Requirements for Detergents and Sanitizers
Detergents
The PS-275 can use two types of detergents, one type for normal cleaning
and one type for “Deep Cleaning” for more effective deep cleaning. The
materials to be cleaned and the type of debris to be removed will be a
factor in selecting the proper detergent. Provide this information to a
chemical supplier when selecting the type of detergent. Use of the correct
detergent in the Power Soak machine is critical to its washing performance.
Improper detergents could damage the equipment. If there are problems
with cleaning results, please contact the Power Soak service department
888-994-7636.
The Power Soak PS-275 requires a low-foaming detergent
that is safe for human hands. The detergent should have
good grease cutting abilities but not have an excessively
high or low pH level. A metal/aluminum-safe formula is
recommended. Consult a chemical provider for a suitable
deep cleaning chemical.
Sanitizers
The method of sanitizing used in the Power Soak PS-275 is a "chemical
sanitizing" method. There are a number of products on the market that
work well in this application. A chemical sales representative should assist
in selecting the proper sanitizer. Ask the cleaning chemical provider to
determine detergent concentration, sanitizer "parts per million" (ppm) and
sanitizer submersion times to meet local health codes.
Power Soak Service Assistance
If a chemical sales representative is having difficulty selecting a detergent
or sanitizer, or if there are poor results with the chemicals that a
representative has recommended, please contact the Power Soak factory
at 888-994-7636.

the START button is pressed. If a cycle does not
start when the START button is pressed and
released, refer to the trouble shooting section.
(See page 8 for operating instructions)
STOP/IDLE Button
The red STOP/IDLE mode button is used to stop or
“pause” the wash action. The wash action will stop
when pressed. Some programming selections will
automatically resume the wash action after a short
period of time if the wash tank is not drained.
(See page 8 for operating instructions)
UNLOAD/LOAD Button
The UNLOAD/LOAD button is white with green up
and down arrows. It is used to indicate to the
program controller that the machine is receiving
proper attention when using the timed unload/load
wash cycle functions.
(See page 14 for operating instructions)
WASH TANK Light
The blue WASH TANK light is used to indicate
when the wash fluid needs to be changed.
SANITIZER TANK Light
The red SANITIZER TANK is used to indicate
when the sanitizer fluid needs to be either filled or
drained.

action to team members and managers. An optional wireless remote alert light
kit is available to repeat these messages in another part of the kitchen.
LED Beacons on the bottom of the
control panel.
Optional Wireless Remote Alert Lights
9
Blue Beacon
The blue beacon is used alone and in combination with
green and red to indicate action messages. Generally,
these messages have to do with the wash tank.
Green Beacon
The green beacon is used alone and in combination with
red and blue to indicate action messages. Generally, these
messages have to do with the timed unload/load cycle.
Red Beacon
The red beacon is used alone and in combination with
green and blue to indicate action messages. Generally,
these messages have to do with the sanitizer tank.
Orange Beacon
When the Deep Cleaning Mode is started the Orange
beacon will illuminate. It will flash when the water
temperature in the wash tank rises above 120F / 49C,
indicating the water temperature is hot enough to cause
scalding or burns. Use personal protective equipment to
avoid scalding or burns when the orange beacon is
illuminated.
10
Preparing the Machine
Filling the Machine
At the beginning of each day or shift, fill the tanks with water that is
metered to approximately the correct operating temperatures:
 Wash tank (115F / 48C)

