Step-by-step installation instructions
q
Verify that maximum flow of hot water into the
DRANE-KOOLER does not exceed 6 U.S.
gallons per minute (gpm) (22.7 L/m).
q
Note that there are three connections to be made
to the DRANE-KOOLER:
Cold water supply
Hot water inlet (from a humidifier or other
appliance)
Tempered water piping to drain
q
Position the DRANE-KOOLER to allow the
most direct path of piping to minimize fittings
(see the piping diagrams on Pages 6-7).
q
Position unions on all connections as close to the
DRANE-KOOLER as possible to make cleaning
and maintenance easier.
q
Cold water supply connection instructions:
Cold water supply connection on valve is
3/8" (DN10) NPT.
Pipe a 3/8" (DN10) line directly to the
DRANE-KOOLER from the main water
supply line.
TO ENSURE ADEQUATE WATER
PRESSURE TO THE DRANE-KOOLER, DO
NOT CONNECT TO A SUPPLY WATER
LINE THAT IS DEDICATED TO OTHER
APPLIANCES.
If installing the DRANE-KOOLER with a
humidifier, do not branch off the 1/4" (DN8)
cold water supply line to the humidifier.
Verify that the supply water pressure to the
valve is at least 25 psi (172 kPa) and not more
than 80 psi (552 kPa).
Install a cold water supply union as close to
the DRANE-KOOLER as possible.
Install a cold water shut-off valve before the
union in the cold water supply line.
q
Hot water inlet connection instructions:
Hot water inlet connection is 1" (DN25) NPT.
Locate a union as close to the
DRANE-KOOLER as possible
Run 1" (DN25) pipe as directly as possible
from the hot water appliance (humidifier) to
the DRANE-KOOLER. If the piping to the hot
water inlet has a horizontal run, maintain a
pitch to the DRANE-KOOLER of at least
1/8"/ft (1%).
q
Tempered water (to drain) connection
instructions:
Tempered water outlet connection is
2" (DN50) NPT.
Install a union as close to the
DRANE-KOOLER as possible.
Run a 2" (DN50) pipe as directly as possible
from the DRANE-KOOLER to the drain.
Maintain a pitch to drain of at least 1/8"/ft
(1%).
Make sure there is a 1" (25 mm) air gap
between the drain piping and the drain.
