refrigeration work can be omitted. The unit operation
can commence immediately after connection to the
power supply, drain piping, ducting and control
system.
The sensible cooling capacity has been significantly
improved through optimized heat exchanger design.
Comfort Heating
The PRH series are designed to provide effective heating
even when the outside temperature is down to 0˚C. The
PRH-L series are designed to provide effective heating
even when the outside temperature is down to -10˚C.In
addition, the twin circuit models, PRH-15,20YA,
PRH-15,20YA-L are provided with control features that
prevents both refrigeration circuits defrosting at the same
time. This ensures constant comfort conditions during
defrost and varying loads.
Low Ambient Cooling
In applications with relatively high internal loads,
there may be a requirement for all series to operate
on cooling at low ambient conditions. An optional
accessory is available to maintain the refrigeration
circuit in balance at outdoor temperatures as low as
0˚C (PRH only).In case of PR,PRH-L is -5˚C.

INSTALLATION
All series of air conditioners are designed for outdoor installations and are to be placed on a slab or
rooftop, however if the air conditioner is to be installed in a plant room application, please contact your
equipment supplier prior to installation.
Access for both service and installation must be provided to the compressors, control wiring and fans as
shown below.
1.Clearances
(1) Care must be taken to prevent recirculation of
the condenser air. To stabilize compressor
condensing pressures it is recommended that
wherever possible the condenser air inlet side
be faced away from prevailing winds.
(2) For rooftop installation, the type of mounting
base depends on the roof construction. A builtup roof may not support the weight of the unit
and so it may be necessary to support the unit
by adding structural members below it.
(3) The units are equipped with hoisting
plates for rigging and hoisting of the unit.
The hoisting plates are located in the base
of the unit.
When hoisting the unit with a crane,
spreader bars must be used to prevent
damage to side panels by the supporting
cables.

3.Duct Work
(1) All series units are equipped with horizontal
supply and return air openings. Duct connection to
the unit should be made with duct flanges and
secured directly to the air openings with flexible
duct connectors to avoid normal noise transmission.

(2) For vertical air supply, a field supply plenum should
be used.
The figure below shows the recommended method
for duct connection.
(3) To prevent air leakage, all duct seams should be
taped.
Ducts run in air spaces that are not air-conditioned
must be insulated and provided with a vapor barrier.
Ducts exposed to the outside must be
weatherproofed. For quiet operation, we
recommend that the insulation on the supply duct
be placed inside, lining the duct.

(4) Where ducts from the outside enter a building, the
duct openings in the building should be sealed with
weather stripping to prevent rain, duct, sand,etc.
from entering the building.
(5) Correctly sized filters must be fitted and there is no
provision within the unit, however the filters may be
installed in the return air.
(2) The drain pipe must be provided with a trap on the
outside of the unit and also installed at an incline for
proper drainage, as shown below.
(3) To prevent condensate formation and leakage,
provide the drain pipe with insulation to safeguard
against sweating.
(4) Upon completion of the piping work, check that there
is no leakage and that the water drains off properly.
