3. Safety This water heater must not be operated at ambient temperatures in excess of 42 °C (107 °F) or below 6 °C (43 °F). If outside air is directly drawn in ensure, that the water heater is isolated from its power supply when the air temperature falls below 6 °C (43 °F). This chapter provides an overview of all important actions required for a safe and trouble-free operation. 3.1 General safety instructions Operate the water heater only when fully installed and with all safety equipment in place.
OPERATION WATER HEATER DESCRIPTION 4. Water heater description This water heater is an automatic hot water generator with approx. 303 l (80 gallon) capacity. The hot water temperature is factory set to 60 °C (140 °F). After opening a hot water faucet, the hot water is pushed out of the water heater by the incoming cold water. This water heater works like an air conditioner but does not need to be vented. The water heater extracts heat from the ambient air to heat the water.
7.2 ... the safety valve of the cold water supply line is dripping This unit can operate up to 0.48 MPa (70 psi) of inlet pressure. Expansion water drips from the safety valve during heat-up. This is completely normal. Notify your local licensed installer if water still drips after heat-up has been completed. 7.3 ... the condensate drain drips This is quite normal and always happens when the surface temperature of the evaporator is lower than the dew point temperature of the ambient air. 1 1 6.
OPERATION WATER HEATER DESCRIPTION WARNING Injury Moving parts represent a risk of injury. » Before opening the water heater, ensure that the fan has come to a complete standstill. 8.
INSTALLATION INSTALLATION 10. Installation 10 CAUTION Injury Incorrect installation can result in severe injuries and material losses. Prior to installation ensure you have adequate space for the work to be carried out. Handle components with sharp edges carefully. The sheet steel casing of the water heater is not designed to withstand heavy forces. Handle and install the water heater with care. 10.
INSTALLATION INSTALLATION (15,75") 10.2 Shipping inspection » Upon receipt, check your delivery for completeness and possible transport damage. If transport damage is visible, proceed as follows: - Do not accept the delivery or only with reservations. - Note down the extent of the damage on the shipping documents or on the delivery note of the carrier. - Initiate a complaint. Immediately give notice of any damage. Give notice of all damage as soon as it has been identified.
DANGER Injury from overturning Secure the water heater against overturning by getting a second person to support the water heater. » Push a wooden support underneath the lower part of the packaging. » Break out the free semi-shell of the lower section of the packaging. » Push two polystyrene® installation aids with the step-shaped corner underneath the water heater. The water heater is subsequently set and tilted onto this profile.

10.7 Water connection The water connection must be carried out by a qualified licensed plumber. The cold water connection must comply with DIN 1988 [or state and local codes] » Prior to installing the water heater, flush the line thoroughly. 8 5 Hot water C M 6 H 12 2 15 Install a 0.48 MPa (70 psi) pressure reducing valve on the cold water inlet. Accurately maintain the order of fittings on the cold water side (see diagram 10.7). 10.7.

INSTALLATION INITIAL START-UP ENGLISH 12.2 Knob settings 11. Initial start-up 11.1 Initial start-up Only approved, licensed installers may perform the initial start-up of this water heater, and instruct the user in its operation. » Fill and vent the water heater. For this, open the cold water supply and one hot water tap. » Thoroughly flush the water heater. » Check the safety valves. Inform the user that water may drip from the safety valve while water is being heated up.
INSTALLATION MAINTENANCE AND CLEANING The safety high pressure limiter shuts down the compressor if the pressure inside the refrigerant circuit exceeds the permissible maximum value. The safety high pressure limiter may also trip if the water heater is operated above its permissible limit, i.e. above an air temperature of 42 °C (107 °F). (See above) The safety pressure limiter also trips if the heat pump thermostat fails.
INSTALLATION MAINTENANCE AND CLEANING 15.4 Descaling ENGLISH » Close the shut-off valve in the cold water supply to the tank. » Draw water from the tank to relieve the pressure inside the water heater. 1 3 1 2 3 26_03_01_1025 CAUTION : Risk of electric shock Use copper conductors only 2 Low pressure fill port High pressure fill port Booster heater flange » Unscrew the booster heater flange and remove element.
