Primary Drain Installation
NOTE: Failure to follow the following procedures may result in serious property damage. A eld supplied secondary con-
densate pan or P-trap may be required. Check with local codes. In case of drainage system blockage, the unit base will
allow excess water to ow 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 two 3/4” FPT connections on the VPDP1.
2. Insert the provided 3/4” nipple into the determined connection using eld-supplied Teon tape or pipe joint
compound.
3. With the slip end of a 3/4” union, connect to the nipple with Teon tape or pipe joint compound.
4. Hand-tighten all ttings to prevent damage to unit or ttings.
5. Install a eld-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 unused connection port on the VPDP1 with the provided 3/4” pipe plug with eld-supplied Teon tape or
pipe joint compound. Hand tighten to prevent damage to the unit or ttings. Do not thread metal or copper pipe
ttings directly into unit.
7. Check the system for leaks.
