 Assemble tube element system as follows:
-
while carefully turning insert tube element (8) with scale 41 - 75 mbar into fixed tube
element (7).
- while carefully turning insert tube element (9) with scale 81-115mbar into tube
element (8).
- while carefully turning insert tube element (10) with scale 121-115mbar into tube
element (9)
 Open connecting valves B, C and D
 Use bellow (12) to load a pressure pursuant to 1* into the test system.
 Close connecting valve C to avoid a loss in pressure.
 Wait 10-60 minutes (dependent on pipe volume) for loaded air and water temperatures to
equalize.
Prolong 10-60 minute period of temperature equalization if temperatures fluctuate
greatly. The equalization period can last up to two hours!
 Carry out the test over a period prescribed by 1*. Over this period the pressure indicated must
not drop.
5.3 Adjustment of gas admission pressure to atmospheric and blower burners using
water column up to 30 mbar
Complete test as described 5.2:
The fixed tube element (7) up to 30 mbar is sufficient for this test type.
 Connect gas appliance adapter (21) to the open end of the connecting hose (6).
 Connect the snout of the gas appliance adapter (21) to the test supply system of the gas
appliance.
 Set the gas appliance burner to the highest possible setting.
 Open connecting valves B and D.
 Read the actual gas admission pressure.
5.4 Initial test of drinking water systems of domestic connections
Complete test as follows:

Close all cut-off valves on your ROTEST GW 150/4.
 Insert connecting hose (6) to connecting valve A. An auditable sound is heard when hose
and valve nipple are properly locked.
 Insert open end of the connecting hose (6) to your adapter of the end of pipe. An auditable
sound is heard when hose and adapter nipple are properly locked.
 Use hand pump (3) to load a pressure pursuant to 1* into the test system
 Wait 10 minutes for loaded air and water temperatures to equalize.
Prolong 10-minute period of temperature equalization if temperatures fluctuate
greatly. The equalization period can last up to two hours!
 Carry out the test over a period prescribed by 1*. Over this period the pressure indicated must
not drop.
