INTRODUCTION

DCA Series
Congratulations! You have purchased the finest
equipment available to control damaging humidity
associated with indoor pools and spa areas.
DCA dehumidifiers are precision engineered products,
specifically designed to control the conditions in your
indoor pool room to obtain maximum performance and
energy savings.
Your DCA dehumidifier has been carefully assembled
and tested at our factory by our trained personnel. Only
Skilled, Trained and Qualified Personnel may install and
service your DCA equipment.
DCA cannot possibly anticipate every possible
circumstance that might involve a hazard. The warnings in
this manual and on tags and decals affixed to the
equipment are, therefore, not all-inclusive. If you use a
procedure, work method or operating technique not
specifically recommended by DCA, you must satisfy
yourself if it is safe for you and others.
CAUTION
Serious injury, property damage and death can result from
unqualified personnel installing and servicing this equipment.
High pressure refrigerants and high electrical voltage are
present.
IMPORTANT
Your DCA dehumidifier is one of several essential
components that is necessary in your pool room for
complete environmental control. The following areas must
be incorporated in your pool room by you, your contractor,
engineer and architect.
• HUMIDITY CONTROL
• DUCT DESIGN
• AIR DISTRIBUTION OVER EXTERIOR
GLASS AND SKYLIGHTS
• VENTILATION
• BUILDING CONSTRUCTION
• POOL WATER CHEMISTRY
• ADEQUATE POOL ROOM VAPOR BARRIER
• PROPER WALL & CEILING INSULATION
• LOW “E” GLASS & SKYLIGHTS
• PROPER STORAGE OF POOL & SPA
WATER CHEMICALS
A pool room dehumidifying system will not provide
desired comfort and building protection unless these areas
are addressed.
Important information about each of these areas are
included in this manual. It is the responsibility of the owner
along with the contractor, engineer and architect to ensure
that careful consideration be given to all of these areas of
pool room environment control.
A DCA dehumidification system can handle all of your
moisture removal needs and in many cases your heating
and cooling requirements.
Dehumidification is accomplished by moving room air
through the dehumidifying coil, lowering the air
temperature below its dew point. Moisture will condense
on this coil thus removing a large portion of the moisture
from the air. The heat recovered by the above mentioned
process, known as latent heat, and the electrical
consumption of the compressor is delivered by the reheat
condenser coil. The air leaving the evaporator coil enters
the reheat condenser coil and picks up the available heat
and exits the dehumidifier as warm dry air.
With the addition of an air cooled remote condenser, a
majority of the room cooling can be achieved during the
warm months. If the room temperature should rise above
the preset condition, the system will switch from delivering
warm dry air to delivering cool dry air automatically. As
stated above, the DCA system will control moisture and in
many cases heat and cool the pool room enclosures.
Proper installation by qualified personnel of the
dehumidifying system in the total pool room environmental
control system takes careful planning and is very important
for achieving desired results. With a seasonally fluctuating
load, supplemental heaters must be added to compensate
for any heat loss that may be needed to compensate for
any heat loss that may be needed to compensate for the
lack of heat from dehumidification. The supplemental heat
source must be sized to handle the total heating
requirements.
UNPACKING & INSPECTION
All DCA Systems are completely factory tested to
ensure proper operation before shipment. Check for
shipping damage both internal (concealed) and external.
NOTATION MUST BE MADE ON CARRIERS FREIGHT
BILL OF LADING TO INSURE PROMPT FREIGHT DAMAGE
CLAIMS PROCESSING.
Claims for freight damage or shortages must be filed
within 5 days of acceptance of equipment with the
delivering freight carrier. All Freight Claims must be
resolved with the delivering freight carrier. The factory
cannot be of any help after equipment is signed for and
delivered.
LOCATION AND MOUNTING
Unless authorized by DCA all units must be installed in
equipment rooms and areas that do not fall below 45° F.
Considerations must be made for service access,
electrical requirements, duct work and filter access on all
units.
It is extremely important that, if the dehumidifier is
suspended, the ceiling structure and hanging apparatus be
of sufficient capability to adequately support the weight of
the dehumidifier. Check dehumidifier weight to make
determination. Secondary drain pan, under dehumidifier, is
required and supplied by others.
NOTE:
CLEARANCE OF 18” TO 24” IS RECOMMENDED ON TOP,
BOTTOM AND ALL SIDES FOR SERVICE OF COMPONENTS
SUCH AS FILTERS, MOTORS, BELTS AND OTHER
ELECTRICAL AND REFRIGERATION COMPONENTS.
