Unit Installation
Installation of Supply and Return Piping
Follow these piping guidelines.
1. Install a drain valve at the base of each supply and
return riser to facilitate system fl ushing.
2. Install shut-off / balancing valves and unions at each
unit to permit unit removal for servicing.
3. Place strainers at the inlet of each system
circulating pump.
4. Select the proper hose length to allow slack between
connection points. Hoses may vary in length by +2%
to -4% under pressure.
5. Exceeding the minimum bend radius may cause the
hose to collapse which reduces water fl ow rate. Install
an angle adapter to avoid sharp bends in the hose
when the radius falls below the required minimum
and causes a slight kink.
PIPING INSTALLATION
Insulation is not required on loop water piping except
where the piping runs through unheated areas or outside
the building or when the loop water temperature is
below the minimum expected dew point of the pipe
ambient temperature. Insulation is required if loop
water temperature drops below the dew point.
Pipe joint compound is not necessary when Tefl on
threaded tape is pre-applied to hose assemblies or when
fl ared-end connections are used. If pipe joint compound
is preferred, use compound only in small amounts on the
pipe threads of the fi tting adapters. Prevent sealant from
reaching the fl ared surfaces of the joint.
TMW Unit Location - These units are not designed for
outdoor installation. Locate the unit in an INDOOR
area that allows enough space for service personnel to
perform typical maintenance or repairs.
The installation of water source heat pump units and
all associated components, parts and accessories
which make up the installation shall be in accordance
with the regulations of ALL authorities having
jurisdiction and MUST conform to all applicable codes.
It is the responsibility of the Installing Contractor to
determine and comply with ALL applicable codes and
regulations.
Locate the unit in an indoor area that allows easy removal
of access panels, and has enough space for service
personnel to perform maintenance or repair. Provide
suffi cient room to make water and electrical connections..
Any access panel screws that would be diffi cult to
remove after the unit is installed should be removed
prior to setting the unit. These units are not approved
for outdoor installation and, therefore, must be installed
inside the structure being conditioned. Do not locate
in areas where ambient conditions are not maintained
within 40-100°F [4-38°C].
WARNING!
WARNING! Piping must comply with all applicable codes.
WARNING!
WARNING! Do not bend or kink supply lines or hoses.
Note: When anti-freeze is used in the loop, assure
that it is compatible with Tefl on tape or pipe joint
compound employed.
Maximum allowable torque for brass fi ttings is 30 ft-lbs
[41 N-m]. If a torque wrench is not available, tighten
fi nger-tight plus one quarter turn. Tighten steel fi ttings
as necessary.
