Equipment Description

The Groen GG3-E Self-Contained Atmospheric Steamer consists of a cooking chamber, a steam generator
with heating element, and a control compartment housing the electrical components and plumbing, all
encased in a stainless steel cabinet.

Two outstanding features on the GG3 are the automatic drain and stand-by power. As long as the main
power switch is on and the boiler is warmed up, stand-by power (about 2% of full power) is fed to the heating
element to keep the boiler water at incipient boil and ready for immediate full-steam generation. The
automatic drain feature operates after the main power switch has been turned off. The unit will drain
completely to flush sediment out of the steam generator.

The drain is located in the lower rear center of the chamber and is connected to the drain pipe. The pipe
includes a spray condenser, which suppresses any steam escaping the chamber. A small tray below the door
is provided to catch any condensate drip.

Model GG3-E will accept the following combinations of full-size perforated or solid cafeteria pans:

Two pans, 4" deep
Three pans, 2 1/2" deep
Six pans, 1"deep

The steam generator compartment is located behind the cooking chamber and is accessible through the right
side panel. The control assembly can be accessed from the front panel and can be lifted out. Power should
always be turned off before removing any panel.

The steam generator functions in a simple manner. A normally-closed solenoid valve opens and allows water
to enter until the proper level is sensed. The solenoid valve then closes, and the water is quickly converted to
steam by the heating element. This function is repeated when necessary, as long as the timer is in the timing
position.

The GG3-E Steamer is designed to be virtually maintenanace-free; however, normal wear of certain parts
may require that they be replaced after prolonged use. This steamer has been adjusted at the factory, so no

field adjustment should be necessary. If need for adjustment does arise, only Groen personnel or Groen's
authorized representatives should handle the work.

Water Conditioning

It is absolutely essential to supply the Groen steamer with water that will not form scale at an unacceptable
rate. The steam generator was engineered to minimize scale formation, but scale formation depends on the
hardness of the water and the hours of operation. In a few areas of the United States, the water supply is
sufficiently free of minerals to avoid scale formation. However, most water supplies carry heavy loads of
minerals, which will form scale on the generator, reduce its steam output, and possibly cause premature
failure of components.

Your local water utility can provide a statement on the scale forming qualities of the water supply. Water
supplied to the generator should contain not more than 30 parts per million total dissolved solids (TDS) and

should have a ph of 7.0 or higher. Please follow these simple precautions:

1. Do not rely on "water treaters" commonly sold as scale preventers and scale removers. They do not
work. The only proven way to prevent scale build-up is to feed in water practically free of scale-forming

minerals.

2. If your water supply carries scale forming minerals, as most water supplies do, run the water through a
properly maintained softener. Exchangeable softener cartridges or a regeneratable softener can be used.

In either case, establish a regular program of exchanging the cartridges or regenerating the softener.
Installing a water meter on the inlet line between the softener and the generator will give an accurate
check of water consumption and a way of determining when to change the cartridge or regenerate the
softener.

By using a softener and operating within the softener's capacity to exchange minerals, the user will obtain
a longer generator life, high steam capacity, and minimum maintenance requirements.

3. If you notice a slowing of steam production, pull the heating element out of the steam generator and
check it for scale.

WARNING: DISCONNECT ELECTRIC POWER BEFORE YOU REMOVE THE CASING FROM THE
STEAMER.

Heavy scale will reduce the element's ability to boil water and can elevate element temperature to the point
where the element will fail prematurely.

Some scale is soft enough to be scraped off, but scraping must be done carefully to avoid damaging the
element bars or safety thermostat. Cleaning with sulfamic acid, inhibited muriatic acid, or another
commercially available deliming agent can be dangerous and should be done only by an expert familiar
with the hazards. Vinegar will dissolve most scales, but the treatment requires a long time and frequent

changes of the vinegar solution.

TO AVOID ALL SCALE PROBLEMS, USE AND PROPERLY MAINTAIN A SOFTENER.

Installation

Mounting

After the inspection, keep the unit crated until it is installed.
When installation is to begin, remove the crate or box from the skid. Remove the four mounting bolts that

fasten the skid to weld nuts in the base of the steamer. Keep the bolts, as they are required for installation.
Hoist the unit to its mounting location with a cloth-wrapped sling (to protect the polished surfaces).

