maintenance a step further than RO and all the GS Series components are ready

2. PREVENTIVE MAINTENANCE
(1) The installation manuals of the GS Series of Gas Steam humidifier come with a
complete Maintenance chart in order to guide internal personnel in cleaning and
monitoring activities. Like any other appliance the Gas-Steam humidifier requires
monitoring to ensure efficient operation throughout the life of the unit.
(2) While in operation, the unit will blowdown scaled water through a drain pump
keeping control on the water concentration based on steam output. For longer
intervals between cleaning, the unit may be completely drained down to reduce the
mineral concentration and bring in new fresh water in the system.
(3) The FTBD (Full Tank Blow Down) can be activated through the software or dip
switches based on:
(a) Time of day setting. When the 25 - 400 hours interval (adjustable ) is reached
the unit will wait until the set time of day before activating the full tank
blowdown.
(b) External trigger using 24Vac signal from the building management system to
the input terminal of the humidifier.
(4) Following the full tank blowdown, the unit will refill and perform a float check.
Whenever possible, use this feature to reduce mineral accumulation in the system
and reduce the time required to clean the interior of the reservoir.
3. PRE-CLEANING SEQUENCE
(1) When cleaning of the reservoir is required, use the tank pre-clean feature. This
pre-cleaning sequence will drain the full content of the unit, fill back-up, and re-
drain any residual scale that has fallen from the cold water refilling. This sequence
is not an alternative to cleaning the humidifier, it is meant to reduce the time
required to clean the tank.
(2) Full Size Frontal Opening: Every GS Series Gas Steam Humidifier comes
complete with a full size frontal opening to allow bottom cleaning of the tank and
heat exchanger. This opening allows quick and easy cleaning without removing
the steam outlet of the unit.
