1.1 Positioning Equipment
Controlling Irrigation and Rainwater Runoff
lIrrigation water may damage heat pump components. Direct irrigation water away from the heat pump.
lThe heat pump will withstand normal rainfall. Do not allow a roof slope to direct rainwater onto the heat pump.
Have a gutter installed on the roof edge to direct this water away from the heat pump. Or install the heat pump in
another location.
Mounting Pad Requirements
lThe heat pump's base must be installed on a flat and level surface that completely supports the entire base.
lBuild the heat pump pad out of concrete or other code-approved material.
lConfirm the pad can support the weight of the heat pump. See "Weights" on page75.
lElevate the pad enough to allow for drainage.
lMake sure the pad is flat and level.
lHave the pad support the entire heat pump base in all directions.
lDo not install the heat pump on soil or grass.
lDo not allow the heat pump base to touch the building's foundation.
lDo not place the heat pump directly on a concrete floor. This can cause noise to be transmitted to an occupied
space. If necessary install vibration dampers between the heat pump base and floor.
lEquipment pad must meet all requirements of authorities having code-related jurisdiction.
Anchoring to Pad
lFollow all applicable local, state, and national requirements regarding wind load anchoring.
lThe shipping brackets used to secure the heat pump to the pallet are approved mounting (hurricane) brackets.
They should be used to anchor the heat pump to the pad.
lIf needed, contact AquaCal®to obtain anchoring kit information. Please have the heat pump model number and
serial number when requesting support. See "Identifying Model Specifications" on page74.
1.2 Clearances
lLocate the heat pump at least 24 inches (61 cm) away from the wall. And provide a minimum 24 inches (61 cm)
between heat pumps. This will allow for rear plumbing access and electrical connections.
lDo not stack heat pumps on top of each other. Use approved racks when stacking equipment.
lOnly rack equipment two units high.
lEquipment rack must meet all requirements of authorities having code-related jurisdiction.
lAvoid storing chemical containers near the heat pump. The chemicals can cause equipment damage.
lAvoid placing objects near or on top of the heat pump. This includes shrubbery and lawn furniture. These objects

1.4 Plumbing
1.4.a Plumbing Requirements
NOTICE
Failure to heed the following may result in damage to equipment.
lDo not use glue on the threaded portion of the equipment’s unions. A glued-in-place union will prevent the
equipment from being properly winterized.
lThe heat pump must receive water flow within the specified minimum ranges under worst-case conditions such as
a fouled water filter.
lFailure to provide clean filtered water to the heat pump can void the product warranty.
lWater flow exceeding maximum flow rates will negatively affect the total pool filtration performance and may
damage the heat pump. This will not be covered under the equipment warranty. See "Water Flow Rates" on
page14.
lUsing open saltwater applications as the heat pumps source water is not recommended.
lSaltwater can promote the growth of crustaceans, which can clog a heat pump’s heat exchanger. These types of
applications are highly problematic and require additional maintenance.
lIf a saltwater source is unavoidable, install an external plate heat exchanger to protect the heat pump from
fouling. Please note – Saltwater wells do not require an external plate heat exchanger.
lA safety-enhancing "Over Temperature Alarm"kit is strongly recommended for all spa applications. See "Over
Temperature Alarm Kit" on page77.

PLEASE NOTE -
If minimum flow rates are not met, heat pump performance is reduced and performance will
suffer. Internal safety devices may deactivate the heat pump with the following errors:
lHIGH PRESSURE FAULT
lHP5 SYSTEM LOCKOUT
lLOW PRESSURE FAULT
lLP5 SYSTEM LOCKOUT
lOperate water filtration devices per manufacturer's specifications. Dirty filters can cause a reduction of water flow
to the heat pump. An increase of 7-10 psi (48 to 69 kPa) higher than the clean filter pressure typically reduces
flow rates. This requires the filter to be cleaned or back-washed.
lKeep baskets free of debris. A large quantity of debris in the pump and skimmer baskets can reduce water flow.
lCheck for improper valve settings. A partially closed valve after the filter, or a full-open bypass around the heat
pump, will cause insufficient water flow through the heat pump.
lThe maximum static pressure (or operating pressure) is 50 psi (345 kPa) unless a special "high-pressure" unit has
been ordered. These specifications relate to the heat pump only.
lCode-specified whole system turnover rates must be satisfied.
1.4.g Adjusting Water Flow Using ΔT (Delta-T)
The Delta-T is the temperature difference between the water temperatures entering and leaving the heat pump.
The equipment can be fine-tuned for maximum performance by balancing water flow rates to maintain an
ideal ∆T.
The adjustment procedure must be completed with the unit in heating mode.
PLEASE NOTE -
nSee "Temperature Port Kit (# STK0096)" on page78.
1. Adjust the thermostat to its lowest setting with the unit in heating mode.
2. Deactivate the water filtration pump.

3. Confirm that the filters leading to the heat pump are clean.
4. Adjust the valves controlling water headed towards the heat pump to the half-open position.
5. Adjust the valves controlling water leading away from the heat pump to a fully open position.
6. Activate the pool water filtration pump.
7. Slowly raise the thermostat temperature until the heat pump activates.
lThe source-water filtration pump will cycle on first.
lAfter a three-minute delay, the heat pump's compressor will start.
8. With the heat pump running, confirm the source-side water filtration pump is operating properly with adequate
flow and no short cycling.
9. Wait for water temperatures to stabilize (approximately 5 minutes).
10. Open the temperatures differences screen in the Geothermal Menus. See "Geothermal Menus" on the facing
page.
12. Adjust valves in the following order using the temperature
chart provided.
a. Adjust the source-side valve on the heat pump outlet
until the correct temperature differential is achieved.
b. Adjust the pool-side valve that controls water exiting the
heat pump until the correct temperature differential is
achieved.
c. Wait for water temperatures to stabilize. Then check the source-side temperature again. Re-adjust the valve as
needed.
13. Mark valves at these positions for future reference.
