2.0 INSTALLATION INSTRUCTIONS
GENERAL
The PS-3E and PS-6E steamers are single compartment electric pressureless steam cookers
with an internal electric steam generator that maintains standby water temperature at
approximately 205°F. PS-3E is rated 10 kW. PS-6E is rated 15 kW.
At high altitude locations a lower temperature is required to achieve atmospheric steaming.
Contact your authorized service office to have the thermostat adjusted if the steamer will be
operated at high altitudes.
UNPACKING
This steamer was inspected before leaving the factory. The transportation company assumes
full responsibility for safe delivery. Immediately after unpacking the steamer, check for possible
damage. If the steamer is found to be damaged after unpacking, save the packaging material
and contact the carrier within 15 days of delivery.
Prior to installation, verify that the electrical service agrees with the specifications on the
machine data plate which is located on the left side panel.
LOCATION
Allow space for plumbing and electrical connections. Minimum clearances are 0" on the sides
and 6" (152 mm) on the back for proper air circulation. Allow adequate access for operating
and servicing the steamer, 36" (915 mm) at the front of the steamer and 15" (381 mm) above
the steamer.
LEVELLING FEET (Standard) OR 4" ADJUSTABLE LEGS (Optional)
Thread the four 2" levelling feet shipped in a bag inside the steamer cabinet into the threaded
holes on the bottom corners of the steamer. Or, thread the four optional 4" adjustable legs into
the threaded holes on the bottom corners of the steamer.

2.0 INSTALLATION INSTRUCTIONS (Continued)
LEVELLING
Using a spirit level or pan of water in the bottom of the steamer, adjust the levelling feet or the
feet on the adjustable legs to level the steamer front-to-back and side-to-side. After the drain is
connected, check for level by pouring water onto the floor of the compartment. All water should
drain through the opening at the back of the compartment cavity.
ANCHORING STEAMER (Without Legs)
1. Place steamer in the desired location on the levelled counter top and mark four corners.
Remove the steamer and drill ½" holes as indicated in Figure 1.
2. Apply a bead of RTV or other equivalent sealant around bottom perimeter edge of the
steamer. If anchoring the steamer, this bottom seal is necessary to meet NSF
requirements.
3. Set steamer on counter and bolt down securely with 3/8 - 16 bolts (not supplied).

2.0 INSTALLATION INSTRUCTIONS (Continued)
The water supply inlets are provided with 3/8" (10 mm) compression fittings for 3/8" O.D.
copper tubing. The water supply line pressure should be 25 - 50 psi (170 - 345 kPa) for each
line. The water supply to the generator tank is separate from the water supply to the cooling
system where steam is condensed before entering the drain line.
Install line strainers (not provided). A manual shutoff valve for each supply line must be
provided convenient to the steamer.
We recommend treated water feeding the boiler inlet supply, and untreated water feeding the
cooling system inlet. Hook-ups are labelled on the back of the steamer.
ADJUSTMENT FOR HIGH ALTITUDE LOCATIONS
The steamer has been factory set so that when it is ON, and during the READY phase, it will
maintain water temperature in the steam generator tank at approximately 205°F (96°C) (just
below water boiling point). However, for high altitude locations, an authorized service agency
must adjust the steamer to achieve this temperature.
ADJUSTMENT FOR DRAIN WATER TEMPERATURE
Cooling solenoid valves have been adjusted to yield drain temperatures of 140°F. This will vary
depending on install location water supply temperature and pressure. A qualified service
person should adjust the cooling solenoid valves should the drain temperature be other than
desired. Refer to section 7.0 Service on page 26 for adjustment instructions.
DRAIN CONNECTIONS (FIGURE 2)
The drain connection (Fig. 2) must be 1" IPS down, preferably with one elbow only, maximum
length of 6 feet and piped to an open air gap type drain. Use copper only.