Rinse tank (75F / 24C) – For Dip Rinsing Method

Sanitizer tank (75F / 24C)
All tanks should be filled to the “waterline” mark that is located in each
tank. Do not overfill the tanks; overfilling will cause the tanks to overflow
when items are added.
Be sure to adjust knobs on the spray rinse and all water
faucets so that the water temperature is below 120°F
(49°C). Temperatures higher than what is recommended
can cause scalding or burns if contact is made with a
person’s skin.
Wash Fluid
The method used to fill the wash tank (the wash tank contains the water
jets) will vary depending on how the chemicals are dispensed. The
following descriptions will describe the methods for filling and adding
chemicals to the wash tank.
Chemicals that are safe to touch when mixed with water
can be dangerous to touch in the concentrated form. Use
chemical resistant gloves and protective clothing when
handling concentrated chemicals. Consult the
manufacturers label for handling and safety information.
Direct Dispensing
Fill the wash tank using the faucet with water that is approximately 115F /
48C prior to adding chemicals. The hot and cold taps on the faucet are used
to adjust the water to the appropriate temperature. A good rule of thumb is
that the water should be hot to the touch but not so hot that it is
uncomfortable. When the tank is full, the chemical can be manually added to
the water when the wash pump has been started. Never place concentrated
11
chemicals into an empty tank. If the machine is equipped with the Power
Soak Chemical Dispensing system, the control system of the machine will
dispense the chemical when the wash pump is started. If your wash sink has
dual waterlines, fill to the upper waterline when washing sheet pans held in
racks and to the lower waterline for all other purposes.
Metered or Pre-Mixed Dispensing
If the machine is filled using a metered chemical dispensing system the
introduced water temperatures should be approximately 115F / 48C. The
hot and cold taps on the faucet can be used to adjust the water to the
appropriate temperature. Some machines are supplied with a set of mixing
valves that pre-mix the water to the correct temperature. The temperature
adjustments for these valves are located on the front of the valve. When
using a dispensing system, do not add water using the faucet. Water that
is added by a source other than the mixing system will dilute the chemical
solution and reduce its effectiveness.
Optional Wash Tank Filling Alerts
The PS-275 controller can help reduce labor and wasted chemicals in the filling
process by signaling that a wash tank fill is nearly complete. This allows an
operator to begin filling the wash tank, and return to other duties. When the tank is
within a few minutes of completing its fill, the blue and green beacons will flash in
an alternating pattern.
When the top liquid level sensor detects that the unit is full, the pattern will
speed up to communicate urgency that the water needs to be turned off.
Rinse Water
Submersion Rinsing
If the wares are to be rinsed by submersing them in fresh water, fill the rinse tank
(middle tank) with water that is approximately room temperature, 75F/24C. The hot
and cold taps on the faucet are used to adjust the water to the appropriate
temperature. Drain and refill this tank as necessary to maintain clean water in the tank.
Spray Rinsing
When using the faucet or hand held spray nozzle to rinse the wares, leave the wash
tank empty, with the drain open.
Sanitizer Water
Direct Dispensing
Fill the sanitizing tank using the faucet with water that is approximately 75F /
24C prior to adding chemicals. The hot and cold taps on the faucet are used to
12
adjust the water to the appropriate temperature. When the tank is full, the
chemical can be manually added to the water. Never place concentrated
chemicals into an empty tank. If the machine is equipped with the Power Soak
Chemical Dispensing system, the control system of the machine will dispense the
chemical when the wash pump is started.
Metered or Pre-Mixed Dispensing
If the machine is filled using a metered chemical dispensing system the introduced
water temperatures should be approximately 75F / 24C. The hot and cold taps on
the faucet can be used to adjust the water to the appropriate temperature. Some
machines are supplied with a set of mixing valves that pre-mix the water to the
correct temperature. The temperature adjustments for these valves are located on
the front of the valve. When using a dispensing system, do not add water using the
faucet. Water that is added by a source other than the mixing system will dilute the
sanitizing solution which will reduce its effectiveness and violate health codes.
Optional Sanitizer Tank Filling Alerts
The PS-275 controller can help reduce labor and wasted chemical in the filling
process by signaling the operator that a sanitizer tank fill is nearly complete. This
allows the operator to begin filling the tank, and return to other duties. When the
tank is within a few minutes of completing its fill, the red and green beacons will flash
in an alternating pattern.
When the top liquid level sensor detects that the tank is full, the pattern will speed up
to communicate urgency to turn off the water supply.
Manually Adding Detergents & Sanitizers
After the tanks have been filled with water, add the proper amount of detergent and
sanitizer. The detergent goes into the wash tank (the tank with the water jets) and
the sanitizer goes into the sanitizer tank (the tank furthest from the wash tank).
It is important to add the proper amount of chemicals to each tank. The amount to be
used should be provided by the chemical supplier. Do not add the detergent or
sanitizer to the tank prior to or during filling.
Most detergents and sanitizers lose effectiveness as time goes on. Some local
health departments have requirements limiting the amount of time water can be used
for cleaning before the water must be changed. Most chemical companies
recommend changing wash water after a certain time frame. Those times vary, but
are generally around two to four hours. Check with the chemical provider for
recommended time for effective use.
Sanitizing solutions also have a limited safe use period. Check with the chemical
provider on how often to check and or replace the sanitizing fluid.
13
Acceptable Normal Wash Chemicals:
 Chemicals must be safe for contact with human skin.
 The detergent must be low foaming, not excessively caustic and
metal/aluminum-safe are recommended.
 Cleaning solutions need to be selected for the type materials to be cleaned.
 Most standard sanitizers can be used with the PS-275, however; consult with
a chemical provider to be sure the chemical that is selected is a good choice.
Deep Cleaning Chemicals:
 Solid or liquid
 Matched to PPE of your company’s specifications.
 Consult with a chemical representative for proper PPE instructions.
14
Operating the Power Soak
Starting and Stopping the Wash Action
HOT WATER! Wash sink water can exceed 120°F (49°C).
Wear personal protective equipment to avoid scalding or
burns.
To start the wash action, press and release the green “START” button. A
strong “rolling” action should become present in the wash tank. When the
wash cycle is started the green STATUS light will change from flashing to
solid. When the STATUS light is solid, the wash fluid timer is timing down
to the next wash fluid change.
To pause the wash action, press the red “STOP/IDLE” button. This puts
the machine into an idle mode that stops the wash pump but continues the
wash timer. Some UPM program settings will automatically start the wash
pump and resume the wash action after a short period of time. For this
type of operation, the wash action cannot be completely stopped without
draining the wash tank. When the machine is in idle mode, the small
indicator light beside the Unload/Load button will be flashing. It will flash
faster and faster until the unit auto restarts.
Pressing and holding the START button for more than 8 seconds will start
the DEEP CLEANING CYCLE (see page 17). Note: if the START button is
