HEALTHCARE

Welcome to Follett

Follett equipment enjoys a well-deserved reputation for excellent performance, long-term reliability and outstanding

after-the-sale support. To ensure that this equipment delivers that same degree of service, review this guide

carefully before you begin your installation.

Should you need technical help, please call our Technical Service group at (877) 612-5086 or (610) 252-7301.

Please have your model number, serial number and complete and detailed explanation of the problem when

contacting Technical Service.

Getting Started

After uncrating and removing all packing material, inspect the equipment for concealed shipping damage. All

freight is to be inspected upon delivery. If visible signs of damage exist, please refuse delivery or sign your delivery

receipt "damaged." Follett Customer Service must be notied within 48 hours. Wherever possible, please include

detailed photos of the damage with the original packaging so that we may start the freight claim process.

Product Loading Guidelines for Optimal Temperature Performance

Maintaining optimal temperature relies on good air circulation, which can be achieved by ensuring that the fan grill

and return vent are visible and by loading your refrigerator or freezer with 1” of clearance on the top and each side.

KEEP CLEAR 1" ON EACH SIDE AND TOP.

FAN GRILL AND RETURN VENT MUST BE VISIBLE.

SAFE ZONE - STORE PRODUCT WITHIN THIS AREA

Refrigeration System

The Performance Plus refrigeration system is designed to give many years of trouble-free service. Except for routine

cleaning of the air-cooled condenser and related parts, the refrigeration system requires no service or maintenance.

The system uses a capillary tube and is critically charged. The connection of refrigeration service hoses to the

ttings will almost invariably result in a signicant change in the system charge. This change can adversely affect the

performance of your refrigerator. Therefore, Follett recommends that if hoses are ever connected to the refrigeration

system for service, the refrigerant should be recovered, the system evacuated, and recharged by weighing in the

correct refrigerant charge.

Installing Glycerine Solution in Product Simulation Bottle

(glycerine not included - P/N00959296)

ATTENTION INSTALLER

§It is imperative that the top/bottom probe bottle be lled with a solution

that your facility uses to ensure proper operation of unit.

§Units are equipped with a third-party monitor installation port.

Customers are required to refer to CDC Vaccine and Handling Toolkit

(cdc.gov) for proper placement of the probe within the cabinet to

ensure proper performance.

§NSF 456 requires the temperature display probe to be replaced or

from the original date of calibration on the Certicate of Traceability

supplied with your equipment at the time of purchase. Recalibration

or purchasing a new calibrated probe is not covered by the original

equipment warranty. To purchase a new Probe with Certicate of

Traceability, please contact our Parts Department @ 1-877-612-5086 or

partsales@follettice.com

Operation

The temperature control board and probe indicate when the refrigeration system is required to turn on and off.

The refrigeration system removes heat from the cabinet interior and rejects it to the surrounding room air.

When the cabinet interior temperature rises above the controller cut-in temperature, the controller turns the

refrigeration system on. The controller energizes the evaporator fan and solid-state control relay which energizes

the condensing unit. The compressor uses a current-style starting relay and a starting capacitor to start the

compressor motor.

When the cabinet interior falls below the predetermined cut-out temperature, read by the P1 (control probe), the

controller de-energizes the solid state compressor relay and condenser fan motor. The additional evaporator fan

run-time is dependent upon the delay setting programmed within the controller menu.

Any accumulated frost on the evaporator coils melts during the off cycle. The condensate drains out of the unit

to the condensate tray to the left of the condensing unit. The heat from the condensing unit evaporates any

condensate in the drain pan.

Temperature Control

The temperature control system is preset by the factory to maintain a product temperature of 6C (42.8F). If

desired, the set-point temperature can be raised as high as 10 C (50F) by following the instructions in Controller

Operation on page 8 for changing the temperature set point.

Defrosting

Performance Plus undercounter refrigerators do not require manual defrosting. The unit cooler defrosts

automatically when the condensing unit is in the OFF cycle and during an off time defrost every 8 hours. The

defrost will terminate when the cabinet temperature read via the P1 control probe reaches 3.3 C (38 F) or after

60minutes.