WATER QUALITY
The water supply connected to this steamer should contain no more than 2.0 grains of
hardness per gallon with pH from 6.5 to 8.0. This degree of hardness and pH can easily be
obtained with the use of a properly maintained water softener.
Water supplies vary from one location to another. A local water treatment specialist should be
consulted before installing any steam generating equipment.
Untreated water contains scale producing minerals which can precipitate onto the surfaces in
the boiler. Due to the temperatures in the boiler, the minerals can bake onto the surfaces and
components. This can result in early component failure and reduced product life.
Mineral scale on components causes several problems:
1. The surfaces of the heating devices become coated with scale, reducing the heat transfer
efficiency. This can produce hot spots on the heating elements and result in premature
failure.
2. The water level probes become coated with scale. Scale will bridge across the probe
insulator from the metal extension which senses the water level in the boiler. Once this
scale becomes wet, the water level control is unable to maintain the proper water level in
the boiler. This situation may cause an electric heating element to fail if the element is not
adequately covered by water.
Strainers and filters will NOT remove minerals from the water.
Refer to REMOVAL OF LIME SCALE DEPOSITS, page 23.
VENT HOOD
Some local codes may require the steamer to be located under an exhaust hood. Information
on the construction and installation of ventilating hoods may be obtained from Vapor Removal
from Cooking Equipment, NFPA standard No. 96 (latest edition).

3.0 OPERATION (Continued)
CONSTANT STEAM COOKING - This mode will give continuous steam to the cooking
chamber until the operator either turns the timer to the “OFF” position, or turns power OFF to
the steamer.
When cooking is complete, or not in use, the constant steam cooking feature should be shut
off. This prevents the boiler from running unnecessarily. This will help conserve water, and will
reduce boiler maintenance.
SHUT DOWN
Turn the timer to OFF. Turn main power switch to the “OFF” position.
DRAINING THE BOILER
Drain the boiler after each day’s use to flush out minerals and minimize scale build-up. The
boiler drains automatically for approximately 4 - 6 minutes after the main power switch is turned
off.
Each compartment is equipped with a removable drain screen. Frequently
check the drain screen for accumulation of food particles. Should food
particles accumulate against, or clog the drain screen, remove it, clean it
thoroughly and then replace it in its original position.
Frequently check that the compartment drain and plumbing is free of all obstructions. Never
place food containers, food or food portion bags in the cooking compartment in such a way that
the compartment drain becomes obstructed.

3.0 OPERATION (Continued)
STEAM COOKING
Your steamer efficiently cooks vegetables or other foods for immediate serving. Steam cooking
should be carefully time controlled. Keep hot-food-holding-time to a minimum to produce the
most appetizing results. Prepare small batches, cook only enough to start serving, then cook
additional amounts to meet demand. Separate frozen foods into smaller pieces to allow more
efficient cooking.
Use a pan cover for precooked frozen dishes that cannot be cooked in the covered containers
in which they are packed if they require more than 15 minutes of cooking time. When a cover
is used, approximately one-third additional cooking time is necessary.
Cooking time for frozen foods depends on amount of defrosting required. If time permits, allow
frozen foods to partially thaw overnight in a refrigerator. This will reduce their cooking time.
PREPARATION
Prepare vegetables, fruits, meats, seafood and poultry normally by cleaning, separating,
cutting, removing stems, etc. Cook root vegetables in a perforated pan unless juices are being
saved. Liquids may be collected in a solid 12 inch by 20 inch pan placed under a perforated
pan. Perforated pans are used for frankfurters, wieners and similar items when juices do not
need to be preserved. Solid pans are good for cooking puddings, rice and hot breakfast
cereals. Vegetables and fruits are cooked in solid pans to preserve their own juices. Meats
and poultry are cooked in solid pans to preserve their own juices or to retain broth. Canned
foods may be heated in their opened cans (cans placed in 12 inch by 20 inch solid pans) or the
contents may be poured into solid pans.
ACCEPTABLE PAN SIZES
The steamer accommodates combinations of 12" x 20" pans, solid or perforated.

5.0 CLEANING (Continued)
Weekly, or more often if necessary:
Clean exterior with a damp cloth and polish with a soft dry cloth. Use a non-abrasive cleaner to
remove discolorations.
CAUTION: An obstructed drain can cause personal injury or
property damage.
GUIDELINES FOR MAINTAINING STAINLESS STEEL SURFACES
There are three things that can break down stainless steel and allow corrosion to develop:
1) Abrasion;
2) Deposits and water;
3) Chlorides.
Avoid rubbing with steel pads, wire brushes, or scrapers that can leave iron deposits on
stainless steel; instead, use plastic scouring pads or soft cloths. For stubborn stains, use
products such as Cameo, Talc, or Zud First Impression. Always rub parallel to polish lines or
with the grain.
Hard water can leave deposits that promote rust on stainless steel. Treated water from
softeners or certain filters can eliminate these mineral deposits. Other deposits from food or
lubrication must be properly removed by cleaning. Use mild detergent and non-chloride
cleaners. Rinse thoroughly. Wipe dry. If using chloride containing cleaners or sanitizers, rinse
repeatedly to avoid stainless steel corrosion. Where appropriate, apply a polish recommended
for stainless steel (such as Benefit or Super Sheen) for extra protection and lustre.

