1. Installation
Th e HDF, who's discharge capacity is as in Fig. 1, is
installed as follows:
Note: Before connecting the drain, blow compressed
air through the piping in order to thoroughly clean
out any impurities within it.
• Install the drain at a level below the receiver (Fig. 3);
if not the receiver will fi ll up with condensate (Fig. 4).
• To allow air equalization, install one of the follow-
ing:
a) the connection nipple, if supplied (with balancing
pipe), which must be connected between the drain
and receiver without any extra pipe or fi lter (Fig. 5).
b) a ¼" tube between the drain and the receiver (Fig.
6 - coupling for receiver available on request) or the
receiver's air outlet tube.
Discharge can be 'free orifi ce' or using a tube, also
above the drain (Fig. 7).

2. Maintenance
Weekly: open and close the drain valve as shown in
Fig. 5 and let air blow through for a few minutes.
If a signifi cant amount of water (more than 0.5 litres)
exits the valve during this operation then the drain
must be thoroughly cleaned as below.
Yearly: Dismantle the drain (Fig. 8) and clean all
components, especially '4'.
N.B.: Also perform this operation both 1 and 3 weeks
aft er installation.
Note: Th e drain's seal (10 - Fig. 8) can be simply
inverted when one side becomes worn.
