BEFORE OPERATION
Do not charge OXYGEN, ACETYLENE, or other flammable
and poisonous gases into the refrigerant because an explosion
can occur. It is recommended that oxygen free nitrogen be
charged for these types of tests cycle when performing a
leakage test or an airtightness test. These types of gases are
extremely dangerous.
Insulate the unions and flare-nuts at the piping connection part
completely.
Insulate the liquid piping completely to avoid a decrease of
performance; if not, it will cause sweating on the surface of the
pipe.
Charge refrigerant correctly. Overcharging or insufficient
charging could cause a compressor failure.
Check for refrigerant leakage in detail. If a large refrigerant
leakage occurred, it would cause difficulty with breathing or
harmful gases would occur if a fire were being used in the
room.
If the flare nut is tightened too hard, the flare nut may crack
after a long time and cause refrigerant leakage.
The heat pump indoor unit is suitable for the floor mounted
condition (h
= 0.6m) for most installations.

4. BEFORE OPERATION
4.1 GENERAL NOTES
4.1.1 Selection of the installation location
The indoor unit must be installed following these basic
requirements:
● The indoor unit is intended to be installed in an indoor
place and for ambient temperatures ranging 5~30°C.
The ambient temperature around the indoor unit must
be higher than 5°C to prevent water from freezing.
● Make sure that selected floor is flat, strong enough for
supporting the indoor unit weight.
● Be sure to maintain the recommended servicing space
for future unit servicing and guarantee enough air
circulation around the unit (See "5.1 Service space"
section).
● Take into account that shut-off valve with filter (factory
supplied) must be installed at the indoor unit inlet
connections.
● Keep water draining provisions. The safety valve is
provided with a drain pipe which are located at the drain
pan of the unit.
● Protect the indoor unit against the entry of small
animals (like rats) which could making contact with the
wires, the drain pipe, electrical parts and may damage
unprotected parts, and at the worst, a fire will occur.
● Install it in a no-frost environment.
● Do not install the indoor unit in a location with very high
humidity.
● Do not install the indoor unit where electromagnetic
waves are directly radiated to the electrical box.
● Install the unit in a place where in case of water
leakage, any damage to the installation space cannot
be produced.
● Install noise filter when the power supply emits harmful
noises.
● To avoid fire or explosion, do not install the unit in
flammable environment.
● The air to water heat pump must be installed by a
service technician. The installation must comply with
local and European regulations.
● Try to avoid to put any objects or tools above the indoor
unit.
4.1.2 Unpacking
All units are packed by a wooden pallet and carton assembly.
Firstly to unpack it, place the unit on the assembly area as
close as possible to its final installation location, to avoid
damages in transport. Two persons are required.
1 Cut the strapping bands and remove the adhesive tapes.
2 Remove the carton assembly and then the plastic bag
around the unit.
