INSTALLATION
Positioning the heater
- The heater must be positioned n such a way that there is a safe distance between f1ammable materials and the external surfaces of the heater. See Table 3.
- In nstalling the heater, it must be prevented that people could have physical contact with the heater or that other dangerous situations could emerge during the heating process.
- CLIFF Mini holds approximately 132 lb (60 kg) of stones and CLIFF holds approximately 330 lb (150 kg).
- The input of the power cable s located on the bottom cover of the heater.
Connecting the heater to the power supply
- A method to disconnect all poles from the mains (a circuit breaker) must be installed on the power circuit before the sauna controller.
- Only a certified electrician s allowed to connect the heater to the power supply.
- The power cable of the heater must meet the requirements of UL 62 n US and CSA 49 in Canada.
- It is recommended to connect the unit to the mains without an earth-leakage circuit breaker.
- The maximum current ntensity in the cross-sectional area of the cable and circuit breaker are listed in Table 1 and Table 2.
- The cable must be secured to the clamp on the cover screw.
NB! It is forbidden to use a non-heat-resistant cable with PVC isolation as the power cable. The joint box must be waterproof and it must be located up to 20 in (50 cm) from the ftoor.
- Open the cover of the heater’s electrical box.
- Attach the power cable on the terminal block according to the circuit diagram.
- Close the cover.
- Fix the cable on the output with a cable strap.
Fitting the stones
- Make sure that the heating elements are not bent during the process.
- There must be sufficient air circulation around the heater elements.
- Werecommend washing the stones before filling the receptacle.
- Stack the stones sparsely between the heating elements. If the stones have been stacked too close to each other, the heating elements may overheat (= shorter useful life) and slow the heating of the sauna.
- Stones with a diameter of 1.2-1.9 in (3-5 cm) are suitable for the heater.
- Thestones on the external surface of the heater must be stacked close to one another. The heating elements must not be visible.
- Using ceramic stones in the CLIFF heater is allowed at the user’s responsibility.
ATTENTION! Too sparsely filled stone container causes fire hazard!
NB! We recommend a specialist to lay the stones on the heater.
Removing the ribs of the heater
For fitting the stones, all of the ribs are removable by props (A).
- Onthe bottom of the heater, release the nuts of the threaded rod by 5mm.
- Pushthe props between the ribs of the heater.
- Release the rib from both ends.
- Carefully remove the rib from the joint, first from the right end and then the left.
NB! Pull the rib away from the heater without using force or turning the rib – avoid bending the tenons!
The rib under the removed rib is instantly removable in a similar fashion.
The procedure is reversed for putting the ribs back. The rib must be attached
to the joint from the left end first and then from the right.
First-time use of the sauna heater
Before switching the heater on, the nsulation resistance might prove to be
lower than the standard. The reason for that is the moisture seeped into the
insulating ayer during storage in the warehouse and transportation.
The moisture evaporates n 1-2 hours of heating the electric heater.
Controlling the heater
All certified control panels may be used in controlling the heater.
The output of the heater must remain n the interval determined by the control
panel’s producer.
Product can be used only with controlunit with timer function.
Including other than those for nstallation in public saunas. shall be provided
with a timer. For appliances for use in blocks of f1ats, hotels and similar
locations, the operating period of the sauna heater shall be limited to 12 h
with a minimum rest period of 6 h before any automatic restarting. For other
appliances, the operating period of the timer shall be imited to 6 h,
automatic restarting not being allowed.
Guard rails
-
It is recommended to construct a guard rail around the heater.
We recommend using materials with ow heat capacity and bad thermal conductivity for the guard rail. -
Upon using f1ammable materials, it is necessary to leave the specified minimal safety clearances between the heater and flammable constructions.
ATTENTION! IF THE HEATER IS INSTALLED CLOSER TO FLAMMABLE CONSTRUCTIONS THAN AT THE DISTANCE OF THE MINIMAL REQUIRED PROTECTION BELT IT MAY CAUSE A FIRE HAZARD!
SAUNA ROOM
Wall materials and insulating the sauna room
In a sauna with electric heating, all massive heat accumulating wall surfaces
(brick, glass brick, rendering etc.) must be insulated to use the electric
heater with a regular output.
The following sauna wall and ceiling construction is considered to be sufficiently insulated:
- a carefully installed nsulation wool ayer of 4 in, minimum 2 in (100 mm, min. 50 mm);
- the construction is damp proofed with taped aluminium paper or other refiective material;
- there is a 0.4 in (10 mm) air gap between the damp protection and boarding
- light wooden boards with about a 0.5-0.65 in (12-16 mm) thick ness have been used for interior finishing;
- there s an air gap of at least 0.2 n (5 mm) on the edge of the ceiling panels at the upper part of the wall panelling.
In order to use the heater with a regular output, t would be practical to bring the ceiling of the sauna lower regular 86.6 – 91 in, min. height of sauna room 86.6 in (2200-2300 mm, min. height of sauna room 2200 mm) so that the volume of the sauna room diminishes. The ceiling is insulated with an insulation layer at least 4 n (100 mm) thick and boarded according to the method described above. Wood should be used to cover internal surfaces; an exception may be made for heat resistant walls in the vicinity of the heater.
ATTENTION! Insulating the heat barrier has to be approved by the fire
inspector. Insulating ftues in use is forbidden!
NB! Covering the walls or ftoor with light protective material, for
example, mineral tiles that are installed directly on the surface of the walls
or ceiling might cause the dangerous overheating of the wall or ceiling
material.
Floor of the sauna room
The heater stones in use crumble due to temperature changes.
The pieces and pebbles breaking away from the heater stones are washed on the
sauna’s f1oor with the steam-making water. Hot stone parts may damage plastic
f1ooring under and near the heater.
Heater stone particles and sprays from the steam-making water (e.g., with iron
content) may absorb into the light joints of a tile f1oor. In order to avoid
aesthetic damage (caused by the reasons mentioned above), ceramic tiles and
dark joint filler should be used under and around the heater.
Ventilation of the sauna
- In order to guarantee a sufficient supply of oxygen and fresh air. the sauna’s ventilation must be as efficient as possible. t is advisable to direct the fresh air into the sauna room from above the heater stones.
- As an alternative. the fresh air may be directed in from under the heater.
- The air nlet must be equipped with an adjustable valve.
- The exhaust valve must be installed n the opposite wall from the inlet valve at least 7.9 n (20 cm) above the height of the inlet valve.
- It is advised to install a ventilation valve at the upper part of the sauna room for the final ventilation
WARNING !
- Before turning on the electric heater. always check the sauna room and heater.
- The heater may be used only when it has been correctly filled with stones.
- Do not cover the heater-this causes fire hazard.
- Do not touch a working heater, it causes burns.
- Incorrect ventilation of the sauna room may dry the wood too much and cause a fire hazard n the sauna.
- Only tap water may be used for making steam.
- Never make steam by using a water hose.
- There must always be at least 2 in (5 cm) of fireproof heat insulation under the boarding.
- Sauna doors must always open outwards.
- Do not use the sauna for a purpose it is not ntended for.
- Do not install more than one heater nto the sauna room.
- Undiluted sauna essences etc. may gnite when poured directly onto the stones.
- Do not leave small children unattended n the sauna.
- Sudden cooling after staying in the steam room is not recommended for people with poor health. Consult a doctor.
- Enjoy the sauna as ong as it is comfortable for you.
- Keep this nformation at a safe place.