Level the table top or counter on which the GG3 Steamer will be mounted. Unless the optional legs will be
used, drill four holes (of 1/2 inch diameter) that will align with the anchor nuts welded into the steamer base. If
service connections will be made through the mounting surface, also drill holes for those supplies at this time.
Once the steamer has been removed from its shipping container and placed on the leveled mounting surface,
secure the unit with the skid mounting bolts saved during unpacking. After the steamer has been bolted in
place, seal the joint between steamer base and mounting surface with a suitable caulking compound like RTV
sealant.

If the steamer was purchased with optional legs, screw the legs into the anchor nuts on the base.

WARNING: THE STEAMER MUST BE INSTALLED BY PERSONNEL QUALIFIED TO WORK WITH

ELECTRICITY AND PLUMBING. IMPROPER INSTALLATION CAN CAUSE INJURY TO
PERSONNEL AND/OR DAMAGE TO THE EQUIPMENT. INSTALL THE UNIT IN
ACCORDANCE WITH ALL APPLICABLE CODES.

CAUTION: To avoid damage to the steamer and possible voiding of warranties, follow the directions in

the "Water Conditioning"section before you connect the water supply.

Water Connections

Connect the cold water line (1/4 inch NPT) to the factory-supplied flexible hose, then connect the hose to the
steamer. A check valve must be installed, and some codes require a second check valve. (See the piping

diagrams.) To maintain the required pressure and flow rate accurately, install a strainer and a pressure
reducing valve. The required flow rate at 30 PSIG is 0.28 to 0.33 GPM tor the 5 KW steamer or 0.31 to 0.36
GPM for the 7.5 KW steamer.

Drain Connections

The steamer is equipped with a 1 1/4" ID x 48" long drain hose. Direct this hose over an open floor drain, or
connect it to a 1" (or larger) IPS pipe header and extend the header to a nearby floor drain. GROEN
recommends that the header have no more than 2 elbows and be no longer than 6 ft. If the header will have
more than 2 elbows or be longer than 6 ft, use 1 1/2" IPS pipe.

Remember: This is a gravity drain that must be able to vent

freely to the atmosphere.

At the floor drain there must be an "air gap" of at least 2",
unless local codes specify a different gap. The drain must be
set lower than the steamer base.

CAUTION: The steamer drain discharges steam and hot condensate. To direct the flow of

the condensate to the floor drain, comply with these instructions and recom­mendations.

Electrical Connections

Any mechanical or electrical change must be approved by the Groen Division Food Service Engineering
Department. The required electrical supply is protected by fuses in the steamer and is specified on an
information plate at the rear of the unit. Power must be connected to a terminal block inside the junction box
in the rear of the steamer. Stacked units require separate electrical connections for each unit. Local codes
and/or The National Electrical Code should be observed in accordance with ANSI/NFPA-70 latest edition.

GG3-E Steamers are shipped with 3 phase wiring. For field conversion to single phase operation, consult the
label on the rear of the unit or the diagram included in this manual.

Initial Start-Up Of The GG3

Now that the steamer has been installed, the initial testing to ensure that the unit is operating correctly
should performed.

1. Remove all literature and packing from the interior and the exterior of the unit.

2. Be sure water line to the steamer is open.

3. Turn on electrical service to the unit.

4. Verify that the strainer for the chamber drain and all of the pan supports are in place.

5. Push the ON/OFF power switch to the ON position. Switch will illuminate, indicating that
power is on.

6. Set the timer for approximately 5 minutes. Steam should be visible after about 3 minutes
of operation. Check condensate drain to ensure proper drainage.

7. To turn off the alarm at the end of the timing cycle, set the timer to zero.

To completely shut down the unit push the ON/OFF power switch to the OFF position. (The light will go
out and the steamer will automatically start to drain.)

If the steamer has functioned as described above the unit is ready for use. If the steamer does not function
as intended, call your Groen Authorized Agent.

11

Operation

The operator controls are located on the front right side of the unit. The power switch is used to ready the
steamer for use, and to shut the unit off. For frequent use, the unit may be left on. The 60-minute timer is the
only control which has to be operated. Turn the knob to the desired time. When this time has elapsed, an
alarm will sound continuously until the knob is turned from the alarm mode to the OFF position. If further
steaming is required, turn the timer knob to the additional time required. The ready lamp will light at finish of
elapsed time.

A. Start-up Procedure

Push power switch to the ON position. Set timer to 5 minutes to fill steam generator and warm up the
unit.

B. Cooking

1. Load food into pan so that there is a uniform layer. Slide pan onto supports. Use middle pan position
when only using one pan.

