Idex Knight OS-200L Instruction Manual

THEORY OF OPERATION
The One Shot 200 is a dual product advanced microprocessor controlled injection system for dispensing a precise
amount of detergent and bleach into a domestic type top loading washing machine. The dispenser features two of the
KTM-500 timing modules, which includes a unique button programmable pump timer and pump "Lock-Out" time that
is designed to prevent consecutive dispensing where cost containment and control is required. The KTM-500 also
features a delay time function, and a "Relay Mode" which allows for a timed signal from a microprocessor laundry
machine to control the pump operation.
The dispenser is offered in three configurations: OS-200L – two liquid pumps, OS-200LS – one liquid pump and one
solenoid for solid product, OS-200S – two solenoids for two solid products. Other applications include pot and pan
detergent injection or detergent and sanitizer injection into a bar sink.
The OS-200 will activate when the signal input on the circuit board receives a 14-240VAC signal. An optional two
button remote switch box can be installed for a remote manual start. The OS-200 has a built in 120/208/230V
transformer for main power.
INSTALLATION
•
Mounting: Locate a spot near the laundry machine and use the provided hardware to mount the unit on the wall no
more than 8 feet from the floor and within 20 feet of the chemical supply. If using a remote switch box, ensure the
cable is long enough to mount the remote to the front of the washing machine.
•
Electrical: Connect main power to the 120/208/230V internal transformer. Use approved power cord and conduit
and install leads to appropriate voltage selection on the terminal strip on top of the internal transformer (refer to
wiring diagram). Wire the external signal from the signal source to the 14-240VAC signal input terminal. (refer to
wiring diagram). If using optional remote start switch wire the Orange and Red wires from the switch box to the
"START" terminals on Pump 1's circuit board and wire the Black and Brown wires from the switch box to the
"START" terminals on Pump 2's circuit board (refer to wiring diagram).
Note: When installing any electrical equipment insure that all the state and local safety codes are met.
•
Plumbing: Liquid product plumbing: Connect 1/4" OD tubing from the output (right) side of the pump to the point of
injection. Connect 1/4" OD tubing from the chemical source to the suction (left) side of the pump.
•
For solid chemical applications, an auxiliary feeder, such as the KNIGHT Power Bowl Ultra, is required to dissolve
the product and deliver it to the machine or sink. The solenoid will need to be plumbed into the feeder.
•
Solid product plumbing: Connect 1/4" OD tubing between inlet side of solenoid to the water source. Connect 1/4"
OD copper tubing between output side of solenoid to the input of the Power Bowl Ultra.
PRIMING
(1) Locate the dip-switch pack on the circuit board and set switch #6 to RELAY.
(2) Press and hold the Start button until the chemical line is fully primed, then release the button.
(3) Set switch #6 to SIGNAL (unless you intend to use relay mode).
CAUTION: Wear protective clothing and eyewear when dispensing chemicals or other materials.
Observe safety handling instructions (MSDS) of chemical manufacturers.
CAUTION: To avoid severe or fatal shock, always disconnect main power when servicing the unit.
