will draw minimal current. To correct
motor rotation, change the phasing at
the main power terminal.
3. Check the supply voltage.
4. Measure the current draw on the
compressor motor and on each fan
motor. Check all readings against the
specified values - particularly the indoor
fan amps if the unit is installed in a free
blow application.
5. Fit R410A compatible gauges and
measure the suction and discharge
pressures.
6. Test the operation of the high pressure
safety control by switching off the
outdoor air fan.
7. Test the operation of the reversing valve
by running the unit in both the heating
and cooling mode.
8. Check that the motors are running
smoothly.
9. Check the supply air flow at each outlet.
10. Touch up any outdoor unit paintwork
damage to prevent corrosion.
OUTDOOR UNIT CONTROllER (OUC)
The Outdoor Unit Controller (OUC) includes
a temperature sensing head pressure
control which enables the system to com-
pensate for outdoor ambient temperatures
below 20°C on cooling cycle, and above
15°C on heating cycle. The OUC also has
features which protect against icing or
overheating of coils, rapid cycling of the
compressor and loss of refrigerant charge.
If the outdoor unit fans take some time
to begin rotating when the system is
powered on, or they don't appear to be
rotating appropriately while the compressor
is running, consult the OUC label on
the electrical box. If necessary, refer
to
temperzone
for further diagnostic
information.
MAINTENANCE
Weekly For First Four Weeks
1. Check indoor air filters (if fitted) and
vacuum or wash clean as necessary.
2. Check condensate drain for free
drainage.
3. Check compressor compartment for oil
stains indicating refrigerant leaks.
4. Check tightness of electrical
connections.
Six Monthly
1. Check the tightness of all fan and motor
mountings.
2. Check tightness of electrical
connections.
3. Check suction and discharge operating
pressures.
4. Replace indoor unit air filters (if fitted).
5. Check condensate drain for free
drainage.
Yearly
1. Check all refrigerant piping for chafing
and vibration.
2. Check the operation of electric heaters,
if fitted.
3. Check air supply at all diffusers.
4. Check for excessive noise and vibration
and correct as necessary.
5. Check for insulation and duct damage
and repair as necessary.
6. Remove lint and dust accumulation from
outdoor coil fins.
7. Touch up any outdoor unit paintwork
damage to prevent corrosion.
