CLW QUAD SERIES CHILLER INSTALLATION MANUAL
General
System piping should be kept as simple as possible to
minimize the pressure drop, but hand valves should be field
installed to facilitate unit servicing. The piping installation
should provide service personnel with the ability to measure
and/or monitor water temperatures and pressures.
Source and load fluid connections are provided with 4-inch
[10.2cm] Victaulic grooved nipples. Each nipple will also
have a PT port installed for test and balance purposes.
It will be the installing contractor’s responsibility to
adequately support incoming piping to avoid damage to the
unit’s piping or heat exchangers. The water lines should be
routed so as not to interfere with access to the unit.
Field Connected Water Piping
For any installation where the transmission of vibration
through the piping connections could cause unacceptable
noise levels in occupied spaces it is important to provide
adequate vibration damping. One method is to use the
optional Adapter Hose Kit (kit number TKC16S-4). This Kit
consists of four pieces of a braided stainless steel flexible
hose with a 4” Victaulic connection on one end and a 4”
MPT connection with pipe union on the other. Overall length
of each piece is 18”.
NOTE: Units are factory run-tested using propylene
glycol. Prior to connecting piping to unit, thoroughly flush
heat exchangers.
