PCS1 Specifications
DESCRIPTION OF OPERATION: Solar radiation bombards the house’s roof
structure throughout the day. The roof functions as a “solar collector.” Solar
radiation reaches the attic through a process called “conduction.” The attic
functions as a storage and heat transfer area. The PCS1 is physically located inside
the attic and then transfers this solar radiation from the attic air into the swimming
pool’s water through a process called “forced air convection.”
FULL AUTOMATIC OPERATION: Is achieved with the optional LX220 control.
When the attic is eight degrees hotter than the pool and the pool needs heat, the
LX220 automatically routes water up to the PCS1 and turns it on. It can even
synchronize the pool’s pump by turning it on at the same time.
SECTION 1 - SYSTEM ARRIVAL Page S1-2

SECTION 1 - SYSTEM ARRIVAL Page S1-3
Temperature sensors sense the pool and attic temperatures. Maximum heat is then
extracted automatically. The pool owner simply sets the desired thermostat setting
on the LX220. Flowreversalª can substantially reduce the poolÕs heat demand by
allowing the heat to rise from the main drain. Flowreversalª is a trademark of
Mark Urban, Tustin, California. A pool blanket can be used when the pool is not in
use thereby minimizing heat losses caused by evaporation (60%). Specifications are
subject to change without notice.

Limited Warranty
All PCS1 convection units are warranted to be free from defects in material and
workmanship for a period of eighteen months from the date of shipment from the
factory. This warranty covers all parts and labor to correct manufacturing defects,
but does not cover incidental fin damage nor any corrosive damage to heat transfer
coils caused by improperly maintained chemical Ph levels in pools. Ph levels
outside of the 7.2 to 7.6 range void warranty. Use in salt water pools voids warranty.
Corrugated fins are used on the heat transfer coils for improved efficiency. They are
waffled in appearance and not straight. Fin bending that has been combed with a fin
tool does not affect performance and is not considered a manufacturing defect. Our
obligation under this warranty is limited to the repair or replacement, at our factory,
of any part or parts which, upon our examination, have proven to be defective.
Correction of such defects by repair or replacement (at our option) and return freight
via lowest common carrier, shall constitute fulfillment of SolarAttic, Inc.Õs
obligation to the purchaser.
This warranty does not apply to those products which, in our judgment, have been
altered or repaired outside our factory, or subjected to misuse, negligence, accident,
corrosive atmospheres, or operating beyond the limits of our design.
THIS WARRANTY CONSTITUTES THE BUYERS SOLE REMEDY. IT IS GIVEN IN LIEU OF ALL
OTHER WARRANTIES. THERE IS NO IMPLIED WARRANTY OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE. WHERE CIRCUMSTANCES CAUSE REMEDY
EXPRESSED HEREIN TO FAIL OF ITS ESSENTIAL PURPOSE, SOLARATTIC, INC'S LIABILITY
SHALL NOT IN ANY EVENT EXCEED THE PURCHASE PRICE. IN NO EVENT, SHALL
SOLARATTIC, INC BE LIABLE FOR CONSEQUENTIAL OR INCIDENTAL DAMAGES, WHETHER
THE THEORY BE BREACH OF THIS OR ANY OTHER WARRANTY, NEGLIGENCE, OR STRICTLY
TORT. DISPUTES ARISING UNDER THIS AGREEMENT SHALL BE GOVERNED BY APPLICABLE
MINNESOTA LAW.