6.0 MAINTENANCE
WARNING: Disconnect the power supply to the appliance before
cleaning or servicing.
CAUTION: Live steam and accumulated hot water in the
compartment may be released when the door is opened.
CAUTION: The appliance and its parts are hot. Use care when
operating, cleaning and servicing the appliance.
COLD WATER CONDENSER
The steamer is equipped with a cold water condenser in the rear of the cooking chamber which
helps to condense the steam prior to discharge into the drain. The steamer freely vents itself
by the negative pressure created by the condensate water drainage. This negative pressure
prevents steam leakage around the door gasket and helps draw the steam through the cooking
compartment. Steam leakage at the door may indicate a plugged or improperly installed drain.
REMOVAL OF SCALE DEPOSITS
It is recommended that your steamer be delimed once a month, or more often if necessary.
Should your steamer develop a heavy buildup of lime scale deposits, use CLR.
Before beginning deliming procedures, ensure that water is not overflowing into the cooking
compartment.
The generator tank has a removable sealed tank cover. The main purpose of the removable
cover is for inspection of the interior of the tank for lime build up and easy removal of large
pieces of lime that will not flush out drain. Should the tank cover have to be removed, check
condition of sealing gasket before replacing cover. The hold down bolts are to be tightened to
160 inch pound torque each.

7.0 SERVICE
NOTICE: Contact the factory, the factory representative or local service
company to perform any maintenance and repairs.
ADJUSTMENT FOR HIGH ALTITUDE LOCATIONS
The steamer has been factory set so that when it is ON and during the READY phase, it will
maintain water temperature in the steam generator tank at approximately 205 degrees
Fahrenheit (just below water boiling point). However, for high altitude locations, an authorized
servicer must adjust the steamer to achieve this temperature. To adjust:
1. Remove side panel and turn control panel power switch to ON.
2. Open compartment door, and after about 15 minutes, steam will be seen, entering the
cooking compartment.
3. Turn thermostat dial counterclockwise to lower temperature until steam just ceases to enter
cooking compartment and READY light goes on.
4. Replace side panel.
5. Follow TESTING PROCEDURES in this manual.
WATER FLOWS INTO DRAIN DURING SHUTDOWN
When steamer is shut down and cold water is running continuously into the open drain, either or
both solenoid valves did not close when steamer was turned off.
1. Disassemble solenoid valve(s) and examine for scale or foreign particles lodged in
diaphragm or core tube.
2. Clean valve(s) thoroughly and reassemble, or replace valve(s).
DRAIN WATER TEMPERATURE TOO LOW OR TOO HIGH
Cooling solenoid valves are adjustable with fine adjustment screw on the bottom of the valve.
1. Run cooking compartment empty until drain temperature stabilizes.
2. Turn fine adjustment screw on cooling solenoid valve out to decrease drain temperature and
in to increase drain temperature.

7.0 SERVICE (Continued)
WATER OVERFLOWS INTO COOKING COMPARTMENT
When steamer is first turned on for the day, and the following conditions occur:
- READY light does not come on after about 15 minutes,
- Water begins to overflow into cooking compartment,
- Water fill solenoid valve is open,
then any or all of these symptoms may indicate a problem with the operating probe due to
either:
1. A short between the operating probe terminal and body of the steamer. Call your
authorized servicer.
2. Excessive scale build-up on the operating probe. This acts as an “insulation” and prevents
the probe from sensing the water level. It is therefore unable to close the water fill
(solenoid) valve to shut off the water.
As a temporary solution, with power OFF, unscrew probes, check visually, and clean or chip
off scalant. Replace probe.
This problem is an indication of severe harmful water conditions which should be corrected
immediately to avoid damage to the components and ultimate malfunction of the steamer.
(See WATER CONDITIONING in this manual).
HEATER ELEMENTS DO NOT COME ON
When the steamer is turned ON and heater elements do not activate, and therefore, the
READY light does not come on, then the contactors may be burned out. If a considerable
amount of “chattering” of contactors has been previously experienced, then the thermostat bulb
may be coated with scalant and unable to sense water temperature in the boiler accurately, and
therefore unable to control the contactors.
