General

The Deluxe Food Warmer (steamer) produces a steam

using plain tap water for quick heating and reconstitut-

ing of food items. Simple push-button action delivers

a shot of water which is immediately converted into

steam. Because the amount of steam is consistent, it

removes the guesswork and produces a uniform fin-

ished product from one operator to the next.

This manual provides the safety, installation and oper-

ating procedures for the Deluxe Food Warmer (steam-

er). We recommend that all information contained in

this manual be read prior to installing and operating the

unit.

Your Deluxe Food Warmer (steamer) is manufactured

from the finest materials available and is assembled to

Roundup’s strict quality standards. This unit has been

tested at the factory to ensure dependable trouble-free

operation.

• Turn the unit off, disconnect the power source

and allow unit to cool down before performing

any service or maintenance on the unit.

• The procedures in this chapter may include

the use of chemical products. These chemi-

cal products will be highlighted with bold

face letters followed by the abbreviated HCS

(Hazard Communication Standard). See

Hazard Communication Standard manual for

the appropriate Material Safety Data Sheets

(MSDS).

• The equipment should be grounded accord-

ing to local electrical codes to prevent the

• WARNING ELECTRICAL SHOCK HAZARD.

FAILURE TO FOLLOW THESE INSTRUCTIONS

COULD RESULT IN SERIOUS INJURY OR

DEATH.

- Electrical ground is required on this appli-

ance.

- Do not modify the power supply cord plug.

If it does not fit the outlet, have a proper

outlet installed by a qualified electrician.

- Do not use an extension cord with this

appliance.

- Check with a qualified electrician if you

are in doubt as to whether the appliance is

properly grounded.

• This equipment is to be installed to com-

ply with the basic plumbing code of the

Building Officials and Code Administrators,

Inc. (BOCA) and the Food Service Sanitation

Manual of the Food and Drug Administration

(FDA).

• On direct water hook-up units, water pressure

must not exceed 30 psi (2.1 kg/cm2 or 207

kPa). Higher water pressures will cause poor

performance, excessive condensation, and

flooding of the Steam Generator. To reduce

water pressure, install a water pressure

regulator and set water pressure between

20-30 psi (1.4 - 2.1 kg/cm2 or 138 - 207 kPa).

Contact your equipment supplier to purchase

a Water Pressure Regulator.

• Do not clean this appliance with a water jet.

• Do not use a sanitizing solution or abrasive

materials. The use of these may cause dam-

age to the stainless steel finish.

• To ensure proper steaming characteristics,

some calcium/mineral deposits must be pres-

ent on the generator surface. If, during clean-

ing, the surface does become free of calcium/

mineral deposits, add plain tap water to the

surface and allow it to boil off. This may have

to be repeated several times to ensure proper

steaming characteristics by creating a thin

layer of deposits on the surface.

• Chlorides or phosphates in cleansing agents

(such as bleach, sanitizers, degreasers, or

detergents) could cause permanent damage

to stainless steel equipment. The damage is

usually in the form of discoloration, dulling

of metal surface finish, pits, voids, holes or

cracks. THIS DAMAGE IS PERMANENT AND

NOT COVERED BY WARRANTY.

The following tips are recommended for main-

tenance of your stainless steel equipment,

- Always use a soft, damp cloth for cleaning,

rinse with clear water and wipe dry. When

required, always rub in direction of metal

polish lines.

- Routine cleaning should be done daily

using soap, ammonia detergent and water.

- Stains and spots should be sponged using

a vinegar solution as required.

- Finger marks and smears should be

rubbed off using soap and water.

- Hard water spots should be sponged using

a vinegar solution.

Models DFW/DFWT-100/150

CAUTION

This equipment is to be installed to comply with

the basic plumbing code of the Building Officials

and Code Administrators, Inc. (BOCA) and the

Food Service Sanitation Manual of the Food and

Drug Administration (FDA).

The DFW/DFWT-100/150 models have a self-contained

water tank. To fill the self-contained water tank:

1. Open the sliding tank cover on top of the unit

(Figure 3).

NOTE: Make sure filter inside tank is installed

properly.

2. Pour in cold tap water. The tank will hold approxi-

mately 3 quarts (2.81 liters). Do NOT overfill the

tank.

