Test Running; Evaluation Of The Performance - Friedrich M09YJ Manuel D'installation

Test Running

- Check that all tubing and wiring are properly
connected.
- Check that the gas and liquid side service
valves are fully open.
Prepare remote controller
Insert batteries before using the remote con-
trol. The battery type used is AAA (1.5 V).
1

Anchoring of outdoor unit
- Fix the outdoor unit with a bolt and
nut(ø10mm).
- When installing on the wall, roof or rooftop,
anchor the mounting base securely with a
nail or wire assuming the influence of wind
and earthquake.
- If the vibration of the unit is transmitted to the
pipe, secure the unit with an anti-vibration
rubber.
Bolt

Evaluation of the performance

Operate the unit for 15~20 minutes, then
check the system refrigerant charge:
- Measure the pressure of the gas side service valve.
- Measure the air temperature from inlet and
outlet of air conditiioner.
- Ensure the difference between the inlet and
outlet temperature is more than 46˚F.
- For reference; the gas side pressure at opti-
mum condition is shown on table (cooling)
The air conditioner is now ready to use.