DIALOG MANUAL
Thank you for your purchase! This manual is the PCS1 installation, technical
support, and reference manual. It is not necessary that you read every page. Instead,
you may wish to read only those sections that you are concerned about. The
material provided in this manual is very detailed and is considered sufficient
enough for the skilled or semi-skilled craftsman to install the PCS1 system.
This manual provides a ÒdialogÓ and discussion of the issues involved in the
technical literature. The dialog covers areas that may not be readily apparent from
the technical literature itself [drawings, diagrams, etc.].
This ÒdialogÓ or discussion type of manual can be contrasted to a Òstep by
stepÓ manual where all known installation factors are the same in every instance.
In such a case, the installation manual could then take you from step A to step Z --
one step at a time. Due to the unlimited variations in swimming pools, their
support systems, and the homes in which the PCS1 is installed -- a Òstep by stepÓ
manual is not feasible. This manual, therefore, explains all of the technical issues
and provides the installer with a general installation process to follow.
Having explained the technical issues, the installer must then apply the
general installation process to the specific pool and home involved. Do-it-
yourselfers can install this product using this manual if they have the appropriate
skills involved. These are primarily electrical and pvc plumbing skills. Again, since
this is an ÒissuesÓ and ÒdialogÓ manual, the do-it-yourselfer must also be able to
apply the knowledge provided to the actual installation site.

SECTION 1 - SYSTEM ARRIVAL Page S1-6
CAUTIONS
The following pages are CAUTION
notes designed to inform you of the
existence of hazardous areas. They
will help prevent personal injury and
fatalities. They will also help prevent
damage to equipment, swimming pool
systems or to the house.
MAKE SURE YOU READ AND UNDERSTAND
ALL OF THESE CAUTION NOTES!!!
CHILDREN CAUTION
SEVERAL SHARP EDGES ON THE PCS1 CAN CAUSE CUTS OR INJURIES.
THIS IS NOT A PRODUCT THAT CHILDREN SHOULD BE ALLOWED TO TOUCH.
THEIR NATURAL CURIOSITY CAN RESULT IN INJURY OR ACCIDENT. **KEEP
ALL CHILDREN AWAY FROM THIS PRODUCT TO PREVENT INJURY OR
ACCIDENTS**

SECTION 1 - SYSTEM ARRIVAL Page S1-7
ELECTRICAL CAUTION
DANGER: THIS PRODUCT USES 220 VAC AND CAN CAUSE A FATAL
INJURY. THE MANUAL ASSUMES AN EXPERIENCED ELECTRICIAN IS BEING
EMPLOYED. ALL ELECTRICAL WIRING MUST BE DONE IN ACCORDANCE
WITH APPLICABLE CODES.
PLUMBING CAUTION
THIS PRODUCT REQUIRES PVC CEMENT WELDING AND THE MANUAL
ASSUMES AN EXPERIENCED PLUMBER IS BEING EMPLOYED. DO NOT ACCEPT
ANY LEAKING PVC JOINTS. DO NOT ÒLEARNÓ PVC CEMENT WELDING ON
THE EXPENSIVE POOL VALVES PURCHASED. DAMAGE TO THE VALVES
FROM POOR PVC WELDING IS NOT COVERED BY THE MANUFACTURERS
WARRANTY. ASSEMBLE THE VALVES AND PIPES BEFORE WELDING TO
MAKE SURE THEY FIT PROPERLY. THIS IS CALLED A PRACTICE RUN BEFORE
ACTUAL PVC CEMENT WELDING OCCURS AND INSURES YOUR PARTS ARE
READY FOR PERMANENT CEMENTING.
PLUMBING CAUTION
DO NOT USE DRAIN-WASTE (HOUSE SINK OR DRAIN) PVC FITTINGS
(45°OR 90°ELBOWS, STRAIGHT SXS FITTINGS, ETC.) ON YOUR POOLÕS
SUPPORT SYSTEM RE-ASSEMBLY. USE SCHEDULE 40 PVC FITTINGS. THE
DRAIN-WASTE PVC FITTINGS DO NOT HAVE THE SAME DEPTH OF PVC PIPE
PENETRATION WHICH COULD RESULT IN THE POOLÕS PVC PIPE POPPING
AWAY FROM THE SHORTER DRAIN-WASTE PVC FITTING (ELBOW, ETC.).

