Installation Instructions for General Equipment
READ INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO ASSEMBLE,
SERVICE OR OPERATE XETEX AIROTOR UNITS. FAILURE TO COMPLY WITH INSTRUCTIONS
COULD RESULT IN PERSONAL INJURY AND/OR PROPERTY DAMAGE!
SPECIAL WARNING: No untrained person should attempt to
install, maintain, or service XeteX AIRotor units.
MOUNTING
- The drive unit (motor plus reduction gear) is mounted on the bracket located
in the heat exchanger, and the control unit is mounted in a suitable position
either inside the heat exchanger's housing, or in the control room. The
motor can be protected against bracket vibrations by, for example, rubber
anti-vibration mountings. The direction of rotation cannot be changed. In
the event of incorrect direction of rotation, the drive unit can be turned
180 degrees or exchanged for another model. An installation kit for the
motor can be ordered separately.
MOUNTING THE ROTATION MONITOR
- The magnet for the pulse generator - the rotation monitor - is screwed
tightly to the periphery of the heat exchanger. If the housing around the
rotor is itself magnetic, then the magnet must be isolated from the housing.
The pulse generator is mounted so that the magnet passes over it a distance
of 5-8 mm. The rotation monitor can be ordered separately.
Maintenance Instructions for Equipment
GENERAL
- The heat recovery unit is made to recover heat from the exhaust air and
put it into the uspply air. This will reduce energy demand and annual energy
consumption. Improper operation will cause less efficiency, higher energy
consumption, and a lower supply air temperature.
- Some reasons for low efficiency can be low rotation speed and/or contamination
of dust in the channels of the rotor.
PROCEDURES
IMPORTANT! Before doing anything, disconnect electrical power to unit.
Also, avoid touching the rotor surface with hands or tools.
- Controls
- Make sure the rotor rotates easily. If it doesn't, check that the
brush seals have correct clearance and coat the brushes with silicone
oil.
- Check the drive belt for proper tension. You should not be able to
spin the drive sheave inside the belt. Tighten V-belt as required. If
tension adjustment is at maximum range, the V-belt must be shortened
and respliced.
- Protect the drive belt against damage and keep it as clean as possible.
Keep the rotor surface free from obstructions and protect from damage.
- Cleaning
- Clean rotor surface by vacuuming with a soft brush attachment. Grease
or dirt can be removed from the rotor by spraying water or a mild detergent
which is compatible with aluminum. Compressed air and low pressure steam
can also be used for cleaning.
- The maximum allowable pressure from a spray nozzle is 85 psi. The
nozzle must be kept at least 3/16" from the rotor surface.
- After cleaning the rotor, recoat the brush seals with silicone oil.
- Greasing
- All wheel ball-bearings are permanently lubricated and need no further
greasing
