INSTALLATION — REMOTE CONDENSING UNITS
Prior to installing the condensing unit, test the electrical service to assure that it agrees with the
specifications on the data plate located on the condensing unit frame.
GENERAL
The Model HQC135 Chiller can be purchased with a remote condensing unit. The HQC200 will always
be provided with a remote condensing unit. Condensing unit sizes are 3 or 3
1
/4 HP for HQC135 and
5
HP for HQC200. Condensing units are available for indoor air-cooled, indoor water-cooled or outdoor
application, to be specified at time of order. Compressor is available in hermetic or semi-hermetic
types for HQC135 and HQC200.
DUE TO THE VARIED NATURE, COMPLEXITY AND UNIQUENESS OF REMOTE CONDENSING
UNIT INSTALLATIONS, THE HOBART WARRANTY DOES NOT COVER REMOTE INSTALLATION
WORK AND DOES NOT COVER CONDENSING UNITS SUPPLIED BY OTHERS.
ELECTRICAL CONNECTIONS
WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE
APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL
ELECTRICAL CODES.
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE
DISCONNECT SWITCH TO INDICATE THAT YOU ARE WORKING ON THE CIRCUIT.
Install electrical conduit and wiring (not supplied) from the power supply to the terminal junction box
on the condensing unit. Proper supply voltage, maximum fuse/circuit breaker sizes and minimum
circuit amperage can be found on the condensing unit data plate. On outdoor condensing units, wiring
must be encased in watertight conduit and use watertight fittings.
It is recommended that a disconnect switch (not supplied) be located near the remotely installed
condensing unit for installing or servicing.
Refer to page 13.
CONDENSER RECOMMENDATIONS
For indoor installations, place the condensing unit in a cool, dry place that is easily accessible for
installation, cleaning and maintenance. The condenser must be located a minimum of 2 feet from a
wall or obstruction. For air-cooled condensing units located in machine rooms or air restricted areas,
ventilation is needed to dissipate the heat produced by the condenser. The condenser heat varies
during the chilling cycle but could be considered for ventilation purposes to be as follows:
3 or 3
1
/4 HP Condensing Unit 50,000 BTU/h
5 HP Condensing Unit 73,000 BTU/h
