Condenser Pumps and Piping
The condenser water pump(s) must be cycled off when the last
chiller of the system cycles off. This will keep cold condenser
water from migrating refrigerant to the condenser. Cold liquid
refrigerant in the condenser can make start up difcult. In
addition, turning off the condenser water pump(s) when the
chillers are not operating will conserve energy.
Include thermometers and pressure gauges at the chiller inlet
and outlet connections and install air vents at the high points
of piping. Where noise and vibration are critical and the unit
is mounted on spring isolators, exible piping and conduit
connections are necessary.
Retrot Knockdown
It is estimated that fty percent of retrot applications require partial or complete disassembly of the chiller. Magnitude
®
WMC
chillers are relatively easy to disassemble due to the small compressor size, simplied refrigerant piping and the absence of a
lubrication system with its attendant components and piping. Two knockdown arrangements, Type A shown in Figure 10 and Type
B shown in Figure 11, are available as options.
Type A Knockdown, “Bolt-Together Construction”
Chillers are built and shipped completely assembled with bolt-together construction on major components for eld disassembly
and re-assembly on the job site.
Figure 10: Type A Knockdown
Type A Scope:
• Chiller components are manufactured with bolt-together
construction designed for eld disassembly and re-
assembly on-site.
• Suction and discharge lines have bolt-on anges.
• Unit ships with vessel and/or head insulation, if ordered.
• Unit ships with full factory refrigerant charge in the
chiller.
• Unit ships completely assembled to the jobsite.
• Bolt-together construction allows for site disassembly
based on required clearances at each jobsite.
• Site disassembly and re-assembly must be supervised
or completed by Daikin Applied service personnel.
• Ideal for retrot applications.