3. Close the water tank cover.

Models DFW/DFWT/DFWF-200/250

These models require a direct cold water hookup. A

Water Inlet Hose and Strainer Assembly (Figure 4) is

supplied.

NOTE: Incoming water is controlled by a normally

closed (NC) solenoid valve located inside the

Steamer’s electrical housing.

1. Turn off the water valve (not supplied) that sup-

plies water to the unit (Figure 4).

2. Connect the 1/4” (6.5 mm) I.D. Flexible Tubing to

the outlet side of the Water Pressure Regulator

and secure using the worm clamp as shown in

Figure 4.

NOTE: A Water Pressure Regulator must first be

installed as shown in Figure 4. Failure to do so will

result in poor steaming and possible flooding. For

a single steamer, use Water Pressure Regulator P/N

7000314. For two adjacent steamers, use Water

Pressure Regulator P/N 7000235.

3. Turn the water valve on.

4. Over a bucket, press and hold the white plastic

tip on the Quick Disconnect Insert (Figure 4) until

good, steady water flow is noted (this will purge

all air out of the line). Release and note the pres-

sure on the Water Pressure Regulator gauge. It

should read 20-25 PSI. If it reads more or less,

adjust the pressure by pulling the black knob

upwards and turning it clockwise to increase or

counter-clockwise to decrease the water pressure.

Push the knob down to lock it in place.

NOTE: When adjusting the knob, you must relieve

the existing pressure by pressing the white plastic

tip on the Quick Disconnect Insert for 3 seconds.

This allows the newly set pressure to register on

the gauge. Repeat this until the gauge reads 20-25

PSI.

5. Push the Quick Disconnect Insert into the fitting at

the rear of the unit until a “click” is heard

(Figure 4).

CAUTION

Water pressure must not exceed 30 psi (2.1 kg/

cm2 or 207 kPa). Higher water pressures may

cause poor performance or flooding. To reduce

water pressure, install a water pressure regulator,

and set water pressure to 20-25 psi (1.4 - 1.7 kg/

cm2 or 138 - 172 kPa).

OPERATION

General Information

ALL MODELS

When the operate button (Figure 5) is pressed and

released, power is supplied to the water pump (Water

Tank models) or solenoid valve (Direct Water Hookup

models). The pump/solenoid operates and water

sprays onto the heated steam generator (Figure 9).

The water flashes immediately into steam and steams

the product.

TIMER MODELS - DFW/DFWT/DFWF–150/250

EXCEPT DFWF-250 WITH MFG. NO 9100147

On Timer Models, one of two operational modes can

be used: Single Shot or Timed Cycle

Single Shot

The Operate Button (Figure 5) is pressed and released

to initiate a single steam shot. The Control Board

applies power to the Water Pump/Solenoid and a “shot”

of steam occurs.

Timed Cycle

The control is used to set the desired steamtime (up

to 99 minutes, 59 seconds). When the Start/Stop

Button (Figure 5) is pressed, the Control Board applies

power to the water pump/solenoid at regular intervals

for the duration of the displayed cycle time. The dis-

play counts down to zero when the cycle is complete,

sounds an audible signal, and then reverts back to the

original programmed cycle time. The unit is ready for

the next cycle when the green ready light is on.

IMPORTANT: Timer Models are factory programmed

for the following recommended settings:

• Total Cycle Time = [15.00] (15 minutes)

(Range: 3 sec. to 99 mins 59 secs)

• Shot Interval Time (SHO) = [00:20] (20 seconds)

(Range: 3 secs to 5 mins 59 secs). 20 seconds is

recommended.

• Water Volume (H2O) =

WARNING

To avoid injury, be careful when opening top

cover. Be sure to allow steam to escape before

putting hands or face over the steamer.

Programming - Timer Models

CYC (Total Cycle Time) refers to the total amount of

steaming time set for the product.

SHO (Shot Interval Time) is the time set between

shots of steam during a complete cycle.

H2O Setting (Steam Shot Time) is used to adjust the

water volume used during each pump/solenoid opera-

tion.

The amount of steam produced by your Deluxe Food

Warmer (steamer) depends on the amount of water

sprayed onto the steam generator.

Flooding of the generator may occur if the H2O setting

is set too high. To prevent this from occurring, the Shot

Interval Time (SHO) may be increased to allow more

time for generator heat recovery. Adjustments should

be made to both values to determine the optimum set-

tings for your cooking needs.

