Installation
WARNING
The equipment described in this manual is designed to operate with
LP-gas, a flammable fuel under pressure. The nature of the
application involves inherent hazards that could result in injury.
ONLY a trained and fully qualified person should service this
equipment.
The
BLENDAIRE
mixer should be installed in an area suitable for its use. The
mixer must be placed on a level pad with no pits or depressions so no gas will
accumulate. Care must be taken in the entire operating area so that LPG is
never near or below its dewpoint in the system at any time. Heat tracing may be
required depending upon location, LPG content and pressure. Mount each
BLENDAIRE
unit on a concrete pad strong enough to support its weight (See
equipment drawing).
Every unit is equipped with Auto-Ratio-Adjust, however, a gas quality-measuring
device suitable for the specific operating conditions is required for activation.
The total response time, including sample lag time, should be kept to a minimum.
This can be done by keeping the sample mixed gas line from the pipe to the
instrument as short as possible.
CAUTION
Always consult with local codes and authorities prior to installing
equipment.
The following equipment must be installed for proper operation of the blending
systems:
1. Air supply
2. Vapor supply
3. Mixed gas outlet
4. Instrument air supply
5. Process controls
