MULTIPLEX REMOTE CONDENSER
PRE-INSTALLATION REQUIREMENTS
1. Installation and maintenance are to be performed
only by qualified refrigeration personnel. These
technicians must have EPA certification (USA),
are familiar with local codes and regulations, and
are experienced with this type of remote
refrigeration equipment.
2. As a condition of the warranty, the check, test and
start-up procedure must be performed by qualified
personnel. Because of possible shipping damage,
check both the condensing unit and refrigeration
unit(s) for refrigerant leaks.
3. If the refrigeration unit is located on a roll out
platform, you must coil up to one round between
the back of the stand and the wall. This allows pull
out of the refrigeration unit for servicing.
4. If the refrigeration unit is located in a stationary
location, you must remove excess refrigeration
tubing as described below.
MULTIPLEX PRE-CHARGED REFRIGERATION
LINES PRE-INSTALLATION REQUIREMENTS
1. Both the discharge and liquid remote condensing
lines must be kept to a minimum distance for
maximum performance. All Multiplex systems are
capacity rated to 100 ft (30.5 m) tubing distance
between the compressor and condenser.
2. Any vertical rise 25 ft (7.62 m) or greater must
have a manufactured or installed trap (bend), in
the discharge refrigeration line from the
compressor to the remote condenser. A trap is
necessary for every additional 25 ft (7.62 m)
vertical rise. When excessive vertical rise exists,
this trap allows oil to reach the condenser and
return to the compressor.
3. The easiest method to create a trap is to bend the
tubing (smoothly, no kinks) into the trap form.
