Chapter 3: Installation

Pump room installation involves several consecutive steps. The installation process starts with the manual
installation and connection of the unit to the system that it controls, as described in this chapter. Once
physically installed, sensors and reagents must be inserted into the unit and the control system must be
started and calibrated, as described in Chapter 4, First Time Operation and Calibration. HydroGuard should
operate for several days in order to be properly tuned to its specific pool environment. Additional periodic
tuning, calibration, and maintenance are required after HydroGuard has been operating on a regular basis.
This is described in Chapter 5, Continuous Operation and Maintenance.
3.1

Selecting a Location

Take extra time in selecting a location since the installation location will determine the ease of the installation
and future operation and maintenance. The location where HydroGuard is installed is dependent on various
considerations:
Convenient Access - HydroGuard should be installed where it can easily be viewed and operated by pool
personnel.
Dry Area – HydroGuard handles electricity and includes electronic circuitry that is susceptible to short-
circuiting and/or corrosion when exposed to water or high ambient moisture levels.
Pool Chemicals - Pool chemicals can be corrosive to HydroGuard's electronic circuitry. It is highly
recommended that HydroGuard is not installed adjacent to the pool chemicals storage area or the dosing
systems themselves.
Minimum Distance from Pump - The water sampling line that is tapped into main circulation pipe, feeding
the HydroGuard should be as short as possible. A long sample line from the main circulation pipe to
HydroGuard creates an unnecessary delay between supply, measurement, analysis, and chemical dosing.
Drainage – The location should easily allow the outlet of the colorimeter to gravity drain without creating an
obstacle (i.e. pipe across walkway). The flow cell may be pressurized to allow for return to the system under
pressure.

Site Requirements and Installation

The HydroGuard assembly is wall mounted. It should be located on a wall where pool operators and service
technicians can easily access it for normal operation and maintenance. It is also advisable to install it where
the pool operator can easily view the readings and alarms. Finally, the complete unit with all connections
weighs 18 lbs. (8 kg), so, it must be mounted securely onto a stable wall. The HydroGuard unit measures
26.3" x 13.1" (66.8 cm x 33.2 cm). The base of the complete HydroGuard assembly should be mounted at
least 24" (60 cm) above the floor (preferably at eye level).

3.2.1 Mechanical Installation Requirements

The HydroGuard unit and its mounting panel are not shipped with mounting screws or anchors. The
installer must provide screws and anchors that can hold the weight of the HydroGuard unit, mounting
panel, intake filter, and electrical outlets and junction boxes. The screws and anchors must be
compatible with the wall where it will be installed.
