- Page 2 But MAKE NO MISTAKE - We have invented, designed and pioneered most of what has become the swimming pool heat pump of today. Heat Siphon® was the first pool heater to use a titanium heat exchanger, the Copeland Scroll compressor and vacuum formed PVC cabinets. We are the only pool heater manufacturer using a patent pending electrically isolated heat exchanger backed by an unconditional lifetime full replacement corrosion warranty.

Just like a room air conditioner moves 2 to 3 units of heat from your home for every unit of electricity it consumes, Heat Siphon® uses 1 unit of electric energy to move 4 units of heat from the air and thus it provides 5 units of heat to your pool. -
Page 6: Heat Siphon® Exterior Parts
Don’t Void Your Warranty! This section contains all the information you will need to ensure that your Heat Siphon® has been properly installed. Read this section before allowing a new dealer to install your unit. If your installer is not an Authorized Heat Siphon®... -
Page 7: Use A Qualified Installer
4.2 Locating Your Heat Siphon® As long as you provide plenty of fresh air and give it adequate clearance space all around, Heat Siphon can be installed virtually anywhere outdoors. Unlike gas heaters whose pilot lights can be blown out, Wind has no effect on Heat Siphon®... -
Page 8: Provide Full Flow - No Bypass
It won’t rust, fade, chip or peel. If the air temperature drops below about 42°F while the Heat Siphon® is running then any water in the air will begin to freeze and form frost or ice on Heat Siphon’s large horseshoe shaped evaporator fins. -
Page 9: Pool Heating Considerations
Heat Siphon® is equipped with a flow sensing switch which turns it on and off automatically when the pool pump is turned on or off. However, you must still run the pool pump long enough each day to allow Heat Siphon®... -
Page 10: Pool Pump Run Time
5.2 Pool Pump Run Time Just like other pool heaters, Heat Siphon® can add heat to the pool only when the filter pump is running. So the question is how many hours a day do you run your pool pump- 24, 16, 12 or 8 hours per day? NOTE: In ANY given pool or spa piping system, if you DOUBLE the flow rate, you QUADRUPLE the WATTS needed to pump water thru it. -
Page 11: Owner Troubleshooting
6 Owner Troubleshooting The purpose of this section of the manual is to provide some GUIDANCE FOR HEAT SIPHON® OWNERS with little or no technical background who have a problem with their Heat Siphon®. -
Page 12: Unit Tries To Start Then Does Nothing
3. Is the pool filter clean and pool water flow stable? A clogged filter or air leak in the pool pump return line can cause erratic water flow and air in the lines which in turn can cause Heat Siphon® to cycle- restore the correct water flow. -
Page 13: Maintenance & Winterizing
CAP DUE TO FREEZING. If you have not properly winterized (See next section) this will not be covered under your warranty. Before calling your dealer, here are some tests you should perform: 1. TURN OFF YOUR HEAT SIPHON, KEEP YOUR POOL PUMP ON and wait until basepan empties. If the Water Leak Stops IT IS NORMAL CONDENSATION 2. -
Page 14: Cleaning
ELECTRIC SHOCK HAZARD. Heat Siphon’s solid PVC cabinet may be cleaned using any of the automotive vinyl cleaners, or soap and water. An abrasive cleaner or bathtub porcelain cleanser will remove most stubborn stains. Dirt and leaves should be swept from the finned horse shoe shaped evaporator if build up occurs. -
Page 15: Installer Section
Black acrylic enamel spray paint can also be used to repair any cosmetic damage. 1.1 Moving & Handling Precautions If only a few simple handling rules are followed, Heat Siphon® can be moved virtually anywhere with no problems: 1. DO NOT DROP OR TAILGATE THE HEAT SIPHON . -
Page 16: Planning Installation
3. DO NO LIFT THE HEAT SIPHON® BY ITS TOP / VENTURI - USE HAND HOLES IN BASE. Use a fork truck, roller conveyor or an inclined plane to unload the Heat Siphon® carton. Although the special PVC plastic used in the HEAT SIPHON® cabinet is extremely tough and more than adequate for shipment even in cold weather, it will probably break or crack if dropped from a truck tailgate. -
Page 17: Physical Location
In addition, the following guideline should be adhered to when picking the location: 1. Allow 24 to 36 inches of open area all around the Heat Siphon® for good air circulation and service access. Avoid any overhangs or structures which could cause exhaust air to recirculate from the top of the unit back into the sides. -

