Water Connection Installation
Water Connections-Residential (Distributor) Models
Residential models utilize swivel piping
fi
ttings for water
connections that are rated for 450 psi (3101 kPa) operating
pressure. The connections have a rubber gasket seal
similar to a garden hose gasket, which when mated to the
fl
ush end of most 1” threaded male pipe
fi
ttings provides
a leak-free seal without the need for thread sealing tape or
joint compound. Insure that the rubber seal is in the swivel
connector prior to attempting any connection (rubber seals
are shipped attached to the swivel connector). DO NOT
OVER TIGHTEN or leaks may occur.
The female locking ring is threaded onto the pipe threads
which holds the male pipe end against the rubber gasket,
and seals the joint. HAND TIGHTEN ONLY! DO NOT
OVERTIGHTEN!

Tranquility
®
22 Digital (TZ) units are offered with a standard
internal variable water
fl
ow control.
The three possible alternatives are:
1)
Internal Flow Controller - For Closed
Loop Applications
Primarily for use on closed-loop applications with a
single unit. With this factory-installed standard option, the
unit is built with an Internal Variable Speed Pump and
other components to
fl
ush and operate the unit correctly
(including an expansion tank,
fl
ush ports and
fl
ushing
valves). The pump speed is controlled by the DXM2
control based on the difference in entering and leaving
water temperatures.
2)
Internal Modulating, Motorized Valve - For Open
Loop Applications
Primarily for open loop/ground water applications. With
this factory-installed option, the unit is built with an
internal motorized modulating valve, which is controlled
by the DXM2 control board based on the difference in
entering and leaving water temperatures.
3)
Internal Modulating Motorized Valve – For Closed
Loop Applications
Primarily for use on multi-unit closed loop applications
with a central variable speed pump. With this factory-
installed option, the unit includes a low pressure drop
motorized modulating valve that is controlled by the
DXM2 microprocessor control based on the difference in
the entering and leaving water temperatures.
Details on these options are included in the following sections
on ground loop and ground water applications.