held for more than 3 second, but less than 8 seconds, the wash motor will
not start. The button must be pressed again for less than 3 seconds to
start the Normal Wash or more than 8 seconds to start the Deep Clean
Mode.
Introducing Pots and Pans to the Power Soak
Dirty pots and pans should be brought to the Power Soak in a timely
manner. Do not allow items to sit and air dry. The quicker that items are
brought to the Power Soak, rinsed and put in the wash tank, the easier
they are to clean!
Properly Scrapping Pots and Pans
Excess soils should be removed from the pots and pans prior to dropping
them in the wash tank in order to reduce the amount of debris circulating in
the wash tank. Deposit the excess soils into a garbage can. Some
15
machines may have an optional pre-scrapping area with a pre-rinse spray;
soils may be deposited into the scrapper tray. Empty the scrap collection
tray regularly.
Loading and Using the Wash Tank
The Power Soak is a “random loading” machine. This means that Power
Soak items are not racked for washing. Instead, they are randomly loaded
one at a time and circulate in the wash tank. When items are brought to
the machine and the scraps removed, they should be immediately dropped
into the wash tank. The Power Soak is a “continuous motion” machine,
meaning that the machine does not operate on a set cycle time like a
cabinet-type washing machine. During normal operating hours where
washing is required, the machine is (normally) left running. The Power
Soak is energy efficient, and it does not cause excessive wear to leave it
running continuously. Typically, it takes between three to fifteen minutes to
wash items. Some heavily soiled or burnt-on items may take longer to
clean and should be allowed to circulate in the wash tank until they are
clean.
HOT WATER! Wash sink water can exceed 120°F (49°C).
Wear personal protective equipment to avoid scalding or
burns.
Rotating wares in the Power Soak PS-275 wash sink may
splash fluid from the sink creating a wet floor in front of the
Skewer Soak wash sink. Be aware that a wet floor may
cause a person to slip and fall creating a serious injury or
death.
Do not attempt to occupy any of the sinks on the Skewer
Soak machine. Be cautious not to fall into any of the sinks
on the Skewer Soak machine. The fluid depth is sufficient for
a person’s head to be submerged and cause a drowning
death.
Overloading
If there is no movement of items in the wash tank, or if items are stationary
above the waterline, the machine has been overloaded and some items
must be removed. It is very important not to overload the wash tank as it
reduces the effectiveness of the wash action.
16
Nesting
Some pots and pans stack for storage. This is referred to as “nesting”
when it occurs during a Power Soak wash cycle. Make sure that nested
items are separated and loaded one at a time. Nested items in the wash
tank will not be properly washed.
Unload/Load
The Power Soak tank does not have to be continuously monitored. There
are a couple of ways to manage the ware washing task using a Power
Soak.
Continuous Throughput
One way to manage labor with the Power Soak is through the process of
completing a wash cycle when an item is dropped off. When a ware is
dropped off the operator will:
1. Remove the scraps from the soiled item and drop it into the wash
tank.
2. Remove a clean item from the wash tank, rinse it and drop it into the
sanitizer tank.
3. Remove a sanitized item from the sanitizer tank and place it on the
clean drain board to air dry.
4. Remove a dry item from the clean drain board and place it in the
proper storage location.
By progressively moving items through these steps, a full wash cycle is
completed every time an item is dropped off. It should take only a minute
or two to complete the cycle and the Power Soak is not continuously
monitored.
Timed Unload/Load
The Power Soak PS-275 is equipped with programming and alert lights to
monitor the wash cycle. If enabled, this feature will time wash and
Unload/Load cycles and then signal the operator when it is necessary to
transfer the wares to the next step. The work flow should take place as
follows:
1. Drop off soiled items on a soiled landing area like the soiled drain
board.
2. Remove the scraps and fill the wash tank with a full load of items to
be washed. The program will time a wash cycle.
3. At the completion of the timed wash cycle the green beacon will
flash.
17
The flashing beacon indicates that the timed wash cylce has expired
and an unload/load cycle should be performed.
4. When an operator arrives to perform the unload/load cycle, they
should first press the Load/Unload
button on the control panel.
The green flashing beacon will turn solid to acknowledge the
operators action.
5. The dry, sanitized items should be moved to their designated
storage location.
6. All of the items should be removed from the sanitizer tank and
arranged for air drying on the clean drain board.
7. All of the clean items should be removed from the wash tank, rinsed
and placed in the sanitizer tank. When necessary some finishing
(light hand scrubbing) may be necessary.
8. Remove the scraps from a full wash load of items and place them in
the wash tank.
9. When these tasks are complete, press the Load/Unload
button
on the control panel. The solid green beacon will turn off to
acknowledge the completion of the unload/load cycle. The wash
timer will be started and the cycle will repeat. The operator may
return to other duties.
Between cycles, soiled items should be dropped off on the soiled drain
board or other soiled ware landing area.
Loading and Washing Utensils
Each PS-275 Power Soak machine comes with a utensil area that is a 6”
divided area in the wash tank. All utensils and other small wares should be
loaded into and washed inside this area.
18
Do not place knives or other sharp objects in the Power Soak.
Allowing knives or other sharp objects to tumble freely in the Power
Soak tank may cause bodily injury.
Knives and other sharp objects must be washed by hand with the
pump motor turned OFF. Wash, rinse and sanitize the knife or
sharp object, without letting go of the item and immediately place
the item into proper storage.
A fully loaded utensil basket can be very heavy. Unload the
basket prior to lifting the basket out of the sink. Do not
attempt to lift a fully loaded utensil basket. Attempting to lift a
fully loaded utensil basket can cause a muscle strain.
Rinsing Pots and Pans after Wash is Complete
Clean items that have been removed from the wash tank or utensil area
should be thoroughly rinsed. This is achieved by spraying them off or
dipping them in the (center) rinse tank. It is important that any remaining
detergent residue is removed from the items prior to sanitizing. If items are
rinsed by the "dipping" method, it is important to keep the water "fresh" by
frequently draining and filling the rinse tank.
Sanitizing Pots & Pans
After items have been properly rinsed they must be sanitized in the
sanitizing tank. It is necessary for each item to remain submersed in a
correctly titrated sanitizing solution for a specific amount of time. The
amount of time varies according to the type of sanitizer being used and
local health codes. Be sure to follow the chemical supplier’s instructions to
ensure that all items are properly sanitized.
Drying of Pots & Pans
After items have been sanitized, they should be thoroughly air dried on a
clean drain board or on adjacent drying shelves. Be sure to adhere to all
local health codes and recommendations for proper drying and stacking of
items.
Deep Cleaning and "Night Washing"
The Power Soak can be used as a "total cleaning system". Any item in the
operation that can be submersed for cleaning and is not fragile or sharp
can be washed in the Power Soak. Extremely soiled items and pieces of
cooking equipment that require regular, intensive cleaning can be washed
in the Power Soak machine overnight.
19
These are some examples of items that are typically deep-cleaned
overnight in the "Night Wash" cycle:







