ENGINEERING DATA
CORE
Single, engineered with aluminum for superior
thermal conductivity, meets the flame spread and
smoke developed classifications of the National
Building Code.
MOTOR

CONTROLS
• Lighted power switch
• STD / SP models have 3 speed (LOW, MED,
HIGH) blower control
• MAX models have 5 speed with Off position con¬
trolled by autotransformer
• Defrost light indicates when defrost occurs. This
is automatic when outside condition drops below
-5°C (23°F)
• 24 VAC (low voltage) override of speed control to
HIGH speed
• 150MAX, 200STD and 200MAX have a built in
dehumidistat (automatically increases ventilation
when RH[humidity] exceeds operators set point)
CODES and STANDARDS
All models are CSA approved.
All components are UL listed.
Model 200MAX is R2000 approved.
Model 200MAX is HVI Certified.
ELECTRIC DEFROST
OPERATION OF ELECTRIC DEFROST
MODELS 150SP, 200STD
These Models are equipped with an electric
defrost element and a factory pre-set automatic tem¬
perature controller in the fresh air supply stream which
work to defrost the heat exchange core as necessary.
The element will startto operate at about -5°C (23°F) as
set at the factory (user adjustable) and cycle ON and
OFFuntil about -15°C (5°F) at which time it is on until the
temperature warms up (i.e. warmer than -15°C (5°F)).
DAMPER DEFROST
OPERATION OF DAMPER DEFROST
MODELS 150MAX, 200MAX
These Models have an electronically controlled
damper defrost mechanism. If the outside temperature
drops below -5°C (23°F), the defrost timer is activated.
After waiting approximately 17 minutes (during which
time the core may experience some nominal frost build¬
up), the timer activates a motor driven damper door
mechanism which opens the defrost port while at the
same time closing off the supply air from outside. After
approximately 4.5 minutes, the damper operates in the
opposite direction to close off the defrost port and
reopen the fresh air at the supply port (See Figure #1).
The 17 minute wait time and 4.5 minute defrost cycle
repeat until the temperature again rises above -5°C
(23°F).
The defrost mechanism incorporates an easy to
"self-test " feature. Each time power to the unit is
interrupted (unplugged then plugged back in or turned
OFF then ON, etc.), the unit initiates a defrost cycle.
The defrost L.E.D. illuminates and the damper door
operates for the pre-set 4.5 minute (approximate) time
interval. This allows visual inspection of the operating
components involved in the defrost cycle as they per¬
form their function.
