2.2 Installaon Guideline (Outdoor Clearance)
2.2.1 Space for installaon of outdoor units
One single outdoor unit can be installed in one place, mulple outdoor units can be installed in one large
place in order, refer to the followings:
• The required installaon space shown in the gure above takes the presumpon that a unit provides
refrigeraon at an outdoor temperature of 35°C. If the outdoor temperature exceeds 35°C, the heang
load is higher, and all outdoor units will be running over capacity. The space needed will be larger than
the one shown in the gure.
• If an outdoor unit has a wall in the front and back respecvely, with the wall in the front not higher than
1500 mm and the back wall not higher than 500 mm. Please reserve at least 500 mm installaon space in
front and at least 300 mm at back.
• If an outdoor unit has a wall over 1500 mm in front, reserve at least (500+h2/2) mm installaon space
in front.
• If an outdoor unit has a wall over 500 mm the back (air sucon side), reserve at least (300+h1/2) mm
installaon space in front.
• If the distance between the top of an outdoor unit and barrier is lesser than 1500 mm, please install an
air deector will be required on the air outlet side (plenum) to prevent return air short circuit.
• If a barrier exists over the top of an outdoor unit. It is required that the front, back, le, and right sides of
the outdoor unit to be open in principle.

2.2.2 Handling outdoor units
Please refer to the followings to conduct moving of units; use 4 supporng point to move units.
Note:
• Outdoor unit transportaon shall be very careful;
• Use special rope to e the units for transportaon;
• Do not touch the ns of units to avoid hurt of hand;
• Keep the plasc bag from away the child;
• Please select the appropriate ropes according to the weight of units.

The ‘equivalent length’ is the conversion length including the elbow and other parts of the tube aer loss of
pressure. The formula is as follows:
Equivalent length = actual length of pipe + (number of elbows x equivalent length of various elbows)
The equivalent length of each bifurcaon/refnet (branch) is 0.5m, whereas the equivalent length of the
elbows is as shown in the table below:

Note:
The equivalent length of elbow in the table above aims to full installaon standards: the pipe bending radius of curvature is R ≥ 3.5D (D for the pipe diameter),
about ≥ 3/4 of the original diameter before the pipe bending deformaon. If the elbow bending radius does not meet the above installaon standards, the
equivalent length is to be calculated separately (the smaller the bending radius , the longer the equivalent length).
When the equivalent length of all piping is equal to or more than 90 m, the diameter of the main pipe (from the outdoor unit to the rst branch pipe) must be
increased. For example, when the equivalent length of the 10 HP outdoor unit exceeds 90 m, the diameter of the main pipe should be changed from 22.23 mm
to 25.4 mm. When the diameter of the main pipe is increased, the eecve equivalent length must be recalculated. When calculang the extent of performance
degradaon due to the length of the pipe, the pipe length should be...
...calculated according to the eecve equivalent length.
Eecve equivalent length = equivalent length of main pipe × 0.5 + equivalent length aer branching (when the diameter of the main pipe is increased)
The equivalent length of the rst branch pipe to the furthest piping secon is ≤40m. However, when all following condions have been sased, the allowable
length can be extended to 90m.

The diameter of the piping between the rst and the last
bifurcaon/refnet (branch) assembly needs to be increased.
(Please make necessary adjustments on-site) If the piping
diameter is the same as that of the main piping, it does not
need to be increased.

Calculang the addional amount of refrigerant required
1. The copper pipe specicaons and necessary refrigerant amount are as shown in the table below:
Pipe diameter φ22.23 φ19.05 φ15.88 φ12.70 φ9.52 φ6.35
Addional R410A refrigerant needed 370g/m 260g/m 180g/m 120g/m 54g/m 22g/m
2. The addional amount of refrigerant charge needed can be calculated according to the length and
thickness of the refrigerant pipes. The formula is as follows:
Addional refrigerant charge (g) = Total length of φ22.23 copper pipe (m) x 370g/m + Total length of
φ19.05 copper pipe (m) x 260g/m + Total length of φ15.88 copper pipe (m) x 180g/m + Total length of
φ12.70 copper pipe (m) x 120g/m + Total length of φ9.52 copper pipe (m) x 54g/m + Total length of
φ6.35 copper pipe (m) x 22g/m
(3) If the denominaon of the result is less than 0.1kg, carry it forward to the nearest 0.1kg;
for example: If the result is 28.62kg, the nal amount needed should be 28.7kg.
Note:
New fan units already come equipped with 10m main pipe’s worth of refrigerant, so when calculang the
refrigerant amount, reduce main pipe by 10m. The above formula is for reference purposes only; the actual
amount needed can be adjusted on-site.

3. The noise level is tested in the incomplete anechoic lab under the standard refrigeraon condion and got from the value, that from a point is half of the unit
height plus I meter in front of the unit. The real noise value in operaon may be a lile higher than the tested value due to the inuence of the actual
environment;
