Coils (All Sizes)
Installation of Water Coil Piping
Guidelines for the installation of the coil have been provided to ensure proper performance of the coils and their
longevity. These are general guidelines that may have to be tailored to meet the specific requirements of any one
job. As always, a qualified party or individual should perform the installation and maintenance of the coil. Protective
equipment such as safety glasses, steel toe boots and gloves are recommended during the installation and
maintenance of the coil.
All field piping must be self-supporting. System piping should be flexible enough to allow for the thermal expansion
and contraction of the coil.
Water Coil Installation Recommendations
1. Piping should be in accordance with accepted industry standards. Always use a back up wrench on the coil
connections when attaching the piping to the coil if pipe thread connections are utilized.
2. Pipe sizes for the system must be selected on the basis of the head [pressure] available from the circulating pump.
3. Internal coil plumbing: Standard Vektor-M series under each fan there is a raised, insulated cover panel to be
used when internal pipe connections are desired. For the Vektor-C series 20-60, there is an insulated panel set
into the floor. Either remove this panel to run plumbing or punch appropriately sized holes in the panel to allow
piping to pass without rubbing and space for piping insulation, sealant and grommets (by others).
4. For C series, external piping connections, holes will need to be field drilled in the side of the ERS plenum. Drill
appropriately sized holes in the panel to allow piping to pass without rubbing and space for piping insulation,
sealant and grommets (by others).
5. Connect the water supply to the bottom connection on the air leaving side and the water return to the top
connection on the air entering side.
6. The air vent at the uppermost point should be temporarily opened during system start-up to release all of the air
from the coil. To maintain heat transfer capacity, periodically vent any air in the coil.
7. Water coils are not normally recommended for use with entering air temperatures below 40°F. Glycol solutions or
brines are the only freeze-safe media for operation of water coils for low entering air conditions.
8. Two-position control valves, modulating valves, three-way valves or a combination of these controls can
accomplish control of water coils. Follow the recommendations of the control manufacturer regarding types,
sizing and locations.
