1. Maintain valve end protection.

2. Store valves indoors and maintain at higher than ambient dew-point temperature. If outdoor storage is necessary, store valves off the ground in watertight enclosures.

C. Inspect the shipping container before unpacking to look for damage that could have occurred during transport, and report it to the transportation company immediately. After visual inspection, remove the valve from the shipping container. Make sure the faces are free of any scratches and that there is not any obvious damage to the actuator assembly or valve body.

D. Make sure to note the valve's model number during the unpacking process. The model number will need to be provided when purchasing replacement parts.

Install valve drains with hose end adapter and cap on chain for each valve that must be installed with stem below horizontal plane. Ensure installation provides full stem movement.

K. Insulation: Where insulation is indicated, install extended stem valves, arranged in proper manner to receive insulation.

L. Seats: Renewable seats, except where otherwise indicated.

M. When soldering, use paste flux that are approved by the manufacturer for use with lead free alloys.

N. If valve applications are not indicated on Drawings, use the following:

1. Shutoff Service: Ball valves.
