G.
Lifting holes have been provided at the corners or along sides for attaching lifting slings.
Spreader bars must be used when lifting so that lifting forces are applied vertically. If
more than 4 lifting holes are provided on the condenser, more than four lifting points
should be used.
2.3 REFRIGERANT PIPING
A.
All refrigerant piping must be installed by a qualified refrigerant mechanic.
B.
The importance of correct refrigerant pipe sizing and layout cannot be over-emphasized.
Failure to observe proper refrigerant piping practices can result in equipment failure
which may not be covered under warranty.
C.
All air-cooled condensers are supplied complete with headers and refrigerant connections
sized for connecting the standard refrigeration tubing.
D.
These connections may bot be the same as the actual line sized required for the field
installation. Refer to a recognized source (ASHRAE charts, manufacturer’s engineering
manuals etc) for line sizing.
2.4 DISCHARGE LINES
A.
The proper design of discharge lines minimizes refrigerant pressure drop since high
pressure losses increase the required compressor horsepower per ton of refrigeration.
B.
A discharge check-valve at the bottom of a vertical riser will prevent oil (and liquid
refrigerant) from draining back to the compressor during the off-cycle. A check valve may
be factory or field supplied.
C.
A reverse trap should be installed at the top of all vertical risers. The top of the reverse
trap should be the highest point in the discharge line and should have an access valve
installed to allow the reclamation of non-condensible gas from the system.
