9) The pipeline diameter of cooling water tower and circulating pump should be
no less than that of the connection tube of condenser (the installation of
ingress and egress pipeline system should comply with the assembly line
diagram). When perform long distance transportation the heavy caliber water
pipe should be used for connecting the cooling water.
10) The automatic exhaust steam valve should be installed in the topmost place
of the refrigerated water circulation loop system, and the discharge valve
should be installed at the lowest place.
11) When the water quality is poor and the ambient environment of
cooling-water tower is inclement, the circulation loop system of cooling water
and refrigerated water should install filtering apparatuses and clean up
regularly.
12) Complete the installation of pipeline system and carry out leakage test, the
refrigerated water circulation loop should be covered by thermal insulation
layer to avoid the dissipation of quantity of cool and the water drop from the
pipelines.
13) This series model due to the water cooled in the cooling tank, the user must
supply the chiller with enough cool water according to the manual requires
while do system installation, or else the model would appear as high pressure
over high, and cooling capacity getting down.
The power connection of the chiller should be carried out by the
professional electrician! The electric circuit of the chiller should not be
changed without the permission from our company.
3.2 Water Pipe Installation
1) Keep the inlet/outlet pipe of the unit and its valves insulative to avoid
refrigeration lost and dewing.
2) In order to keep enough water remain within evaporator or condenser pipe
system, place water flow valve at the water outlet sides of the evaporator and
condenser. It is coordinate controlled with compressor so to avoid the internal
freezing, over low pressure, or bad oil return within system due to water
shortage in the evaporator. In the same way to avoid the happening of high
pressure protection due to over high condensing pressure.
3) For more than one heat exchanger and one chiller shunt together to work,