Hood Filters
Roasting Pans
Stove Tops
Frying Equipment
Stock pots
Carbonized items
Soiled storage racks
Many other items in the operation may qualify. Be creative and set up a
regular "Night Wash" program for improved sanitation. Items that have
been cleaned overnight should be removed, rinsed, sanitized (if necessary)
and put away or back in place. Sanitation supervisors should establish
standard operating procedures for items to be cleaned using the Night
Washing feature of the Power Soak.
Deep Cleaning Mode
HOT WATER! Wash sink water can exceed 120°F (49°C).
Wear personal protective equipment to avoid scalding or
burns.
The Deep Cleaning Mode can only be activated by completely draining the
wash tank below the low level sensor and refilling the wash tank. When
the START button is pressed and held for at least 8 seconds, the wash
pump motor will start when the program enters the Deep Clean Mode. If
the START button is simply pressed and released, the wash pump motor
will start and the machine will enter the “Normal Cleaning” mode that is
used for day time operation. If the normal cleaning is stopped within 30
seconds the machine can be re-started in the Deep Cleaning mode. After
30 seconds of operation, the mode is “locked in” and the tank will have to
be completely drained and refilled to start a different mode of operation.
When the pump motor starts in the Deep Cleaning Mode, the indicator light
on the control panel labeled “Deep Cleaning Mode Active” will illuminate.
(Note: if the START button is held for more than 3 second, but less than 8
seconds, the wash motor will not start. The button must be pressed again
for less than 3 seconds to start the Normal Wash or more than 8 seconds
to start the Deep Clean Mode.)
20
The Deep Cleaning Mode will elevate the water temperature to 128F /
53C which is higher than the normal daytime wash temperature (115F /
48C). When the Deep Cleaning Mode is entered, the orange beacon and
the control panel light that is labeled “High Wash Fluid Temperature” will
illuminate to indicate that the cleaning solution temperature is going climb
above the normal wash temperature. When the cleaning solution
temperature is raised above the control panel light and orange beacon will
flash. The flashing light and beacon will continue as a reminder that the
water is hot enough to cause scalding or burns. Personal protective
equipment are to be used for to avoid scalding or burns when the water
temperature is above 120F / 49C.
A different chemical may be beneficial for the deep cleaning cycle, see a
chemical supplier for recommendations on the type of chemical to use for
this type of operation. Solid or liquid chemicals can be used in the Power
Soak.
Since different chemicals are commonly used during the “Normal” daytime
operation and the “Deep Clean Mode”, the programming will not allow the
mode of operation to be changed until the wash tank is completely drained
and refilled. The 30 second “grace period” after the START button is
pressed allows the operator to verify the correct mode of operation. When
the “grace period” expires the PS-275 is locked into the mode of operation
until the wash tank is fully drained and re-filled.
The Deep Cleaning Mode will run the pump motor continuously for two
hours. At the end of the two hour cleaning period the pump will stop
continuous operation and start an intermittent cycle, ON for 5 minutes and
OFF for 10 minutes. Since the heating element only operates while the
pump motor is running, the cleaning solution temperature will be allowed to
cool down according to the program setting, no lower than 110F (43C).
The pump motor can be stopped and started during the continuous
operation of the Deep Clean Mode, however; pressing the STOP button
during the intermittent cycle (after the two hour wash cycle) will cause the
program to end the Deep Clean Mode and the pump will not start until the
wash tank is completely drained and re-filled. When a cycle has ended the
blue light on the control panel and the blue beacon will illuminate indicating
that the wash tank must be drained and re-filled.
1. Load the items to be deep cleaned into the Power Soak's wash
tank.
2. Drain the wash tank and start with a fresh washing solution by filling
the wash tank with clean water and the proper detergent for the
Deep Clean operation.
21
3. Press and hold the START button for at least 5 seconds.
4. Verify that the Deep Clean Mode is activated by observing the
illumination of the “Deep Clean Mode Active” light on the control
panel.
5. Leave the PS-275 to run. When the deep wash period is complete,
the deep cleaning period will automatically turn the wash action on
and off (cycle time is selected in the program settings).
Note: During the Deep Cleaning Mode, if sanitizer warning light should
illuminate, it will not affect the cleaning operation.
Changing the Wash Solution
The wash solution will need to be drained and refilled every four hours.
The control program will keep track of this time. 15 minutes before the
wash tank timer expires, the blue beacon will begin flashing.
The beacon will flash faster and faster until the timer expires. When the
timer expires, the wash action will stop and the blue beacon will become
solid.
This indicates that it is time for the wash fluid to be changed. The wash
action can be restarted for one minute using the START button to aid in
unloading the wash tank before draining. (This can be repeated five times)
Changing the Sanitizer Solution
In most cases, the sanitizer solution will need to be drained and refilled
typically every two hours or as advised by the chemical provider. In some
situations a chemical provider and local codes allow a different change
interval. When the sanitizer tank is filled a timer is started. 15 Minutes
before the sanitizer tank timer expires, the red beacon will begin flashing.
The beacon will flash faster and faster until the timer expires. When the
timer expires, red beacon will become solid.
If the program does not detect a solution change after a time, the wash
action will stop and the red and blue beacons will flash in an alternating
22
pattern.
Once this has happened, the wash pump is “locked out” and the only way
to restart the wash action is to drain and refill the sanitizer tank. The “lock
out” is a setting in the program that can be turned off.
Wash, Rinse and Sanitizer Clean-Up
Between each water change and at the end of each night, all tanks and
drain boards should be thoroughly cleaned with hot, soapy water. It is also
recommended to wipe down all the tanks and drain boards with a sanitizing
agent. Ask a chemical provider to recommend a sanitizer for this
application.