To program the control, refer to Figure 7 and use the

following procedure in sequence:

1. Turn the Rocker Switch (power On/Off) to ON.

Cycle Time in minutes and seconds (Item A,

Figure 7).

2. Press and release the Program button to change

the control from OPERATION to PROGRAM

mode.

3. To change the Total Cycle Time in minutes, use

the UP or DOWN arrow buttons to change the

time (Item B, Figure 7).

4. Press and release the Program button again and

use the UP or DOWN arrow buttons to change the

Total Cycle Time in seconds (Item C, Figure 7).

5. To change the SHO factory settings, make sure

the control is in PROGRAM model, then press

and hold the two arrow buttons simultaneously for

1-2 seconds and then release. SHO will be dis-

played (Item D, Figure 7).

Steaming Tips

• Pre-cooked pasta is easily reconstituted and gives

you a hot product without the wetness of the normal

“dip” method.

• Experiment with your products and different

steaming times - a little more or less steam could

enhance the appearance/flavor.

• If you serve melted cheese on sandwiches, steam

is the perfect way to melt cheese.

• A steamed bun (which takes about 10-15 seconds)

says “Hot Sandwich” to your customer.

• Vegetables, rice, and bread products can be recon-

stituted by steaming before serving, which reduces

waste.

• Dinner rolls, muffins, even tortillas can be heated

completely and held without drying out the product.

• Use a low plate or pan when steaming to allow full

steam penetration and shorter cooking times.

• Use the “1 in 20 rule: Push the operate switch for

one second every twenty seconds. This will ensure

that the product gets fully heated without using

excess water or energy.

• Condensation inside the steamer is normal, but

excess moisture indicates too much water is being

used. Use the “1 in 20” rule above and check/

adjust the programming if needed. See the pro-

gramming section of this manual.

• Heat meat and bread products apart from each

other, then combine in a sandwich. This keeps the

meat juices from soaking the bread.

• Clean the top cover gasket as often as possible or

at least once a day with a soft, clean cloth.

• Finish off a special meal with a steamed hand

towel.

Hi-Limit Reset Button

A hi-limit thermostat will turn off electrical power to the

heater if the unit overheats. To reset this thermostat,

allow sufficient time (about 45 minutes) for the unit to

cool down, remove the cap located on the rear of the

unit (Figure 8) and then fully depress the reset button .

If the unit requires continuous resetting, contact your

Roundup authorized service agency.

MAINTENANCE

WARNING

Turn the unit off, disconnect the power source

and allow the unit to cool down before performing

any service or maintenance on the unit.

NOTE: Frequency of cleaning is determined by

water conditions, usage and water filter systems.

CAUTION

Do not use a sanitizing solution or abrasive mate-

rials. The use of these may cause damage to the

stainless steel finish.

CAUTION

If a chemical cleaner is used, be sure it is safe to

use on cast aluminum. Observe all precautions

and warnings on product label.

WARNING

Be sure to follow all of the precautions, proce-

dures, and safety steps listed in the Important

Safety Information section of this manual.

NOTE: Frequency of cleaning is determined by

water conditions, usage and water filter systems.

Daily Maintenance

1. Turn the Rocker Switch (power On/Off) to OFF,

unplug the power cord, and allow the unit to cool

down before proceeding.

2. Check the Water Pressure Regulator gauge

(DFW/DFWT/DFWF-200/250 units only) and verify

that it reads 20-25 PSI (1.4 - 1.7 kg/cm2 or 138-

172 kPa). If not, adjust the water pressure as

described in the Installation section of this manu-

al. Check the rear water Quick Disconnect Fitting

and Hose Clamp for leakage. Tighten clamps or

replace parts if needed.

3. Remove the Trivet and Pan (Figure 10).

4. Wash items in hot, soapy water and then rinse

and WIPE DRY.

5. Wipe down the Top Cover, Gasket, and the entire

exterior of the unit (Figure 10) with a clean, hot,

damp cloth (not dripping wet ) and wipe dry.

6. Re-install Diffuser, Pan and Trivet.

NOTE: Allow Top Cover to remain open overnight.

