Receiving and storage
Field receiving
Inspect the unit carefully for possible
freight damage. Should any damage
revealed, a report should be submitted
to the carrier for compensation. Check
the unit nameplate data with order
request form data and data on the
freight bill to assure the unit is “as
ordered”.
To minimize loss of transmit damage,
please follow the inspection steps
hereafter one by one before signing on
the freight bill.
1.Inspect each component carefully.
Check the unit and cartons for any
visible scratch or damage.
2.Inspect the unit for any concealed
damage on arrival as soon as possible.
A report should be submitted within
fifteen days. Should any concealed
damage exist, stop unpacking the unit
and keep everything as they are at
the job site. Photos should be taken,
if possible, and evidence should be
provide by the clients on a damaged
unit before arrival.
3.Inform the final carrier of damage
situation by phone or mail. At the
presence of both the carrier and sales
personnel, check procedures should
be performed on to what extent the unit
is damaged.
4.Contact sales representative and ask
for repair. Service the unit only after
signature of the carrier on the damage
situation report.
Note The unit is charged with
adequate refrigerant before ex-factory.
Pressure check should be done on unit
arrival with pressure gauge to assure
leak free during transmit. A service
valve hose is shipped in the unit shell
for this purpose. If no leakage found,
a indication of normal unit, remove the
hose and cap the service valve for seal
purpose, if else, a service should be on
the way.
Field storage
This unit is designed for indoor use.
Erosion due to bad weather will
damage the unit and provide the
opportunity for pollutant’s emergence,
which the indoor air quality will suffer
from when unit placed outdoor. When
outdoor installment is the only option,
protections hereafter should be
provided.
1.Install the unit on or above a dry field
where air flows without obstruction.
2.Waterproof oilcloth should be used to
protection the unit from wind blowing
and rain falling on.
3.Methods should be taken to assure
continuous ventilation around the
unit in case of humidity attachment
on the unit surface. Wet insulation
layer is a perfect place for bacteria,
mould specially to grow, which is
acknowledged as a reason responsible
for odor diffusion and air quality loss.
4.Unit should be placed in a upright
position so as to remain oil in the
compressor.
5.Less than three horizontal units can
be tiled horizontally, which is not an
option for vertical units.
Warning Wet insulation layer
inside the unit is a perfect place for
microbial(mould) growth which is
proven as responsible for indoor
odor diffusion and air quality loss
resulting directly health problem. If
any mould appears in the insulation
layer, remove and change that layer
prior to unit start or severe health
problems will be suffered from.

Hanging unit
Balance the unit weight center for
safety before unit hanging. Refer to
Table 1 and Figure 2 for unit gross
weight and mass distribution.
Warning Field hanging device must
have a safety factor to bear unit weight.
Under capability hanging device
used will cause body hurt or death of
personnel and damage to the unit.

Horizontal unit installation
clearance
Adequate clearance should be spared
for service access. Required service
access for horizontal unit is shown in
Figure 3. A 457mm pass-way space
should be reserved around the unit
for service. For units with supply and
return at the same side, as shown in
Figure 3, a 76mm pass-way at one
side of the unit, other methods should
be taken for thermal expansion valve
maintenance. This configuration
is typical for units installed in a
constrained place, corridor specially.
Vertical unit installation
clearance
Adequate clearance around the unit
must be reserved for convenient
service and fluent ventilation. Minimum
clearance required for vertical unit
service and ventilation is shown in
Figure 4.

Installation
Supply hose connection
Supply opening flange is shipped
with the unit in a box at one side of
the unit for horizontal unit and at the
compressor side for vertical unit.
A closed flexible adaptor is field-
supplied for duct connection in case of
sound diffusion, detailed in Figure 5.
A elbow with viable blade or baffles is
recommended to attenuate noise and
decrease static pressure loss due to
torrent current.
Return hose connection
An adjustable filter frame is field-
installed for horizontal units. For
vertical units, a filter rack is factory-
supplied and shipped with the unit.
A closed flexible adaptor is field-
supplied for duct connection in case of
sound diffusion, as shown in Figure 6.
A elbow with viable blade or baffles is
