Warranty/Section 1.2A |
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):

∙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

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.

The Basics:
1)Technicians should be authorized to work on Franke
Equipment and be EPA Certified and qualified to diagnose and repair refrigeration equipment.
2)The Franke Grill-Side Freezer comes in two sizes, the compact GSF-18 model and larger GSF-30 model.
3)Both GSF Models operate on 120-volt power and are provided with a grounded plug and 8’ power cord.
WARNING:
Unplug unit from its120-volt power source whenever servicing electrical components or removing the rear or side service access panels. Failure to unplug unit may result in electric shock, burns or death.
4)The GSF refrigeration system is charged with 18-20 ounces (.65 kg) of ozone-safe R404A refrigerant. See unit Data Plate and use site glass provided, when filling.
5)Only use R404A refrigerant when recharging this unit.
6)Always verify proper unit cleaning before replacing or repairing components. [See Section 4.1A]

2.2Front Freezer Door Gasket Replacement [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.

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.
