living quarters.
- All units meet
or exceed applicable ABYC and U.S. Coast Guard regulations, CE
Directives and general Air Conditioning and Refrigeration
Industry (ARI) standards.
|
| Advantages
of M.A.S. Chilled Water System vs. Direct Expansion Spilt System |
- No refrigeration
line sets and mechanical flare fittings which are subject to
leaking refrigerant over time - thus eliminating refrigerant
repair within living quarters.
- Environmentally
friendly as hermetically sealed modules.
- No EPA certified
technician required for startup or field installation.
- Flexible hose is
easier to install and insulate compared to semi rigid cooper
refrigerant line sets.
- Provide full
cooling capacity to areas which require fast pull downs from hot
starts.
- Most
applications result in fewer number of compressors which
increases reliability, reduces weight and conserves power.
- Multiplexed
chiller installations typically realize a 50% power savings over
24 hour period.

| *Model
number breakdown: CHC= Chiller Compact; 16, 20, 24 = BTU/H x 1000;
RC = Reverse Cycle; Z = 230VAC; S = Scroll Compressor (Rotary
compressors are used on the 16 & 20). |
| **Standard
models operate at 60Hz and 50Hz. However, there is a 17% reduction
in capability when operating at 50Hz. Full capacity 50Hz only units
are available upon request (220/240V only). |
| ***Add
1.0/2.5cm for each mounting bracket. The four brackets supplied can
be mounted on any side of base pan (depth or width). |

| Installation
Guidelines for Chiller Compact |
| When
choosing the proper model CHC Chiller Compact condensing unit,
primary consideration should be given to calculate BTU loads and
available power supply. The location of the Chiller Compact
condensing unit should be dry and accessible for service typically
in engine room, lazarette or machinery compartment. 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. Do not stack
units directly on top of each condensing unit must be independently
supported. Racking is available to facilitate custom installations.
Reinforced marine grade hose is to be used for ht seawater circuit.
The hose has to be routed upwards from the thru-hull intake to the
condensing unit to prevent air locks in the centrifugal seawater
pump. Circulation connections between the condensing unit and the
chilled water lines are to be made with properly sized fittings and
reinforced marine grade hose. All hose connections are to be double
clamped and ball valves should be installed at chilled water
inlet/outlet of each CHC unit and each air handler for ease of
serviceability of the system. Insulate all hose and fittings air
tight upon completion of leak tests to prevent condensation and
capacity loss. |
The
condensing unit 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. Never install the air handlers in bilge or engine room areas
and insure that the selected location is sealed from direct access
to bilge and/or engine room vapors. Do not terminate condensate
drain lines within four (4) feet of any outlet of engine or
generator, nor in the bilge (vapors can travel up the drain line),
unless the drain is connected properly to a sealed condensate or
shower sump pump. Failure to comply may allow bilge or engine room
vapors to mix with the air conditioners return air and contaminate
the living areas. 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 pre-wired for power with solid state
control circuits. The system control switch can either be mounted on
the module or remote on a panel for convenient access. All chilled
water condensing units use closed-refrigerant circuits, pre-charged
with R-22. No additional refrigerant 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 circuits.
However, this is not necessary when installing Chiller Compact. |
