INTRODUCTION
The One Shot Solid System combined with the Power Bowl Ultra will gravity feed a solid cleaning product into a
laundry machine or kitchen sink. The combined units are pre-mounted on a stainless steel mounting bracket for
mounting both units to a wall surface or side of the laundry machine.
INSTALLATION
Mounting:
Always install the system at a safe, convenient height for operators to load and unload solid containers. Using
appropriate hardware, mount the system high enough for the discharge line on the Power Bowl Ultra to gravity feed
into the sink or laundry machine.
For installations on laundry machines, mount the system above the supply compartment, or above the wash tub.
Plumbing:
The system includes a 28” coil of 1/4” OD poly tubing for the water connection from the dispenser’s solenoid to the
vacuum breaker on the Power Bowl Ultra (follow instructions included with the Power Bowl Ultra for installing the
vacuum breaker).
Check chemical manufactures specifications on water temperature and pressure. Usually 120 – 135 °F (48°-57°C)
at 18-25 PSI (1.2 – 1.7 BAR) is recommended.
Uncoil the poly tubing and insert one end into the push-connect elbow tube fitting on the discharge side of the
solenoid valve (to disconnect, push the tube up and hold the gray tab with your finger as you pull the tube out of
the fitting). Connect the other end of the tubing into the inlet side of the vacuum breaker on the Power Bowl Ultra.
Route the tubing as shown
and secure properly.
Use a 3/8” ID garden or utility water hose to connect the incoming water supply to the inlet side of the solenoid.
Slip the blunt end of hose over the brass barb and secure it with a hose clamp.

Optional Water Tempering Valve and Pressure Regulator Installation
We recommend the use of a water tempering valve and pressure regulator. Connect Tempering Valve and Pressure Regulator before the solenoid (see illustration below) The Tempering Valve will allow the water temperature to
be increased or decreased by turning the adjustment dial. The adjustment temperature is 120 to 160° F. The Pressure Regulator will regulate the water pressure from 0 to 60 PSI. Most manufactures recommend pressure of 18-25
PSI (1.2 – 1.7 BAR) at a temperature of 120-135° F (48-57° C).
Pressure gauge assembly can be purchased at your local hardware store (see parts list below)

OPERATION
Insert chemical container into the Power Bowl Ultra. Refer to One Shot and Power Bowl Ultra instruction manual for
programming and operation.
Run a few test cycles and inspect the operation of both the dispenser and Power Bowl Ultra to ensure proper
chemical feed is achieved. Check all plumbing for leaks.
CALIBRATION (of solid detergents)
As general rule of thumb program 10 seconds of run time for one ounce (28.3 grams) of detergent. For 2 ounces
(56.7 grams) set the run time for 20 seconds. Weigh the capsule (electronic scale may be needed) first then start
or signal the dispenser. Weigh the capsule again after the run time is completed. Then calculate amount dispensed. Run the capsule 2 or 3 times to see if the amount is consistent.
