Heat Pump Energy Saving Tips
If you do not plan to use hot water for a prolonged period, then you might choose to turn the heat
pump off or decrease the temp. setting of the control several degrees to minimize energy
consumption.
We offer the following recommendations to help conserve energy and minimize the cost of operating
your heat pump without sacrificing comfort.
1. A maximum water temp. of 60°C is recommended.
2. It is recommended to turn off the heat pump when ambient air temp. is less than -30℃ or if on
vacation for longer than a week.
3. To save energy, it is recommended that the heat pump is operated during daytime when the
ambient temp. is higher.
4. Try to install the heat pump at the ventilated places indoor. If it must be installed outdoor, where
possible, shelter the heat pump from prevailing winds, rain and snow. Always use a shelter when
practical, which will reduce the possibility of frosting and icing.
General Installation Information
1. Installation and service must be performed by a qualified installer or service agent, and must
conform to all national, state, and local codes and/or safety regulations.
2. This EVI DC Inverter Air Source Heat Pump is specifically designed for domestic hot water &
house heating.
Section 1 Introduction
Product Overview
EVI DC Inverter Air Source heat pumps transfer heat from the ambient air to water, providing high-
temp. hot water up to 60°C. The unique high-temp. heat pump is widely used for heating homes.
With innovative & advanced technology, the heat pump can operate very well at -30℃ambient temp.
with high output temp. up to 60℃, which ensures the compatibility with normal sizedradiator-based
systems without supplementation. Compared with traditional oil/LPG boilers, EVI DC
Inverter heat
pump produces up to 50% less CO2 whilst saves 80% running cost.
Our heat pumps are not only highly efficient, but also easy and safe to operate.
General Features
1. Low running costs and high efficiency
·A high coefficient of performance (COP) of up to 5 results in lower running costs compared with
traditional ASHP technology.
·No immersion heater supplement is required.
2. Reduced Capital Costs
·Simple installation
3. High Comfort Levels
·High storage temp. results in increased hot water availability.

4. No potential danger of any inflammable, gas poisoning, explosion, fire, electrical shock which are
associated with other heating systems.
5. A digital controller is incorporated to maintain the desired water temp.
6. Long-life and corrosion resistant composite cabinet stands up to severe climates.
7. American Copeland compressor ensures outstanding performance, ultra-energy efficiency,
durability and quiet operation.
8. Self-diagnostic control panel monitors and troubleshoots heat pump operations to ensure safe
and reliable operation.
9. Intelligent digital controller with friendly user interface and blue LED back light.
10. Separate isolated electrical compartment prevents internal corrosion and extends heat pump
life.
11. The heat pump can operate down to ambient air temp. of -30℃。
Section 2 Installation
The following general information describes how to install the EVI DC Inverter air source heat
pump.
Note: Before installing this product, read and follow all warning notices and instructions.
Only a qualified service person should install the heat pump.
Materials Needed for Installation
The following items are needed and are to be supplied by the installer for all heat pump
installations:
1. Plumbing fittings.
2. Level surface for proper drainage.
3. Ensure that a suitable electrical supply line is provided. See the rating plate on the heat pump
for electrical specifications. Please take a note of the specified current rating. No junction box is
needed at the heat pump; Connections are made inside of the heat pump electrical
compartment. Conduit may be attached directly to the heat pump jacket.
4. It is advised to use PVC conduit for the electrical supply line.
5. Use a booster pump for pumping water in case of low water pressure.
6. A filter on the water inlet is needed.
7. The plumbing should be insulated to reduce its heat loss.
Note: We recommend installing shut-off valves on the inlet and outlet water connections for ease of
serviceability.

Correct installation is required to ensure safe operation. The requirements for heat pumps include
the following:
1. Dimensions for critical connections.
2. Field assembly (if required).
3. Appropriate site location and clearances.
4. Proper electrical wiring.
5. Adequate water flow.
This manual provides the information needed to meet these requirements. Review all application
and installation procedures completely before continuing the installation.

Installation Location
CAUTION!
1. DO NOT install the heat pump near to hazardous materials and places
2. DO NOT install the heat pump under deep sloping roofs without gutters which will allow rainwater,
mixed with debris, to be forced through the unit.
3. Place the heat pump on a flat slightly pitched surface, such as concrete or fabricated slab. This
will allow proper drainage of condensation and rainwater from the base of the unit. If possible, the
slab should be placed at the same level or slightly higher than the filter system/equipment.
Installation Details
All criteria given in the following sections reflect minimum clearances. However, each installation
must also be evaluated, considering the prevailing local conditions such as proximity and height of
walls, and proximity to public access areas. The heat pump must be placed to provide clearances
on all sides for maintenance and inspection.
1. The heat pump installation area must have good ventilation and the air inlet/outlet must not be
hindered.
2. The installation area must have good drainage and be built on a solid foundation.
3. Do not install the unit in areas accumulated with pollutions like aggressive gas (chlorine or
acidic), dust, sand and leaves etc.
4. For easier and better maintenance and troubleshooting, no obstacles around the unit should be
closer than 1m. And no obstructions within 2m, vertically, from the unit for air ventilation. (See
Figure 1)
Figure 1
5. The heat pump must be installed with shockproof pads to prevent vibration and/or imbalance.
6. Even though the controller is waterproof, care should be taken to avoid direct sunlight and high
temp. In addition, the heat pump should be placed to ensure quality viewing of the controller.

7. The plumbing pipes must be installed with proper support to prevent possible damage due to
vibration.
Running water pressure should be kept over 196kpa. Otherwise, booster pump should be installed.
8. The acceptable operating voltage range should be within ±10% of the rated voltage.
⚫The heat pump unit must be grounded /earthed for safety purposes.
Drainage and Condensation
Condensation will occur from the evaporator when the unit is running and drain at a steady rate,
depending upon ambient air temp. and humidity. The more humid the ambient conditions, the more
condensation will occur. The bottom of the unit acts as a tray to catch rainwater and condensation.
Keep the drain holes, located on the bottom pan of the unit base, clear from debris at all times.
Suggested Installation Methods
1. For heating + hot water installation
1) System installation diagram (see Figure 2).
2) Electrical wiring diagram (see Figure 3). (If you don’t install auxiliary heating, DO n ot
c o n n e c t point 1,4 AC contactor）
3)Controller panel setting (see Figure 4, Figure 5, and Figure 6). Figure 4 shows that it is running
in hot water mode, Figure 5 /Figure 6 shows that it is running in heating or cooling mode.
4) 3-way valve: For domestic hot water mode, 3-way valve powers on. For underfloor heating or
cooling, 3-way valve powers off.
5) When both heating (or cooling) and domestic hot water don't reach the setting temp., hot water
is priority.
a) The hot water tank with coil for domestic hot water should be specially customized.
b) The heat exchange capacity of the coil should be ≥the rated heating capacity of the heat pump.
c) The head of the circulation pump should be big enough. Its actual water flow cannot be less than
water flow on nameplate.
