IBM 1756, Installation And Maintenance Manual

Page: 32 / 104

Use quick-connect couplings to attach the hoses to the heat exchangers. Hose
couplings that connect to the heat exchanger must have the following
characteristics:
v The couplings must be constructed of passivated 300-L series stainless steel or
brass with less than 30% zinc content. The coupling size is 19 mm (0.75 in.).
v
The supply hose must have a Parker (male) quick-coupling nipple, part number
SH6-63-W, or equivalent. The return hose must have a Parker (female)
quick-connect coupling, part number SH6-62-W, or equivalent.
v
If a low impedance quick-connect coupling is used at the opposite (manifold) end
of the hose, use positive locking mechanisms to prevent loss of water when the
hoses are disconnected. The connections must minimize water spill and air
inclusion into the system when they are disconnected.
