 Danger

Risk of death when working on component parts and systems with U >= 30 V alternating voltage (AC) or U >= 60 V direct voltage (DC)

Do not touch damaged or defective live component parts and lines or non-insulated electrical connections and lines.

AS00.00-Z-0035-01A

 Danger

Risk of explosion caused by welding or soldering work on closed air conditioning system. Risk of poisoning caused by inhaling overheated refrigerant vapors. Risk of injury to skin and eyes caused by contact with liquid refrigerant.

Never perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated areas. Carry out repair work on the air conditioning system circuit only after the system has been drained.

Remove screw (2)

 Model 169 (except 169.090), 245 (except 245.286)Bolt, high-pressure line to coolant reservoir

*BA83.30-P-1004-01G

5

Pull refrigerant line (3) out of refrigerant reservoir (1) and place to the front

 Installation: Replace sealing ring of refrigerant line (3) and moisten with compressor oil.

6

Seal opening of refrigerant line (3) and opening of fluid reservoir (1) using suitable stop plug


The opening of the refrigerant line (3) and the liquid reservoir (1) must be sealed,
Otherwise penetrating dirt and moisture will damage the components that are connected to the refrigerant circuit.

7

Remove screw/bolt (4)

 Model 169 (except 169.090), 245 (except 245.286)Bolt, condenser to coolant reservoir

*BA83.30-P-1005-01G

8

Remove screws/bolts (5)

 Model 169 (except 169.090), 245 (except 245.286)Bolt, coolant reservoir to condenser

*BA83.30-P-1007-01G

9

Push refrigerant reservoir (1) to one side until refrigerant line (6) is exposed

 Installation: Replace sealing ring of refrigerant line (6) and moisten with compressor oil.

10

Remove fluid reservoir (1)

 Installation:
The packaging of the new fluid reservoir (1) must not be damaged. Ensure that the new fluid reservoir (1) is installed and the entire refrigerant circuit closed no later than 20 minutes after opening the package at the latest,
as otherwise the function of the fluid reservoir (1) can no longer be ensured.
