box in an attic or any location 
where ambient temperatures 
may exceed 140 °F (60 °C). 
•  Do not locate control box next

NOTICE
Locating the Control Box
Determine the desired location of the ChromaSteam3 control box outside 
the steam room in a dry location.
IMPORTANT NOTE: 
The ChromaSteam3 control cable is 30 feet long. 
Ensure that the ChromaSteam3 fixture and control box are located accord-
ingly. Contact MrSteam to purchase an optional 60-foot cable (PN104268-60). 
Installing the Control Box
Using screws and washers, affix the control box to a stable vertical surface 
(e.g., stud) using the mounting holes on either side of the control box 
(Figure 4). 
•  The control box must be mounted in a vertical position as shown in 
Figure 4 to allow proper heat dissipation. Failure to mount as shown 
may cause thermal protection shut off.
•   To prevent product or property damage, do not expose control box 
to temperatures above 140 °F (60 °C). Do not locate control box in an 
attic or any location where ambient temperatures may exceed 140 °F 
(60 °C). 
•   In the event the control box requires servicing, ensure that it is  
installed in an accessible location.
IMPORTANT NOTE: 
The following materials (not included) are  
recommended to install the ChromaSteam3 control box:
• Two #10 screws of appropriate length with round, truss, or pan head.
• Two washers with 0.5” outer diameter x 0.0625” thickness  
(12 mm outer diameter x 1.5 mm thickness).
