Frymaster FBRA18 Series manual Incoming Gas Pressures

After the unit has been positioned in the area where it will be used, ensure the following has been accomplished before connecting the unit to the gas supply:

1.Adequate means must be provided to limit the movement of this equipment without depending upon the gas line connections. If a flexible gas hose is used, a restraining cable must be con- nected at all times when the equipment is in use.

2.The rethermalizer must be stabilized by installing restraining chains on units equipped with cast- ers or anchor straps on units equipped with legs. Follow the instructions shipped with the cast- ers/legs to properly install the chains or straps.

3.Level rethermalizers equipped with legs by screwing out the legs approximately 1 inch then ad- justing them so that the rethermalizer is level.

4.For rethermalizers equipped with casters, there are no built-in leveling devices. The floor where the rethermalizer is to be installed must be level.

5.Connect the water hose to the fitting at the rear of the unit.

NOTE 1: The hose comes with a quick-disconnect coupling. The quick disconnect may be at- tached to the rethermalizer or to the water supply line, or it may be left off entirely, whichever you prefer. Whichever of the options is chosen, Teflon thread-seal tape or Loctite™ PST56765 or equivalent thread sealer must be used when installing the fittings.

NOTE 2: Either hot or cold water may be connected to the unit. Connecting to hot water will minimize the amount of time required to bring the unit to boil when filling with fresh water.

NOTE 3: In order for the water level sensors to work properly, a certain amount of mineral con- tent in necessary in the water. For that reason, purified, deionized, or highly filtered water should not be used.

4.Connect the desired drain plumbing to the 1¼” drain valve.

5.Test the equipment electrical system by plugging the power cord into a grounded 120VAC outlet and pressing the controller’s ON/OFF button. After four (4) seconds, the last programmed set- point temperature will display constantly.

6.Turn the controller off. Verify that the display is blank.

7.Verify that the minimum and maximum incoming gas pressures for the type of gas to be used are in accordance with the accompanying table.
