CLIVET MSAN-XMi 120T, Инструкция по установке и эксплуатации, Страница: 81 / 92

CAUTION
Signal wire is 3-core, polarized wire. Use 3-core shield wire to
prevent interference. The grounding method now is grounding the
closed end of the shield wire and opening (insulating) at the end.
Shield is to be grounded.(Reference distance: It is 300mm when
current capacity of power cord is less than 10A, or 500mm when
50A).
When power cord is parallel with signal wire, please put them
into separate wire distribution pipes, and leave a proper distance.
Display box, remote controller, and matched resistance are the
accessories of indoor unit; wire controller is optional, if necessary
please contact to the dealer to buy.
7. PRECAUTIONS ON REFRIGERANT
LEAKAGE
This air conditioner(A/C) adopts inncouous and nonflammable
refrigerant of R22,R410A,407C. The locating room of the A/C
should big enough that any refrigerant leakage is unable to reach
critical thickness.So certain esssential action can be taken on time.
Critical thickness------the Max. thickness of Freon without any
harm to person.
Refrigerant critical thickness: 0.3[kg/m

Refrigerant critical thickness: 0.35[kg/m

Outdoor unit
Indoor unit
Room full of leak refrigerant
(All refrigerant has run up)
Confirm the critical thickness through follow steps, and take
necessary actions.
1. Calculate the sum of the charge volume (A[kg]).
Total refrigerant volume of 10HP=factory refrigerant volume
+ super addition.
2. Calculate the indoor cubage (B[m]) (as the minimum cubage.
3. Calculate the refrigerant thickness.

Critical thickness
Counter measure against over high thickness
1. Installmechanicalventilator to reduce the refrigerant thickness
under critical level. (ventilate regularly).
2. Install leak alarm facility related to mechanical ventilator if you
can not regularly ventilate.

A. Ventilation peristome
(Leak hunting siren should be installed in
places easily keep refrigerant)
b. Leak alarm related to mechanical ventilator
8. TEST RUNNING
8.1 Check points before test running
1. If indoor and outdoor units have been installed properly.
2. Whether piping and wiring is correct.
3. Whether has taken leakage inspection to the refrigerant pipe
system.
4. Whether heat insulation has been properly applied.
5. If ground wire has been correctly connected.
6. Whether take a record of the piping length or refrigerant adding
amount.
7. Whether the power supply voltage is equal with the rated
voltage.
8. If there’s barriers around air inlet/outlet.
9. Open gas side and liquid side stop valve.
10. Connect to power supply and pre-heat the AC.
7.1 Important information for the used
refrigerant
This product has the fluorinated gas which is listed in kyoto protocol
it is forbidden to release to air.
Refrigerant type: R410A; Volume of GWP: 2088;
GWP=Global Warming Potential
Attention:
1) For equipment that contains fluorinated greenhouse gases in
quantities of 5 tonnes of CO
2
equivalent or more,but of less than
50 tonnes of CO

equivalent or more,at least every
three monthes, or where a leakage detection system is installed,
at least every six monthes.
4) Non-hermetically sealed equipment charged with fluorinated
greenhouse gases shall only be sold to the end user where evidence
is provide that the installation is to be carried out by an undertaking
certified person.
5) Only certificated person is allowed to do installation, operation
and maintenance.