SECTION 1 - SYSTEM ARRIVAL Page S1-8
FIN CAUTION
THE FINS ON THE PCS1 COIL ARE SHARP AND CAN CAUSE A RAZOR-
LIKE CUT IF YOUR HAND OR ARM COME INTO CONTACT WITH THEM. TAKE
APPROPRIATE CARE DURING INSTALLATION AND DO NOT COME INTO
DIRECT CONTACT WITH THE FINS OF THE COIL. IF THE COIL FINS ARE
ACCIDENTALLY DAMAGED, THEY CAN BE ÒCOMBEDÓ STRAIGHT WITH A FIN
COMB [10 FINS PER INCH].
GRILLE CAUTION
THE PROTECTIVE GRILLE HAS SHARP EDGES WHICH CAN CUT YOUR
FINGER OR HANDS. EXERCISE CAUTION WHEN HANDLING, REMOVING OR
INSTALLING THIS GRILLE.
FAN CAUTION
DO NOT OPERATE THE PCS1 WITH THE FAN GUARD PROTECTIVE
GRILLE REMOVED. THE PROTECTIVE GRILLE IS TO PREVENT HARM WHILE
THE FAN IS OPERATING. UNPLUG THE CONVECTION UNIT [PCS1] DURING
SERVICE AND ENSURE THAT THE FAN BLADE HAS STOPPED ROTATING. IF
THE FAN BLADE HAS BEEN CHANGED, ENSURE THAT THE NEW BLADE IS
TORQUED DOWN TO 120 INCH POUNDS AND THAT LOCTITE HAS BEEN
APPLIED TO THE THREADS OF THE LOCKING SCREW.

SECTION 1 - SYSTEM ARRIVAL Page S1-9
MOTOR CAUTION
DO NOT OPERATE THE MOTOR FOR AN EXTENDED TIME WITHOUT
THE FAN BLADE ATTACHED. THE MOTOR IS A ÒTOTALLY ENCLOSED AIR
OVERÓ MOTOR [TEAO] AND THE AIR FLOW OVER THE MOTOR FROM THE
FAN BLADE PROVIDES COOLING FOR THE MOTOR. OPERATING THE MOTOR
WITHOUT THE FAN BLADE ATTACHED WILL LEAD TO THE MOTOR OVER
HEATING AND A THERMAL CUTOFF OF THE MOTOR [INTERNALLY].
TEKS SCREW CAUTION
DO NOT REPLACE ANY SELF TAPPING #10-1/2 TEKS SCREW USED ON
THE PCS1 REAR COIL SIDE WITH ANY SHEET METAL SCREW GREATER
THAN ONE-HALF INCH (1/2Ó) IN LENGTH. DOING SO CAN DAMAGE THE
PCS1 WATER COIL BY PUNCTURING ONE OF THE COILÕS WATER PIPES OR
MANIFOLDS.
WEIGHT CAUTION
THE PCS1 WEIGHS 240-253 LBS CRATED AND 135 LBS UNCRATED. IN
ADDITION, THE UNIT IS BULKY. CAUTION SHOULD BE TAKEN WHEN
LIFTING THE UNIT SO AS NOT TO TWIST FROM THE WAIST OR TO PLACE A
BURDEN ON THE LOW BACK. NO ATTEMPT SHOULD BE MADE TO LIFT THE
UNIT ALONE. TWO OR MORE MEN SHOULD BE PRESENT. ATTEMPTING TO
LIFT OR HANDLE THE PCS1 ALONE CAN LEAD TO PHYSICAL INJURY.

