Model ERCH-HP Energy Recovery Unit
Start-Up Unit
DANGER
Electric shock hazard. Can cause injury or death.
Before attempting to perform any service or
maintenance, turn the electrical power to unit to OFF
at disconnect switch(es). Unit may have multiple
power supplies.
CAUTION
Use caution when removing access panels or other
unit components, especially while standing on a
ladder or other potentially unsteady base. Access
panels and unit components can be heavy and
serious injury may occur.
CAUTION
Do not operate without the filters and birdscreens
installed. They prevent the entry of foreign objects
such as leaves, birds, etc.
CAUTION
Do not run unit during construction phase. Damage to
internal components may result and void warranty.
WARNING
• Unit was factory tested. All blowers, fans,
and compressors are set-up to run correctly
when supplied power. If any one fan is running
backwards or the compressor is making loud
noises, immediately turn off the power. Switch two
leads on the incoming power to the disconnect.
This will ensure proper operation of the unit.
Failure to comply may damage the compressors
and void the warranty.
• Do not jumper any safety devices when operating
the unit. This may damage components within or
cause serious injury or death.
• Do not operate compressor when the outdoor
temperature is below 40ºF.
• Do not short-cycle the compressor. Allow
5 minutes between “on” cycles to prevent
compressor damage.
• Prior to starting up the unit, power must be
energized for 24 hours without a call for cooling
to allow the compressor crankcase heaters time
to boil off any liquid refrigerant present in the
compressor.
• DX system is charged with refrigerant. Start-up
must be performed by EPA Certified Technician.
Every installation requires a comprehensive start-up
to ensure proper operation of the unit. As part of that
process, the following checklist must be completed and
information recorded. Starting up the unit in accordance
with this checklist will not only ensure proper operation,
but will also provide valuable information to personnel
performing future maintenance. Should an issue arise
which requires factory assistance, this completed
document will allow unit experts to provide quicker
resolve. Qualified personnel should perform start-up to
ensure safe and proper practices are followed.
