size unit. |
| **
Cooling and heating capacities are given at performance ratings of
100°F (38°C) condensing temperature and 35°F (2°C) evaporating
temperature. |
| ***
High voltage (460/380) and three phase specifications are available
upon request. |
| ****
Add 1.0”/2.5cm for each mounting bracket. The two brackets
supplied can be mounted on any side of base pan. |
| *****
Electrical box may be remotely mounted (except for MCW16). If
mounted on unit, add 2.5”/6.4 cm to height dimension.
Note:
1. Standard models operate at 60 Hz and 50 Hz. However, there is a
17% reduction in capacity when operating at 50 Hz. (Full capacity 50
Hz only units are available upon request.)
2. Low voltage (24VAC) control circuits are available for
multiple-staged systems. |

| Installation
Guidelines for Modular Chiller |
| When
choosing the proper model MCW Modular Chiller condensing unit,
primary consideration should be given to calculated BTU loads and
available power supply. Any special requirements (capacity
modifications, voltages, cycles, auxiliary heat, etc.) should be
determined prior to installation.
The location of the MCW Modular
Chiller condensing unit should be dry and accessible for service.
Secure the condensing unit to a level horizontal surface with the
supplied brackets. These brackets are designed to hold the weight of
the equipment as well as handle any torsional movement. If a Marine
Air Systems frame base is supplied and the chillers are already
mounted, secure by drilling through the frame base at convenient
locations. Do not stack units directly on top of each other. Each
condensing unit must be independently supported.
Reinforced marine grade hose is to be
used for the sea water circuit. The hose is to be routed upwards
from the thru-hull intake to the condensing unit to prevent air
locks in the centrifugal sea water pump. Circulation connections
between the condensing unit and chilled water lines are to be made
with properly sized fittings and reinforced marine grade hose. All
hose connections are to be double clamped. Ball valves should be
installed at chilled water inlet/outlet of each MCW unit and each
air handler for overall serviceability of system. Insulate all hose
and fittings properly upon completion of leak tests to prevent
condensation and energy or capacity loss. |
The
chassis has an integral condensation drain pan for removal of any
water that may form. Secure a hose to this drain pan spud and route
it downward to a proper sump or overboard discharge outlet.
All circuit breakers and wire gauge
must be sized according to marine design standards. Only stranded
tinned copper wire should be used. Route all wiring through the
strain-relief connectors provided in the electrical boxes.
All equipment should be properly
grounded using the grounding lug provided on each unit’s chassis.
Electrical boxes are pre-wired for power and control circuits.
Mechanical control panels can be remote mounted in a convenient
location, using the four mounting screws provided. Field wiring is
required between remote switch and unit electrical box.
All chilled water condensing units use
closed-refrigerant circuits, pre-charged with R-22. No additional
refrigerant is required during the installation or at initial
start-up and operation of the system. Refer to other individual
component sheets for specifications and details of air handlers,
controls and related parts.
In keeping with regulations set forth
by the EPA, only certified technicians should perform service on, or
make adjustments to, any refrigerant circuit. |

specifications and design as outlined herein are subject to change without
