If the outdoor air heat content or temperature is below that of the return air temperature, the fresh air damper opens and the return air damper closes to assist with the first stage of cooling. The compressor will then operate to provide more cooling if required.

F I LT E R S ( PA N E L A N D / O R B A G F I LT E R S )

The PacAir RTU INV series package units will be provided with a set of filters. These are located inside the filter section in a cardboard box, only remove and install the filter 24 hours prior to commissioning the unit. Please refer to the technical data and order confirmation for the filter class included with your order.

R E F R I G E R AT I O N S Y S T E M

The PacAir RTU INV series package units come with either a single, two or four independent refrigeration circuits. The VSD compressors configuration will be either, one, two or four compressors to provide the flexibility and economy of operation, i.e. utilising one or two circuits as conditions vary, plus the advantage of inverter starting. The refrigeration system has been charged with HFC refrigerant with R410a or (optional) R32 refrigerant. Analogue refrigerant gauges and tapping points are provided to measure discharge and suction operating pressures.

C O M P R E S S O R S

The Compressors are directional inverter scroll type compressors. The compressor lubricant is polyolester oil (POE). Please note, this oil absorbs moisture quickly if exposed to open air. On commissioning, the compressor must be checked for correct rotation (please refer to start up procedure).

O U T D O O R FA N S ( C O N D E N S E R FA N S )

Condenser fans are EC axial fans controlled by the units head pressure. The condenser fan speed is continuously variable via the 0-10 V DC control signal.

D U C T W O R K

A closed return duct system should be used. That may include the use of economisers or outdoor fresh air intake. The supply and return air duct connections at the unit should be made with flexible connection to minimize potential noise and/or vibration.

AIR HOOD FOR NON-DUCTED OUTSIDE AIR

Should the outside air be a non-ducted system, Pacific HVAC Engineering suggest a rain hood be added to prevent water penetration into the mixing box, filter and evaporator section. This is an optional accessory and can be supplied by the OEM.

If no hood is installed by the installer or sub-contractor to the outside air damper, a price for a rain hood can be obtained to be supplied by the OEM.

Use the supplied commissioning sheets to help you complete the following procedure:

1. Ensure the compressors are energised for a period of six hours prior to starting the system to ensure effective heating of the oil. Crankcase heaters are not fitted, the windings are heated through the compressor drives.

2. Check that the shipping block beneath the compressors have been removed and that the compressors are secure on their mounts.

3. Set the desired mode and temperature and start the unit.

4. Set the indoor fan speed to the desired airflow. The minimum and maximum airflow of the RTU INV unit have been set in its parameters and setting outside these values is not possible. A technician level password will allow access.

5. Check that all fan motors are free running.

6. Check condensate drain for free drainage.

7. Check that the air filters have been correctly installed and are clean.

8. Check air diffuser dampers are open if equipped.

Use the supplied Commissioning Sheet to help you complete the following procedure:

9. Check the tightness of all electrical terminals and sign the check label.

10. Switch on the unit after a six hour delay period for the crankcase heaters.

11. Check the supply voltage between each phase, neutral and earth.

12. Measure the current draw on each phase to the compressor motor and measure the current draw of each fan motor. Check all readings against the specified values in the wiring diagram.

13. Check that the outdoor air fan motors are running smoothly.

14. Test the operation of the reversing valve by running the unit in both the heating and cooling mode.

15. Check the supply air flow at each outlet.

16. Touch up any outdoor unit paintwork damage to prevent corrosion.

S E T T I N G S U P P LY A I R F L O W

Consult the PacAir RTU INV series package units Technical Manual for details of airflow and available static pressure. If the indoor air returning to the unit is regularly expected to be above 50% RH, then the coil face velocity should be limited to be 2.5 m/s or less. High humidity levels can occur in tropical or subtropical conditions, and/or when heavily moisture laden fresh air is introduced. Select a fan speed that avoids water carry-over problems.

The pLDPRO graphic display is an electronic device that is compatible with the previous PGD1 line terminals; it allows complete management of graphics by the display of icons (defined at application software development level), and the management of international fonts, in two sizes: 6x8 and 12x16 pixels, and acoustic signal through piezoelectric buzzer. The application software resides on the pCO controller and therefore the terminal does not require any additional software for operation. Furthermore, the terminals feature a wide operating temperature range (-20T60 °C), the index of protection of front panel of IP65.

P L D P R O I N S TA L L AT I O N

This terminal has been designed for panel installation; the drilling template measures 71x29mm, as shown in Fig.1. For installation, proceed as follows:

• Insert the terminal into the opening, and fasten the device to the panel using two lateral sliding plastic brackets, as shown in Fig.2.

• Finally, fit the click-on frame.

E L E C T R I C A L C O N N E C T I O N

• pLAN: Connect the telephone cable (code S90CONN00*) from the pCO controller to the connector provided (RJ12) on the rear of the terminal. As shown in Fig.3.

C O N F I G U R I N G T H E A D D R E S S

The address of the terminal can be configured only after having connected the power supply, using the RJ11 telephone jack (the factory default value is 32).

To access configuration mode, press the + ↓ + ↑ buttons together and hold them for at least five seconds; the screen shown in Fig. 4 will be displayed, with the cursor flashing in the top left corner:

• To change the address of the terminal (display address setting), press the button once, the cursor will move to the address field (nn).

• Use the ↓ ↑ buttons to select the desired value, and confirm by pressing again. If the value selected is not the same as the one saved previously, the screen shown in Fig. 5 will be displayed, and the new value will be saved to the permanent memory.

If the field nn is set to 0, the terminal will communicate with the pCO controller using “point-to-point” protocol (not pLAN) and the field “I/O Board address: xx” will not be displayed, as it has no meaning.
