Venmar 40455, VT9W, 40355 Installation And Owner's Manual

INSTALLATION AND OWNER GUIDE FOR 40355, 40455 AND VT9W WALL CONTROLS

WARNING

IT IS RECOMMENDED TO WEAR SAFETY GLASSES AND GLOVES WHILE PERFORMING

THESE

INSTRUCTIONS. ALWAYS DISCONNECT THE UNIT BEFORE MAKING ANY

CONNECTIONS. FAILURE TO DISCONNECT POWER COULD RESULT IN ELECTRIC
SHOCK OR DAMAGE TO THE WALL CONTROL OR ELECTRONIC MODULE INSIDE
THE UNIT.

!

CAUTION

FAILURE TO COMPLY WITH THE FOLLOWING CAN CAUSE ERRATIC OPERATION OF

THE UNIT AND/OR THE WALL CONTROL:

N

EVER INSTALL MORE THAN ONE X-TOUCH MAIN WALL CONTROL PER UNIT.

MAKE SURE THAT THE WIRES DO NOT SHORT-CIRCUIT BETWEEN THEMSELVES

OR BY TOUCHING ANY OTHER COMPONENTS ON THE WALL CONTROL. AVOID
POOR WIRING CONNECTIONS. TO REDUCE ELECTRICAL INTERFERENCE (NOISE)
POTENTIAL, DO NOT RUN WALL CONTROL WIRING NEXT TO CONTROL CONTACTORS
OR NEAR LIGHT DIMMING CIRCUITS, ELECTRICAL MOTORS, DWELLING/BUILDING
POWER OR LIGHTING WIRING, OR POWER DISTRIBUTION PANEL.

WALL CONTROL INSTALLATION

WALL CONTROL COMPATIBILITY

REFER TO THE WALL CONTROL COMPATIBILITY CHART INCLUDED WITH THIS WALL CONTROL.

 UNPLUG THE VENTILATION UNIT FROM POWER SOURCE.

 CUT A 2 7/8” X 1 3/8” HOLE IN A WALL, AT A CONVENIENT

LOCATION FOR THE WALL CONTROL. ROUTE THE CABLE FROM
THE UNIT TO THIS HOLE.

NOTE: DIMENSIONS SHOWN ARE FOR AN INSTALLATION
WITHOUT WALL BOX.

 TEMPORARILY PLACE THE SWITCH OVER THE HOLE AND MARK

BOTH MOUNTING SCREW HOLE POSITIONS.

 REMOVE THE SWITCH, DRILL BOTH SCREW HOLES (3/16” Ø)

IN WALL AND INSERT WALL ANCHORS (INCLUDED).

 STRIP THE END OF THE CABLE TO ACCESS THE 4 WIRES.

STRIP THE END OF EACH WIRE. USING A SMALL BLADE
SCREWDRIVER, CONNECT EACH WIRE TO ITS CORRESPONDING
TERMINAL, ON THE BACK OF THE WALL CONTROL: YELLOW

WIRE TO “Y”, BLACK WIRE TO “B”, RED WIRE TO “R”,
AND GREEN WIRE TO “G”.

 MOUNT THE WALL CONTROL TO THE WALL.

P

LUG THE VENTILATION UNIT AND TEST THE WALL CONTROL
