Primary Drain Installation - Friedrich VERT-I-PAK VHA09K Installation & Operation Manual

Primary Drain Installation

Supplied 3/4" plugs
Failure to follow the following procedures may result in serious property damage. A field supplied secondary condensate pan
or P-trap may be required. Check with local codes. In case of drainage system blockage, the unit base will allow excess wa-
ter to flow out of the unit through the plenum and the architectural louver. It is critical to ensure that the drainage path is not
blocked or obstructed in any way during installation.
1. The supplied drain kit must be connected to one of the three (left, right or rear) 3/4" FPT connections on the unit base pan.
Use of rear fitting without connection to DWV system (drain, waste, vent) may result in staining of the outside wall.
2. Insert the provided 3/4" nipple into the determined connection using field-supplied Teflon tape or pipe joint
compound.
3. With the slip end of a 3/4" union, connect to the nipple with Teflon tape or pipe joint compound.
4. Hand-tighten all fittings to prevent damage to unit or fittings.
5. Install a field-supplied drain system to the slip end of the union. A trap is recommended and drain connections
should be connected to building DWV system. Pitch the drain line of a 1/4" downward slope for every foot (1') of
lateral horizontal run to the DWV.
6. Plug the two unused connection ports with the two provided 3/4" pipe plugs with field-supplied Teflon tape or
pipe joint compound. Hand tighten to prevent damage to the unit or fittings. Do not thread metal or copper pipe
fittings directly into unit.
7. Check the system for leaks.
