VARSHA H4 – Hydro Foam Nozzles have been designed for wide flow range for use with HD Monitors. These are fixed flow nozzles, simple and rugged  with superior stream and reach. The straight stream  from maximum reach can be easily changed to wide fog pattern under flow condition by rotation of the pattern adjustment sleeve. It is a self inducting nozzle equipped with a foam concentrate pick up tube of 3.0 meters long with a swivel connection.
The nozzle can be used as a water nozzle and when foam supply is established, it acts as a self inducting foam nozzle. The performance data shows effective stream trajectory in stand still air condition. The maximum overall reach of last drop is approximately 3-5% more than the effective stream performance data. The jet stream may get effected considerably with tail or head wind. MAINTENANCE The nozzle must be inspected regularly for possible damage or dirt around the moving parts. If any  abnormal conditions observed such as poor discharge, excessive wear, water leak, corrossion effect, damage etc., then nozzle must be taken out of service and repaired by qualified technician. The debris trapped in the nozzle may effect the
nozzle performance. To remove trapped debris, the water flow must be stopped and thereafter carefully unscrew and remove the nozzle deflector. Clean the nozzle and reassemble. While reassembling the nozzle or as a normal preventive maintenance, water proof lubricant must be used on
seal and moving parts for smooth operation. The nozzle must be operated periodically under full flow jet as well as under fog pattern. Under normal condition water must be flown through the nozzle periodically and dirt from around exterior moving parts must be cleaned, allowing nozzle to
operate properly. The nozzle must be inspected prior to and after each use. Greasing the moving parts and ‘O’ ring is required periodically. Over a time the seals may need to be replaced. The owner is responsible for maintenance of the nozzle in proper operating condition. After use with foam, flush with fresh water.
A trained personnel for fire fighting, with appropriate guidance and training must use the product to reduce the risk or injury. The nozzle must be fixed to the monitor carefully. The mismatched or damaged threads may cause leakage or uncouple the nozzle under operation. Application of water or foam on an electric appliance can cause serious injury by electrocution, as water is   conductor of electricity. The water supply to the nozzle must be gradual.
Sudden surge of water supply must be avoided. The monitor mounting must be supported properly to support the nozzle reaction force. Maximum permissible suction lift is 2 meters. NOZZLE OPERATION INSTRUCTIONS
To change spray angle, rotate the pattern sleeve clockwise for straight stream & anticlockwise to    spray / fog pattern
