Warranty Policies
Parts Warranty
Randell warrants all component parts of manufactured new equipment to be free of defects in material or
workmanship, and that the equipment meets or exceeds reasonable industry standards of performance for a
period of one year from the date of shipment from any Randell factory, assembly plant or warehouse facility.
Note: Warranties are effective from date of shipment, with a thirty day window to allow for shipment,
installation and set up. In the event equipment was shipped to a site other than the final installation
site, Randell will warranty for a period of three months following installation, with proof of starting
date, up to a maximum of eighteen months from date of purchase.
Component parts warranty does not cover glass breakage or gasket replacement. Randell covers all shipping
cost related to component part warranty sent at regular ground rates (UPS, USPS). Freight or postage incurred for any express or specialty methods of shipping are the responsibility of the customer.
Labor Coverage
In the unlikely event a Randell manufactured unit fails due to defects in materials or workmanship within the
first ninety days, Randell agrees to pay reasonable labor incurred. During the first ninety days work authorizations are not required for in warranty repairs. However, repair times are limited to certain flex rate schedules
and hours will be deducted from service invoices if they exceed allowed times without prior approval and a
work authorization number. Warranties are effective from date of shipment, with a 30 day window to allow for
shipment, installation and setup.
Where equipment is shipped to any site other than final installation Randell will honor the labor warranty for a
period of ninety days following installation with proof of starting date, up to a maximum of nine months
from date of purchase. Travel time is limited to one hour each direction or two hours per invoice. Any travel
time exceeding two hours will be the responsibility of the customer.
Note: Temperature adjustments are not covered under warranty, due to the wide range of ambient
conditions
Five Year Extended Compressor Warranty
United States installations only:
Randell will pay for the replacement compressor only. Freight, labor, refrigerant, handling and all other miscellaneous charges are the responsibility of the customer. Randell will fulfill its warranty obligation by using one of
the four methods provided below, which will be selected by the Randell in house service technician:
1. Provide reimbursement to servicing customer for the cost of the locally obtained replacement compressor in
exchange for the return of the defective compressor returned to Randell freight prepaid. Randell does limit
the amount of reimbursement allowed and does require a copy of the local supply house bill for replace
ment compressor.
Customer should not pay servicing agent up front for compressor.
2. Provide repair at the manufacturing facility by requiring that the defective unit be sent back to Randell freight
prepaid. Perform repair at the expense of Randell and ship the item back to job location freight Collect.
3. Furnish a replacement compressor freight Collect in exchange for the return of the defective compressor
sent back freight prepaid.
4. Furnish complete condensing unit or replacement package freight Collect in exchange for the return of the
defective compressor sent back freight prepaid. (decisions based on whether or not to send complete
condensing unit will be made by Randell in-house service technician).
Export Warranty
Our export warranties will cover all non electrical parts for the period of one year from the date of shipment to
be free of defects in material or workmanship. Electrical parts are also covered if ordered and operated on 60
Hz. Electrical components, ordered and operated on 50 Hz, are warranted for the first 90 days from shipment
only. Service labor is covered for the first 90 days with authorization from factory prior to service. Warranty is
automatically initiated 60 days from ship date. Inbound costs on any factory supplied items would be the
responsibility of the customer. Adherence to recommended equipment maintenance procedures, according to
the owners manual provided with each unit, is required for this warranty to remain in effect, and can have a
substantial effect on extending the service life of your equipment. Equipment abuse voids any warranty.
Extended warranties are not available for parts, labor or compressors on units shipped outside the United
States.
Freight Damage
Any and all freight damage that occurs to a Randell piece of equipment as a result of carrier handling is not
considered warranty, and is not covered under warranty guidelines. Any freight damage incurred during
shipping needs to have a freight claim filed by the receiver with the shipping carrier (note all damages on
freight bill at time of delivery). Internal or concealed damage may fall under Randell’s responsibility dependent
upon the circumstances surrounding each specific incident and are at the discretion of the Randell in-house
service technician.
Gasket Coverage
Randell does not cover gaskets under warranty. Gaskets are a maintenance type component that are subject
to daily wear and tear and are the responsibility of the owner of the equipment. Because of the unlimited
Unit Installation
A. Receiving Shipment
Examine the exterior of the shipping crate for signs of abuse. Partially remove the crate and examine the
cabinet for any possible concealed damages. If no damages are evident replace the crate. If the unit is
damaged note on the delivery slip or bill of lading and signed to that effect. A claim must be filed immediately
against the carrier indicating the extent and estimated cost of damage occurred.
B. Locating Your New Unit
The following conditions should be considered when selecting a location for your unit:
1. Floor and Countertop load - The area on which the unit will rest must be free of vibration and strong enough
to support the weight of the unit plus the maximum product load.
2. Clearance - There must be sufficient clearance on all sides of the unit to allow for efficient airflow.
3. Ventilation - The air cooled self contained unit requires a sufficient amount of cool clean air. Avoid placing
the unit near heat generating equipment such as ovens, ranges, heaters, fryers, steam kettles, etc. and
out of direct sunlight. Avoid locating the make table in an unheated room or where the room temperature
may drop below 13°C or above 32°C.
C. Electrical Supply
A properly wired and grounded outlet is required to assure proper operation. Please consult the data plate on
the compressor for correct electrical requirements. Supply voltage and amperage requirements are located on
the model and serial number tag.
Unit Operation
This unit operates with an electronic control which is factory set for optimal performance and then locked so no
adjustments are necessary. The numerical led display indicates the air temperature in the cabinet. If the
control senses an abnormality it will begin to display an error message which in some cases will alternate with
the temperature display. the error message “HA” (High Alarm) denotes that the temperature in the refrigerator
has been too high for too long. This condition could be casued by an open door, dirty coils, or a refrigeration
system problem. As soon as the temperature is back within the limits this alarm will end. The following table
lists the possible error codes and the suggested actions:
Preventative Maintenance
Randell suggests a preventive maintenance program which would include the following:
1. Clean condenser coils. Coils are a critical component in the life of the compressor and must remain clean to
assure proper air flow and heat transfer. Failure to maintain this heat transfer will affect unit performance
and eventually destroy the compressor. Clean the condenser coils with coil cleaner.
Note: Brush coil in direction of fins.
2. Clean fan blades.
3. Lubricate door hinges with lithium grease.
4. Clean and disinfect drain lines and evaporator pan with a solution of warm water and bleach.
5. Clean gaskets on a weekly basis with a solution of warm water and a mild detergent to extend gasket life.
NOTE: DO NOT USE SHARP UTENSILS WHILE CLEANING EQUIPMENT.
Proper maintenance of equipment is the ultimate necessity in preventing costly repairs. By evaluating each
unit on a regular schedule you can often catch and repair minor problems before they completely disable the
unit and become burdensome on your entire operation.
1. Cleaning condenser coil.
An accumulation of dirt and dust prevents the condenser coil from removing heat, making your unit cool poorly,
run constantly, or even stop completely if the compressor overheats. Clean coil using a vacuum cleaner with a
wand attachment. If the coil is greasy, wash it with warm soapy water and a bristle brush, taking care not to
drip water on other parts of your unit.
2.Cleaning drain and drain pan. Clean the drain using an oven baster to force a solution of hot water and
baking soda or bleach into the opening. To clear a stubborn clog, insert a length of ¼” round plastic tubing into
the drain and push it through to the drain pan, then pull it out. Wash the pan regularly with a solution of warm
water and baking soda.
