1. General Description
Please read through this operation manual before using and
installation to avoid damage of the machine and personal injuries.
STM- PW series high temperature water heaters are used to heat up the
mould and maintain temperature, although they can be used in other similar
applications. High temperature water from the mould is returned to the
cooling tank and cooled by either indirect cooling ( For high temperature
models ) or direct cooling ( for standard models ). It is then pressurised by
the high - pressure pump, sent to the heating tank and finally to the mould
with a constant temperature. The OMRON temperature controller can
o
maintain an accuracy of 1 C.

General Description
3. Main Functions
SHINI Hi-temp. Water Heaters are mainly used to heat up the mould and
keep its temp. at a certain level, and they are also found applications in
other similar fields. Water returned from the mould will be cooled by
indirect cooling and then it is sent to pipe heaters to
be heated to keep a constant temp. of process water. Owning to
aximum 160
by a high pressure
ptimizing design, m

3. Main Functions
High-temperature water returning from mould returns to cooler through pipes,
which is conveyed to heater after being pressured through pumping and it is
transmitted to mould after being heated in electric thermal pipe, so on and so
forth. In this process, when liquid level switch detects that liquid level falls
down to set value, the water replenishing electromagnetic valve is started,
which replenishes water to ensure normal operation of the system; If the
water temperature is too high, the system will start up cooling electromagnetic
valve and cooled water will enter the system to cool water at high temperature
indirectly and reduce its temperature, by which the purpose of maintaining
constant temperature is achieved. If water is still at high temperature and
maintains at the level of the set EGO temperature, system will start up high
temperature alarm and stops working; When system pressure arrives at set
value of safety valve, safety valve is started and starts releasing pressure; If
system pressure keeps rising, which is higher than the set value of pressure
switch 2, system will start up water replenishing electromagnetic valve to
release valve; if the pressure of cooled water fails to reach the preset
requirements, pressure switch 1 will emit signal, system starts up
low-pressure alarm and stops working.

4.1 Signs and Labels
In order to keep a stable temperature,
cooling water pressure should not be
2
less than 2kg/cm, but also no more
2
than 5kg/cm. Clean the Y type
strainer to ensure cooling capacity of
the machine.
(Attached to pump cover)
This is to indicate motor rotating
direction. When phase reversal
happens, the alarm sounds and
indicator on control panel will indicate.
Please exchange the place of two of the
electrical wires to solve this problem.
High voltage! Electrical shock may
happen. Carefulness is required from
the operator.
Attentions!
This is general warnings which
operators should pay attention to.

4.2 Operation Regulations
1) Before operation, make sure that cooling water is clean soft water without
pollutants.
Low quality water brings limescales, which may cause problems.
2) If problems of drainage or bad temperature control are noted, please clean
solenoid valve and cooling water inlet and outlet.
3) Do not move the unit when it is in operation.
4) When in need of repairing, wait until oil temperature falls below 30 .
5) Motor overload may be caused by phase shortage, pipe obstruction,
broken bearing , etc. Motor overload relay will trip off to stop the machine
when this happens. Fixing the problems, press RESET on overload relay
to clear the alarm.
6) Before turn off the pump, wait until oil temperature falls blow 50 . Or the
life of the unit would be affected.
7) If the setting temperature is below 100 , then the pressure switch setting
value should be 1.5-2 bar; If the setting temperature sets between 100
and 200 , then the recommendable pressure switch setting value should
be 2.8 bar. If the cooling water pressure is too low, then the pressure
switch setting value can be adjusted properly to ensure normal running.
However, it may affect the limitation of setting temperature or cause
unstable temperature control.
8) Please connect the coolng water outlet with high temperature resistant
pipe when temperature is above 100 .
Please abide by the safety guide when you operate the machine so as to
prevent damage of the machine and personal injuries.
All electrical components should be installed by qualified electricians.
Turn off main switch and control switch during repair and maintenance.
