2.0 INSTALLATION (refer to figure 1)
2.1 ESSENTIAL INFORMATION
Care must be taken to ensure that the dryer is not subject to flows (even peaks) in
excess of the dryers rated capacity, e.g. dryers downstream of an air receiver have
increased potential to be overflowed.
The dryer can be installed free standing, secured to the floor via the fastening points
provided in the base or secured to a wall using optional brackets.
The control enclosure (A) must be at the bottom and the dryer must be installed
vertical and level.
Two inlet and two outlet connections are available at the top of the dryer to enable
connection from either left or right. Unused connections (B) and (C) must be sealed
with the threaded plugs provided. Suitable rated pipe and connections must be used
for the installation. All pipework must be secure and safely positioned.
The purge flow is factory set for 6 bar g (87 psi g) minimum operating pressure.
Should the minimum pressure requirement be different, the purge flow must be reset
by a domnick hunter engineer or a domnick hunter approved agent.
Ensure the dryer is electrically connected to a supply suitable for the unit. See wiring
diagram printed in 2.3 Electrical Details.
1. Filtration
A 0.01 micron pre-filter is contained within the upper head assembly. 1 micron after-
filters are integral within desiccant cartridges screwed into inserts in the upper head
assembly.
Filters must be maintained by domnick hunter or a domnick hunter
approved agent.
2. By-pass Line (D)
A by-pass line, 3/8" BSP or NPT * (D) ensures complete safety during maintenance
and enables a continuous supply of compressed air to be maintained if required. It
should be remembered that air bypassing the dryer is dirty untreated air.
3. Valves (E, F, G)
Isolation valves, 3/8" BSP or NPT * are recommended on the inlet (E), outlet (F) and
bypass (G) lines at the positions indicated in Figure 1.
* When ordering, the thread type must be specified.
