IMPORTANT
The steam pipe entry into the steam
room and the steam head must be
caulked to avoid damage caused
by steam leakage into the wall.
Centering the steam pipe is critical
through walls made of plastic,
acrylic, resin, fiberglass, or similar
materials. Allowing the pipe to touch
materials not rated for 212°F (100°C)
or higher will result in damage
to these materials.
If the steam line is in an area where the
temperature will be below 40°F (4°C) or
if the line is more than 20 feet (6 m) long,
insulate the steam line for best results.
SECTION 5: WIRING INSTRUCTIONS
1.
ELECTRICAL ROUGH-IN
Use correct size and type of power wires and circuit breakers to meet electrical codes. Leave 4 feet (1,2 m) of slack wire at generator location to finish hookup.
Connect each generator to a dedicated circuit breaker.
2
ELECTRICAL FINISH
At the generator, route the copper supply wire with an appropriate strain relief through the hole marked POWER ENTRY. Connect the supply wires to the power
terminal block. Refer to the wiring diagrams to determine your connection points and the necessary jumper connection. Connections can be varied to use either
single phase or 3 phase or 3 phase +Neutral. Connect the earth ground to the ground lug (green screw).
Notes
:
• Two power circuits are required for 208V WWSU11 and for 208 and 240V WWSU15.
• Supply voltage must be 200V or higher. 240V models may be used with available voltages to 240V (and 380V-415V~3N).
• Use copper power wire only! All wire is to be UL Listed, 300V 75°C minimum unless otherwise specified.
•
A GFI device is not required by UL or NEC. One may be installed if required by local codes or the owner.
A GFI device will tend to nuisance trip due to heater element aging.
3.
CONNECT STEAMERS TOGETHER
Connect a control cable from the Primary steamer’s G1 or G2 jack to the secondary steamer’s AK IN jack. Repeat for the third steamer, if installed. Note: We
recommend system steamers be of similar wattages and, if not the same, the largest wattage should be in the primary steamer.
