A. SAFETY

The Electric Rethermalizer operates on 230 volts single phase electrical power and NO
CLEANING OR REPAIR to any component should be attempted without FIRST disconnecting
electrical power. When in use the Rethermalizer will maintain water temperature above 150 F ˚
(66 C) which can cause severe ˚ burns. ALLOW METAL SURFACES TO COOL BEFORE

CLEANING THE RETHERMALIZER which can cause severe burns.

B. DESCRIPTION

The Electric Ultratherm 3 Rethermalizer was designed by Ultra­fryer Systems to operate as a commercial warmer to thaw, heat
and hold frozen products such as rice, macaroni and beans for up
to eight (8) hours. It is constructed from 16 and 18 gauge type
304 stainless steel with a #3 finish and is built as a table model.
The Model REO-1620 Electric Ultratherm 3 Rethermalizer is
equipped with a Thermostat, twin stainless steel chub baskets,
self-filling water float valve and a water overflow drain. The
Rethermalizer was designed to accommodate 12 Product Bags
simultaneously. Each chub basket may be divided into six (6)
compartments separated by the stainless dividers provided with the baskets. Embossed on the
Top Rim of the Rethermalizer are the numerals with 1-6 on the left and 7-12 on the right.

C: SPECIFICATIONS:

Water Inlet Pressure range is as follows: Min: 34.5 kPa (5psi)
Max : 930.8 kPa (135 psi)
Caution: Do not exceed maximum pressure.

30A243

A. INSTALLATION

1. Place the Rethermalizer in the location where it is to be operated.

2. Have a licensed plumber level the Rethermalizer and connect a 12" (13 mm) copper water line equipped ⁄

with a WATER SHUT-OFF VALVE to the WATER SOLENOID VALVE mounted to the rear of the
Rethermalizer.

3. NOTE: A provision for all pole disconnection from supply mains must be incorporated for fixed

wiring

NOTE: Water hardness may affect the performance and longevity of component parts coming

in direct contact with the water. Therefore, the local water supplier should be contacted
to determine if the water to be used with the appliance
should be treated with a filter, strainer, softener, and/or des­caler.

3. Have a licensed electrician perform the following:
a. Connect an CE approved 3 wire electrical cord

to the terminals inside the units electrical box shown to the

right:
b. Install an approved electrical plug on the electrical cord.
c. Install a “mating” rated electrical receptacle on the

wall behind the Rethermalizer operating location.
d. Connect the building ground to the ground lug located on the
outside of the unit.

4. Test the Rethermalizer as follows:
a. Ensure the controls listed below are in the proper position:

1. APPLICABLE CIRCUIT BREAKER IS ON

2. ELECTRICAL PLUG IS CONNECTED TO THE
ELECTRICAL WALL RECEPTACLE

CAUTION: ALLOW ALL METAL SURFACES OF THE RETHERMALIZER TO COOL PRIOR TO

PROCEEDING.

A. CLEANING

1. INITIAL CLEANING
A. Remove and THOROUGHLY wash the following items in a 3 compartment sink with
HOT water and soap, rinse these parts with HOT water and allow them to air dry:
STAINLESS STEEL CHUB BASKET
STAINLESS STEEL BASKET DIVIDERS
STAINLESS STEEL TUB GRILL

B. THOROUGHLY wash the Rethermalizer tub with HOT water and soap; then rinse the tub
with HOT water and allow it to air dry.

C. Wipe the top, side and front surfaces of the Rethermalizer with a HOT damp cloth.

D. When the chub baskets, dividers, grill and tub are dry, replace the grill , baskets and
dividers into the tub.

2. DAILY CLEANING
A.. Prepare a six (6) quart (5.7 liters) container of sanitized warm water, in the proper ratio, for
use in cleaning soiled surfaces.
B. Periodically throughout the day soak a cloth towel in the sanitized solution, wring out the
towel until it is damp and clean any soiled surface.
C. Perform the following routines at store closing:

1) Allow ALL metal surfaces and the water to COOL, remove the electrical plug
from the electrical receptacle, and CAREFULLY drain the water from the Rether
malizer tub.

