Notice the position of connection pipe, do not
connect inlet and outlet pipe reversely.
It is necessary to fix the gauze water filter in
system (40-60 mesh recommended).
Please check and ensure water filter in inlet
pipe to be set near unit side.
Please select the water pipe according to local
or national regulation, besides, the size of water
pipe should not be less than that of pipe joint on unit.
Insulating water inlet and oulet pipe to avoid
condensate water and prevent water from freezing.
Regularly clean water filer according to clogging
degree of that.
Discharging water in heat exchanger and pipe is
suggested throughout the long duration of stoppage
in winter to prevent water from freezing.
Please check and clear unit and accessories in
water system thoroughly before initial startup after
long stoppage.

Before installation, flush all waterpipes thoroughly
to ensure no foreign material in that. Be careful
not to flush any foreign material into plate heat
exchanger;
It is necessary to set a water flow switch on heat
exchanger water outlet to realize stop protection.
Water flow switch should be connected to terminal
TB3 on PCB with shielded cable. Adjust setting
value of switch properly according to rated water
flow;
There must be extra bracerbut not just unit to
support pipe and pipe joint;
Connection pipe and pipe jointon heat exchanger
should be removed easily to make operation and
clean work more convenient;
It is necessary to install sluice valves on water
inlet and outlet of unit to cut off the water flow in
heat exchanger, so that there is no impact on the
usage of other units during maintenancework;
Heat exchanger and connection pipeshould be
connected with flexible joint in order to lower
vibration spread and avoid piping crack;
For easy inspection, thermometers andpressure
gauges should be settled onwater inlet and outlet.
(Units are not equipped with thermometer and
pressure gauge);
Drainage joints should be seton lower points in
water system, so as to discharge water in
evaporator and system thoroughly. All higher
points should be installed with air exhaust valve
in order to exhaust airin pipe. No need to insulate
air exhaust valve and drainage joint for easy
maintenance;
Insulate all water pipes that have possibility to be
iced up. Water pipe can be packed togetherwith
an auxiliary heater band inorder to avoid frost
crack. The heater power source should be
equipped with individual fuse;
Terminals of water flowswitch should be placed
in proper position for easy wiring;
The direction arrow marked onwater flow switch
should be parallel to the direction of water flow,
target paddle should be perpendicular to
direction of water flow;
Water flow switch must be installed in straight
pipe-line and at least 5 times as long as pipe
diameter for straight pipes should be retained
on two terminals of water flow switch;
It can be fixed in horizontal pipe-line or vertical
pipe in which water flows upward, but not vertical
pipe in which water flows downward;
It needs to be interlocked with control system;
Target paddle needs tobe selected and cut on site.
The maximum water operating pressure is
2.0MPa. The minmum water operating pressure
is 0.1MPa.

It is necessary to install water filter, otherwise
impurities and water scales will damage heat
exchanger. Installer and user must ensure
circulating water quality and no air in water system
to prevent the steel parts of heat exchanger from
being oxidized by air.

It is forbidden to connet the outlet signal of the
water pump in parallel,it may cause a damage to
the PCB.

Diagram 5.7 96 Adapter Pipe Accessory
The connection pipe is supplied by
field. After performing the flaring
work, connect the flare nut to stop
valve tightly.
For 96, the adapter pipe
accessories are supplied.
Weld the Φ22 pipe and adapter
pipe accessories, and then connect
the flare nut to gas stop valve
tightly.

Use moment spanner to connect water pipes,
any value above the upper limitvalue in table
5.5 is not allowable, otherwise, theplate heat
exchanger will be damaged.
Clean contact surface up while servicing braze
welding copper pipe, get ride ofgrease, brush
chlorate brazing flux and conduct weldingwith
40 55 silver content.
In process of welding, the allowable maximum
blaze temperature is 650 , nitrogen needs to
be aerated into refrigerant side toavoid oxidization.