SECTION 1 - SYSTEM ARRIVAL Page S1-10
POOL CHEMISTRY CAUTION
AN IMPROPERLY MAINTAINED POOL WILL TURN ACIDIC VERY FAST
AND DAMAGE ALL OF THE POOLÕS SUPPORT EQUIPMENT INCLUDING THIS
HEATER. MAINTENANCE OF POOL WATER CHEMISTRY IS A SERIOUS
RESPONSIBILITY OF OWNING A SWIMMING POOL. NOTE: IF YOUR POOL
WATER IS CRYSTAL CLEAR, DRINKABLE AND DOES NOT SMELL OF
CHLORINE -- YOU HAVE THE RIGHT POOL CHEMISTRY. CHECK WITH YOUR
LOCAL CHEMICAL DEALER IF YOUR POOL DOES NOT HAVE THESE
ATTRIBUTES!
BUILDING CODE CAUTION
INSTALL ALL EQUIPMENT IN ACCORDANCE WITH LOCAL, STATE AND
NATIONAL CODES TO PREVENT INJURY, FATALITIES OR DAMAGE TO
EQUIPMENT.
SERVICE CAUTION
UNPLUG THE PCS1 BEFORE ATTEMPTING ANY SERVICE! SERVICE
SHOULD NOT BE ATTEMPTED BY AN INEXPERIENCED TECHNICIAN
WITHOUT FIRST READING THIS ENTIRE MANUAL!
SERVICE CAUTION
DO NOT CREATE A SITUATION THAT WOULD ALLOW POOL WATER
TO BE INADVERTENTLY ROUTED TO DISCONNECTED ATTIC PIPES. IF THE
PCS1 IS DISCONNECTED FROM THE ATTIC PIPES, DISCONNECT THE PUMP
AND REMOVE THE VALVE CONTROLS AND HANDLES DURING SERVICE. OR
RECONNECT A BYPASS PIPE IN PLACE OF THE PCS1 DURING ITS REMOVAL.

SECTION 1 - SYSTEM ARRIVAL Page S1-11
FACTORY SHIPMENT
BOXES SHIPPED
The PCS1 convection unit is shipped in a custom designed crate. It is shown
on the page after next. When ordered with the PCS1, the LX220 solar controller and
valve(s) are packed inside the crate to the right of the PCS1. On occasion, the
controller and valve(s) MAY be shipped separately in one or more additional boxes.
All of these boxes would then be identified separately on the shipping manifest. If
more than one box [including crate] is shipped, each will be identified by a number
within a total number. For example: 1 of 2; 2 of 2; etc. In this way, you will know if
you have received all of the boxes that are a part of your shipment. In the preceding
example, 2boxes should have been received.
LOCATION OF SENSORS
Both the water and attic temperature sensors are located inside the LX220
solar controller behind the front panel. See page S3-49 drawing. Using a phillips
screwdriver, unlock the front panel door and open the hinged panel. Both sensors
are located in the lower (high voltage) compartment near the Ògrounding bar.Ó See
page S3-51 for a drawing of the LX220Õs internal compartments.
SHORTAGE CLAIM
IF YOU HAVE NOT RECEIVED ALL OF THE BOXES IDENTIFIED BY THE
TOTAL NUMBER -- WRITE THIS DIRECTLY ON THE MANIFEST AS A
SHORTAGE!! IDENTIFY WHICH BOX OR EQUIPMENT WAS NOT RECEIVED.
DO NOT ALLOW THIS SHORTAGE TO GO UNDOCUMENTED. YOU HAVE TO
FILE A CLAIM WITH THE SHIPPER -- IMMEDIATELY -- [AT THE TIME OF
RECEIPT] IF ALL OF THE BOXES DID NOT ARRIVE. UNDER THE FACTORIES
SHIPPING TERMS OF FOB, YOU OWN TITLE TO THE EQUIPMENT WHEN THE
FACTORY PLACES THE EQUIPMENT ON THE CARRIER. IN OTHER WORDS,
WHEN THE EQUIPMENT LEAVES THE FACTORIES DOCK -- YOU OWN IT. A
SHORTAGE MEANS YOUR PROPERTY HAS BEEN LOST BY THE CARRIER. THE
CARRIER MUST EITHER FIND IT OR PAY FOR IT.

