Fluid Power Actuator Honeywell – V4055, V4062 & V9055

FLUID POWER ACTUATOR RECALL REMINDER

AUTHORIZED BCS 7700, 7800 SERIES AND FLAME SAFEGUARD DISTRIBUTOR

In November 1998, Honeywell announced the recall of V4055, V4062 and V9055 Fluid Power Actuators with manufacturing date codes of 9744 through 9841. We determined that these actuators may have a manufacturing defect which could result in delayed closure of gas valves, possibly creating the risk of a combustion side explosion.

Thankfully, by proactive communication of the potential danger and the publishing and implementation of a safety check-out procedure for start-up, serious damage and injury have been avoided. The check-out procedure allowed many users to continue to operate safely until replacement units were available. However, all users must be aware that it is still necessary to change-out the affected recalled actuators to avoid potential unsafe conditions in the future.

Action Required

We would like to reiterate that it is still a priority to identify the recalled actuators and have them changed out as soon as possible. Do not continue to operate any longer than necessary, or re-start equipment that has been shutdown without following our attached check-out addendum. Replacement units are available and change-out can be accomplished quickly. Always use the installation and instruction start-up procedure when restarting a unit after actuator replacement. If you have any questions, call the hotline at 1-877-487-7532.

Thank you for your continued support and cooperation. If you have any questions, please contact Steve Sundberg (612/954-4414), Lisa Holmberg (612/954-6606) or me (612/954-5403).

FLUID POWER ACTUATOR RECALL UPDATE

September 17, 1999

AUTHORIZED BCS 7700, 7800 SERIES AND FLAME SAFEGUARD DISTRIBUTOR

Since the Honeywell Fluid Power Actuator recall was announced on November 10, 1998, we have been producing replacement units at maximum capacity. We are pleased to announce that we have met all outstanding requests for recall replacement units and are current on all back ordered actuators. We are replenishing our inventory and are able to meet all of your production requirements.

When we implemented the recall, replacement units were shipped to you at no charge. Even though we have shipped out over 100% of the replacement units, the rate of return for the replaced actuators has slowed considerably. In the coming weeks, we will be asking for your continued cooperation in performing a final reconciliation of shipments and returns. You will receive a worksheet containing information on the number of units originally purchased during the recall period, the number of replacement units shipped to you, the number of units returned to Honeywell and the difference, less any units that have already been reconciled. With your assistance, we would like to determine the status of all the outstanding units and enlist your assistance in closing the loop with your customers.

Once we complete the final reconciliation, we will close this phase of the Fluid Power Actuator Recall. By it’s very nature, recalls do not end until all units are found, replaced and returned. Therefore, if there is a need for a replacement actuator in the future, it will be provided.

Thank you for your assistance and support during the recall and in this final reconciliation process. We greatly appreciate your efforts and those of your customers in the administration of this recall. If you have any questions, please contact Steve Sundberg at 612/954-4414, Lisa Holmberg at 612/954-6606 or myself at 612/954-5403.

HONEYWELL FLUID POWER ACTUATOR RECALL ADDENDUM

September 17, 1999

Subject: Honeywell Fluid Power Actuator Recall (V4055/V4062/V9055)

The following clarifying information regarding continued use of the fluid power actuator pending replacement may be incorporated in communications with your customers.

Sincerely,
Dennis L. Mool
General Manager
Burner Boiler Control
Honeywell Inc.

We have been notified by Honeywell of a Recall of it’s V4055, V4062 and V9055 Fluid Power Actuators (FPA) with the manufacturing date codes of 9744 through 9841. These FPA may have a defect which can cause a safety issue. The malfunction is characterized by temporary “sticking” of the hydraulic fluid dump valve. This malfunction can result in delayed closure of the gas valve after electrical power is interrupted to the FPA. The possibility of the gas flow not shutting off upon command creates a safety issue.

Honeywell has determined that the frequency of FPA use substantially impacts the potential hazard. If the FPA is used on a daily basis, meaning it cycles at least once every 24 hours, the FPA appears to be reasonably safe and continued use pending replacement is appropriate. Honeywell has had no reports of failures with this usage pattern.

If, however, the FPA is used infrequently, meaning it is cycled less than once per 24 hour period, the problem may be present. Therefore, if your usage of the FPA is infrequent then before employing the FPA do the following test performed by a qualified service technician per Honeywell installation instructions.
