Product Overview

Condair RO-H description
Reverse osmosis system (from now on called RO) with reservoir tank for removal (>95 %) of salts and minerals in tap water. The systems are designed by Condair Ltd. with focus on reliable and hygienically correct solutions. The system uses a membrane separation process in which water molecules can pass through the membrane, while the majority of salts and minerals are retained and thereafter flushed out to drain. From the inlet, the water passes through a two steps of filtering before reaching the RO membrane. First step is an activated carbon filter to remove any residual free Chlorine in the inlet water. The second filter step is a sediment filter to remove particles above a size of 5 µm.

Inlet water quality requirements
The quality of the water being used in the Condair RO-H System should be checked before system commissioning. The RO-H system must be connected to a clean, potable drinking water quality mains. If the inlet water does not meet the quality specified in the preconditions table in Chapter 3.3, it may be necessary to install additional water treatment.

Installation considerations
Do not install the RO-H in a room that often surpasses an air temperature of 77 °F. Also keep installation away from heat-producing applications, such as boiler, central heating etc.
Observe the following restrictions concerning the length of piping:

• Junction from tap water line to RO inlet: max. 6.5 ft
• RO to tank: max. 6.5 ft
• Tank to product inlet: max. 9.8 ft
• RO to drain siphon: max. 16.3 ft

Installation Condair RO-H

Important notes on installation

• WARNING! Do not retighten/unscrew hoses while the system is pressurized!
• CAUTION!
  • Do not use oil, grease, glue, silicon, O-ring lubrication, etc.
  • when assembling pipes or hose connections.
  • All of the above products can act as food for bacteria and are thus pose health risks.
  • Only approved lubricant: Liquid dish soap.
  • Wash your hands before or wear clean gloves while assembling parts in direct contact with water.
  • Keep dust covers on pipes and hoses until just before assembly.
• CAUTION! Do not fasten the pump station or hoses/pipes to vibrating installations.

1. Water piping and connections
   The following flow diagram shows the needed fittings and their placement for RO-HM. Please follow the information strictly.

Installation of filters and RO membrane
CAUTION! The first time a new RO membrane is to be used, it is important to flush out any preservation fluids so that they do not end up in the system.

Maintenance

For regular maintenance please consult the full Installation, Operation and Service Manual.

Maintenance work
To ensure safe, hygienic and economic operation of the RO-H, vital components must be checked and maintained periodically according to the table below. The maintenance intervals and maintenance work stated below are guideline values. Local conditions, quality of the water etc. could influence the maintenance intervals. The relevant personnel is responsible for any maintenance work not carried out.
