Very Important!
1.
The standard target fluid temperature is limited to a range of 40° F to 80° F on all Delta Star Heat pumps. Without
special factory installed equipment, possible damage to the unit can occur when attempting to access fluid
temperatures outside this range. Aqua Logic, Inc.’s warranty does not apply to application temperatures under
40°F or above 80° F without special factory modifications.
Compressor crankcase heater must installed when ambient air temperature is 60°F and below.
2.
Water going to the heat pump should be protected by filters to keep debris from collecting in the evaporator and
condenser shells. Clogged shells lead to heat exchange problems and will void the warranty.
3.
Improperly installed or out of adjustment rapid sand filters can put sand into the stream of water flowing into the
heat pump. This condition is similar to “sand blasting” and may abrade holes in plumbing lines or the evaporator
and condenser. Conditions like these would void the Aqua Logic, Inc. warranty.
40° F to 80° F Pool Temperature Applications
Wetted parts contain titanium, PVC plastic, rubber, and polymer. These materials are non-reactive with fresh and
salt water. You must consult with Aqua Logic, Inc. if any other fluids are to be pumped through the heat pump.
If humid or wet conditions exist where heat pump is to be located, care must be taken to prevent water from
getting on electrical components.
4.
On some heat pump models, allow only qualified licensed personnel to supply electric power to heat pump.
Installation must be done in accordance with local and national electrical code. Delta Star heat pumps need a
fusible disconnect installed within five feet. The heat pump needs a dedicated power supply.
Do not
share the
power feed with any other peripheral devices such as pumps, ultraviolet light sterilizers, or filters. Install an
interlock device such as a water flow switch which prevents the heat pump from energizing without the pump
being on.
5.
Double check electrical specifications on unit’s electrical access cover plate making sure of voltage, amperage,
phase, and cps before energizing. (
Do not
remove any covers with electrical power on.)
6.
Fluid must flow through the heat pump at all times.
See heat pump specification sheet or product label for
minimum and maximum flow rates. Flow rates less than specification may result in evaporator freeze-up and
cracking of the evaporator shells. Also over heating of the heat pump can occur due to lack of water flow to the
condenser. Aqua Logic Inc. does not warranty evaporator shells operating under low flow conditions and
compressor burn outs due to overheating.
7.
Incoming water pressure to the evaporator must not exceed 50 psi and condenser must not exceed 100 psi. Over
pressuring the evaporator and condenser may cause damage to the shells, which is
not
covered under warranty.
