Panasonic CS-F24DB4E5 Service Manual page 51

For the use of a gas cylinder without siphon inside, turn it upside down and use it.
(We recommend manifold with sight glass.)
Caution Do not use a "CHARGE CYLINDER".
Caution As a rule, please collect all existing refrigerants in the system outside the system when the refrigerant leakage occurs by the
system.
After that, please fill new refrigerant of a regulated amount again.
DRY VACUUMING
• • • • If vacuum pump possible vacuuming until less than -100.7kpa.
1. Running vacuum pump at both liquid and gas side for more than 1 hour and vacuuming until -100.7kpa.
2. After that keep the pressure -100.7kpa for 1 hour and confirm the vacuum gauge value not increasing.
3. If vacuum gauge value is increase, there is possibility of water inside the unit or there is any leakage.
10.5.3. Regarding handling
Handling the unit by hold the handle at compressor side and hold the basepan bottom at fan side.
10.5.4. Selecting the outdoor unit installation locations
• • • • Select location which satisfies the following condition, and then confirm with the customer that such a place is satisfactory
before installing the outdoor unit.
1. There should be sufficient ventilation.
2. The outdoor unit should be sheltered as much as possible from rain and direct sunlight, and the air should be able to move around so
that hot and cold air do not build up.
3. There should not be animals or plants near the air outlet which could be
adversely affected by hot or cold air coming out from the unit.
4. The outlet air and operating noise should not be a nuisance to other occupants
nearby.
5. The location should be able to withstand the full weight and vibration of the
outdoor unit, and it should also be level and safe for the unit to be installed.
6. The intake and outlet should not be covered.
7. There should not be danger of flammable gas or corrosive gas leaks.
8. There should be as little back-ventilation (air blowing directly onto the fan) as
possible.
(If strong wind blows directly onto the fan, it may cause problems with normal
operation.)
• • • • If you know which direction the prevailing wind comes from during the
operating season, set the outdoor unit at a right-angle to this wind direction,
or so that air outlet faces toward a wall or fence.
• • • • If there are obstructions near the outdoor unit and the wind direction is not
constant, install an optional air guider.
9. Do not allow any obstacles near the outdoor unit which will interfere with air flow around the air intake and air outlet.
10. If installing in a location which is prone to snowfall, place the installation base as high as possible, and be sure to install a roof or
enclosure which does not allow snow to accumulate.
11. Avoid installing the unit in places where petroleum products (such as machine oil), salinity, sulphurous, gases or high-frequency noise are
present.
