Novenco Climaster ZCR 1. General Introduction The instructions describe installation and maintenance of both unit casing and all components, which may be included in the unit. Therefore, components, which are not included in the current unit, will also be described in the instructions. In the table of contents all sections are described and numbered, and both installation and maintenance instructions are collected under one heading. 2. Handling 2.1 Weight The total weight and dimension are stated on the dimension drawing and weight lists. 2.2 Assembled units An assembled unit type ZCR can be...

For storage longer than 6 months, Vbelt drive should be loosened. Air Handling Units are not to be used as working platforms. If access to the roof is unavoidable the roof should be covered with sheet plywood. In addition protection should be provided to junction boxes, door handles, dampers etc. to avoid them being used for climbing. 5 Installation of Base Frame The air handling units are provided with a base frame onto which the sections are assembled, mounted and fixed with bolts. The base frame consists of two longitudinal girders stabilized by transverse girder stiffeners. 5.2 Pipe layout...

ball so that it is tight also without being filled with water. Connect the water trap to the drain from the drip pan of the unit. All drains from drip pans in the unit are with thread (1½" BSP male). In order to work, the height of the water in the water trap (H-measurement) must be higher than the pressure height in the unit (Dp inside/ outside in the unit at the water trap). Example.: Dp = 1300 Pa. The Hmeasurement must be at least 130 mm and to this must be added the increased pressure loss for fouling of the filters and also 10 mm for safety: minimal 300 Pa corresponding to 30 mm. This results...

it is necessary to replace the adhesive sealing strip. Pipe and cable inlets must be leakage-free. Check at intervals that duct connections and flexible connections are leakage-free. 6.5 Conditions near the air handling unit Air intake must be kept free of foreign material (paper, leaves etc.). Recommended cleaning intervals (Please see the individual components as well): General inspection: Once a month. Minor internal cleaning: First time after 1 month of operation. Afterwards every third month. Filter check: First time after 1 month of operation. Afterwards every third month. Check of remaining...

7.2 Maintenance In practice the SJD damper is maintenance-free, but make sure that the damper is kept clear of dust and dirt. This applies to both air path and regulating mechanism outside the air path. The damper regulating mechanism must always be well greased, e.g. with graphite grease, where moving metal parts slide against each other. Pay especially attention to this if the air stream has a degreasing effect. supplemented by a pre-filter of the basic filter type. The filters, marked with type, are inserted in retainers and fastened by means of locking rails which press the filter frame against...

8.5 Replacement filters Contact Novenco for ordering correct filters. - Filter type order No. 9. Rotary Wheel Type Heat Exchanger Panel filters Pocket type filter The rotary wheel type heat exchanger consists of a rotor and a drive system. The rotor has internal ball bearings and is fastened to the casing by screws through an adjusting disc (eccentric), a slot in the frame and a disc at the end of the shaft fig. 9.1. and 9.2. Location of brush seal, purging sector, measuring taps and a drive system Compact filter Aluminium filter In ZCR 9/6 to 13/8 the brush strip forming the seal along the circumference...

seal at the discharge side of the fresh The purging sector and drive system are located as shown on the sketches tary wheel type heat exchanger. The drive system is as standard a geared motor for constant rotor speed. Alternatively, a system for automatic control of the motor speed, i.e. for operation with varia- ble speeds, can also be delivered. The drive system is mounted in the return air part of the rotary wheel type heat exchanger. Fig. 9.3 and fig. 9.4 control box and motor are located EMS system for automatic opera- tion of the rotor is easy to use as the drive system does not require...

If the gap is not exactly the same along the whole circumference of the rotor, it must be adjusted: Remove cover above adjusting screw, fig. 9.5. Loosen screw in shaft end and adjust rotor by means of the adjusting disc till gap between rotor and casing is exactly the same along the whole circumference of the rotor, fig. 9.6. In ZCR 9/4 up to and including 18/ 10 the wrench opening is 32 mm for the adjusting disc. In ZCR 18/12 and 18/15 the wrench opening is 41 mm. After adjustment remount cover above adjustment disc, fig. 9.5. Check at suitable intervals during the working period that brush...

9.5 Rotor bearings The rotor bearings are ball bearings which cannot be re-greased. When the working lives of the bearings have come to an end, they must be replaced. The replacement should be carried out by a serviceman. 9.6 Belt drive The belt drive has an elastic belt which does not require any maintenance. The elasticity of the belt is referred to as belt tension. The rotor can be provided with a spare belt, if ordered when ordering the unit. If the belt bursts, use the spare belt and provide the rotor with a new spare belt at the first opportunity. This work should be carried out by a serviceman...
