Food Rethermalizing Requirements

Warranty:

All Hubbell Model JFR booster heaters are backed by a full 1 year parts/labor warranty and additional 4 year tank warranty.

For a Food Rethermalizer:

Minimum of 2000 watts per square foot

(2.2 watts per square cm) of vessel top.

For a Bain-Marie or Steam Table:

Minimum of 750 watts per square foot (0.8 watts per square cm)

of vessel top. Units over 6' long require a minimum of two JFR heaters.

Baffle Information:

The JFR must be installed with a perforated water baffle.

This baffle is not supplied with the heater.

The JFR should be positioned with no more than 3' (91.4 cm)

on either side when mounted in the holding vessel.

Note: Product failure caused by liming or sediment buildup is

not covered under warranty.

Water Quality Requirements:

Incoming water in excess of 3.0 grains of hardness per gallon (GPG)

(.75 grains of hardness per liter) must be treated and softened before

being supplied to hot water dispenser(s). Water containing over

3.0 GPG (.75 GPL) will decrease efficiency and reduce the longevity

of the heater.

Options:

Security Package (Includes Torx

screws and digital display cover)

Step 1

Step 2

Voltage-Phase:

1Φ Voltages

RS = 208 - 1

S = 240 - 1

W = 277 - 1

T4S = 480 - 1

3Φ Voltages

R = 208 - 3

T = 240 - 3

T3 = 380 - 3

T7 = 415 - 3

T4 = 480 - 3

T6 = 600 - 3

Notes:

• All three phase JFR models are designed with balanced loads.

• The Hubbell JFR is suitable for cold or pre-heated water use.

NSF Standard 4 requires, for products manufactured for the purpose of rethermalizing food, that the food reach a safe serving temperature of

165°F in two hours or less in order to be listed to the NSF4 standard. The Hubbell model JFR is designed specifically for food rethermalizing, but

only in conjunction with a hot water bath rethermalizer. Hubbell supplies neither the vessel nor the system that determines how food is placed and

held in the vessel. The Hubbell JFR only supplies hot water to the vessel. Each vessel must pass its own NSF performance requirements and

although Hubbell provides sizing recommendations to help correctly size the JFR to the vessel, there are many variables involved in the

manufacturing of the vessel that impact its ability to pass the NSF requirements. The Hubbell JFR is ETL and ETL Sanitation (ANSI NSF 4) listed

for construction only. It is the responsibility of the manufacturer of the vessel to have the complete rethermalizing product tested and listed to the

NSF 4 Standard once the JFR is installed onto the vessel.