Monthly Maintenance

The Deluxe Food Warmer utilizes an open steam gen-

erator. Water sprayed onto the generator surface flash-

es into steam immediately, but the minerals in the water

do not steam. They stay on the generator surface. A

small amount of calcium/mineral deposits are need-

ed for proper operation, but a build-up of excessive

calcium/mineral deposits causes poor steaming efficien-

cy, excessive moisture (wet steam), and will eventually

severely retard the steaming action completely.

CAUTION

If a chemical cleaner is used, be sure it is safe to

use on cast aluminum. Observe all precautions

and warnings on the product label.

2. Using a sponge or a dry towel, remove the

delimer solution from the generator surface and

then rinse the surface with clean water.

NOTE: To ensure proper steaming characteristics,

some calcium/mineral deposits must be present on

the Generator surface. If, during cleaning, the sur-

face does become free of calcium/mineral deposits,

add plain tap water to the surface and allow it to

boil off. If necessary, repeat this process to formu-

late a thin coating of calcium/mineral deposits.

NOTE: In soft water areas. it may be necessary to

add a small amount of lime to the Generator sur-

face to “Season” it. This will ensure proper steam-

ing characteristics by producing a thin coating of

calcium/mineral deposits on the Generator surface.

Seasoning mixture consists of 3/4 ounces (25 ml/

25 cc) baking soda, 3/4 ounces (25 ml/25 cc) lime

mixed with 1 quart (950 ml/950 cc) of water. Stir

mixture and pour 1/4” deep onto the hot Generator

surface. After mixture is converted to steam, the

remaining loose powder can be removed.

3. Plug the power cord into the appropriate outlet.

4. Turn the Rocker Switch (power On/Off) to ON.

Allow the unit to warm up for approximately 30

minutes.

5. Push and release the Operate button several

times to operate the steamer. This purges any

remaining delimer residue from the Generator sur-

face.

6. Turn the unit off, reinstall all parts and accesso-

ries, and return the unit to service.

Cleaning the Spray Tube and Steam

Generator

1. Turn the unit off and unplug the power cord.

Allow the unit to cool down before proceeding.

2. Perform the Daily Cleaning, but DO NOT reas-

semble the unit.

3. Remove the Spray Tube (Figure 9) by lifting the

loose end and pulling it out of the generator hole.

4. Slide the metal cover off of the Spray Tube, take

a paper clip and poke out all of the tube’s holes.

Next, gently fix the tube under running water to

wash the deposits out of the loose end. Reattach

the cover onto the tube.

5. Use a scraper or spatula to scrape and remove

the excessive calcium/mineral buildup from the

Generator surface (Figure 10). Remove any

loose buildup and thoroughly wipe the Generator

with a damp cloth and reassemble the unit.

NOTE: If deposits are still excessive and/or difficult

to remove, refer to Steps 1 through 6 below

Replace the Filter if the screen is torn or dam-

aged.

5. Reinstall the filter stem into the bottom hole of the

tank (Figure 11).

6. Fill the Water Tank and test the unit.

Checking and Cleaning the Water Strainer

(Monthly) DFW/DFWT/DFWF-200/250 Only

The Water Strainer protects your equipment from any

foreign debris in the water line that could damage the

unit’s solenoid (causing the unit to leak/flood)

To ensure proper and consistent steaming results, visu-

ally check the Water Pressure Regulator Gauge (figure

12) and Strainer Cup regularly. If the pressure on the

Gauge has dropped, visually check the clear, plastic

Strainer Cup and clean out the accumulated debris as

follows:

1. Shut off the water supply valve to the unit,

unscrew the clear, plastic Strainer Cup, and care-

fully remove the mesh Strainer Screen.

2. At the sink, gently flush all of the accumulated

debris from the Strainer Cup and mesh Strainer

Screen. Be especially careful not to damage the

mesh Strainer Screen.

3. Carefully place the mesh Strainer Screen into its

seat at the bottom of the clear, plastic Strainer

Cup and confirm that the orange O-ring is proper-

ly seated in its place before screwing the Strainer

Cup and top back together.

4. Purge the air out of the Strainer and tubing by

disconnecting the male quick disconnect insert

from the equipment and, over a bucket, push the

“white” plastic tip in until there is good water flow.

6. Verify that the Water Pressure Regulator is set to

20-25 PSI (1.4-1.7 kg/cm2 or 138-172 kPa).

