Checks of component ones of systems of heating and to / in

Wide valve

 ORDER OF REALIZATION

  1. The motor begins and leave us that it works in 1.500 revolutions per minute inside not less than 5 minutes then they secure what in an outline of the pressure of high pressure established for 13,6 ÷ 15.5 atm.
  2. In the bad functioning of the pressure of valve in an outline of the low pressure it will reduce to the zero. Check the reception and the final parties of the desumidificador of receiver – will be an identic temperature.

Pressure switch

 ORDER OF REALIZATION

  1. The motor begins and leave it to work for 1.500 revolutions per minute.
  2. Establish the very turns of the supporter of a heater and the least temperature.
  1. Taken of sensor of separate pressure.
  1. One to positive probe of an ohmmeter to contact 4, and negative – to the contact of 1 capture and to be secured of the modification of the condutividade in the modification of the pressure of the refrigerant liquid. So the control of the magnetic union happens.
1 - the Outline of low pressure
2 - there is a condutividade
3 - it has not condutividade
4 - the Outline of high pressure
  1. One to positive probe of an ohmmeter to contact 2, and negative – to contact with 3 captures and to make sure of the modification of the condutividade in the modification of the pressure of the refrigerant liquid. So the control of the supporter of condenser happens.
1 - there is a condutividade
2 - it has not condutividade

Main alternation of a heater

 ORDER OF REALIZATION

  1. Take the main alternation of a heater of the block of meeting (to see the electric equipment of Front Side).
  1. The available condutividade certifies between contacts 1 and 2, and also 3 and 4. 1 and 2 gives the tension of battery in contacts and the available condutividade certifies between contacts 3 and 5. In unsatisfactory checks results they substitute the alternation.

Alternation of the magnetic union

 ORDER OF REALIZATION

  1. Take the alternation of the magnetic union of the block of meeting in a compartment of reason (to see the electric equipment of Front Side).
  1. The available condutividade certifies between contacts 1 and 2. 1 and 2 gives the tension of battery in contacts and the available condutividade certifies between contacts 3 and 5. In unsatisfactory checks results they substitute the alternation.

Condenser supporter

 ORDER OF REALIZATION

  1. The motor begins, establish the very speed of the rotation of the supporter of a heater, the least temperature and include К/В.
  2. One secures that the supporter of the condenser works in the low speed in a temperature of OZh the 90th hail., and also with a pressure less than 15 atm. In a temperature of 95 a hail. and the pressure more than 15 atm – the supporter will work in the high speed.
  1. The supporter of the condenser separates the capture of electrical system and join the battery recarregável and the ampermeter to his contacts. It is secured what the krylchatka of the supporter spins lisamente. The indications of the ampermeter will do 9.8 ± 1.5 one in a temperature of 20 a hail.
