LCN 4631-689 – Frequently Asked Questions

1) What is the LCN 4631 pull side surface mounted electrohydraulic auto equalizer power operator used for?
The LCN 4631 is designed for pull side surface mounting on heavy commercial doors. It provides automated opening and closing with electrohydraulic power and auto equalizer functionality for smooth operation.
2) What door types and weights is this operator compatible with?
This operator is designed for heavy commercial doors typically weighing up to 400 pounds. Compatible with aluminum storefront doors, glass entrance doors, and heavy steel doors. Verify specific door weight and dimensions with manufacturer specifications.
3) How do I determine the correct handing for installation?
Handing is determined from the outside of the building looking at the door. If hinges are on the right and door opens toward you, it's right hand reverse. If hinges are on left and opens toward you, it's left hand reverse. Specify handing when ordering.
4) What finish options are available for the LCN 4631?
Standard finish is powder coat which provides durable corrosion resistance. Additional finish options may include anodized aluminum finishes. The powder coat finish is suitable for most commercial applications and weather conditions.
5) What power requirements does this electrohydraulic operator need?
The electrohydraulic system typically requires 110V AC power supply. Verify exact electrical requirements with installation documentation. A dedicated circuit may be required depending on local electrical codes and building requirements.
6) Does this operator meet ADA compliance requirements?
When properly installed and adjusted, this operator can help meet ADA accessibility requirements for automatic door operation. Verify opening force, timing, and safety features comply with local ADA interpretations and building codes.
7) What additional parts or accessories might be needed for installation?
Installation may require door reinforcement, mounting brackets, electrical controls, safety sensors, and push/pull plates. A complete access control system may include card readers or push button activators. Consult installation template for specific hardware requirements.
8) What are the basic installation requirements for surface mounting?
Surface mounting requires adequate door frame strength and proper clearances. The operator mounts to the door frame header area. Ensure frame can support the operator weight and operational forces. Follow manufacturer's installation template for exact positioning and fastener requirements.
9) How is the auto equalizer feature adjusted and maintained?
The auto equalizer adjusts opening and closing forces automatically. Regular maintenance includes checking hydraulic fluid levels, cleaning operator housing, and testing safety features. Adjustment should be performed by qualified technicians following manufacturer procedures.
10) Are there similar LCN models that could substitute for the 4631?
Related LCN power operators include other 4600 series models with different mounting configurations or power ratings. The specific model depends on door weight, mounting requirements, and power needs. Consult with LCN specifications to identify suitable alternatives.
11) What environmental conditions can this operator handle?
The powder coat finish provides weather resistance for standard commercial applications. Operating temperature ranges and humidity limits are specified by manufacturer. For extreme weather conditions or coastal environments, verify suitability and consider additional protective measures.
12) What are the key measurements needed before ordering?
Measure door width, height, weight, and frame dimensions. Note available clearance above door for operator mounting. Confirm electrical supply location and door swing direction. Verify frame construction can support operator mounting loads per installation requirements.
