IMPORTANT INSTALLERS NOTE
The Installer MUST be familiar with the features of the VAV and the installation
process BEFORE INSTALLATION COMMENCES.
Zonemaster/Polyaire does not take responsibility for poorly designed or
installed VAV systems. Neither will we take responsibility for customer
complaints due to poor design and installation. We strongly suggest that any
installer wishing to install a Zonemaster VAV system should fully acquaint
himself with the design features and capabilities of the system before
commencing the job , either by reading the installation manual thoroughly
or consulting with a Polyaire staff member conversant with this system
(Preferably both). Contact Polyaire re VAV installation training.
INSTALLATION TIPS & COMMON PROBLEMS
1. The VAV power transformer(s) are fitted with 3 pin plugs and should be
plugged in to their own power point separate from the A/C unit.
DO NOT remove the plug and hard wire the VAV to the A/C power supply as
the wide fluctuations in the A/C current will damage the VAV unit.
2. Don’t get confused between Data and Control Cables.
The packages are clearly marked. Data Cable has left latched plugs and
Control cable has centre latched plugs
3. Always check cables: Particularly if making up your own cables. Cables and
plugs can sometimes get twisted or be faulty, the wires and contacts are very
small. To ensure that all cables are ok pre- test with Zonemaster Cable Tester
(Available from Polyaire). This will help eliminate faults before (rather than
after) installation.
4. Do not tape over the button at the bottom of the damper blade when attaching
flexible duct. This is easy to do and will stop the damper turning freely.
5. All zones MUST have their own unique address allocated via the touchpad.
IE: If there are 6 zones the system must have 6 addresses.
6. Do not plug 2 touch pads into one 3 way plug.
7. VAV systems should only be fitted to Flexible duct with large enough diameter
to easily take the required volume of air. Small duct creates excessive noise
and vortex draughts and doesn’t allow the system to regulate properly.
8. Return Air Grilles should be positioned in the same space as the designated
“Spill” zone to ensure the VAV sensor can operate properly.
9. Substantial differences in zone temperature will only be achieved in separate
zones if these are effectively separated from other zones. IE Doors must be
closed to prevent cross flow from room to room.
10. The end user should be fully informed on the unit at time of commissioning so
that they fully understand the operation of the VAV unit. The end user should
be encouraged to read the user manual.
