Typical piping diagram (NK)
Figuare 19. Typical piping diagram
1. Work outside the area surrounded by this line shall have to be
executed at the expense of the owner.
2. Refer to the external dimensions diagrams and specification tables for
pipe connections and diameters.
3. Standard supply steam press. is 784kPa gauge. A reducing valve and
safety valve which blows at 980 kPa gauge should be located near the
machine as in above diagram if the supply pressure is higher than
784 kPa gauge.
A pipe should be extended from this safety valve to release excess
steam outdoor.
4. Even if a reducing valve is not required, a strainer, pressure gauge and
drain trap should be provided for each machine near the steam inlet.
5. The back pressure in the steam drain line should be limited to less
than 49kPa gauge.
6. Determine the locations of the chilled water pumps and cooling water
pumps in due consideration of the pump's hydrostatic head and lift.
The machine should not be subject to a pressure larger than 784 kPa
gauge at any water headers.
7. Concerning the temperature control of cooling water, refer to
"control method of cooling water temperature".
8. Provide a thermometer and a pressure gauge at the outlet and
inlet of cooling water and chilled water.
9. Provide an air vent in each of the chilled and cooling water line at
a point higher than the headers for chilled water and cooling water.
10. Lay pipe from the cover of the evaporator and absorber to the
drain ditch.
11. Provide a bleeder in the cooling water line for control of water
quality.
12. Be sure to provide the shut-off valve to prevent the steam flow into
the chiller during shut-down. and in case that two or more chillers
are installed, provide the automatic shut-off valve.
(The terminals sending open / close signal to steam shut-off valve
are furnished in control panel of the chiller.)
13. Be sure to design the location of cooling tower to prevent
contaminatin of cooling water by exhaust gas from flues.

Rupture disk mounting
Mounting instructions of rupture disk1. Apply the teflon paste (Part code:814-2-3701-002-00)
to both sides of gasket slightly as shown in fig. 2In order to avoid leakage, don't apply too much teflon paste.
2. The gasket (Part code:814-2-2101-678-00-0 Should be used asindicated in FIG, 3.
3. Attach the upper flange exactly parallel to the lower flange.
4. A torque wrench should be used for tightening bolts equally and theappropriate torque is shown in fig.3 in disregard of the torquetable in the manufacture's installation instructions.Read the Manufacture's installation instructions before assembling.
5. Tighten up the bolts by a torque wrench in a periodical maintenance.6. The used gasket should not be applied again.7. Leak test should be conducted by bubble test.

Precautions for installation (NK)
1. Please keep local regulation at installation.
2. The chiller shall be installed in indoor.
3. Please install the chiller on the floor of heavy duty construction.
4. Please keep service maintenance space as shown dimensions drawing.5. Don´t install at many dust area.6. If necessary, please attach antivibrator.7. Please install control panel to avoid the direct rays of the sun. If the control panel is exposed to the direct rays of the sun,
it is difficult to show the display.8. Don´t install near exhaust gas port, deodorizer´s port and ventilation port.9. Please use the shackle, when the chiller is lift by wire.
In this case, please insert the shackle to the hole of the lower shell.10. Don´t fall down side-ways.11. Please keep delivery space for smooth installation.12. Take care the impact or fallen.13.
