Failure to comply to the above instructions may result in equipment malfunction
and will void warranty.
Always use a backup wrench when making any threaded connection to the dryer.
Failure to use a backup wrench may result in damaged tubing and components
internal to the cabinet.
7.2 PIPING AND VALVES
Install piping, fittings and accessories as required for specific site conditions and
requirements. Figure 3 indicates a typical piping arrangement for a refrigerated dryer,
including dryer and filter bypasses. This figure can be used as a guide for valve and
accessory placement in the system.
ZEKS 1000 through 1600 HSF models come factory installed with a drain isolation
valve (D). The isolation valve permits maintenance of the automatic drain without
isolating air flow to the dryer. To operate dryer, all valves shown in Figure 3 are to be
closed except valves (B), (C) and (D). Valve (A) is used for bypass purposes and
valve (E) is for test and manual drain purposes.
7. INSTALLATION AND INITIAL START-UP
7.1 LOCATION AND MOUNTING
The dryer should not be located in an area where ambient temperature is likely
to exceed 113°F (45°C) or be less than 50°F (10°C). The dryer must be located in
an area that provides sufficient clearance from walls and other adjoining equipment
to allow easy access for servicing and maintenance requirements. A minimum of
30 inches is required to allow free flow of air to the condenser inlet and clearance for
servicing the dryer.
On installations with a relatively steady flow rate, the dryer is normally connected after
the air receiver. If loads fluctuate widely, the dryer should be positioned ahead of the
receiver and sufficient storage capacity downstream is necessary to prevent
excessive air flow through the dryer.
When installed after any compressor that causes significant vibration or air pulsation,
such as reciprocating compressors, proper vibration isolation and pulsation
dampening devices should be added to protect the dryer.
NOTICE
Dryers equipped with the optional SDD200H drain are shipped with a foam
material inside the drain housing to protect the internal components of the drain
during shipment of the dryer. The foam material must be removed and the
supplied 3/4” plug installed in the designated port prior to start-up.