2) Remove the two (2) Chub baskets, dividers, and grill from the Rethermalizer tub;
wash them with dish wash solution, THOROUGHLY rinse; and allow these items
to air dry.

3) Clean the Rethermalizer tub with dish wash solution, THOROUGHLY rinse and
allow it to air dry.

4) Clean all exterior surfaces with a reusable towel dampened with sanitizer and buff
dry.

5) Reassemble the Rethermalizer.

3. WEEKLY
A. Perform daily cleaning routines listed above.

B Place the Chub Baskets, Dividers, and Grill in a fryer with BOIL-OUT SOLUTION for
cleaning.
C. After the baskets, dividers, and grill have been cleaned ENSURE they are THOR-

OUGHLY sprayed with a solution of 1 PART vinegar to 25 PARTS water to NEUTRAL
IZE the boil-out solution; then allow these items to air dry.

D. Reassemble the Rethermalizer.

A. GENERAL

1. THERMOSTAT - The Model S-23-48 Robertshaw SPST Thermostat Temperature Dial can

be adjusted to heat water in the Rethermalizer tub from 60 F (16 C) to 212 F (100 C). The ˚ ˚ ˚ ˚
recommended COOK temperature is 180 F (82 C) and the suggested ˚ ˚ HOLD temperature is
180 F (82 C). The Thermostat is located on the backside of the front panel.˚ ˚

B. CONTINUED

ITEM ACTION RESPONSE

1 Ensure the Drain Valve

Lever is in the CLOSED
position; then OPEN the
water shut-off valve to the
Rethermalizer.

2 Turn the Toggle ON/OFF

switch to the ON position.

3 When the GREEN lamp

turns OFF, electrical power
will be applied to the ther­mostat to start heating the
water to 180 F (82 C).˚ ˚

THE RECOMMENDED HOLD TEMPERATURE IS 180 F (82 C).˚ ˚

4 When the RED heat ele-

ment indicator lamp turns
OFF indication the water is
at the desired HOLD tem­perature: 1) place the prod­uct to be cooked into the
appropriately NUMBERED
section of the Chub Baskets
Time the products corre­sponding to the numbered
sections.

A. Water will not begin to fill the tank until the solenoid valve is activated
by the toggle switch.

A. The AMBER power lamp will LIGHT.
B. The GREEN water flow lamp will LIGHT.
C. Water will begin flowing into the Rethermalizer tub.
D. When water reaches the fill level, the water flow will STOP. The

FLOAT of the Liquid Level Switch will shut off the solenoid valve and
the GREEN lamp will turn OFF.

A. The RED Heat Element Indicator Lamp will LIGHT indicating electrical

power has been connected to the heat elements to heat the water.

The HOLD time of that product will need to be activated on a timing
device.

B. When product is placed into the water, the water temperature will

DROP and the RED lamp will cycle ON and OFF, indicating the heat
elements are being turned ON and OFF to maintain water at the desired
HOLD TEMPERATURE.

Note: The rethermalizer is designed to thaw pre-cooked, pre-frozen product,
and HOLD the product until it is ready to be used once the product reaches
the holding temperature.

5 As the HOLD time for each

product expires:

6 Repeat steps 4 & 5 (above)

to cook additional products.

CAUTION: WATER LEVEL WILL DROP ABOUT 4" (102 mm) EVERY 4 HOURS DUE TO EVAPO-

RATION. VISUALLY CHECK THE RETHERMALIZER TUB PERIODICALLY TO AS­SURE WATER IS ABOVE THE HEAT ELEMENT AND THE PRODUCT IS BEING
HEATED OR HELD SATISFACTORILY.

A. Remove the product when ready

A. PREVENTIVE MAINTENANCE - Although the Rethermalizer only requires minimal preventive mainte-

nance, the need to keep it clean cannot be over-stressed. The food product comes in bags, but food may come
in contact with the inside of the unit and MUST be THOROUGHLY cleaned each evening. If the Rethermal­izer is kept clean and the following inspections are performed, this unit will provide many years of trouble free
service.
