Check for leaks
Install insulation to overhead piping
Connect system power cord from unit to GFCI
Assembling the Unit
Step 1: Unpack the unit, being careful to remove all packaging material.
Inspect the unit for damage particularly the quartz sleeve
– See the
Accessing UV Chamber section. Check if UV lamps are fully inserted. Write
model number, serial number, & installation date on front on the Instruction
Manual.
Step 2: The UV unit has keyhole slots for convenient mounting
– use all four
mounts. Do not mount the unit directly to an outside wall; mount on
plywood or shims
– See Figure 4.1.
Remove the top and bottom covers of
the unit to make the mounting holes accessible. Mounting hole templates are
provided to simplify installation.
Step 3: If the optional Stainless flexible hoses have been purchased, connect
them now to both the top and bottom of the unit. Make sure that the sealing
washer is inside the hose end before making the connection. Hold the
stainless manifold with a wrench then tighten the hose securely.
Connecting the Pipes
Warning - Water must flow into the inlet at the bottom of the unit. The
outlet is located at the top of the unit.
For 1” systems, hold the
stainless manifolds with a wrench when tightening mating
connections. For
2” systems, the pump flange should be removed
and threaded into mating connection then reconnected to UV unit. Do
not damage sealing surfaces.
Caution: Always shut off the water supply and relieve the water pressure
before beginning any plumbing modifications.
Step 1: See Figure 4.2 on how to arrange the piping and optional devices
such as the solenoid valve, bypass line, sample ports and drain. If the
pressure tank is downstream of the unit, a purge valve relocation kit is
required (# GE3).
Step 2: The optional solenoid valve ensures that should the system fail, due
to power loss, low UVT or low UV lamp output, the system will fail in safe
mode and shut down the water flow. It is recommended install the solenoid
valve just after the UV unit provided that a flood detection device exists at the
site
– this allows the unit to purge during alarm situations. If a flood detection
device is not present, install the solenoid valve ahead of the UV unit. The
direction of flow through the solenoid valve is important
– verify flow direction
with label on the valve. Water will not flow backwards through the valve. Keep
the coil of the valve pointing upward (to prevent water from dripping on it).
The valve requires minimum 69kPa (10psig) to fully open.
The optional solenoid valve is normally closed and must be powered to open.
Some of the solenoid valves offered have a manual override (white lever) that
