50 vs. 60 Hz
Step Up/Step Down Transformers ONLY convert voltage, they
do not convert cycles (Hz). Motorized appliances designed to
operate on 60 Hz may operate differently when used on 50 Hz
power sources. Check with the appliance manufacturer before
using a 60 Hz motorized appliance on a 50 Hz power source.
Motorized Appliances
At start up the current demand of a motorized appliance surges increasing the wattage required 50% to 200% above it's listed wattage rating.
OPERATING INSTRUCTIONS
1. Place the transformer on a firm, flat surface.
2.
Be sure the ON/OFF power switch is in the “OFF” position before
plugging (or unplugging) the power cord into a 110-120VAC or
220-240VAC power source. NOTE: In some countries a Voltage
Valet Grounded Adaptor Plug will be needed to connect to 220240VAC power sources (see grounded adaptor plug list).
3. Step Up Mode: Set the INPUT VOLTAGE SELECTOR switch
to 120VAC for use with 220-240VAC appliances in countries
with 110-120VAC power sources. Be sure your appliance
ON/OFF switch is in the “OFF” position and fully insert your
220-240VAC appliance plug into the 240VAC receptacle.
NOTE: Use grounded adaptor plug, model GUB, to modify
the 240VAC receptacle to fit most foreign 220-240 volt appliance plugs (except the South African 15 amp).
4. Step Down Mode: Set the INPUT VOLTAGE SELECTOR switch
to 240VAC for use with 110-120VAC appliances in countries
with 220-240VAC power sources. Be sure your appliance ON/
OFF switch is in the “OFF” position and fully insert your 110120VAC appliance plug into the 120VAC receptacle.
5. Turn the transformer's ON/OFF power switch to the “ON”
position. You are ready to use your appliance. NOTE:
the constant reversing of the AC current flowing through it,
this transformer may produce an audible hum when turned
on. This is normal and will not harm the transformer or any
appliance plugged into it.

MAINTENANCE AND CLEANING
DO NOT IMMERSE THE TRANSFORMER INTO WATER OR ANY
OTHER LIQUID.
1. Before cleaning, disconnect the appliance from the electrical

1. Do not leave unattended when connected to electrical outlet.
2. Always disconnect the transformer from the electrical outlet
3.
Close supervision is necessary when any appliance is used
—As with most electrical appliances, electrical parts
into bathtub or sink. If the appliance falls into water, UNPLUG
IT IMMEDIATELY. DO NOT REACH INTO THE WATER TO
RETRIEVE IT WHILE IT IS STILL PLUGGED IN. DO NOT USE
THE UNIT IF IT HAS BEEN IMMERSED IN WATER.
—To reduce the risk of burns, electrocution, fire, or
