ELECTRICAL SHOCK HAZARD UNIT MUST BE SAFETY GROUNDED, EARTHED.
DO NOT MODIFY, DEFEAT ELECTRICAL CONNECTIONS OR ALTER PLUG.
ELECTRICAL CONNECTIONS
BEFORE CONNECTING THE UNIT TO THE POWER SOURCE, VERIFY THAT THE
VOLTAGE AND PHASE OF THE POWER SOURCE ARE IDENTICAL TO THE VOLTAGE AND
PHASE INFORMATION ON THE DATA LABEL.
EARTHING INSTRUCTIONS
THE UNIT MUST BE GROUNDED. Grounding reduces risk of electric shock by providing an escape wire for
the electric current if an electrical short occurs. This unit is equipped with a cord having a grounding wire
with a grounding plug. The plug must be plugged into a receptacle that is properly installed and grounded.
Consult a qualified electrician or service agent if grounding instructions are not completely understood, or
if doubt exists as to whether the unit is properly grounded.
DO NOT USE AN EXTENSION CORD. If the product power cord is too short, have a qualified electrician
install a three-slot receptacle (or the country specific receptacle for International Units). This unit should be
plugged into a dedicated circuit with the electrical rating as provided on the product data plate.
STACKING UNITS
The RFHU is designed to allow limited stacking capabilities. This section outlines how to safely stack the
holding unit.
TIP HAZARD! DO NOT STACK RFHU-42 OR
RFHU-34 UNITS. DO NOT EXCEED 2 HOLDING UNITS
PER STACK. DO NOT PLACE HOLDING UNIT STACKS ON
SURFACES THAT MAY EASILY TIP OVER.
Place bottom unit into position then stack the next unit
on top. The top of the lower holding unit rests inside of
the base of the upper unit.
Step 1
Remove the base pan from the unit that will be on top. The pan
is held in place by four screws on the bottom of the unit.
