5.
First Use
Prior to first use any installation work and all checks must have been completed.
Check for proper water and power supply.
6.
Operation, Maintenance and Repair
All units are virtually maintenance free, however certain things should be observed.
Any maintenance and repair work must be performed by skilled and trained
staff only.
Before starting any maintenance or repair work the unit is to be completely
disconnected from the main power supply!
6.1
Heat Exchanger, Water Connections and Condensate Tray
It is recommended to vacuum clean the heat exchanger and the dry condensate tray on a regular basis.
The heat exchanger blades are sharp--edged. Wear gloves for protection!
Check water connections and heat exchanger for tightness and possible corrosion damages.
If corrosion occurs inside the heat exchangers skilled staff must check the water treatment.
In case of condensation and existing condensate drainage the condensate tray will have to be wet cleaned and
checked for contamination on a regular basis as required by VDI 6022.
6.2
Filter
Unit with filter
If a recirculated air filter exists it requires replacement about 2--3 months after first use of the unit. By that
time, it will probably be saturated from carpet lints and construction dust residues.
Exact timing is subject to local conditions.
The filter must be replaced on a regular basis, every 6 months to 2 years depending on dust formation.
A 6--month filter change interval will be required if the unit is operated in an environment with heavy dust
load, a lot of foot traffic, and only minimum primary air filter quality.
A 2--year filter change interval might be appropriate if the unit is operated under conditions without foot traf-
fic, in a clean environment, and with a very good primary air filter quality.
Unit without filter
The exchanger(s) is/are to be vacuum cleaned about 2 to 3 months after their putting into operation. By that
time, heat exchangers are usually visibly polluted from carpet lints and construction dust remainders. Exact
timing is subject to local conditions.
Heat exchanges will then have to be vacuum cleaned on a regular basis, every 6 months to 2 years depending
on dust formation. This gains particular importance considering that condensate formation might result in
hard--to--remove dust caking.
A 6--month cleaning interval might be required if the unit is operated in an environment with heavy dust load,
a lot of foot traffic, and only minimum primary air filter quality, in case of condensate formation on the cooler
even sooner.
A 2--year cleaning interval might be appropriate if the unit is operated under conditions without foot traffic,
in a clean environment, with a very good primary air filter quality and without condensate formation on the
cooler.
