OWNER’S MANUAL
REMOTE CONDENSER INSTALLATION GENERAL
The remote condenser is normally located outdoors.
Proper clearances must be maintained around unit to allow
for service and maintenance. The intake of the remote must
be at least 36” from any obstruction.
IMPORTANT
The outdoor remote condenser must be installed above
or at the same level as the dehumidifier. When installing
the remote condenser below the dehumidifier more than
eight feet, the factory must be consulted.
Hot gas and liquid line sizes that are stated on the unit
and in the installation manual must be adhered to. The
length of run of these lines must be 50 feet or less. Contact
factory for runs over 50 feet.
THE DCA DEHUMIDIFIER IS A FLOODING HEAD PRESSURE
CONTROLLER SYSTEM
Refer to the following chart when determining the
required amount of additional refrigerant 22 to be weighed
into system when corresponding remote condenser is
added. Refrigeration lines (field supplied) should not exceed
50 feet in length. Contact DCA when longer lengths are need.
ATTENTION INSTALLERS
Only trained, qualified personnel should install or service
DCA equipment. Serious injury, death and property damage
can result from improper installation/service of this
equipment. High voltage electrical components and
refrigerant under pressure are present.
REFRIGERANT PIPING OF REMOTE CONDENSER
Refrigerant piping (supplied by others) must be
dehydrated copper. Standard refrigerant practices must be
used when a remote condenser is installed. Both outgoing
and incoming refrigerant lines must be insulated to prevent
dripping. Hot gas lines should have traps installed every 20
feet of vertical lift. The remote condenser is shipped with a
nitrogen holding charge. Remove this charge at the access
ports provided before attempting to evacuate system. Refer
to the following chart to determine the correct remote
condenser line size required.
Service valves on the main unit are located in the blower
compartment. Keep these service valves closed (front
seated) until all soldering, evacuation and refrigerant
charging is completed.
When installing line set, make sure that all solder joints
are clean, oil free and absent of any foreign material. Insert
copper into valve until line bottoms out in valve. Complete
soldering process. Pressurize line set to determine if any
leaks are present. Repair leaks, if any, and evacuate line sets
and remote condenser down to 500 microns. Once the
evacuation procedure has been completed, pressurize
system with refrigerant and leak check with electronic
detector. if no leaks are found, you can add additional
refrigerant to the system.
Do not open service valves to remote condenser until all
additional refrigerant is added. Refrigerant should be added
at the remote condenser coil.
In the event the remote condenser coil will not accept all
the additional refrigerant needed, add remaining at the
receiver in the dehumidifier. The receiver is equipped with
rotolock valves. Do not add refrigerant at the suction port of
the unit. This could cause the compressor to slug with liquid
refrigerant
AND VOID THE WARRANTY.
Remote condenser coil must be kept clean from any
grass clippings, leaves, dirt, etc. Failure to keep coil clean will
result in poor unit performance and high operating costs. Do
not cover remote condenser during cold months. Proper
dehumidification requires year-round operation of remote
condenser.
