INTRODUCTION Page 1 Type JFR single-phase step-voltage regulators are designed to give dependable service and to make installation, operation and maintenance as simple as possible. QUALIFIED PERSON Technology advances, especially in the realm of the control apparatus, make it efficient to provide a separate instruction manual for the Accu/StatTM control provided with this JFR Regulator. For specific control information, refer to the Accu/StatTM control manual included with the regulator.
INTRODUCTION Page 2 INSPECTION FOR DAMAGE IN SHIPMENT STORAGE PRIOR TO INSTALLATION Check each item with the shipping manifest immediately upon receipt of the regulator. Make a thorough visual inspection of the regulator. Check for evidence of damage attributable to mishandling in shipment. Should any shortage or damage be found, notify the local agent of the carrier making the delivery and make appropriate notation on the freight bill. A claim should be made immediately with the carrier.
INTRODUCTION PHYSICAL CONSIDERATIONS • Handling. Type JFR regulators are designed to be lifted either by a forklift at the base or by use of hangar brackets on the side of the tank. Each JFR regulator is provided with either 2 or 4 lifting hooks on the side of the tank. The number of hooks has been established to provide a margin of safety on lifting when all hooks provided are used. WARNING Page 3 • For air cooled (OA) rating, derate kVA rating 0.

INTRODUCTION Page 5 PROTECTIVE MEASURES Bypass Arrester. All JFR regulators are equipped with a properly sized arrester, connected externally between the 'S' and 'L' line terminals. The arrester is provided to protect the series winding of the regulator from line surges. Of itself, the bypass arrester does not provide lightning protection for the regulator. Lightning Protection.

PLACING THE REGULATOR IN SERVICE Page 9 The following checks will be useful in assuring the regulator is ready for use. The list cannot be all inclusive; careful attention on the part of a qualified operator remains imperative. BEFORE CONNECTING WARNING High pressure or mechanical failure due to improper bypass operation can cause death, severe injury or damage. To prevent: • Check oil level at oil sight window. If low, add sufficient oil (ASTM D-3487 Type II) to bring level to that desired.
REMOVING THE REGULATOR FROM SERVICE Page 10 REMOVING THE REGULATOR FROM THE LINE In order to remove a regulator from service without dropping load, it is imperative that the regulator be on the neutral position. The system must first be de-energized (load dropped) before removal. If the regulator being removed is in a closed delta bank, it is necessary to bypass and isolate all regulators in the bank.
MAINTENANCE Page 11 GENERAL INSTRUCTIONS Failure to properly maintain the regulator can result in severe personal injury and product failure. The instructions contained herein should be carefully reviewed, understood and followed. The following maintenance procedures should be performed regularly: 1. Operational checks • Control performance • Tapchanger performance • Vari-AmpTM limit performance. 2.
MAINTENANCE Page 12 PERIODIC INSPECTION A sample of oil from the regulator should be subjected to dielectric breakdown test, per ASTM D-877. It is recommended that oil testing less than 24 kV be filtered. Other tests, especially Neutralization Number, Interfacial Tension and Power Factor are also useful and may be preferred by particular users. Contacts, both movable and stationary, show normal burning and wear after 1,500,000 operations.
SPECIAL FEATURES Page 13 POLARIZED DISCONNECT SWITCH (JACK PLUG) AND HINGED CONTROL PANEL The Accu/StatTM control panel is hinged and may be removed completely from the regulator control box by removing the wing nuts on the polarized jack plug and pulling the jack from its fixed portion. This will automatically de-energize the control. It is not necessary to bypass or de-energize the regulator to remove the control.
SPECIAL FEATURES Page 14 Catalog OPERATION AT LESS THAN RATED VOLTAGE JFR regulators may be operated at less than the voltage for which they were designed. All system voltages for which control system taps have been provided are shown on the nameplate. When this is to be accomplished it may be necessary to reconnect particular leads at the upper 19-pin terminal block as illustrated on page 5.
SPECIAL FEATURES Page 15 FORCED AIR COOLING SUBBASE ASSEMBLY Certain regulators may be equipped for forced-air cooling and include fans mounted on the radiators. The fans are usually automatically controlled by means of the change in oil temperature (see Connection Diagram). The thermometer located in the top transformer oil contains two identical switches which control fan operation when fan control switch is in “Auto” position.
