Power Cord Installation
All 265V PTAC/PTHP units come with a factory installed non-LCDI
power cord for use in a subbase.If the unit is to be hard-wired refer to
the instructions below.
NOTE: It is recommended that the PXSB subbase assembly,the
PXCJA conduit kit (or equivalent) be installed on all hardwire
units.If installing a flush-floor mounted unit,make sure the
chassis can be removed from the sleeve for service and
maintenance.
To install the line voltage power leads and
conduit to chassis, follow the instructions
below.
1. Follow the removal process of the chassis’s junction box.
2.
Prepare the 265V(or 230V) power cord for connection to the
chassis’ power cord connector by cutting the cord to the
appropriate length.Power cord harness selection shown on Table
2 on page14.
WARNING
Electrical Shock Hazard
Turn off electrical power before service
or installation.
ALL electrical connections and wiring
MUST be installed by a qualified
electrician and conform to the National
Code and all local codes which have
