… Make sure that the dampers move freely in their correct positions and that they operate correctly.
… If the unit is provided with a cross flow heat recovery exchanger, it is designed to resist at the nominal
(1) Conditions: Water entering/leaving temperature: 7/12 °C, Air inlet temperature 27/19°C DB/WB - Nominal air flow
(2) Conditions: Water entering/leaving temperature: 50/45 °C, Air inlet temperature 20°C DB - Nominal air flow
differential pressure indicated on the technical sheet, so all dampers and interception devices must be opened.
(3) At high speed with nominal air flow.
(4) Water entering/leaving temperature 90/70 °C, air inlet temperature 20 °C DB, Nominal air flow.
This action should be interlocked to the control system.
…
(5) A rectangular glass wool duct 1m50 long is placed on the blower.The measurement is taken in the room containing the blower unit.
Fan motor
Heat exchanger operating limits:
Check that the fan revolves freely by turning the impeller manually and verify that no foreign bodies are lodged
… FWD:
*water temperature: max 100° C
in the fan scroll.
*absolute service pressure: min 1 bar/max 11 bars
Remove the locking block under the motor-fan base frame.
…
Accessories - Hot water coil:
*water temperature: min. +2° C/max. 100° C
Check that the fixing screws on the belt pulleys are tight (see Figures 18 and 19).
…
*absolute service pressure: min 1 bar/max 11 bars
Check the fan belt tension and pulleys alignment. Realign and retighten if necessary (See Maintenance section).
…
Make sure that the dampers move freely and that any transport packing has been removed.
…
… Check the motor connections and make sure that the correct voltage supply is being used. Verify the lubrication
of fan and motor bearings (See Maintenance section and follow the motor manufacturer's recommendations).
Bearings could be pre-lubricated. Start-up may be noisy until grease is evenly distributed. Please refer to the
…
individual supplier's installation, operation, and maintenance manuals for additional information.
… If adjustable pulleys have been fitted, ensure they are positioned in the correct ratio. The setting is done at the
factory and should not require further adjustment. If adjustment must be made, refer to the section about pulleys
in this manual.
Fan must not work with interception device closed, like dampers, in order to avoid permanent deformation of the
…
structure. Dampers must be open during fan operation. Trane cannot be held responsible of structural damages
due to that.
