2. FEATURES TRUE DUAL CIRCUITS BPHE The true dual BPHE puts the secondary circuit (water) in contact with 2 primary circuits (refrigerant). So even if one primary circuit is shut off, each secondary channel is still in contact with a primary channel. INVERTER COMPRESSOR Inverter compressor is programmed to run at the optimum speed, which is regulated by the input frequency as it can varies according to the heat load requirement.

SPECIAL PRECAUTIONS WHEN DEALING WITH REFRIGERANT R410A UNIT 1) WHAT IS NEW REFRIGERANT R410A? R410A is a new HFC refrigerant which does not damage the ozone layer. The working pressure of this new refrigerant is 1.6 times higher than conventional refrigerant (R22), thus proper installation / servicing is essential. 2) COMPONENTS Mixture of composition by weight : R32(50%) and R125(50%) 3) CHARACTERISTIC • R410A liquid and vapor components have different compositions when the fluid evaporates or condenses.
d) When charging R410A, ensure that only liquid is being withdrawn from the cylinder or can. This is to ensure that only the original composition of R410A is being delivered into the system. The liquid composition can be different from the vapor composition. Dip-pipe Invert cylinder without dip-pipe Liquid withdrawal e) Normally, the R410A cylinder or can is being equipped with a dip-pipe for liquid withdrawal.

! WARNING • All terminals and connection must be tightened. • Avoid any wires from touching the refrigerant pipe. Apply insulation if necessary. • Avoid any wires from touching the moving components such as, fan motor, pump & compressor. WATER PIPING SYSTEM SETUP • • Fill up the water circuit after connecing all the pipes and equipment. Perform leak checks for all connections and joints. Do not start the unit when the system is leaking.
CONTROL OPERATION GUIDE The unit is equipped with a microprocessor controller board. The microprocessor contorller is provided to give temperature control for the system by accurately measuring and controlling the water entering and water leaving temperature. The temperature setting in the unit is preset in the factory. It is not recommended to change the setting unless necessary. A wired contoller handset is connected to the microprocessor board.

12. SERVICING AND MAINTENANCE SERVICING Servicing or maintenance of these unit must be carried out by experienced personnel with specific training in refrigeration. Repeated check the safety devices and continuous cycling of control components must be analyzed and corrected before being reset. The simple design of the refrigeration circuit totally eliminates potential problems during normal unit operation. No maintenance work is needed on the refrigeration circuit as long as the unit is operating normally.
13. TROUBLESHOOTING When a malfunction of the unit is detected, immediately switch off the main power supply before proceeding with the following troubleshooting procedures. The following are common fault conditions and simple troubleshooting tips. If any other fault conditions that are not listed occur, contact your nearest local dealer. DO NOT attempt to troubleshoot the unit by yourself.
