Multiple Faucets
Multiple faucets can be powered by a single transformer that has been properly
sized. Allow a minimum of 15 VA of current rating for each solenoid valve used.
Refer to the following example to determine the required current rating for 3
OPTIMA faucets.
Example:
Total number of OPTIMA faucets:
3
Total number of solenoid valves:
3
Multiply by current rating:
15 VA
——
Minimum current rating of required transformer:
45 VA

All Sloan transformers are 50/60 Hz.
Other transformers (not supplied by Sloan) may be used, provided they meet UL
requirements for Class 2 transformers.
Important: DO NOT supply power to primary side of Transformer until all
wiring has been completed.
Mount Transformer on a metal electrical junction box (supplied by others).
(“J” box should be mounted inside chase wall or above ceiling.) Install
Transformer within 50 feet (15.24 meters) of Faucet.
18 gauge wire is recommended.
A
Run wires from secondary side of Transformer to 3/8 inch (10 mm)
hole at back of Control Module Enclosure. If necessary, wires can be
run through wall and then inserted through hole in back of Control
Module Enclosure.
Important: DO NOT plug Transformer into receptacle until all wiring has been
completed.
The Transformer is supplied with a 10 foot Cable; however, this Cable can and
should be shortened to meet installation requirements.
A
Strip ends of Transformer Power Cable approximately 3/16 to 1/4
inch (5 to 6 mm).
B
Install Strain Relief 3 inches (76 mm) from one end of Power Cable.
Important: Twist stranded ends of Power Cable before inserting into Terminal
Block. Fraying of Stranded Power Cable Wire can cause a short and damage
the Control Module and Transformer when powered.
E
Install Crimp Connectors and connect Power Cable ends to
Transformer Terminals.
