Unit placement
If unit cabinet assembly includes factory provided risers, and "no" field provided between-the-floor
riser extensions, please move to Step 1.
Note:
Risers are designed to accommodate a maximum of 1 1/2" to 3" expansion and contraction.
If the total calculated riser expansion exceeds 3", expansion devices must be field provided.
If unit cabinet assembly includes factory provided risers and field provided between-the floor riser
extensions are required, install the extensions before installing the cabinet.
1. Install drain valve, shut-off balancing valves, flow indicators and drain at the base of each supply
and return riser to enable system flushing at start-up, balancing and service maintenance.
2. Lift cabinet into space while aligning it into the 3"swage of the riser below.
Note:
Take extra care as not to scrape or dent risers during positioning. The riser should fall
approximately 2" into the 3" swage. This will allow for the variation in floor-to-floor dimensions,
and keep the riser joints from bottoming out.
3. Level the cabinet
4. Plum bribers in two planes to as sure proper unit operation and condensate drainage.
5. Anchor all units into place.
6. For field provided risers, center the supply/return stubou is into the unit expansion slots. The
stubou is ahold be perpendicular to the cabinet panel.
7. Verify all risers are vertical and that they penetrate the swaged joint at least 1". Riser should not
be allowed to bottom out.
8. Braze riser joints. Sot solder or low-temperature alloys should not be used in this application.
9. If risers are field provided, it is recommended that the risers be anchored to the building structure
with a minimum of one contact point. For expansion and contraction reasons, do not fasten risers
rigidly to the building.
10. Seal access holes made through the cabinet for piping with suitable material to help eliminate
air leakage.