2. Close door.

3. Set timer at the desired cooking time. The optimum time can only be determined by test due

to influence of initial product temperature, amount of product, water or ice present, thickness
of layer, etc. (See recommended Cook Time Chart provided for approximate settings.)

4. Alarm will sound, ready lamp will light, and steam will cut off when set time has elapsed.

5. To stop alarm, turn timer knob from alarm mode to OFF position.

WARNING: STEAM CAN CAUSE BURNS. USE CARE WHEN OPENING DOOR TO CHECK OR
REMOVE FOOD.

For best results in steam cooking, be sure that operator understands how to use GG3 Steamer, and that
proper maintenance and daily cleaning are performed by a qualified person.

C. Cleaning
At the end of the day, both the interior and exterior of the steamer should be cleaned. See the Maintenance

& Cleaning section of this manual for instructions.

12

Sequence Of Operation

The following outline is provided as a means for better understanding the actual functioning of the steamer.
This "action-reaction" type of outline should guide the user through operational steps.

When the power switch is turned on and the timer is set to "O", the ready lamp will light, the dump valve will
close, and the water fill valve will open, filling the steam generator until the probe senses the proper water
level. When the timer is set at a cooking time, full power will flow to the heating element and the condenser
water will start to flow. If the water level does not reach the level-sensor probe within about 5 seconds, the
power to the heating element and the condenser water will automatically be turned off until water reaches the
probe.

During the cooking time, the probe will sense when water is needed and will open and close accordingly.
When the cooking time has elapsed, the alarm will sound and can be silenced by turning the timer back to
"OFF". Also, at the end of the cooking period, the current to the element is turned off, the ready lamp will
come on, and the condenser water will shut off. If the timer is not reset for a cooking cycle, after
approximately 4 minutes, the stand-by power (2% of full power) will be applied to the heating element so that
the water in the boiler will remain at incipient boil and the unit will be ready for immediate cooking.

If the water feed fails, check for blockage (see Page 13) When the water level has fallen below the probe for
more than about 5 seconds, all power will be removed from the heating element and will remain off until the
water level is restored. At restoration, if the timer is set at zero, stand-by power will come on in about 4
minutes and, because of its low imput (2%), it will slowly warm up the new water in the boiler. To offset this
delay, after the water supply has been restored, set the timer for a 5-minute warm-up.

If the heating element overheats due to control failure, or low water, a safety thermostat in the element will
cut off all power and automatically reset only after the element has cooled to a safe temperature. At that time,
power to the element will resume. If the water has not been restored, the element will quickly overheat again,
and the thermostat will again cut off the power.

When the main power switch is turned off, all power is removed from the heating element and the control
circuit downstream from the switch. Also, the dump valve will open and allow the steam generator to drain. If
condenser water is flowing at this time, it will be turned off.

Maintenance & Cleaning

The GG3 Steamer is designed for minimum maintenance, but certain parts may need replacement after
prolonged use. Always supply low-mineral water. No user adjustment should be necessary. If a service

need arises, only Groen personnel or authorized Groen representatives should perform the work.

CAUTION: Use of any replacement parts other than those supplied by Groen or their authorized

distributor VOIDS ALL WARRANTIES and can cause bodily injury to the operator and
damage to the equipment. Service performed by other than factory authorized personnel
WILL VOID ALL WARRANTIES.

WARNING: ALWAYS SHUT OFF THE ELECTRIC POWER BEFORE WORK IS DONE ON
INTERNAL COMPONENTS .

13

If the steamer is cooking slowly, check the heating element for scale build-up and clean or replace it as
necessary. Also, check the water supply. If the heating element is in good condition, check the strainer in the
water inlet. The strainer is found in the right lower corner of the control compartment. Remove the nut on the
strainer, pull out the screen, and clean it out.

If the electrical components need to be checked, they can be reached through the removable panel on the
front of the unit.

Fuses for the steamer are located on the rear panel. Should they ever need to be replaced, the fuse knob
can be unscrewed to expose the fuse. The user can then pull out the fuse and replace it.

Door Latch Adjustment
If steam or condensation is noticed leaking from around the door seal, and inspection of the cooking chamber

drain shows no blockage, the door requires adjustment. All gaskets will creep at temperatures like those
found in a steamer. Groen has designed an adjustable latch on the door to compensate for gasket
compression and aging.

To make an adjustment, loosen the two latch nuts and move the latch catch plate toward the handle,
decreasing the space between the chamber and the door gasket on the right side of the steamer. Tighten the
nuts securely.

Daily Cleaning Program