Preventive Mainenance
Preventative Maintenance
PS-275
24
The Power Soak PS-275 requires minimal, routine preventative
maintenance. The following procedures should be done to ensure that the
PS-275 remains reliable. If there are any questions regarding the
preventative maintenance procedures, please contact the factory at 888994-7636.
Daily
Clean the liquid level sensors that are located on the side
walls of the wash and sanitizer tanks. They are the white
plastic discs with metal centers. Clean the sensor faces
thoroughly. If cleaned regularly, a washcloth and soapy water
are all that is required.
If the liquid level sensors are not cleaned regularly, the
machine may fail to operate; or it may be possible to run
it without water, which will cause serious damage to the
unit.
Monthly
IMPORTANT: Turn off the power to the unit at the main
breaker prior to performing the following task!
Clean the pump motor fan shroud with a damp, soapy
cloth. The motor shroud is the "vented" cover located at
the end of the motor (closest to the control panel). This
will prevent grease and dust from accumulating in the
cover's openings, which can obstruct the airflow that
cools the motor.
Note: The motor bearings are permanently sealed and do
not need to be greased.
As needed
De-lime the wash tank. Simply add a recommended titration of de-liming
agent to a tank of warm, fresh water and run the machine overnight. Ask a
chemical sales representative to recommend a specific de-liming agent.

