INSTALLATION, OPERATION AND CARE OF

BAXTER MODEL WM600 & WM600C WATER METER

SAVE THESE INSTRUCTIONS

GENERAL

The WM600 & WM600C Water Meter is a microcomputer-controlled water delivery system that enables
you to accurately control the water requirements for your baking needs. Through the proper control of
water temperature and volume, the water meter will help you gain uniform baking results and maximum
productivity.

Baxter Water Meters are produced with quality workmanship and material. Proper installation, usage and
maintenance of your water meter will result in many years of satisfactory performance.

It is suggested that you thoroughly read this entire manual and carefully follow all of the instructions
provided.

INSTALLATION

The water meter requires separate hot and cold supply lines. Each line should have a manual shutoff valve
(not supplied) at the water meter for servicing and shutdown. Before installing, verify that the electrical
service agrees with the specifi cations on the data plate located on the left panel of the water meter. If the
supply and equipment requirements do not agree, do not proceed with the installation. Contact the Bakery
Systems service department immediately.

UNPACKING

This water meter was inspected before leaving the factory. The transportation company assumes full
responsibility for safe delivery upon acceptance of the shipment. Immediately after unpacking, check for
possible shipping damage. If the water meter is found to be damaged, save the packaging material and
contact the carrier within 15 days of delivery.

LOCATION

Before fi nalizing location, make sure that consideration has been given for water supply, draining, electrical
outlets and service clearances.

WALL MOUNTING

The water meter has a detachable base for wall mounting. It is secured by a machine screw located on
the bottom panel.

1. With the water meter lying fl at, control face up, remove the machine screw and angle holddown.

2. Slide the water meter forward and set aside.

3. Position the base on the wall and level left-to-right using a carpenter’s level.

4. Mark the position and hole location.

5. Mount the base to the wall using the appropriate mounting fasteners.

6. Slide the water meter, with the control panel facing up, downward onto the base. Make sure the
horizontal groove on the back of the water meter is lined up with the top edge of the base.

7. Secure water meter to the base with the

machine screw and angle holddown.

8. Check to make sure the water meter is level.

INSTALLATION CODES AND STANDARDS

The water meter must be installed in accordance with:

In the United States of America:

1. State and local codes.

2. National Electrical Code, ANSI/NFPA-70 (latest edition). Copies may be obtained from The National
Fire Protection Association, Batterymarch Park, Quincy, MA 02269.

In Canada:

1. Local codes.

2. Canadian Electric Code, CSA C22.1 (latest edition). Copies may be obtained from The Canadian
Standard Association, 178 Rexdale Blvd., Etobicoke, Ontario, Canada M9W 1R3. (electric

equipment)

In Europe:

1. Local codes.

ELECTRICAL CONNECTIONS

Electrical and grounding connections must comply with the applicable portions of

the national electrical code and/or other local electrical codes.

Appliances equipped with a fl exible electric supply cord are provided with a
three-prong grounding plug. This plug must be connected into a properly grounded three-prong
receptacle. If the receptacle is not the proper grounding type, contact an electrician. Do not remove
the grounding prong from this plug.

Electrical Option

Electrical data is located on the left panel as you face the water meter. Route the power cord safely out
of the way of other equipment, personnel and moisture.

US Europe Auxiliary Relay Rating

If the equipment is used in a manner not specifi ed by the manufacturer, the protection provided by the
equipment may be impaired.

– 4 –

Units with 120VAC Power Supply

• Replace any UL listed fast-acting 0.5A/250VAC
fuse inside the water meter if fuse is blown.

Units with 230VAC/250VAC Power Supply

• For 230VAC/250VAC operation, replace any
UL listed fast-acting 3A/600V fuse inside the
junction box if fuse is blown.

Input power line and branch circuit protection will be
provided and wired by customer. Refer to Fig. 1 for
240V junction box wiring diagram.

NOTE: It is recommended that a switch or circuit breaker
(marked as the connecting device) is located near the
equipment and within easy reach of the operator.

Water Chiller Option

Fig. 1

If water chiller is pump-driven, connect the chiller to the water meter as described in the steps below.
Connection to the water chiller circuit should be done by a qualifi ed electrician or service technician. The

auxiliary switch is located in the top-mounted junction box.

Disconnect the electrical power to the machine and follow lockout / tagout

procedures.

1. Verify that the water chiller circuit does not exceed the
auxiliary relay rating.

2. Remove the junction box cover screws, cover and
gasket.

3. Connect water chiller and meter per Fig. 2.

4. Install the junction box gasket and cover. Secure with
the previously removed junction box screws.

5. Connect power to the meter. While test is fl owing, verify
that the water chiller pump motor is running in the proper
direction.

WATER SUPPLY

The water meter requires separate hot and cold supply lines. A manual shutoff valve (not supplied) should
be installed on each supply line at the water meter to accommodate servicing and shutdown.

• HOT WATER INLET TEMPERATURE: 140°F (60°C) recommended.

• HOT AND COLD WATER FLOWING PRESSURE: 30 psi (207 kPa) minimum.

• WATER HARDNESS: 4 to 6 grains per gallon (0.7 to 1.0 grains per liter) is recommended.

DRAIN CONNECTIONS (FIG. 3)

The water meter should be located near a sink for the bypass line to drain into while test fl owing or when
water is adjusting to a set temperature.

For water meters equipped with a water chiller and with a water reservoir, a bypass return line should be
connected back to the water chiller reservoir.

WATER METER AND HAND SINK SETUP

NOTE: The hot and cold water supply lines can vary in location.