SECTION 1 - SYSTEM ARRIVAL Page S1-12
DAMAGED EQUIPMENT
THE EQUIPMENT LEFT THE FACTORY INTACT. IF IT IS RECEIVED IN A
DAMAGED CONDITION, THE CARRIER MUST PAY FOR THE DAMAGE. FILE A
CLAIM -- IMMEDIATELY -- IF THE EQUIPMENT IS RECEIVED IN A DAMAGED
CONDITION. THIS INCLUDES INTERNAL DAMAGES!! USUALLY, IF THERE IS
NO EXTERNAL DAMAGE -- THERE PROBABLY IS NO INTERNAL DAMAGE.
HOWEVER, THIS IS NOT ALWAYS THE CASE. IF THE EQUIPMENT HAS BEEN
DROPPED FROM A FORKLIFT, FOR EXAMPLE, INTERNAL DAMAGE COULD
OCCUR WITHOUT EXTERNAL DAMAGE BEING APPARENT. IF YOU ACCEPT
DELIVERY WITHOUT OPENING AND INSPECTING THE PARTS AND FIND
DAMAGED GOODS INSIDE -- CALL THE CARRIER UP IMMEDIATELY AND FILE
A DAMAGE CLAIM. THE CARRIER WILL WANT TO COME OUT AND INSPECT
THE GOODS. DO NOT CONTINUE UNPACKING WHEN DAMAGE IS FOUND.
VISIBLE EXTERNAL DAMAGE
IF A CORNER OF A CRATE OR BOX IS CRUNCHED INWARD, THIS
MEANS THAT THE BOX HAS BEEN DROPPED OR THROWN ONTO ITS
CORNER. THE RESULT COULD BE INTERNAL DAMAGE TO THE PARTS DUE
TO CARRIER MISHANDLING ALONG THE SHIPPING ROUTE. IF THERE ARE
ANY SIGNS OF EXTERNAL DAMAGE TO THE BOXES, MAKE A NOTE OF THIS
ON THE CARRIERS DELIVERY MANIFEST. IF POSSIBLE, INSPECT THE
SHIPMENT INTERNALLY WHILE THE DELIVERY PERSON IS STILL PRESENT.
THIS WILL HELP PREVENT ANY CLAIMS CONFLICT WITH THE CARRIER
SHOULD DAMAGE BE FOUND.

DAMAGE INSPECTION
EXTERNAL INSPECTION
1. Inspect all sides of the shipping crate for any sign of damage. No external damage
should be visible. Be sure to inspect the bottom of the shipping crate!

SECTION 1 - SYSTEM ARRIVAL Page S1-14
2. Make note of any visible external damage on the shipping manifest to document
a potential claim against the carrier. If possible, when you find external damage,
make an internal inspection of the goods in the presence of the delivery person.
NOTE: Do not sign the receipt of the goods [manifest] until you are satisfied you
have received the goods intact [undamaged] and/or have documented ON the
manifest any claims you may have against the carrier.
3. File a claim with the carrier, immediately, if any internal damage to the
equipment is found.
INTERNAL INSPECTION
1. Remove the front plywood panel of the crate.
2. Remove the front foam insert.
3. Carefully rip open the plastic bag covering the PCS1.
4. Inspect to see that the motor is still in place and attached to the motor arms.
5. Inspect to see that the motor arms are still in place and attached to the venturi.
6. Inspect to see that no damage to the coil fins has occurred from shipping.
NOTE: internal damage caused by dropping the crate could sever one or more
motor mounting brackets which would free the motor and could cause fin
damage and damage to the fan blade, etc.
7. Verify the fan blade is free to rotate in the venturi and is not obstructed.
8. Remove the right panel to inspect the electronic control and valve(s).
9. Remove the rear panel to inspect the coilÕs pipe threads and fins if desired.
REUSE SHIPPING MATERIALS
The shipping materials can be reused in the installation of the PCS1. The
plywood can be used as a base in which the PCS1 can rest on and the foam can be
used under the PCS1 to dampen any vibration present from the PCS1. NOTE: a
small amount of vibration is normal from the PCS1 convection unit. Use of one or
more layers of foam under the PCS1 dampens this small vibration and prevents it
from radiating into and along rigid structures. The plywood can be further used in
the reframing of an attic access opening. Other uses of the crate materials become
obvious depending upon site conditions.
