6) Inspect all plumbing connections in the unit for leakage. Temperature
variations during shipment may cause plumbing connections to seep when
initially started on-site. Secure the power to the unit and repair any leaks
prior to proceeding. Once the leaks have been repaired, re-energize system
and open the water source.
7) Begin closing the Black knob,
Concentrate Needle Valve V-40
,
in the
closed
position by slowly turning the handle in the clockwise direction.
While observing the
Membrane Inlet Pressure Gauge PI-25
and the
Concentrate Flowmeter FI-40.
The pressure should rise to about 552 kPa
(80 psi) and the concentrate should be about 227 LPH (60 GPH).

WARNING
Pressure, as indicated on the inlet side of the
RO Membrane Array
gauge, should never exceed 1400 kPa (200 psi).
8)
Observe the
Product Flow
meter. This flow meter indicates, in
liters per hour (LPH) and gallons per hour (GPH), the product water
flow rate. Record the product flow after 5 hours of operation (use the
sample Operational Log sheet provided in Figure 5.1).

Observe the
Concentrate Flow
meter. This flow meter indicates, in
