4.1.b Water Flow Rates
Maintain water flow rates as indicated. Please note, these specifications relate to the chiller only. Codespecified whole system turnover rates must be satisfied.
l
CAUTION - Failure to heed the following may result in equipment damage.
Water flow exceeding maximum flow rate may damage heat exchanger; such damage will not be covered under the equipment warranty
MODEL
FLOW RATES
HEAT EXCHANGER TYPE
MINIMUM MAXIMUM
TC500 Titanium Tube-in-Tube 20 GPM 45 GPM
TC1000 Titanium ThermoLink ® 30 GPM 70 GPM
If water flow through the chiller is reduced, performance will suffer and internal safety devices may deactivate the chiller with error codes LP or LP5.
l l l
Operate water filtration devices per manufacturer's specifications. Dirty filters can cause reduced water flow to the chiller. An increase of 7-10 psi higher than the clean filter pressure typically reduces flow rates. This requires the filter to be cleaned or back-washed
Keep baskets free of debris. Similar to a dirty filter, large volumes of debris in the pump and skimmer baskets can reduce water flow.
Check for improper valve settings. A partially closed valve after the filter, or a full-open bypass around the chiller, will cause insufficient water flow through the chiller.
Page - 7
l
The maximum static (or operating pressure) is 50 pounds-per-square-inch (PSI) unless a special "high-pressure" unit has been ordered. These specifications relate to the chiller only. Code-specified whole system turnover rates must be satisfied.
4.1.c Irrigation and Storm Run-Off l l
Corrosive irrigation water may damage chiller components. Have irrigation water directed away from the chiller.
The chiller will withstand normal rainfall. Do not allow a roof slope to direct rainwater onto the chiller. Have a gutter installed on the roof edge to direct this water away from the chiller. Or install the chiller in another location.
4.1.d Clearances l l
Proper air circulation is required for the chiller to operate efficiently. Avoid placing objects near or on top of the chiller. This includes shrubbery and lawn furniture. These objects will also hinder maintenance access.
Avoid storing chemical containers near the heat pump. The chemicals can cause equipment damage.

4.4 Winterizing l
WARNING - Failure to heed the following may result in injury or death.
Deactivate all electrical power to chiller before performing hard freeze procedures.
l l
CAUTION - Failure to heed the following may result in equipment damage.
Failure to winterize chiller may result in serious equipment damage. Freeze damage is not covered under the chiller warranty.
While the plumbing connections are in the winterized condition (not fully tightened), it is imperative the pool and spa water not be circulated through the chiller. Loss of water through loose plumbing connections may result in damage to circulating pump, pool and spa structures, and other equipment.
Light Freeze Conditions
There are two freeze conditions requiring chiller attention. A light freeze is when the ambient air temperature falls below 32 degrees Fahrenheit for less than 8 hours. Typically during light freeze conditions circulating (moving) water will not freeze. Override time clocks and allow filtration system to run continuously during light freeze conditions.
Hard Freeze Conditions
A hard freeze is when the ambient air temperature falls below 32 degrees Fahrenheit for more than 8 hours.
In areas where this condition is prevalent and sustained, the chiller MUST be winterized for hard freeze conditions. Follow the correct procedure depending on the type of heat exchanger found in the chiller.
Identify Exchanger:
1. Deactivate all electrical power to chiller.
2. Deactivate filter pump.
3. Remove front access panel.
4. Identify chiller exchanger from illustrations in this section. Then follow procedure for that chiller's exchanger.

See "Automatic Sequencing Controller" on page 18.
3. If a fault occurs immediately when the compressor starts, a qualified technician should evaluate the system.
Chiller Won’t Shut Off
Chiller Is Running, Not Cooling (Reversing Models)
1. Confirm the chiller mode is set to COO operating mode.
2. Confirm the thermostat is set below the current water temperature.
3. Confirm chiller is transferring heat out of the water.
l
Measure the temperature of air discharge coming out of chiller fan. If discharge air is between 8° to 10° warmer than outside ambient air (not coming out of chiller), then the chiller is moving heat out of the water.
5. Confirm valves are correctly positioned to cool the correct body of water (either the pool or the spa). If cooling a spa that overflows into a pool, confirm the spa is isolated when being cooled (not flowing into the pool).
6. Confirm that filter pump has a sufficient run-time. The chiller will not run (or cool the water) without water flow.
See "Initial Cooling Recommendations" on page 18.
Page - 15
Water Coming From Chiller
The water may be normal condensation produced as a by-product of the chiller's refrigeration process. The chiller can produce 8 to 10 gallons of condensation per day depending on the humidity of the ambient air.
Determine if the water is condensation or a possible leak.
1. If using chlorine or bromine as a pool / spa sanitizer, use a test strip in the water at chiller to determine if sanitizer is present. If sanitizer is present, a leak may exist.
2. Deactivate chiller, leaving the filter pump on. After several hours, determine if water is still coming from the chiller.
3. If the issue reoccurs, please contact the installing dealer. Or contact AquaCal ® for a service partner in your area.
