Valve Body

1. Clean the lines upstream from the valve. Remove any debris larger than 0.06" (0.015 mm).

2. Alignthevalve’sowindicatorwiththesystem ow.

3. Mount the valve so the actuator is positioned over valve.

CAUTION

Using mineral oil lubricants or other incompatible substances in system ﬂuids may damage EPDM rubber seals in valves. Before using any lubricant or additive in a water or ethylene glycol base, consult the substance manufacturer for compatibility with EPDM (Ethylene Propylene Diene Monomer).

Wiring

NOTE: The installed actuator model is indicated

by the last two digits of the VEB valve model number (e.g., VEB-43xxxxCK has an MEP-4002V actuator) and the last three digits of the older VEP valve model number (e.g., VEP-45xxx745 has an MEP-4002 actuator). For wiring and other

information about tri-state and other actuators no longer sold mounted on these valves, see the respective actuator’s installation guide on the KMC web site.

CAUTION

To prevent condensation from dripping onto the actuator housing, mount the valve with the actuator in the upright position or, at most, at a 45° angle.

4. Seal valves with approved pipe sealant.

5. Using two wrenches, secure the valve to the pipe. Torque should not exceed 75 ft-lb. (102 N

6. Eliminate air from the system to keep the valves

fullofuidduringoperation.

NOTE: If the system experiences large amounts of

debris, steps should be taken to keep the system clean.

Series Data Sheet on the

KMC web site.

For additional instructions on wiring, feedback selector, and actuator/signal range reset (auto-mapping), see the MEP-4000/4800 Series Installation Guide or (fail-safe) MEP-4200/4500/4900 Series Installation

Guide.

Operation

After the mechanical and electrical installations have been completed, cycle the actuator to verify the direction of rotation for normal operation and fail-safe if so equipped.

Maintenance

No routine maintenance is required. Each component is designed for dependable, long-term reliability, and performance. Careful installation will also ensure long-term reliability and performance.

For non-fail-safe wiring, auxiliary switches, feedback/direction selectors, actuator/signal range reset (auto-mapping), and other information, see the MEP-

4000/4800 Series Installation Guide.
