foodservice Systems’ Technical Support Department and its third-party Service Network are committed to meeting the unique service needs of restaurant operators. Accordingly, we strive to provide the following response times to service requests for Franke-manufactured equipment:

1. Provide contact with the customer…

– Within 30 minutes of request for service during normal business hours – Within 90 minutes after normal business hours (including weekends)

2. Perform service visit

– The same day for emergency service* – Within 24 hours for standard service

3. Target a 90% “first call” fix rate

4. Provide 90-day warranty on service performed

*For the purposes of this warranty, “emergency” is defined as an equipment operating condition that poses an immediate risk to the safety of restaurant workers or customers.

This response time breakdown applies throughout the week and weekend. Due to varying customer locations, and varying service agent locations and schedules, response rates may occasionally be extended. In these situations, Franke Technical Support will work directly with the customer to find mutually suitable options. Franke reserves the right to use service agents outside of the stated Service Network.

Service Network

United States and Canada

Franke supports and is a member of the National Service Cooperative (“NSC”), the leading independent provider of factory-authorized service in North America. Franke provides 24-hour, 7-days a week response to service requests through its own Call Center and that of the NSC.

Whenever possible, Franke selects service agents who belong to the Commercial Food Equipment Service Association. This trade association currently has more than 450 members representing the U.S., Canada, Mexico and Puerto Rico.

When Franke cannot select a CFESA member, it nonetheless adheres to the CFESA standard for qualified service agents in North America. Among them are:

• 24 Hour emergency service

• Factory authorized warranty service

• Factory trained and certified technicians

• OEM parts availability

• System for communication with field technicians

Performance of service agents, including their parts stocking abilities, call response time, service rates and customer satisfaction are monitored by the Franke Field Service Department via online, written and phone surveys. This Service Network list is updated annually by Franke Technical Support.

2.2 Front Freezer Door Gasket Replacement

[Photo 1]

[Model GSF-18 use Part No. 19000472] [Model GSF-30 use Part No. 19000473]

1) GSF Freezer should be unplugged and the freezer compartment fully defrosted before proceeding.

2) Open freezer door and inspect the one-piece magnetic door gasket. If the gasket is torn or crushed so that it doesn’t completely seal around the door perimeter, it should be replaced.

3) Remove top door hinge using a 7/16” [11 mm] box wrench or socket, being careful not to drop the door. Place door on a non-mar surface with the gasket side facing up.

4) Carefully remove the one-piece gasket from the slotted plastic extrusion built into the back of the freezer door. [Note: Plastic extrusion can be easily damaged. Using a razor knife to separate the old gasket from its retaining tailpiece may facilitate this procedure. Carefully remove the separated tailpiece from the slot by pulling toward each corner using small needle nose pliers.] See Photos 2 and 3.

5) Take the new gasket and insert the tailpiece into the gasket-mounting slot. Align the corners and start at the top of the door. Continue around the door perimeter until completely seated. [Tip: Place the door on a cushioned surface and carefully hammer the new gasket tailpiece into slot around the door perimeter. Be careful not to break the rubber tailpiece.]

6) Re-install freezer door on bottom hinge with bushing, then mount the upper hinge. Be careful to align the door before tightening the hinge mounting bolts.

7) Test the replacement of the Freezer Door Gasket by:

8) Close the door and visually check the door seal and fit.

9) Plug power cord into 120-volt outlet. Allow compressor to draw down Freezer Compartment temperature. Check with your hand around the full door perimeter for any leaks of cold air.

[Model GSF-18 use Part No. 19000474] [Model GSF-30 use Part No. 19000475]

1) GSF Freezer should be unplugged and the freezer compartment fully defrosted before proceeding.

2) Roll back top door, lift front edge and pull door clear of roller STOP depressions in freezer top.

3) Turn over door to gasket side, place door on a non-mar surface or the unit’s top, with the gasket side facing up.

4) Lift up inner edge of gasket material to expose plate/retainer screws. Use a large Phillips screwdriver to remove all the screws around the perimeter of the lid.

5) Lift retaining plate off gasket. It is OK to pry plate up with a large flat blade screwdriver or dull putty knife.

6) Take new one-piece door gasket [P/N 19000474 (GSF-

18) or 19000475 (GSF-30)] and position and align inside the rolling lid door.

7) Take inner door/gasket retainer plate and insert it under one side of gasket. Gently work around top, bottom and other side of plate, pulling gasket up and around plate. [NOTE: Avoid using sharp tools to lift or pry gasket material around the retaining plate.]

8) Make sure gasket retaining plate holes all line up, then insert and tighten all retaining screws.

9) Reposition the roll-back door on the freezer top with the two large plastic roller stop/guides to the case front.

Test the replacement of the Rolling Lid Door Gasket by:

10) Roll back the door to see if it moves freely. Release the door to see if it rolls forward unassisted and engages the roller depressions or stops.

11) Plug power cord into 120-volt outlet. Allow compressor to draw down Freezer Compartment temperature. Check with your hand around the front and sides of the door where it meets the top, for significant cold air leaks.

Lift roll-back door up and off GSF top and carefully place upside-down on freezer top.
