NOTICE
When removing the cooling module from the package for remote operation, do
not use the flexible coupling (when supplied) between the air/oil separator
housing and the minimum pressure/check valve. The discharge piping from the
air/oil separator housing should be piped into the minimum pressure/check
valve, then into piping to the cooler, with a flexible connection between the
minimum pressure/check valve and aftercooler to keep the weight of the piping
off of the cooler.
HEAT EXCHANGER (OIL) PIPING
- All remote elevated cooler applications must be sent through
engineering for approval and pipe size recommendations. The control manifold and all non-cooler related
control tubing will be mounted on the package at the factory.
NOTICE
Remote mounted elevated coolers have a maximum pipe length of 30 feet (9 M)
(each way) and a maximum height of 20 feet (6 M) with a minimum of fittings. A
remote elevated cooler form, J214, is required to be filled out. Customer Service
will review all forms while in the quote stage. Customer Service will include the
filled out J214 form on any special orders sent to Engineering.
NOTICE
When removing the cooling module from the package for remote operation, the
oil stop valve and the check valve that are shipped loose should be mounted as
close to the compressor package as possible. Flexible connections should be
used to keep the weight of the piping off of the cooler.
Contact the factory for the appropriate remote cooler mount kit which will include the oil stop valve, check
valve and flanges for the application. The components must be installed on all remote elevated coolers per
Figure 5-4
, page 70, and the following instructions:
1.
Mount the check valve as shown.
2.
Mount the drain valves in the lowest section of the pipe on each side of the cooler connections.
3.
Mount the oil stop valve in the line post oil cooler.
Modifications to the control lines will be made at the factory. When the machine blows down, it will activate
the pneumatic oil stop valve and it will shut off the air and vent the line between the pneumatic control valve
and the oil stop valve to atmosphere. This will shut the oil stop valve and prevent excessive oil from running
into the reservoir.
Failure to install these parts or installations with pipe lengths and/or vertical runs outside the
recommended limits, could result in high oil carryover and cause the machine to shut down on high
discharge temperature.
