CAUTIONS:
1. Do not connect supply line to condenser water outlet and return line to inlet.
2. Be sure to install water drain valve on piping.
3. Be sure to install pump on supply line, not return.
4. On city or waste water systems, install strainer to remove foreign matters.
5. Recirculating systems with low temperature water (city or well water) returning to condenser requires a
water requlating valve.
6. Provide plugged tees on outlet pipe for cleaning.
Condensate Drain
- Requires standard pipe connected to the condensate pan nipple. Pitch down to open drain.
Provide trap 70 mm high (100 mm on 50BL050-080) and plugged tees for cleaning. Observe all local sanitary
codes.
Rearrangement of Connections
- The direction of water piping connections can be changed (revered).
PROCEDEURE:
1. Remove the hexagonal nut (6).
2. Take off and exchange (1) and (2) with (3) and (4) (water head covers and gaskets).
3. Fasten the bolts (5) and nuts (6).
Take care not to erroneously position head covers and gaskets. Check for water leaks.
Air Duct Connection
Supply Air Duct
- Connect the flanged discharge openings to the supply duct using a flexible (canvas) connection
to prevent vibration. Support and fix the duct so that the weight of duct should not be borne by unit.
Return Air Duct
- Attach matching flanges on the return air opening and connect return air duct thru a canvas
connection. If outdoor air is to be introduced, connect outdoor air duct to the return air duct. Install an outdoor
makeup air damper in the outdoor air duct. Install ductwork so that space for servicing can be available.
