1. General Description Read this manual carefully before operation to prevent damage of the machine or personal injuries. STM-HPW series water heater have both standard and high temperature models, which are used to heat up the mould and maintain temperature, they can be used in other similar applications as well.
1.1 Coding Principle 1.2 Feature 1) Standard configuration ● P.I.D. multi-stage temperature control system can maintain an mould temperature with accuracy of ±0.5℃. ● Adopts high efficiency water cycle pump, with which precise moulds and mould loop with minor diameter can achieve precise temperature control and high efficient heat exchange.

Chapter 6, which contains service instructions intended for service engineers. Other chapters contain instructions for the daily operator. Any modifications of the machine must be approved by SHINI in order to avoid personal injury and damage to machine. We shall not be liable for any damage caused by unauthorized change of the machine.
1.4 Safety Regulations Strictly abide by the following safety regulations to prevent damage of the machine or personal injuries. 1.4.1 Safety Signs and Labels Danger! The unit is designed to endure high temp, and high pressure. For safe operation, do not remove the covers or switches. Attention! The unit should be operated by qualified personnel only.
1.4.2 Signs and Labels Regularly clean the filter screen in the copper screw to avoid blockage and as well ensure an excellent working performance. This is to indicate motor rotating direction. When phase reversal happens, the alarm sounds and indicator on control panel will indicate.
1. To maintain temperature consistency, cooling water pressure must be higher than 2 bar at all time, but should never exceed 5 bar in any case. 2. Clean Y-shape Cooling Water Strainer periodically to ensure perfect cooling capacity. Water inlet: inlet for replenishing water and cooling water.
1.4.4 Transportation and Storage of the Machine Transportation 1) STM-PW series standard oil heater 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.
