2Principle!of!heat!pumps!!
!
A!heat!pump!is!a!device!in!which!a!refrigerant!continuously!changes!phase!from!gas!to!liquid,!
changing!temperature!at!the!same!time.!In!the!cold!liquid!state!it!absorbs!energy!from!the!
atmosphere!as!it!evaporates!to!gas.!More!energy!is!added!at!the!compressor!as!the!warm!gas!is!
compressed!to!a!high!pressure!hot!gas.!The!combined!energy!is!released!into!your!house!when!
the!hot!gas!condenses!back!to!liquid.!The!cool!liquid!is!expanded!back!to!a!low!pressure!cold!
liquid!and!the!process!is!continuously!repeated.!
The!advantage!of!a!heat!pump!is!that!it!moves!more!heat!energy!through!the!vapour?
compression!cycle!described!above!than!the!electricity!it!consumes,!providing!very!high!
effective!efficiency.!The!Coefficient!of!Performance!(COP)!of!a!heat!pump!is!the!ratio!of!the!
total!energy!delivered!over!the!amount!of!energy!consumed!by!the!compressor!and!is!typically!
in!the!range!of!3!to!4.!

Do!not!climb!on!the!unit!or!try!to!move!it!after!it!
has!been!installed.!
Do!not!allow!children!to!play!on!or!around!the!
unit.!
Do!not!place!any!items!into!ventilation!openings!
on!the!side!of!the!unit.!Doing!so!could!damage!
equipment!or!result!in!severe!electrical!shock.!
If!you!detect!any!abnormal!odour!from!the!unit!
or!the!smell!of!burning!turn!off!the!power!and!
switch!off!power!at!the!breaker.!
Do!not!pull!on!the!power!cables!or!place!these!
under!tension.!
Do!not!clean!the!appliance!with!water!as!this!can!
damage!the!insulation!on!the!hot!water!tank.!
Do!not!place!any!objects!in!front!of!the!air!vents!
on!the!side!of!the!unit!that!may!block!airflow!as!
this!can!cause!internal!electronics!to!over!heat.!
Avoid!touching!power!cables!or!any!electrical!
connections!with!wet!hands!as!there!is!a!risk!of!
electric!shock.!
Failure!to!turn!off!all!power!connections!to!the!unit!(system!power!and!electric!backup!heater)!at!the!
disconnect!or!breaker!before!installing!or!servicing!the!system!can!result!in!severe!personal!injury!or!
death,!and!can!result!in!damage!to!the!equipment.!
Never!make!any!changes!to!the!control!parameters!unless!you!are!fully!aware!of!how!these!will!affect!
the!operation!of!the!system!and!know!that!those!changes!will!not!increase!the!risk!of!injury!to!people!
or!cause!damage!to!the!unit!or!any!associated!heating!equipment.!
Only!a!certified!refrigeration!technician!familiar!with!the!use!of!R410a!refrigerant!should!make!any!
adjustments!in!the!refrigerant!levels!in!the!system.!
