CONSIDERATIONS
The precautions listed here are divided into the following two types.
Both cover very important topics, so be sure to follow them carefully.
Danger
■
Before touching electric terminal parts, turn off power switch.
■
When service panels are removed, live parts can be easily
touched by accident.
Never leave the unit unattended during installation or servicing
when the service panel is removed.
■
Do not touch water pipes during and immediately after operation
as the pipes may be hot. Your hand may suffer burns. To avoid
injury, give the piping time to return to normal temperature or be
sure to wear proper gloves.
■
Do not touch any switch with wet fingers. Touching a switch with
wet fingers can cause electrical shock.
■
Before touching electrical parts, turn off all applicable power
supply.
Warning
■
Tear apart and throw away plastic packaging bags so that
children will not play with them.
Children playing with plastic bags face danger of death by
suffocation.
■
Safely dispose of packing materials. Packing materials, such as
nails and other metal or wooden parts, may cause stabs or other
injuries.
■
Never directly touch any accidental leaking refrigerant. This
could result in severe wounds caused by frostbite.
■
Do not touch the refrigerant pipes during and immediately after
operation as the refrigerant pipes may be hot or cold, depending
on the condition of the refrigerant flowing through the refrigerant
piping, compressor, and other refrigerant cycle parts. Your
hands may suffer burns or frostbite if you touch the refrigerant
pipes. To avoid injury, give the pipes time to return to normal
temperature or, if you must touch them, be sure to wear proper
gloves.
■
Do not touch the internal parts (pump, backup heater, etc.)
during and immediately after operation.
Your hands may suffer burns if you touch the internal parts. To
avoid injury, give the internal parts time to return to normal
temperature or, if you must touch them, be sure to wear proper
gloves.

Installation of the ERHQ or ERLQ heat pump outdoor