C & Z 200, 250,375 & 575 series heating only and cooling only models: Heat Siphon’s exclusive FULL FLOW Titanium heat exchanger has a minimal pressure drop and requires NO SPECIAL PLUMBING arrangement. It should be considered as just another length of PVC pipe in your pool filtration system. -

Page 23: Multiple Units
Indoor installations of Heat Siphon® not only heat the pool, but provide the added benefit of dehumidification of the pool room. When the Heat Siphon® cools down the room air to extract heat out of it, the moisture in the air condenses on the cold evaporator, thus drying the air. -

This is to give the water pump time to push all the bubbles through the system and achieve good water flow before the Heat Siphon turns on. You will see it as, FLO, 14, 13, 12, 11, FLO, 9, 8, 7, 6 etc. Modes: (POOL, SPA, AUTO PIC, OFF) 1.2 LED STATUS Lights... -
Page 37: Changing Pool Temperature
No matter what MODE your Player is in, it will not allow your Heat Siphon to run if there are any safety switches tripped or errors. That means there must also be water flow and air above 45°F to 50°F. Switching between any mode is normally not necessary or recommended unless you have a pool/spa combo and are using manual 3 way valves to switch from pool to spa or spill over mode. -
Page 38: Spa Mode
3.4 AUTO-PIC Mode AUTO or AUTO-PIC Mode is a way for the Heat Siphon to decide, on its own, what body of water you are heating (pool or spa) and then heat that body of water to the correct set point (pool set point or spa set point). This is a convenience feature and the goal is to allow you to simply turn your pump off, switch your valves to pool or spa, and turn your pump back on. -

82°F . For example , if the pool set point is 82°F, only a 20°F rise is needed to get to 102°F instead of starting from cold water. In addition, users can't forget to turn off the Heat Siphon when they are done using the spa, since it is always timed to go idle. -
Page 44: Low Refrigerant Pressure (Lo P)
SERVICE CODE - ERRORS REQUIRING USER INTERVENTION - These are Service Codes that turn off the Heat Siphon until either the UP or DOWN arrow key is pressed. Then the Player restarts the unit and the error code goes away. This error is counted and stored. -
Page 45: Low Air Temp. Warning (Lo A)
ALERT CODE - Heat Siphon is equipped with a refrigeration high pressure switch to detect low water flow. • If the pressure goes above a set value it opens and shuts off the Heat Siphon. This switch will auto-re- set at a slightly lower pressure. -

Page 48: Air Temp Sensor Short (Sa S)
SERVICE ERROR - No Pod Service Code means the Heat Siphon is looking for an external hardwired add on Pod (See Accessories - J-POD, T-POD, S-POD) and it is shutting the Heat Siphon down because it has been controlling a pump and no longer can detect or control the pump so to be on the safe side it shuts the heater and POD terminals down and waits for user interaction. -

SPA / HOT TUB Heating Issues Appendix D SPA / HOT TUB Heating Issues WARNING! Water Temperature Safety Failure to heed the following may result in permanent injury or death. Prolonged immersion in water warmer than normal body tempera- ture may cause a condition known as HYPERTHERMIA. The symp- toms of hyperthermia include: unawareness of impending hazard, failure to perceive heat, failure to recognize the need to exit the spa, and unconsciousness. -

Page 70: Spa Temperature Sensor Calibration
As of Player software revision 1.253 (heating only models) and 1.309 (Heat/Cool models) Heat Siphon's DIGITAL Z series Player Controller provides a way to calibrate the spa temperature sensor by increasing the inlet tempera- ture reading to match the actual spa temperature. The temperature may be increased from 1 to 5°F in 1°F steps. -
Page 71: Spa Thermostat Set Points Above 102°F
Based on CPSC Guidelines it appears unnecessary or at least unwise to heat above 102°F,. and even though the UL standard for spa heaters allows a maximum thermostat set point of 104°F , Heat Siphon has chosen to set the default maximum spa set point temperature of 102°F.
