Installation Note: A triple evacuation procedure is recommended for Pressure Testing all new systems or where moisture is suspected. Never use oxygen, dry air, or acetylene for • pressure testing of the system as these may Once the system is isolated and the vacuum pump is switched off, any rise in pressure indicates that either form an inflammable mixture.
• • The unit is equipped with a motor circuit breaker with Check compressor suction superheat. This should be thermal overload and magnetic trip short circuit between 10K and 20K for normal operating protection for the unit. It was preset from factory and conditions.
Adjustment on DNS-D306 Pressure switch settings • High Pressure Cut Out: Turning the adjusting screw (8) clockwise to increase the cut-out pressure setting and Both the LP and HP switch settings must be adjusted to vice versa. Lock the spindle with locking plate after suit application before starting the unit.

whereas a suction superheat that is too high will not Vapor Injection Controller EXD-HP1 provide enough cooling effect for the compressor and (Applicable to EVI units only) will cause high discharge temperatures. In either case, it is likely that compressor damage/failure will occur. The controller EXD-HP1 used in the EVI units operates as an economizer control.
Manual mode operation Figure 10: Display/ keypad unit (LEDs and button • functions) Manual mode is intended for temporary operation of the valve at specific condition. Warning: All alarms are disabled during manual operation. We do not recommend unattended operation of the system during manual control.

F-Gas Requirement The models of equipment covered in this Technical Manual rely on fluorinated greenhouse gases for their functioning. All unit models come from the factory pressurized with OFN (Oxygen Free Nitrogen) only. In F-Gas Regulation EU 517/2014, the requirement for leak testing on the system is based on the charge size in tonnes of CO equivalent.
