freewatt PLUS • boiler and MCHP unit will produce
condensate at rates up to 2 ½ US quarts per hour.
Make provisions to drain condensate away from both
boiler and MCHP to ensure proper operation. Boiler
is supplied with factory-installed drain trap assembly
with ½” dia. Sch. 40 PVC connection.
Install MCHP condensate line directly into condensate •
pump, located directly behind MCHP unit, if fl oor drain
is not available. Condensate line should have “Y
connector” to ensure tubing is open to atmosphere,
removing chance for air lock in line. Figure 8-10.
Route boiler’s condensate line behind MCHP unit and
install directly into condensate pump.
Supplied boiler condensate vent drain T must be used. •
Do not make any additional electrical connections •
within freewatt PLUS System for 120 VAC power.
Separate junction box and receptacle should be
provided if 120 VAC power is required for condensate
pump.
Review installation instructions for boiler and HONDA •
MCHP to ensure a proper installation.
8.11 Onix Clamps
Do not use screw gun or wrench to tighten TorqueTite •
clamps.
Safety glasses must be worn when installing SelfTite •
Clamps.
Minimum bending radius of ½” Onix tubing is 4”. •
Onix requires special Torque-Tite or Self-Tite •
mechanical clamps, designed for higher temperature
and burst pressure ratings.
Self-Tite clamps are supplied with • freewatt PLUS
System.
TorqueTite clamps are heavy-duty screw-type, •
wide-band, stainless steel clamps. In. per lb. torque
wrench is required to install. Tightened each clamp
according to proper torque setting for size of clamp
used. Torque settings are listed on instruction
sheet supplied with clamps.
Do not over tighten TorqueTite clamp. •
Overtightening may cause long-term damage to
Onix tubing and/or to clamp itself.
SelfTite Clamps are chrome-vanadium, constant •
tension clamps. Watts Radiant recommends using
SqueezeTite pliers to properly open and install clamps.
Do not allow clamp to fl atten while being held open. •
Flattened clamps will not fi t properly over Onix and
barb assembly.
