Notice –Warnings
To use this product better and more safely, please read this manual carefully before
installation and initial operation. Save this manual for future reference.
Thisheat pump must beinstalledbyqualified and experienced technicians/trade-
persons. ImproperInstallation of this heat pump may cause damage and danger.
This heat pump must beinstalledin accordance with local wiring regulations including, an
isolating switch from the supply mains and grounded power supply consistent with the
power specification ofthis heat pump.
The installation of this heat pump must comply with the model's wiring chart in this
manual, and its power requirements as stated on the rating label on the side of the heat
pump.
Donot install this heat pump close to flammable or explosive materials, or open flames.
Checking and cleaning of the evaporator fin coil regularly is recommended for good and
efficientair flow.

Installation
Heat Pump Installation
This heat pump requires good air flow through the fin coils for maximum efficiency. Also, hotter outside air
temperature in cooling mode and colder outside air temperature in heating mode will reduce performance of the
heat pump. Therefore, the hot/cold discharged air in cooling/heating modes from the heat pump should not be
allowed to deflect back to the air inlet.
Please keep enough space around the heat pump for repairs and maintenance.

Installation Considerations:
•The installation position should have good ventilation.
•The installed heat pump should not make extraneous noises or rattling sounds.
•Try to minimize direct sunlight onto the unit.
•Water from rain or defrost mode will be discharged through a drain hole in the base plate. So, the unit must
be raised in freezing climates to avoid ice buildup.
•The outlet air position should not face into a prevailing wind direction, or this will reduce performance
efficiency.
•Try to position the heat pump so the outlet air does not discharge directly onto a fence or towards a
neighbor.
•The installation position should not be located next to flammable materials, explosive materials, or open
flames.
•The heat pump should be protected from oil (such as engine oil in a factory environment), salt (such as sea
spay or salty air) and/or sulfides (that may be present in the air from industrial activity or a thermal spring).
•The heat pump should ideally be installed on a raised stand, preferably secured to a concrete pad. Alternately,
the heat pump can be installed on a balcony, ledge, wall, or roof provided there is a suitable load-bearing
platform in place capable of supporting the weight of the unit and not transmitting vibration noise.
•There should be a drainpipe or channel from the heat pump to take the condensate water away from the unit.
•Do not install the control panel in a wet environment which may cause the control panel to malfunction.
•In cold regions where the heat pump will be used primarily for heating, the unit should be raised off the ground 18-
24” to allow ice accumulation below the drain hole, otherwise drain pan will become plugged.
