Installation
(continued)
Fig. 13
Prepare the ammonia pipe work with the weld
flange according to fig . 12 and 13 . The main/
drain piping should never be smaller than inner
diameter Ø37 .
Establish the support construction able to carry
57 kg (126 lbs) .
Lift the purger into position using the lifting eyes
on each side of the cabinet .
Connect the weld flange with the purger flange
using the enclosed flat gasket and tighten the 4
bolts diagonally to a torque of 60 Nm (44 .3 ft-lb) .
Insert 4 bolts through the purger frame and the
support construction and tighten .
Perform a leak test to ensure tight connection .
In case the purger unit needs to be dismantled
please contact Danfoss for instructions .
Establish a proper pipe/hose from the purge
solenoid valve for blow-off of NC gases according
to local or national regulations .
Prepare an outside water tank with a maximum
of 200 liters (53 gal .) and make sure the piping
allows the purged gas to be immersed in the
water .
Regularly check the Ph value of the tank’s
contents .
The Ph value should never exceed 12 .6 else the
content must be renewed .
Dispose of highly concentrated waste water
according to local/national regulations .

Note: Prior to replacing the water in the
water tank it must be secured 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/escaped .
Watch out for bubbles.
Establish a procedure for regular check of
Ph and bubble pattern .
If continuous bubbles are observed in
the water tank during ‘‘stand by” (Green
light indicator) in normal operation the
purge solenoid valve needs repair or
replacement .
