1. Prepare the ammonia pipework with the weld
flange according to Fig. 13 and Fig. 14. The
main/drain piping should never be smaller
than inner diameter Ø37 mm (1.5 in).
2. Complete the supporting structure able to
carry 100 kg (221 lbs).
3. Lift the purger into position using the lifting
eyes on each side of the purger’s cabinet.
Remove the rubber plug from the flange
opening.
4. Connect the weld flange with the purger flange
using the enclosed flat gasket and tighten the
supplied 4 bolts diagonally to a torque of 60 Nm
(44.3 ft-lb).
5. Insert 4 bolts (not supplied) through the purger
frame and the support construction and tighten.
6. Perform a leak test to ensure an airtight
connection.
7. In the event the purger unit needs to be
dismantled please contact Danfoss for
instructions.
8. Correctly install a suitable pipe/hose from the
purge solenoid valve for blow-off of NC gases
in accordance with local or national regulations.
Note: Prior to replacing the water in the
water tank ensure that the purger is
switched off and the shut off valve at the
flanged purger inlet is closed. Leave the
unit in this condition for a period to allow
the remaining gas in the piping to be
dissolved/released.
Watch out for bubbles.
Establish a procedure for regular
checking the pH level and bubble pattern.
If continuous bubbles are observed in the
water tank during ‘‘stand by” (Green light
indicator) in normal operation, one or
more of the purge solenoid valves needs
repair or replacement.
9. Prepare an outside water tank with a maximum
of 200 liters (53 gal.) and ensure the piping
allows the purged gas to be immersed in the
water.
10. Regularly check the pH level of the tank’s
contents.
11. The pH level should never exceed 12.6.
Otherwise the water content must be renewed.
12. Dispose of concentrated waste water in
accordance with to local/national regulations.
