2. INSTALLATION
2.1 Ducting Arrangement
Tools and Instruments – General tools for
ducting.
Connection – Pre-drilled duct flanges are
provided at the supply and return air duct
connections. A field-supplied or optional filter box
with filter must be installed at a proper location in
the return air duct. It is recommended that flexible
duct connections be installed to minimize sound
and vibration transmission. All ducts running
outside must be sufficiently insulated and
weatherproofed.
2.2 Condensate Drain Piping
Tools and Instruments – General piping tools.
Drain Trap – A female piping thread screw
connection is provided at side of the unit.
Dimension "L" in Fig. 5 should be sufficiently
longer than the negative fan pressure at the drain
connection (50mm to 100mm, depending on the
return air duct design). Always fill the trap with
water.
