Multi-Function Air To Water Heat Pump
2.6 Hot water tank and buffer tank options
1.1.If the unit without a tank when leave factory, please select tanks as follow requirements
(heater in the tank, if need the tank water temperature over 60 degrees, heaters required to
be installed, need not to install if not required).
1.2.This heat pump water heater can be equipped with tank-type water heater (Figure 1) and
closed-type water heater (Figure 2).
A. Select the tank-type water heaters:
1) The tank-type water heater should be able to withstand the rated pressure of 0.03MPa.
2) If the devices capacity more than 15L, and can not be empty by a outlet which install in the
pipe, it should be equipped with a kind of emission devices, which with tools to make it work.
(Emission devices can be combined with pressure relief devices)
3) The unit without water level control output, need external water tank level control equipment.
B. Select the closed water heaters:
1) If not installed pressure relief device inside the water tank, so must be fitted with pressure
relief devices (when installed refer to the "Third, installation, 3, pipe connection"), the
parameter value is 0.7MPa.
2) The water can drain from the pressure relief device in the
outlet pipe which should keep connected with the atmosphere.
3) The pressure relief device to periodically work to remove the
calcium carbonate deposition, and sure that device is not plugged.
4) Heat pump water heater installation is complete, the water
tank empty refer to the "three, installation, 5, trial run."
5) Design an enclosed heater which directly connect to water,
the rated pressure should be at least 0.6MPa.
6) If the devices capacity more than 15L, and can not be empty
by a outlet which install in the pipe, it should be equipped with
a kind of emission devices, which with tools to make it work.
(Emission devices can be combined with pressure relief devices)
