charge (for operating charge, add listed HS charge to field
piping and remote condenser charges).

Location of mounting holes:
The sensing bulb of the chilled water temperature
controller is in a well in the return water connection. The
temperature controller is factory set to control from return
chilled water.
Plan piping for minimum number of changes in elevation.
Install manual or automatic vent valve at high points in line.
Maintain system pressure by using a pressure tank or
combination relief and reducing valve.
See Carrier System Design Manual, Part 3, Piping, for
chilled water piping details.
Install thermometers in entering and leaving lines. Provide
drain connections at all low points to permit complete
drainage of system. Connect shutoff valve to drain line before
operating unit. Install shutoff valve near entering and leaving
water connections. Use flexible connections on condenser and
cooler piping to reduce vibration transmission.
Insulate piping after leak testing to prevent heat transfer and
sweating. Cover insulation with moisture seal.
REFRIGERANT CHARGE
Refrigeration installations must be inspected and
maintained regularly and rigorously by specialists. Their
activities must be overseen and checked by properly trained
people. To minimize discharge to the atmosphere, refrigerants
and Lubricating oil must be transferred using methods, which
reduce leaks and losses to a minimum.
Leaks must be repaired immediately
All units are equipped with two special connections on
the suction and liquid line, which permit the connection
of quick-connect recovery valves without loss of
refrigerant.
If the residual pressure is too low to make the transfer
alone, a purpose-built refrigerant recovery unit must be
used.
Compressor lubricating oil contains refrigerant. Any oil
drained from a system during maintenance must therefore
be handled and stored accordingly.
Refrigerant under pressure must never be discharged to
the atmosphere
