7) In order to keep stable water temperature, cooling water pressure should
be 2~5bar.
8) 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.
9) Please connect the coolng water outlet with high temperature resistant pipe
when temperature is above 100 .
1.3.4 Transportation and Storage of The Machine
Transportation
1) STM-W series standard water heaters are packed in crates or plywood
cases with wooden pallet at the bottom, suitable for quick positioning by fork
lift.
2) After unpacked, castors equipped on the machine can be used for ease of
movement.
3) Do not rotate the machine and avoid collision with other objects during
transportation to prevent improper functioning.
4) The structure of the machine is well-balanced, although it should also be
handled with care when lifting the machine for fear of falling down.
5) The machine and its attached parts can be kept at a temperature from -25
to +55 for long distance transportation and for a short distance, it can be
transported with temperature under +70 .
General Description
1) STM-W series standard water heaters should be stored indoors with
OO
temperature kept from 5 C to 40 C and humidity below 80%.
2) Disconnect all power supply and turn off main switch and control switch.
3) Keep the whole machine, especially the electrical components away from
water to avoid potential troubles caused by the water.
4) Plastic film should be used to protect the machine from dust and rains.