main electrical enclosure cover.
The cover to the enclosure must be properly closed before
reconnecting the power to the machine.
Explanation of LED Sequence
To verify the proper operation of the Power Soak machine, the operating
logic of the controls will need to be examined. This will require opening the
control box by removing the two screws on the face of the enclosure cover.
The Universal Programming Module (UPM) is mounted to the inside of the
control enclosure cover. The UPM has four LEDs mounted on its top edge.
The meaning of each LED is as follows, starting from the right-most LED:
1.
2.
3.
4.

Main power supply circuit breaker.
Fuse inside the control enclosure.
Bi-metallic disc switch for water temperature (switch must be closed
if water temperature is below 120°F)
Bi-metallic disc switch for motor temperature (switch must be
closed if motor temperature is below 150°F)
Check to see that the Liquid Level LEDs #3 and #4 are illuminated when
the wash tank is filled to the waterline.
Check to see that the Liquid Level LEDs #5 and #6 are illuminated when
the sanitize tank is filled to the waterline.
If any of the LED’s (3 thru 6) are not illuminated when the tanks are filled:
 Clean the liquid level sensors as described in the “Preventive
Maintenance” section of this manual.
 Be sure that all connections to and from the Liquid Level sensors
are secure and that there is no physical damage to the wiring.
 If damage to connectors and/or wiring is found, contact Power Soak
Systems, Inc. at 888-994-7636.
If the troubleshooting guidelines shown above do not correct the problem, it
will be necessary to contact Power Soak Systems, Inc. at 888-994-7636.
Prior to calling, please note the “Error Code” (if any) that can be identified
by observing LED #2 on the UPM and the “ERROR” green LED on the
front of the control panel. If there is a control logic error, the ERROR light
and LED #2 will flash with a “blinking” pattern. The definitions for the
patterns are as follows:
A “_“ symbol represents a “long” flash
A “.” symbol represents a “short” flash
_ _ _ . = Water Level Problem
_ _ _ . . = Temperature Sensor Problem
_ _ _ . . . = Over Current Problem
_ _ _ . . . = Over Temperature Problem
_ _ _ . . . . = Current Sensor Error
_ _ _ . . . . = Membrane Error
Note: If the Machine is flashing an error code, try having the service
person cycle the breaker for the Power Soak. Occasionally an unstable
power situation from the incoming power supply can cause a false error.
29
This type of error can be reset by turning the power to the machine off for a
few seconds and then turning it back on.
Please have the “Error Code” information available prior to calling Power
Soak Systems. The machine serial number will also be needed at the time
of the call.
The serial number is 5-6 digits long and
located on the lower corner of the wash
tank closest to the controller.

