Greenway Home Products VPS1140 - Manual (Page 6)

3. Installation Instructions
3.1 Accessibility, Orientation & Fittings
Always mount the VPS1140 in a location that provides ample space for accessing the ultraviolet lamps. Service may require removing the UV
lamp and quartz tube. A minimum of 18”, (45 cm) of clear space should be provided on either the left or right side of the unit based on the
direction of installation of the UV lamp. As the VPS1140 generates heat during use, please ensure that no combustible items come into contact
with, or are in proximity to the system.
It is recommended that you maintain at least 6”, (15 cm) of clear wall space on all sides of the VPS1140 for cooling purposes. This will prolong
the operating life of the system.
CAUTION: Whenever soldering is required on any VPS1140 system component, always detach that component from the system first.
3.2 Optional Bypass Line and Drain Valve Installation
WARNING: To prevent contamination of water in the plumbing, which may pose a health hazard, do not use bypass line and valve if your source
of supply is untreated surface water or groundwater.
If your source of supply is treated municipal water, use of the bypass line and valve will permit uninterrupted treated water service in the event
of system malfunction.
Always test the bypass valve following each use of the bypass line, prior to re-starting the VPS1140 to confirm that the valve has been fully
closed and that only water from the outlet port will thereafter be going downstream.
The installation of a drain valve, while not required for system operation, is recommended for all installations of the VPS1140. The installation of
a drain valve will allow the service technician to drain the system of water prior to conducting any service on the unit.
A bypass system for the VPS1140 can be installed as outlined below:
