l Prolonged immersion in water warmer than normal body temperature may cause a condition known as
Hyperthermia. The symptoms of Hyperthermia include unawareness of impending hazard, failure to perceive
heat, failure to recognize the need to exit the spa, and unconsciousness. The use of alcohol, drugs, or medication
can greatly increase the risk of fatal Hyperthermia. In addition, persons having an adverse medical history, or
pregnant women, should consult a physician before using a hot tub or spa. Children and the extreme elderly
should be supervised by a responsible adult.
l Prolonged immersion in water colder than normal body temperature may cause a condition known as
Hypothermia. The symptoms of Hypothermia include shivering (although as hypothermia worsens, shivering
stops), clumsiness or lack of coordination, slurred speech or mumbling, confusion and poor decision-making,
drowsiness or low energy, lack of concern about personal welfare, progressive loss of consciousness, weak
pulse and slow or shallow breathing. In addition, persons having an adverse medical history, or pregnant
women, should consult a physician before immersing in a cold body of water. Children and the extreme elderly
should be supervised by a responsible adult.

3.2 Positioning Equipment
Controlling Irrigation and Rainwater Runoff
l Irrigation water may damage heat pump components. Have irrigation water directed away from the heat pump.
l The 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.
Planning for Condensation
The heat pump can produce a large amount of water in the form of condensation. The amount of water
depends on air temperature and humidity.
l Install the heat pump with enough height to allow for water drainage.
l Plan for water drainage disposal as needed.
Mounting Pad Requirements
l Build the heat pump pad out of concrete or another code-approved material.
l
Confirm the pad can support the weight of the heat pump. See "Weights" on page 40.
l Elevate the pad enough to allow for drainage.
l Make sure the pad is flat and level.
l Have the pad extend at least 6 inches from the heat pump base in all directions.
l Do not install the heat pump on soil or grass.
l Do not allow the heat pump base to touch the buildings foundation.
l Do not place the heat pump directly on a concrete floor inside a building. This can cause noisy equipment
vibration. Install vibration dampeners between the heat pump base and floor.
l Equipment pad must meet all requirements of authorities having code-related jurisdiction.
Anchoring to Pad
l Follow all applicable local, state, and national requirements regarding wind load anchoring.
l The shipping brackets used to tie the heat pump to the pallet are approved mounting (hurricane) brackets. They
can be used to anchor the heat pump to the pad.
l
If needed, contact AquaCal®Customer Support to obtain the correct anchoring kit information. Please have the
heat pump model number and serial number when requesting support. See "Identifying Model Specifications" on
page 39.
3.3 Plumbing
3.3.a Clearances
l Proper air circulation is required for the heat pump to operate efficiently. Avoid placing objects near or on top of
the heat pump. This includes shrubbery and lawn furniture. These objects will also hinder maintenance access.
l Avoid storing chemical containers near the heat pump. The chemicals can cause equipment damage.

If water flow through the heat pump is reduced, performance will suffer and internal safety devices may
deactivate the heat pump with error codes HP and HP5, or (if equipped) an LP and LP5.
l Operate water filtration devices per manufacturer's specifications. Dirty filters can cause reduced water flow to the
heat pump. 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
l Keep baskets free of debris. Similar to a dirty filter, large volumes of debris in the pump and skimmer baskets can
reduce water flow.
l Check 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.
l The maximum static (or operating pressure) is 50 pounds-per-square-inch (PSI). These specifications relate to the
heat pump only. Code-specified whole system turnover rates must be satisfied.
3.3.c 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.
l Installed Temperature / Pressure probes and ports are required to perform the following procedures.
l
This adjustment procedure is to be completed with the unit in HEA mode only; ACH and COO discharge
temperatures are not shown.
PLEASE NOTE -
Temperature / Pressure ports are required for all commercial applications.
They are strongly recommended (but not required) for residential installations.
