Page 15: Wiring Diagram
7. Wiring Diagram Important Note: All wiring and connections to the condensing unit must be made in accordance to the local codes. SINGLE PHASE Series 2 MT: JEHBSCU0200M1, JEHBSCU0250M1, JEHBSCU0300M1 LRMSS0200AXV1, LRMSS0250AXV1, LRMSS0300AXV1 Series 3 MT: JEHBSCU0350M1, JEHBSCU0400M1 LRMSS0350AXV1, LRMSS0400AXV1... - Page 16 THREE PHASE Verification of proper rotation direction is made by observing that suction pressure drops and discharge pressure rises when the compressor is energized. Reverse rotation of a scroll compressor could results in substantially reduced current draw, suction temperature will be high, discharge temperature will be low and the abnormal sound is heard from the compressor.

Page 20: Safety And Health
8. Safety and Health Important Note Only qualified specialists could carry out the installation, maintenance and commissioning of the system. To avoid potential injury, use care when working around coil surfaces or sharp edges of metal cabinets. All piping and electrical wiring should be installed in accordance with all applicable codes, ordinances and local by-laws. -
Page 21: Installation & Commissioning
9. Installation & Commissioning Unit site location • In order to achieve maximum cooling capacity, the installation location for the condensing unit should be carefully selected. • Install the condensing unit in such a way so that hot air ejected by the condensing unit cannot be drawn in again (short circuit of hot discharge air). - Page 22 Installation clearances • The installation location should allow sufficient space for air flow and maintenance around the unit. • Space not less than1.5m is necessary for installation or maintenance. Compressor handling To ensure compressor reliability, the condensing unit together with the compressor must not tilt greater than an angle of 45°.
- Page 23 Field piping Important Note: Pipe sizing should only be determined by qualified personnel. All local codes of practice must be observed in the installation of refrigerant piping. To ensure satisfactory operation and performance, the following points should be noted for field piping arrangements: •...
- Page 24 Pipe Size Selection (For EVI unit Only) Sizing of liquid and suction lines for EVI model will be different from standard scroll models. Piping sizes of this model need to follow the recommended correction coefficient of cooling capacity. This is vital as if the pipework selected is oversized, especially for the suction pipe, the gas velocity will be decreased at low mass flow rate / low evaporating temperature, causing oil return problems.
- Page 25 Pressure testing • It is recommended to use inert gas such as nitrogen for pressure testing. • The pressure differential between the high and low side of the compressor should not exceed 30 bar (435 psig). • Test pressures are : 19 bar (275 psig) on the Low Side 28 bar (405 psig) on the High Side Leak detection •...
- Page 26 9.11 Electrical Important Note: The mains electrical supply to the condensing unit must be via a suitable motor rated circuit breaker or fuse. J&E Hall Basic Scroll condensing units require either a 230 volt / 1 phase / 50Hz supply or a 400 volt / 3 phase / 50Hz supply, both of which must include a Neutral and an Earth.
- Page 27 9.13 Running the unit • Run the unit and check compressor and condenser fan operation. • Check system pressures and temperatures, gas charge and running currents of motors to ensure correct operation. • Check compressor superheat. • Final adjustment of safety switches setting and fan speed controller. •...
- Page 28 9.14 Safety pressure switch settings The pressure switch fitted to JEH model condensing units with auto reset for Low Pressure and manual reset for High Pressure is NOT factory preset. BOTH THE LP AND HP SWITCH SETTINGS MUST BE ADJUSTED TO SUIT THE APPLICATION BEFORE STARTING THE UNIT.
- Page 29 9.14.3 Low pressure safety (Auto reset) The low pressure safety switch protects the compressor against deep vacuum operation, a potential cause of failure due to internal arcing and also operation outside the compressor limits. The low pressure safety cut out should never be set below the settings as shown in the following table. For systems without pump-down the LP switch signal contact shall be used to energize a low pressure safety alarm.
- Page 30 Safety Instructions: 1. Read installation instruction carefully. Failure to comply can result in device failure, system damage or personal injury. 2. Only person having knowledge and skill are allowed to manipulate the controller. appropriate 3. Disconnect all voltages from system before installation. Electrical Installation •...
