SYNERGY3D INSTALLATION MANUAL
The duct system should be sized to handle the design
airflow quietly. To maximize sound attenuation of the unit
blower, the supply and return plenums should include inter-
nal duct liner of glass fiber or be of ductboard construction
for the first few feet. If air noise or excessive airflow is a
problem, the blower speed can be changed. See the Blower
Performance and Blower Speed sections.
Water Piping
The proper water flow must be provided to each unit
whenever the unit operates. To assure proper flow, use
pressure/temperature ports to determine the flow rate.
These ports should be located at the supply and return
water connections on the unit. The proper flow rate cannot
be accurately set without measuring the water pressure drop
through the refrigerant-to-water heat exchanger.
All Synergy3D source water connections are swivel piping
fittings that accept a 1 in. Male Pipe Thread (MPT) (see
Female Locking Ring illustration). The swivel pipe connector
has a rubber gasket seal similar to a garden hose gasket,
which when mated to the flush end of 1 in. threaded pipe
provides a leak-free seal without the need for thread sealing
tape or compound. Check to ensure that the rubber seal is
in the swivel connector prior to attempting any connection.
The rubber seals are shipped attached to the water line.
To make the connection to a ground loop system, mate
the brass connector (supplied in CK4LI and CK4L-GLI
connector kits) against the rubber gasket in the swivel
connector, and thread the female locking ring onto the
pipe threads, while maintaining the brass connector in the
desired direction (see Female Locking RIng illustration).
Tighten the connectors by hand and then gently snug
the fitting with pliers to provide a leak proof joint. When
connecting to an open loop (ground water) system, thread 1
in. MPT fitting (schedule 80 PVC or copper) into the swivel
connector and tighten in the same manner as noted above.
The open and closed loop piping system must include
pressure/temperature taps for serviceability.
Never use flexible hoses smaller than 1 in. inside diameter on
the unit and limit hose length to 10 ft. per connection. Check
carefully for water leaks.
