RHS 700
To observe the warranty on RHS 700, all components used for maintenance must
be identical to those in the service set, see Section 9.
To ensure problem-free operation of RHS 700, the station must be maintained in
accordance with the following:
The power supply to the station must be switched off.
For each 25 operating hours:
A large amount of the moisture evacuated from the A/C unit accumulates in the
vacuum oil and therefore it can be advantageous to change the oil from time to
time. The reason moisture accumulates in the vacuum oil is that the vacuum pump
does not create the required vacuum!
Changing vacuum pump oil:
-
Hold an oil beaker under the oil drain screw (pos. 34) and loosen the screw.
Allow the old oil to drain into the beaker.
-
Remove the oil filling cap (pos. 32).
Retighten the oil drain screw and fill with new oil through the oil filling stub (pos.
32) until the level reaches the centre of the sight glass (pos. 33).