TOP COVER ADJUSTMENT

It is normal for a small amount of steam to escape

around the front and sides of the Top Cover. However,

excessive steam may indicate the Top Cover Gasket is

worn and/or the cover is out of adjustment or damaged.

1. With the Top Cover closed, loosen the four (4)

rear hinge bracket screws (Figure 12) one turn

only.

2. Push down on the top cover heavily (Figure

Technical Theory of Operation (Timer

Models Only)

When the Rocker Switch (power On/Off) is on, line volt-

age flows to the primary side of the step down trans-

former. The transformer’s secondary side supplies 12

and 24 VAC to the Control Board.

Once powered, and provided that the generator temper-

ature is below 380° F (193° C), the Control Board calls

for heat by supplying 10-15 VDC to the solid state relay

terminals 3 (+) 4 (-). Once powered, the relay closes

terminals 1 and 2, which allows line voltage to flow to

the generator

As the generator begins to heat up, a type K thermo-

couple monitors the internal generator temperature. As

the heat continues to increase, so does the thermocou-

ple’s DC millivolts. Once the generator’s temperature

rises to 380 - 420° F (193 - 215° C), the thermocouple

is generating approximately 7.5 - 9.0 DC millivolts.

The Control Board receives these millivolts and pro-

ceeds to remove the 10 - 15 VDC to the Solid State

Relay since the heating circuit is satisfied. The relay

terminals 1 and 2 open, and the generator stops heat-

ing.

When the Operate or the Start/Stop button is pressed,

the Control Board is signaled to supply 24 VAC to the

solenoid valve (used in the DFW/DFWT/DFWF-250) or

the water pump (used in the DFW/DFWT-150) for a split

second.

The solenoid valve opens, or the water pump runs, and

allows a shot of water (approximately 25 ml or 3/4 oz.)

to flow through the spray tube and onto the generator

surface for steaming. The steam rises through the per-

forated pan and steams the product.

NOTE: If the display is in a “Timed Cycle” (Counting

Down), the Control Board will continue to activate

the solenoid valve or water pump for repeated

shots of water, once every 20 seconds, and for

the duration of the cycle time displayed. See the

Programming section of this manual for more infor-

mation.

The Control Board’s parameters can be custom pro-

gramed for the overall cycle steam time (CYC), as well

as the interval time in seconds (SHO) when each shot

of water occurs, and also the water volume (H2O) used

per each shot of water. This Control Board also incor-

porates four diagnostic LEDs (See the Operation sec-

tion of this manual).

An audio signal will sound for three seconds at the end

of a Timed Cycle. If the heating circuit continues to call

for heat and the Generator overheats, a manual reset-

table Hi-Limit Thermostat will trip and open the genera-

tor circuit.

Technical Theory of Operation (Non-Timer

Models Only)

When the power switch is on, line voltage flows to the

primary side of the step down transformer. The trans-

former’s secondary side supplies 24 VAC to the Control

Board’s terminals T1 and T2.

Once powered, and provided that the generator tem-

perature is below 380 F (193 C), the Control Board

calls for heat by supplying 15-20 VDC to the Solid State

relay terminal 3 (+) 4 (-). Once powered, the relay

closes terminals 1 and 2, which allows line voltage to

flow to the generator.

As the generator begins to heat up, a 100 K Ohm

thermistor monitors the internal generator temperature.

As the heat continues to increase, the thermistor’s

ohms begin to decrease. Once the generator’s tem-

perature rises to 380-420 F (193-215 C), the thermistor

is generating approximately 800-500 ohms. .

The Control Board reads these ohms and proceeds to

remove the 15-20 VDC to the Solid State Relay since

the heating circuit is satisfied. The Relay terminals 1

and 2 open, and the Generator stops heating.

When the Operate button is pressed for one second, it

supplies 24 VAC to the solenoid valve used in the DFW/

DFWT-200 or the Water Pump used in the DFW/DFWT-

100 for a split second.

The solenoid valve opens, or the Water Pump runs, and

allows a shot of water (approximately 25 ml or 3/4 oz.)

to flow through the Spray Tube and onto the Generator

surface for steaming. The steam rises through the per-

forated pan and steams the product.

This Control Board incorporates 2 diagnostic LEDs (see

the Operation section of this manual). If the Heating

Circuit continues to call for heat and the Generator

overheats, a manual resettable Hi-Limit Thermostat will

trip and open the Generator circuit.