Installation & Decommissioning
PS-275
32
The installation and initial operational check of the Power
Soak Skewer Soak must be performed by licensed and
certified plumbers and electricians.
Be sure to follow all applicable national and local electrical
codes when installing the electrical supply and/or a new
breaker. DO NOT connect the system using a power cord
and plug or an extension cord of any kind.
Please refer to the detailed installation instructions that were sent with the
Power Soak PS-275.
Electrical Requirements
The electrical requirements of the PS-275 are on the serial number plate
located on the front corner of the wash tank, adjacent to the control panel
enclosure and inside the enclosure itself.
 All Power Soak machines have a single point electrical connection, and a
dedicated circuit is required. A ¾” seal tight conduct knockout is provided on
the rear of the control panel.
 The machine is completely pre-wired and tested at the factory, and a hardwired connection from an appropriate power source junction box is required.
 The installer is to provide a disconnect that should be incorporated in the
fixed wiring. Note: In areas where the walls are washed this should be a
waterproof style disconnect.
 Properly sized watertight conduit, fittings and parts are required, as well as
the appropriate gauge wire.
 If the machine is a “left-to-right” unit, the power source junction box should be
located at the left end of the machine. (The opposite would be true for a
“right-to-left” machine.) Ideally, the junction box should be located on the wall
directly behind the pump motor and control panel.
 If the machine requires 3 phase power, the motor rotation can be tested by
holding down the start button for 10 seconds, with no water in the machine.
This will momentarily rotate the motor to see the direction that it will be turning
when it is started. Verify the motor rotation matches the arrow on the pump
housing.
 A wiring diagram is located in the machine’s control panel enclosure.
 An equipotential bonding terminal is provided on the side of the wash
tank and identified with the symbol shown at the right of this statement. Symbol for
Bonding
Terminal
33
This terminal is used to make a connection for properly grounding the
machine. This connection must be completed by a qualified electrical
technician.
Specific part numbers and part information can be obtained from the factory
by calling 888-994-7636. Service information is also found on the Unified
Brands, Inc. web site (http://unifiedbrands.net).
Plumbing Requirements
The PS-275 requires the following plumbing connections:

One 3/4” (19mm) or 1/2” (12 mm) cold water supply line.

One 3/4” (19mm) or 1/2” (12 mm) hot water supply line.

One 3” (75mm) connection is recommenced for an in-floor main line.

One waste water connection minimum 1-½” (38mm).
Each tank will have a rear drain exit 1-½” (38mm) female threaded
connection that will have to be connected to the waste water
connection. Drain connection must not exceed elevations higher than
10-1/2 inches above the floor where the Power Soak machine is
located.
DO NOT USE HOSES to make the pressure connections to the
faucets. Maximum water inlet pressure is not to exceed 125 psi (8.6
Bar), minimum water pressure to be not less than 20 psi (1.4 Bar).
Decommissioning
When it is time to decommission the PS-275 the components of the
machine are to be recycled. The electrical control panel and motor
have materials that must not be discarded into common trash disposal.
Dispose of the control panel contents and the motor through a proper
waste electrical and electronic source or return the contents and the
motor to the source where the PS-275 was purchased.
The metal in the sinks and control panel enclosure has a value in the
recycled metals market. The owner of the PS-275 can recover this
value by directly contacting a metal recycling facility and making
arrangements to recycle the metal.
If any or all of the PS-275 is returned to the source where it was
purchased, there will be no obligation for the Power Soak
representative to make any compensation for the returned materials.
