Typical Process for Installing Water Piping
1. Rough-in any pipe/insulation/heat trace in areas
that will not be accessible or traversable during the
nal installation.
2. Installation of all water piping and components.
3. Pressure testing the water side components with
air to a pressure less than 150 PSI or the pressure
rating on the storage tank pressure relief valves.
Nyle recommends testing to 80-100 PSI or 1.25x
the standing pressure of the system, whichever is
higher, for a minimum of two continuous hours.
4. Find and rectify any leaks.
5. Install heat tracing and pipe insulation after the pip-
ing is determined airtight. Note this may require a
standalone pressure test of rough-in piping so insu-
lation and heat tracing can rough-in with the pipes..
6. Isolate the building piping from the heat pumps and
storage, then use purge valves to ll the system.
7. Purge lines by continuing to ll through isolated
ow paths until ll water exits a far point drain valve
in a clean and continuous stream without stuttering
or foaming.
8. After the system has operated for 24 hours includ-
ing several heat/cool cycles of the heat pump, a
nal check for water leaks should be performed.
CAUTION
Cold Climate Filling:
If the heat pump is being lled with water when ambient
temperatures may pose a freeze risk, ensure that ll-
ing the unit DOES NOT OCCUR until the 120V power
feed (or main feed, with the unied power package) is
ready, wired, and active. Unit will need power to engage
in freeze protection measures. Failure to activate the
120V power before lling it with potable water can result
in complete system failure as well as water damage or
damage to the building and other piping/components
attached to the unit.
Manual Drain Down: There is a manual valve behind
the condenser heat exchanger that can be manually
opened to drain down the heat pump. Water will drain
into the condensate pan and be removed by the con-
densate piping. Be sure isolation valving in the building
is closed before opening the manual drain valve, and
close the drain valve after water has been drained from
the heat pump. See “Unit Diagram and Key Compo-
nents” on page 13 to identify this drain valve.
Condensate Piping
Commercial heat pump water heaters can produce
large amounts of condensate during warmer weather;
in cold climates they will also create condensation run-
off during the defrost cycle. It is imperative that both
high volume summer runoff and freezing temperature
water handling are both considered in the condensa-
tion management plan.
A drain pan is installed under the evaporator coil. The
pan includes water level sensors, trace heating, and
a connection point for exterior condensate piping. The
heat pump will suspend compressor operation when
enough water is present in the drain pan, and will ini-
tiate pan heating if the ambient temperature poses a
freeze risk when water is present in the pan.
CAUTION
Nyle recommends all condensate lines be piped to
drain. Failure to control condensate can result in slip/fall
conditions, site erosion, water damage, and/or damage
to the heat pump water heater itself; which can include
complete unit failure not covered by warranty. While un-
piped applications are possible, they would need to be
able to safely accommodate signicant and sustained
condensate production, especially in humid climates.
Unpiped applications would also require a mounting
height of 12-24" (dependent on local climate) to avoid
ice damage to the heat pump in freezing conditions, as
well as routine inspection to ensure ice buildup doesn’t
threaten the unit.
